National Health and Wellness Commission: Adding antigen detection as a supplement to nucleic acid to improve early warning sensitivity.

CCTV News:A few days ago, the State Council organized and formulated the "Covid-19 Antigen Detection Application Scheme (Trial)" in response to the comprehensive group of novel coronavirus epidemic prevention and control mechanism, and decided to add antigen detection as a supplement on the basis of nucleic acid detection. What is antigen testing? What are the suitable populations for antigen testing? Can self-test results replace nucleic acid results? Let’s look at the expert’s interpretation.

According to the person in charge of the Clinical Laboratory Center of the National Health and Wellness Commission, compared with nucleic acid detection, antigen detection can be faster and more convenient to operate, but its accuracy is lower, and it is generally used in the early stage of infection.

Li Jinming, Deputy Director of Clinical Laboratory Center of National Health and Wellness Commission:Because there are four kinds of structural proteins in COVID-19, the protein N is the largest in COVID-19 (among structural protein antigens), and it will be released in our pharynx after infection, so we can determine whether it is possible to infect Covid-19.

Experts said that nucleic acid detection is still the basis for the diagnosis of Covid-19 infection, and antigen detection as a supplementary means can be used for screening specific people, which is conducive to improving the ability of "early detection".

Li Jinming, Deputy Director of Clinical Laboratory Center of National Health and Wellness Commission:Antigen testing can’t replace nucleic acid testing, but it can find out the possible source of infection in time, and then do nucleic acid-related testing.

The relevant person in charge of the National Health and Wellness Commission said that at present, due to the superposition of imported cases and local cases, the current epidemic situation in China is in a state of local gathering and multi-distribution. According to the characteristics of transmission in Omicron, the monitoring mode of "antigen screening and nucleic acid diagnosis" should be popularized, so that people can buy their own tests, which is conducive to early detection and improve the sensitivity of monitoring and early warning.

Li Jinming, Deputy Director of Clinical Laboratory Center of National Health and Wellness Commission:Because (cases) are scattered, how to control them, so it is the most important application scenario to push out antigens at this time.

Three types of people are suitable for antigen testing: first, people who go to primary medical and health institutions and have symptoms such as respiratory tract and fever within 5 days; Second, isolated observers, including those in home isolation observation, close contact and sub-close contact, entry isolation observation, closed control area and control area; Third, community residents who have the need for antigen self-testing.

Li Jinming, Deputy Director of Clinical Laboratory Center of National Health and Wellness Commission:Although antigen detection is not as sensitive as nucleic acid, it can be detected by most patients when the virus concentration is relatively high.

Experts say that antigen detection is fast and convenient. The sooner an infected person is found, the less the virus will spread, and the faster we can take prevention and control measures, and finally we can achieve "dynamic zero clearing" at a faster speed.

Yesterday, National Medical Products Administration approved the registration applications of five COVID-19 antigen products. Since then, a total of 10 COVID-19 antigen self-test products have been officially listed. The self-test of antigen needs to read the instructions carefully, and carry out sampling, sample addition and result interpretation in accordance with the specified requirements and procedures.

Li Jinming, Deputy Director of Clinical Laboratory Center of National Health and Wellness Commission:Self-test is generally to take nasal swab, and the general temperature is room temperature. Let’s do the test below, not too cold or too hot.

Persons with positive antigen self-test, regardless of whether they have symptoms such as respiratory tract and fever, should immediately report to their communities (villages and towns), and the communities (villages and towns) should contact the emergency center to transport residents to medical institutions with fever clinics for nucleic acid detection in accordance with the guidelines for the transport of personnel related to the COVID-19 epidemic. At the same time, the sampling swabs, sampling tubes and test cards used by positive personnel are put into sealed bags and transported to medical institutions for medical waste disposal.

People with negative antigen self-test but symptoms are advised to go to a medical institution with fever clinic as soon as possible for nucleic acid detection; If it is inconvenient to see a doctor, you should isolate yourself at home, avoid going out for activities, and conduct antigen self-test once a day for 5 consecutive days.

Ministry of Industry and Information Technology: The "Thirteenth Five-Year Plan" will accelerate the application capability of big data industry

  Xinhua News Agency, Beijing, January 31 (Reporter Zhang Xinxin) The Ministry of Industry and Information Technology recently issued the "Big Data Industry Development Plan (2016-2020)", specifically proposing to accelerate the application capacity of the big data industry. By 2020, the revenue of big data-related products and services will exceed 1 trillion yuan, and the compound annual growth rate will remain around 30%.

  With the advancement of informatization, data has become an important resource. At present, big data is widely used in life. For example, map software uses it to measure congested road sections to prompt travel, and shopping software uses it to analyze consumers’ preferences for precise marketing. In the field of home care, children’s smart watches with safe positioning and other functions are also popular in the market. In 2016, the total annual sales of 360 children’s watches reached 1.82 million units. Up to now, the total mileage of guarding children has reached 2.38 billion kilometers.

  However, in industrial production, especially in promoting intelligent manufacturing and industrial transformation and upgrading, the application capability of big data needs to be improved. For example, accurately sensing user needs through big data to improve R&D efficiency; Use big data monitoring to optimize assembly line operation and strengthen fault prediction and management; Use big data to improve management efficiency and decision-making level, and realize the intelligence of business activities.

  Some big data companies have tried first and laid out their industrial applications. Inspur Group launched its big data market last year. At present, Inspur Enterprise Big Data has been applied to China Grain Storage, China Energy Conservation and other enterprises to provide accurate data analysis and management. Among them, Inspur built a big data platform for intelligent grain depots for China Grain Storage, and realized intelligent warehousing and decision-making.

  According to the Ministry of Industry and Information Technology, in the future, big data will be applied in the whole process of industrial production. On the one hand, it will greatly improve the efficiency of internal operation and management of enterprises; on the other hand, it will develop personalized customization based on big data to enhance the intelligence and flexibility of manufacturing processes.

  The Ministry of Industry and Information Technology will also build a "double innovation" platform for big data of manufacturing enterprises to cultivate new technologies, new formats and new models. In particular, it is necessary to use big data to promote the transformation, upgrading and development of small and medium-sized enterprises.

Looking at consumption in the New Year | hua county, Henan: Innovation in the inheritance of golden fried cakes and special foods

CCTV News:During the New Year, local cuisines have their own unique skills. In hua county, Anyang, Henan, fried shredded cakes are one of the patterns, which are deeply loved by local people.

Stir-fried shredded cake is a "combination of vegetables and rice" home-cooked meal. According to legend, in the early Southern Song Dynasty, a family named Yang set up a restaurant named "Yangjia Restaurant" in the sand shop next to Guandao Road. The restaurant was characterized by baking dough embryos into cakes. When diners ate, they cut the pancakes into shredded cakes and carefully fried them with the original "three wet and three dry eggs" method, so it was favored by diners from south to north. Nowadays, Yang Hongyan, the ninth generation descendant of Yangjiaguan fried cake silk, has been inheriting it for 30 years.

Yang Hongyan, the ninth generation descendant of fried cakes in Yangjia Restaurant, Shanan Village, Wangzhuang Town, hua county City, Anyang, Henan Province;Our own baked cakes are delicious, delicious and gluten-rich, and the fried cakes are good in color and taste like wheat.

Skilled knife workers, the flour cake is quickly cut into shredded cakes with consistent length and uniform thickness, and then the oil is poured into the shredded cakes in a warm pot and stir-fried until the oil is completely immersed in the shredded cakes. After that, the oil is burned again, the oil-soaked cake shreds are put into the pot for the second time, and the evenly stirred egg liquid is poured into the pan to stir fry.

Yang Hongyan, the ninth generation descendant of fried cakes in Yangjia Restaurant, Shanan Village, Wangzhuang Town, hua county City, Anyang, Henan Province;The key to frying shredded cakes lies in frying. Mastering the heat depends on understanding. If the oil temperature is too high, the paste will grow inside, and if the oil temperature is too low, the cake will not smell.

Finally, add vegetables and green onions into the fried shredded cake, and cover the pot to stew the cake. In ten minutes, the fried shredded cake is soft and delicious, fragrant but not greasy, and it is memorable to eat.

Last year, China’s cross-border e-commerce exports increased by 11.7%-broadening the "Made in China" sea passage.

According to a report released by the Ministry of Commerce not long ago, the import and export volume of cross-border e-commerce (including B2B) in 2022 was 2.11 trillion yuan, up 9.8% year-on-year. Among them, exports amounted to 1.55 trillion yuan, up 11.7% year-on-year.

In the interview, the reporter found that more and more China manufacturing enterprises rely on cross-border e-commerce to export their products. Especially since 2023, a series of support policies have been intensively introduced, such as improving customs clearance efficiency, cultivating and expanding overseas warehouses, reducing the export return cost of cross-border e-commerce enterprises, improving the logistics infrastructure for cross-border e-commerce development, and promoting the development of cross-border e-commerce comprehensive experimental zone with high quality, which further boosted the confidence of relevant enterprises to sail to sea.

Policies are strong, and export channels are smoother.

"When I first saw these rice noodles, I wanted to try them. It doesn’t take much time to brew, and the ingredients are sufficient. I will buy it again next time! " On the message board of Yami.com, American consumer Kimluu praised the bagged snail powder bought online.

Yao Hanlin, chairman of Guangxi Luobawang Food Technology Co., Ltd. told this reporter that in 2022, the export value of bagged snail powder reached 45.57 million yuan, a year-on-year increase of 27% from January to February this year. According to data from overseas e-commerce platforms, the proportion of non-Chinese consumers with bagged snail powder has increased from less than 1% at first to about 15%.

"Take the American market as an example. At present, Snail Overlord has completed the construction of overseas warehouses of the Los Angeles brand, and will also complete the construction of overseas warehouses in new york in the first half of this year. We hope to further shorten the transportation time and deliver the products to overseas consumers faster. " Yao Hanlin said that this year’s cross-border e-commerce is the top priority for Snail Overlord to explore overseas markets. The local government departments in Liuzhou are continuing to help enterprises solve various problems encountered in cross-border e-commerce business and promote smoother export channels for enterprises.

Snail powder has crossed the ocean, which is a microcosm of "Made in China" going out to sea through cross-border e-commerce. Since the beginning of this year, policy support measures have continued:

The Ministry of Finance and other three departments issued a tax policy for goods returned by cross-border e-commerce, and proposed to exempt goods that meet the relevant conditions from import duties, import value-added tax and consumption tax, so as to reduce the export return cost of cross-border e-commerce enterprises and actively support the development of new foreign trade formats.

In the "Implementation Opinions on Accelerating the High-quality Development of cross-border electronic commerce", Hangzhou, Zhejiang Province proposed that enterprises that carry out cross-border e-commerce export business through customs supervision modes such as cross-border trade e-commerce, cross-border e-commerce B2B (business-to-business) direct export, and cross-border e-commerce export overseas warehouses should be given no more than 2 million yuan in financial support every year.

In the "Three-year Action Plan for Promoting the High-quality Development of Cross-border E-commerce in Chengdu (2023-2025)", Chengdu, Sichuan explicitly encourages innovative, green and high value-added products to realize the integration of trade in goods and productive services by cross-border e-commerce, and promotes the upgrading of industrial chain through "cooperative research and development, customized production, product export and after-sales maintenance" and accelerates the transformation from "quality production" to "brand building".

Xie Juanjuan, a professor at the School of Economics of Nankai University, said in an interview with this reporter that at present, the risk of global economic recession is rising, the growth of external demand continues to slow down, and the steady growth of foreign trade is under great pressure. At this time, cross-border e-commerce has become the new engine of foreign trade development, especially manufacturing export, with the characteristics of new model, quick response and low cost.

"There are many kinds of manufacturing products, and the performance characteristics and sales methods of different products are also very different. Cross-border e-commerce can provide a unique way of exhibition and communication for manufacturing enterprises, and broaden the access of’ Made in China’ to the global market. At this time, the relevant departments provide support from financing, law, finance and taxation, which is not only conducive to standardizing and guiding the development of cross-border e-commerce, but also helps’ Made in China’ to reach downstream enterprises and consumers around the world more quickly. " Xie Juanjuan said.

Enterprises exert their strength, "the wine is not deep in the alley"

High-tech, high value-added "Made in China" has become a new growth point for export, which is behind the improvement of the quality of enterprise development.

Product practice "internal strength"-

Laser cutting has the characteristics of high precision, fast cutting and low processing cost, and is widely used in the field of metal processing. Beginning in 2018, with the improvement of the localization level of the core component of the laser, new business opportunities began to emerge.

"After the localization of the laser, a million-dollar laser cutting machine can be reduced to two or three hundred thousand yuan." Ma Tongwei, general manager of Shandong Ruitu Laser Technology Co., Ltd., noticed that the reduction of the cost of domestic laser cutting machines opened the "blue ocean" of the export market. "Main attack laser cutting machine export!" Ma Tongwei made up his mind.

However, it is not easy for small and micro enterprises to gain the trust of overseas customers. "Through Alibaba International Station, we send product parameters and operation videos to overseas customers. After they place an order, the funds will be frozen by the platform. After the customer receives the goods and passes the acceptance, the payment will be sent to us." Ma Tongwei told this reporter that with the early layout of cross-border e-commerce, the export growth rate of Ruitu Laser has remained at about 30% in recent years.

"Now, our products are exported to the United States, France, Russia, Turkey, South Korea and other places, and overseas customers have higher and higher expectations for Ruitu laser. Recently, we are making every effort to increase the cutting thickness of steel plates from 30 mm to 50 mm, and at the same time explore the supporting services of automated production lines. " He said.

Sales repair "external work"-

Excavators, loaders, road rollers, bulldozers … With the improvement of manufacturing level in China, more and more construction machinery products are going abroad at an accelerated pace. "In 2022, our overseas sales revenue reached a record high, with a year-on-year increase of nearly 60%. In January this year, overseas sales revenue increased by over 90% year-on-year. " Wang Chuanming, Chairman of SINOMACH International Equipment Co., Ltd. said.

According to Wang Chuanming, SINOMACH has not only more than 100 overseas agents, but also dispatched engineers to major markets around the world to provide thoughtful after-sales service. Affected by the epidemic, SINOMACH has made many innovative attempts in the field of "offline capability online" in recent years, and cross-border e-commerce is an important force.

"On the one hand, we actively use online training, VR exhibition halls, live inspection and other means to enrich the online negotiation experience; On the other hand, we take the initiative to collect the inquiry data of all trading platforms. The whole link process management covers the progress of negotiation, fund management, production delivery process, etc., which effectively improves the business transformation ability of cross-border e-commerce. " He said that at present, enterprises are actively promoting the construction of e-commerce teams.

Cross-border e-commerce has also enabled manufacturing companies to meet more long-term partners.

Changsha Hangshen Intelligent Technology Co., Ltd., as a leading L4 unmanned core technology provider and intelligent logistics product provider, produces unmanned vehicles that can be widely used in goods transportation, commodity sales, environmental disinfection and other fields. In recent years, with the help of the cross-border e-commerce platform provided by JD.COM, the "Chaoying" series unmanned vehicles produced by enterprises have successfully entered the Japanese market, providing food delivery service for outdoor camping customers of Polygonum cuspidatum Holiday City.

"Good wine, alley can’t deep. It is through cross-border e-commerce that this export is realized. Lotte Corporation of Japan has a strong interest in our products and hopes to carry out in-depth cooperation with us. " An Xiangjing, CEO of Hangshen Intelligent, told this reporter.

Market wrestling, matchmaking and confidence

The favor of the manufacturing industry has also promoted the development of the cross-border e-commerce industry itself. According to the latest data from the Ministry of Commerce, by the end of 2022, the State Council has set up 165 cross-border electronic commerce Comprehensive Experimental Zones in seven batches, covering 31 provinces, autonomous regions and municipalities. At present, there are about 200,000 cross-border e-commerce related enterprises in each comprehensive test area, of which more than 9,300 are recognized as high-tech enterprises.

Some keep an eye on market dynamics-

"In the past two years, more and more small and medium-sized enterprises have settled in overseas e-commerce platforms such as Amazon, Wayfair and Lazada. Keeping up with the needs of these enterprises, our business has also achieved rapid development. " Chen Zhongyu, general manager of Ningbo Ninghuatong International Trading Co., Ltd. said.

For small and medium-sized manufacturing enterprises, although cross-border e-commerce has brought a broader overseas market, it also means more complicated circulation links and a longer capital turnover period. Aiming at this market demand, Ninghuatong actively provides one-stop comprehensive foreign trade services such as commodity inspection, customs declaration, logistics, tax refund, foreign exchange settlement, credit insurance and financing for small and medium-sized cross-border e-commerce enterprises.

Chen Zhongyu told this reporter that since the beginning of this year, the Ministry of Finance, the General Administration of Customs and other departments have introduced new policies to reduce the export and return costs of cross-border e-commerce enterprises, and the business department of Haishu District of Ningbo City has also taken the initiative to answer questions from enterprises. These in-place policy supports have made enterprises feel warm. "We have confidence in connecting small and medium-sized enterprises to the sea!"

Some innovative service forms-

According to the data of Alibaba International Station, in cross-border e-commerce, real-time reception by real people can increase the conversion rate of potential customers of foreign trade enterprises by nearly 10 percentage points. According to Dai Xianwen, director of industry operation of Alibaba International Station, cross-border live broadcast and short video can help foreign trade enterprises display factories and production lines more intuitively and vividly. Especially in cross-border e-commerce B2B transactions, the live reception of foreign trade enterprises’ cross-border live broadcasts plays a key role in building buyers’ trust.

Dai Xianwen revealed that in the near future, the platform will help "Made in China" to export through the cross-border e-commerce platform through activities such as "New Trade Festival in March". "In March this year, we will pass on the new technologies, new technologies, new materials and new products of domestic manufacturing enterprises to overseas buyers through online exhibitions, online venues and live multimedia interactions. We will also actively use digital technology to analyze industry supply and demand, study industry strategies, and provide them to domestic manufacturing enterprises to help them better understand potential market opportunities. " Dai Xianwen said.

There are also enhanced technical support-

"Cross-border e-commerce should not only solve the problem of building a station, but also solve the logistics problem, and at the same time solve the problems of capital, transaction, delivery and delivery. In the market wrestling, cloud service providers need to provide sufficient technical support capabilities and ecological construction capabilities. " The relevant person in charge of Huawei Cloud told this reporter that Huawei Cloud is actively focusing on "information flow, capital flow and logistics" to open up the full link ecology for "Made in China".

According to the person in charge, Huawei Cloud has built a new computing architecture that is more suitable for the development of cross-border e-commerce through industry-leading technologies such as big data and artificial intelligence, providing one-stop simple, convenient, intelligent, efficient, safe and compliant products and services for cross-border e-commerce enterprises. Related technologies can help users rapidly expand their global business in all aspects, such as site decoration, commodity management, content review, order management, cross-border payment, and logistics inquiry.

The Ministry of Commerce said that this year, it is necessary to promote the sustained, rapid and healthy development of new formats such as cross-border e-commerce and overseas warehouses, make full use of digital means to tap the trade potential, and drive small and medium-sized micro-foreign trade enterprises to export.

Jewelry also opens a "beauty" concealer? Online shopping jewelry with scratches in consumer live broadcast room

  I bought colorful pendants in the live broadcast room, but found flaws and scratches after receiving the goods. The consumer applied for a refund of the goods at the first time, but was sued by the merchant to the court. Recently, the Beijing Internet Court concluded a case in which a merchant v. Mr. Wang and the e-commerce platform information network sales contract dispute, and finally decided that the merchant lost the case. The judge reminded consumers that when ordering valuables in the live broadcast room, they should have a sense of screening and deposit certificates, and don’t get lost in various "beauty filters".

  Data map jewelry e-commerce live broadcast (Source: Southern Network)

  The plaintiff’s company opened a live broadcast room on an e-commerce platform to sell colorful pendants, and the live broadcast pictures and playback pictures showed that the pendants were intact and flawless. In February 2021, Mr. Wang, a consumer, placed an order to buy a pendant after watching the live broadcast, and paid 50,000 yuan. After receiving the goods, Mr. Wang found that a sapphire on the pendant had scratches, and immediately initiated a refund on the platform, and the platform immediately frozen the payment.

  The plaintiff’s company believes that before the delivery of the goods, the details of the goods have been fully displayed to the defendant Mr. Wang through videos and pictures, and there are no cracks or flaws. Therefore, the plaintiff believes that the goods are qualified goods and there is no breach of contract, so he appealed to the court and requested that the defendant Mr. Wang and the e-commerce platform perform the contract and pay the purchase price.

  The defendant, Mr. Wang, argued that there was no crack in the live video because there was a filter in the live video and the crack needed to be enlarged to see clearly. Mr. Wang said that he found the goods defective after receiving the goods, and he sent the photos of the pendants he received to the plaintiff in the first time according to the normal process, and marked them with scratches. The plaintiff failed to deliver the goods as agreed in the contract, and requested the court to reject all the plaintiff’s claims according to law.

  The Beijing Internet Court held that the defendant, Mr. Wang, bought the pendant involved in the case in an online shop of the plaintiff’s company and paid for it. All parties recognized that there was a sales contract relationship, which meant that it was true, legal and valid. Therefore, the online shopping contract relationship between the two parties was established and should be performed according to the contract. Although neither the live video of the pendant involved nor the video sent by the plaintiff to the defendant can see that there are cracks on the gem of the pendant involved, the video shows the pendant in a normal picture and has not been enlarged. The gem with cracks in this case is small in size, with a diameter of only 5 mm. It cannot be ruled out that cracks cannot be seen in live broadcast and video due to angle and screen size problems. After enlarging the photo of the pendant submitted by the defendant Mr. Wang, it can be seen that there is indeed a crack in one of the sapphires.

  To sum up, the defendant Mr. Wang has paid the corresponding payment for the relevant order (the payment has been frozen by the platform due to disputes between the two parties), but the plaintiff’s company failed to deliver the goods as agreed. Therefore, in the case that the plaintiff failed to deliver the agreed goods and there was a dispute between the buyer and the seller, the court refused to support the plaintiff’s claim for the defendant to pay for the goods, and decided to reject all the claims of the plaintiff’s company. At present, the judgment of this case has come into effect.

  The presiding judge of this case said that online shopping is different from the traditional shopping mode in terms of transaction subject identification, contract conclusion, commodity delivery, price delivery, after-sales service and dispute resolution. In recent years, there has been a wave of jewelry and jade articles in live shopping. Consumers should have a sense of identification and deposit certificates when they watch online live orders for valuables. Before buying, they should carefully ask about the details of the goods, such as pre-sales quality assurance, after-sales guarantee, conditions and scope of returning and exchanging goods, and keep live video, playback and chat records in time. Once there is a problem with the goods, consumers should communicate with the store sellers at the first time and negotiate the after-sales treatment. If it cannot be resolved, both parties can apply for platform intervention or seek the help of market supervision departments and consumer protection committees, and if necessary, they can safeguard their legitimate rights and interests through judicial means.

Is it risky to scan QR code?

  With the popularity of smart phones and mobile networking, mobile phone scanning QR code has become a common scene in life, such as scanning code payment, adding friends to each other and so on. QR codes are basically everywhere in our lives, so is it risky to scan QR codes? Below, Xiaobian will introduce them to you.

   

Is it risky to scan QR code?

  1. Firstly, the essence of two-dimensional code is to record data and symbol information by black-and-white graphics distributed in a plane (two-dimensional direction) according to a certain law, and use several geometric shapes corresponding to binary to represent literal numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment to realize automatic information processing:

  2. It is risky to scan the QR code, because the essence of the QR code shared now is a string of digital codes or a link to a website.

Intelligent assisted driving racing and dark warfare

The wave of intelligence is sweeping the world and profoundly reshaping the transportation field. Chip, lidar, AI algorithm, vehicle-road coordination and other related technologies are rapidly iterated, and scenes such as unmanned taxis and unmanned distribution are gradually landing, pushing the commercialization of intelligent assisted driving into a critical period.

In 2025, the intelligent assisted driving track is no longer just a contest of parameters, but also a race and a dark battle-when the market value list of car companies forms a fault stratification, when the full-stack self-research group and the open cooperation camp are arguing endlessly, when the price of laser radar is halved, when domestic chips are accelerated to replace, everyone wants to "squeeze on the train", who can stay?

The Beijing News reporter initially sorted out that there are at least 300 listed companies involved in intelligent assisted driving business in China, covering the A-share, Hong Kong-share and US-share markets. According to comprehensive data and research reports, there are thousands of companies in the field of intelligent assisted driving in China.

Based on this, according to the public data and corporate information, the Beijing News reporter made an inventory of the functional level of the assisted driving industry, the market value of listed companies, and the number of cooperative customers. Among the A-share listed companies involved in intelligent assisted driving, BYD is the trillion-dollar leader with the highest market value and the highest sales volume of new energy vehicles, Huawei, BYD, Tucki, etc. rank first in the intelligent assisted driving function, and the number of customers of cooperative car enterprises is ahead by Mom en ta.

Market value competition trillion bibcock and chaser

According to the ranking of the total market value as of May 14, 2025, the top five companies involved in the concept of intelligent assisted driving and the total market value in A shares are BYD, Cyrus, SAIC, Great Wall Motor and Zhongji Xuchuang.

BYD ranks first among A-share intelligent assisted driving companies with a market value of 1.11 trillion yuan. The competition of the second echelon is even more intense. The market value gap between Celestial (213.4 billion yuan), SAIC (192.2 billion yuan) and Great Wall Motor (172.9 billion yuan) is only in the order of billions. In the US stock market, the market value performance of Tucki, Ideals and other new forces is also neck and neck.

Some enterprises related to the industrial chain told the Beijing News reporter that now the automobile factory directly faces the terminal market, which has gained higher attention and higher voice and pricing power. Although technology suppliers are more professional on the technology track, their right to speak is relatively low. As far as the capital market is concerned, it will also favor the automobile factory with larger volume, more brand effect and more "storytelling". This is reflected in the market value. In the Hong Kong stock market, the market value of supply chain enterprises such as Horizon and Black Sesame Intelligence is less than HK$ 100 billion.

Sales volume comparison

Technology Pratt & Whitney and Brand Premium

Further according to the sales comparison, BYD’s sales of new energy vehicles are riding a dust. In 2024, BYD’s global sales of new energy vehicles reached 4.272 million, up 41.26% year-on-year, becoming the global sales champion of new energy vehicles, and its huge sales provided a data foundation for its assisted driving development.

BYD’s competitors are not only domestic car companies, but also compete with Tesla as representatives of China car companies.

While BYD’s sales in 2024 surpassed Tesla’s, the competitive logic behind the two is completely different. Byd relies on the large-scale strategy of "smart driving and equal rights" to sink the intelligent assisted driving technology to the 70,000-yuan market, while Tesla relies on the FSD technology premium to maintain the mid-to high-end positioning. Behind this market value competition are two routes: people-friendly and brand premium.

Battle of ecology

Full-stack self-research and open cooperation

At present, the intelligent assisted driving technology has entered a period of rapid development, and various enterprises have launched differentiated solutions through self-research or cooperation to promote the popularization of functions and upgrade the experience.

Among car companies, BYD and Tucki are both representatives of self-research of car companies, and they also belong to the first echelon. For example, BYD’s self-developed high-order intelligent assistant system is called "Eye of the God". Tucki, Ideal and other car companies are also constantly exerting their efforts in assisting driving.

Some companies do not fully agree with the self-research model of car companies. Wu Yongqiao, president of Bosch Intelligent Driving Control System in China, has publicly stated that in the future, intermediate intelligent assisted driving will become the standard, and the main engine factory will invest hundreds of millions or even billions of dollars in full-stack self-research every year, which is costly and not cost-effective, and should be handed over to the supply chain for processing.

Huawei has always been listed as the first echelon of intelligent assisted driving system. Jin Yuzhi, CEO of BU, Huawei’s smart car solution, said in 2024 that 10 brands of 7 car companies will adopt Gankun solutions, including Chang ‘an Deep Blue, Celestial, etc. It is estimated that there will be more than 500,000 cars driven by Huawei.

In contrast to self-research, Huawei’s "friend circle" model shows another possibility. At present, Huawei has three modes for automobile business, namely, parts supply mode, H I(Huawei Inside) mode and intelligent car selection mode.

Providing spare parts to BMW, BYD and other car companies, referred to as "spare parts supply model". Relying on Huawei’s intelligent solution cooperation, such as Beiqi Extreme Fox and Aouita, referred to as HI mode. Car companies have deep cooperation with Huawei, and Huawei participates in product design, marketing and sales. These models will appear in the Huawei Experience Center, and the intellectual and intellectual circles belong to this kind of cooperation, referred to as the smart car selection model. Among the above three modes, the one with the closest cooperation depth is the smart car selection mode.

SAIC has publicly stated that "the soul should be in its own hands", and now it also chooses to cooperate with Huawei. While Huawei’s partners get the benefits brought by the sales growth of cooperative models, they also need to face the question of "whether the car companies themselves have mastered the core technology", such as whether Cyrus and Jianghuai can independently build high-quality models of their own brands.

More noteworthy is the rise of the middle route. Technology suppliers such as self-driving unicorn M omenta (Beijing Chusu Technology Co., Ltd.) and Baidu Apol?lo are exploring their own unique routes.

Mass production and large-scale application are the key words of M omenta. On May 12th this year, Xiangdao Travel signed a strategic cooperation agreement with Momenta, and the two sides will jointly build the world’s first robotaxi (self-driving taxi) fleet based on the pre-installed mass production scheme, and take the lead in starting operation in Shanghai, which will become a robotaxi fleet that is "born for large-scale application in cities".

Baidu radish run is aimed at overseas. On March 28 this year, Baidu Radish Run announced the signing of a strategic cooperation agreement with Dubai Road Transportation Bureau, and plans to deploy more than 1,000 fully driverless cars in Dubai. This is also the first time that Radish Run has carried out unmanned large-scale testing and service outside China.

The transformation and reconstruction of industrial chain

When the intelligent assisted driving function changed from "high-end label" to "basic configuration", a reshuffle sweeping the entire industrial chain has already started.

The Beijing News reporter combed and found that the competition in the number of customers of assisted driving supply chain enterprises is characterized by wide coverage, large number of cooperation and diversified customer types. All enterprises are striving to expand their customer base in order to gain an advantage in the fierce market competition.

Among them, Momenta is the company with the widest coverage of cooperative car companies, which covers 7 of the top 10 car companies in the world and has more than 130 cooperative mass production models.

In the field of lidar, the two "leading players" are deadlocked and the competition is extremely fierce. Sagitar Juchuang cooperates with 92 models of 28 automakers and first-class suppliers. Hesai Technology cooperated with 120 models of 22 car companies, and won big orders simultaneously under the price reduction strategy.

In an interview with the media in November, 2024, Li Yifan, the founder of Hesai Technology, publicly stated that the company planned to reduce the price of its main lidar products by half to US$ 200 in 2025, which means that electric vehicles with a price less than 150,000 yuan can also use lidar. On February 11, 2025, Hesai Technology announced that various models of BYD will be equipped with Hesai’s lidar products, and it is planned to achieve mass production delivery in 2025.

These news not only show the "involution" of lidar track, but also reflect the bargaining power of car companies. Shen Ziyu, co-founder and chairman of Yikatong Technology, publicly stated in March 2024 that "there will be no laser radar companies and millimeter wave radar companies in the future, only incremental component companies for smart electric vehicles."

The competition on the chip track is even more cruel. Horizon used 9 years to load more than 4 million Journey series chips, which replaced M obileye in L2 market. Under the reality that NVIDIA O rin chips still dominate the high-end market, domestic chip companies still have a long way to go.

In addition to hardware iteration, the battle for software route is equally fierce. At present, the "map-free" route led by Tesla is in fierce confrontation with the "high-precision map" faction adhered to by NavInfo.

Behind the multi-faceted competition, enterprises are also facing common challenges. In the field of intelligent assisted driving, L3 and above autonomous driving technology has not been allowed to go on the road, and no more detailed regulations and regulations concerning the definition of responsibilities and road regulations have been issued at the national level. The commercialization of intelligent driving technology still faces uncertainty.

In addition, whether it is the full-stack self-research of automobile enterprises or the research and development of industrial chain enterprises, from chips, algorithms to system integration, every link needs a lot of financial support. In the future, the investment of tens of billions will continue to raise the threshold of intelligent assisted driving.

Despite this, the panorama of China’s spiraling intelligent assisted driving industry has also begun. BYD’s "intellectual drive and equal rights" have brought assisted driving into thousands of households, and Huawei’s "multi-party cooperation" has continuously broadened the boundaries. The rise of Hesai Technology and Horizon proves that there are no eternal giants in the trillion-dollar market.

How to balance the technical innovation and safety bottom line of assisted driving of the circle round table school?

Since April this year, the Ministry of Industry and Information Technology has carried out strong supervision on the promotion of intelligent networked vehicles, requiring automobile companies to fully carry out the combined driving assistance test and verification, clarify the functional boundaries and safety response measures of the system, and refrain from exaggerating and false propaganda. China Automobile Industry Association and China Automotive Engineering Society also issued a proposal to standardize the promotion and application of driver assistance. For a time, car companies have renamed the sayings of automatic driving, autonomous driving, intelligent driving and high-order intelligent driving as assisted driving.

With stricter supervision, how to balance technology popularization and safety in assisted driving? How to establish a database of assisted driving accidents for cross-vehicle enterprises? The Beijing News reporter invited nine guests, including enterprises and experts, to participate in the "Circle Roundtable School" on topics related to assisted driving development.

Popularizing assisted driving requires safety as the premise.

Beijing News: How to balance the popularization and safety of assisted driving technology?

Lu Fang: First of all, the popularization of assisted driving technology should follow the gradual development path, and each stage should be fully verified to ensure reliability, so as to avoid premature pursuit of "completely unmanned" and ignoring potential risks. At the same time, key systems (such as perception, decision-making and execution) should be designed with multi-sensor fusion, algorithm redundancy and hardware backup, and data should be accumulated through massive virtual simulation tests (covering extreme scenes) and real road tests to optimize the algorithm’s ability to cope with complex scenes. Only when the technology is mature can security be guaranteed.

In addition, when promoting assisted driving technology, we must talk about equal rights and take safety as the basis, so that users can clearly know what the capability boundary of each car technology is. The ultimate goal of assisted driving is to improve users’ travel safety. Enterprises should take "safety first" rather than "speed first" as the principle, and the public should rationally look at the potential and limitations of technology.

Wu Huixiao: Great Wall Motor has always stressed that assisted driving is still in the primary development stage at this stage, and there is still a long way to go before real automatic driving. The core value of assisted driving is to improve travel safety and efficiency, not marketing gimmicks. In addition, we suggest establishing a national public test database for intelligent driving, sharing desensitization accident data, and accelerating the establishment and iteration of safety standards for intelligent driving.

In product communication, enterprises should face up to the development stage of technology, respect its development law, and truly inform users of the availability and applicability of technology, so as to avoid the risk of misuse caused by exaggerated publicity and even affect the overall cognition of China automobile industry.

Wang Haowei: The smarter the algorithm, the greater the security challenge; On the contrary, the safest algorithm is the simplest logic. Therefore, the core issue of the popularization of assisted driving is to find a balance between intelligence and safety. Absolute security can’t be achieved. What’s more important is to let the end users know the capability boundary of the system, instead of relying too much on the system capability. Safety is a comprehensive project, and there is no once-and-for-all approach. Efforts should be made from system design, algorithm, security mechanism, user training, regulations and new technologies.

Zheng Zhuangcheng: The popularity and safety of assisted driving are not antagonistic, but "two sides of one body" that need to be promoted together. Balancing the two needs to be realized from several dimensions: first, technical iteration is carried out with ensuring safety as the lowest level of assisted driving requirements; The second is to establish an industry safety baseline; The third is user education, which pays equal attention to popularization and transparency; The fourth is ecological synergy, and the responsibility of the whole industry chain is shared.

Dai Yifan: The essence of assisted driving application is to improve safety. It is meaningless to talk about popularizing assisted driving system without safety guarantee. Therefore, there is a "priority weight" relationship between the two, and it must be on the premise of ensuring safety and improving the existing driving safety before promoting the assisted driving system.

Need to break the "absolute trust" in assisted driving

Beijing News: In view of the public’s "absolute trust" in assisted driving, how to rebuild a transparent communication mechanism?

Wang Haowei: Absolute trust is a dangerous term, because there is no absolutely safe system. The relative trust of the public in assisted driving is what the industry needs to pursue. Relative trust means with boundaries and conditions, and it also means that we must pursue the best under certain conditions, not the global optimal solution.

Zheng Zhuangcheng: Transparency is a technical safety belt in the era of assisted driving. NavInfo rebuilds public trust based on three core measures: technical transparency, real-time update and "data security is the cornerstone of building smart driving security".

Dai Yifan: At present, assisted driving requires drivers to stay in the loop and stay awake, especially in some abnormal road scenes. Assisted driving requires popular science rather than hype. The so-called "assistance" means helping drivers, and there must be some guidance in propaganda.

Zhuang Jinggan: Many people think that the "smart driving" system is safe and reliable enough, but this is not the case. This misunderstanding largely comes from the early propaganda strategy of car companies, which makes consumers mistakenly think that technology is mature enough to replace human driving, ignoring the capability boundary and potential risks of the system.

The database of assisted driving accidents suggests that the government should take the lead.

Beijing News: It is suggested that a database of assisted driving accidents across car companies can be established to provide a technical basis for the determination of responsibility. What do you think?

Wang Haowei: To establish a database of assisted driving accidents of cross-vehicle enterprises, it is necessary to introduce relevant data uploading standards at the national level, and it is best to enforce them.

At the same time, the balance between the bottom line of safety and the development of the industry should be taken into account in the determination of responsibility. If all the responsibilities are put on car companies, it will lead to the lack of awe of the public in using the assisted driving function, which will eventually inhibit the motivation of car companies to develop assisted driving.

Zhuang Jinggan: "Government-led, joint car companies to build a unified national database" is helpful to standardize industry practice. At present, there are great differences in technical routes and data formats among car companies. If they are independent, they will form "data islands", which cannot support the general standards of the industry. The government can take the lead in formulating data collection standards, and car companies can access key information such as operation logs, sensor data and system decision records, and establish a privacy protection mechanism to desensitize sensitive information.

After the completion of the database, it is necessary to clarify the framework of responsibility division, and it is suggested that the legislature should formulate special laws, and at the same time clarify the criteria for identifying technical defects and dynamically divide the proportion of man-machine responsibility. In addition, we can also consider establishing a "data black box" system and handing over the right of data analysis to a third-party authority.

Auxiliary driving will develop in the direction of equal rights.

Beijing News: Do you think the development of L3 or L4 autopilot will be hindered? What is the trend of assisted driving?

Lu Fang: The development of L3 or L4 may be hindered, but the overall trend is still forward. Although the existing technology has covered most conventional scenes, some extreme scenes (such as rainstorm, blurred road markings and sudden obstacles) are still the core obstacles for L3 and L4 to land. Coupled with the public’s lack of awareness of autonomous driving technology, the wide application of L3 and L4 technologies is limited to some extent.

However, at present, the industry has L3-level technical reserves, and the Ministry of Industry and Information Technology is also accelerating the improvement of the automatic driving standard system, promoting the safety baseline construction, and the industrial chain is also upgrading in coordination. These are all positive aspects.

Deng Chenghao: The current policy’s regulation of L2 function is essentially an "ice-breaking action" to pave the way for advanced autonomous driving. This will not hinder the development of L3/L4, but instead build three booster engines. The first is to establish the coordinate system of technological evolution. The latest national standard "Auto Driving Automation Classification" issued by the Ministry of Industry and Information Technology defines the responsibility dividing line (ODD operation design domain) between L2 and L3 for the first time, which will accelerate the shift of consumers’ cognition from "whether there is function" to "capability boundary" and clear the cognitive obstacles for the commercialization of L3/L4. The second is to open up the fast lane of technology verification, and the "car-road-cloud" three-dimensional verification system will shorten the technology maturity cycle by 30%. The third is to reconstruct the ecology of industrial cooperation, and institutional breakthroughs are more strategic than simple technical breakthroughs.

Zheng Zhuangcheng: From the perspective of four-dimensional map and safety redundancy, the future development trend of assisted driving will not be separated from the map. AI big model helps high-order intelligent driving to accelerate landing, but high-precision map is always an indispensable transcendental sensor to assist driving. The so-called "no map" will bring a series of problems such as increased cost and irregular data collection.

Zhang Ruixue: The large-scale landing of assisted driving mainly faces several problems: First, the perception and decision-making of complex scenes (such as non-signal scenes and complex environments) is still the core difficulty. The existing bicycle intelligence relies on multi-sensor fusion, but the hardware stack (such as laser radar) is expensive and cannot completely cover all long tail scenes. Second, the division of responsibility for autonomous driving accidents in the current law is not clear, and the insurance system also lacks an adaptation plan. Third, the data closed-loop ability is insufficient. High-order autopilot relies on the collection, labeling and model training of massive scene data, but the existing test area is limited in openness, resulting in insufficient data diversity.

Zhuang Jinggan: The landing of L3/L4 autopilot faces three core challenges: first, the long tail scene processing, that is, the reliability of the system is insufficient in extreme or rare scenes; Secondly, the law lags behind; Finally, the lack of infrastructure coordination, especially the slow progress of vehicle-road coordination (V2X). In the future, whether it is L2, L3 or L4 level assisted driving, it will develop in the direction of equal rights. This is mainly due to the rapid decline in the cost of the core components of assisted driving, and the technology is breaking through the high-priced barrier and moving towards large-scale application.

In 2019, the subsidy policy for new energy vehicles was released: the land compensation was cancelled, and the state compensation retreated.

(Observer News)

On the evening of 26th, the Ministry of Finance and other four departments jointly issued the Notice on Further Improving the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles. In 2019, the subsidy policy for new energy vehicles was officially released.

How does the subsidy "retreat"? First of all, local subsidies for new energy vehicles were cancelled this year; In terms of state subsidies, the plug-in hybrid subsidy is 10,000 yuan, and the subsidy for pure electric vehicles is 18,000 yuan for cruising range of 2.5-400km, and 25,000 yuan for those over 400 km.

In addition, for the transition period from March 26, 2019 to June 25, 2019, during the transition period, the licensed vehicles that meet the requirements of 2018 technical indicators but do not meet the requirements of 2019 technical indicators will be subsidized by 0.1 times of the corresponding standards last year, and the licensed vehicles that meet the requirements of 2019 technical indicators will be subsidized by 0.6 times of the corresponding standards last year. During the transition period, the fuel cell vehicles sold on the brand will be subsidized by 0.8 times of the corresponding standard in 2018.

In this regard, official website, the Ministry of Finance, issued a document explaining that although the scale of China’s new energy automobile industry is expanding rapidly, there are still problems such as "subsidy dependence", "insufficient local investment" and "local protection".Practice has proved that the dynamic adjustment mechanism of subsidy policy can actively promote China’s new energy automobile industry to become better, stronger and bigger, enhance its competitiveness and achieve high-quality industrial development.

The subsidy scheme for the promotion of new energy vehicles and the specific technical requirements of the products are as follows:
