Recently, "Jianbao Live Broadcasting" has attracted a lot of attention on the network platform. Although online treasure is popular, it also faces challenges such as professionalism, authenticity and supervision. How can Jianbao live broadcast stand the public’s "palm eyes"?

"Jianbao live broadcast" explosive network

Excessive entertainment affects the cognition of historical relics.

In the "Jianbao Live" program, fans will come up with strange items for the anchor to identify, and the anchors can’t satisfy the curiosity of some fans just by telling the truth and falsehood. In order to satisfy the curiosity of the audience, the anchor reveals the stories behind these items to increase the attraction of the live broadcast.

The reporter searched the social platform and found that many Jianbao live broadcast rooms were "Lianmai" in the form of video, and the details of the items were displayed with the anchor "Lianmai" and then identified by the anchor online.

A word from the anchor can determine the "fate" of an item, and the ups and downs of the "plot" naturally attract the attention of the audience. There are thousands of people online in some hot anchor live broadcast rooms, and many viewers interact with the anchor in the message area besides "Lianmai". The audience expected to get off-site judgment from the live broadcast, but ignored the authority of the anchor appraisal results.

Liu Qingzhu, a member of the Chinese Academy of Social Sciences and former director of the Institute of Archaeology, told reporters that most of the anchors broadcast live in the name of public welfare treasures, aiming at spreading the history and culture of cultural relics. However, excessive entertainment will make the real background of Jianbao live broadcast "taste".

"Appraisal is a scientific process. This view can only be the opinion of one family. Whether a consensus can be reached in the end still needs discussion and communication." Liu Qingzhu emphasized that if the identification process is turned into an activity that entertains the public and delights the eyes, there will be no necessary respect for real cultural relics.

Liu Qingzhu said that the live broadcast of Jianbao is inseparable from the active participation of the audience, and the head anchor has tens of millions of fans. Without correct value guidance, it is easy for the audience to have a negative perception of cultural relics.

Liu Qingzhu introduced that it is necessary to introduce to the public what Jianbao is, what disciplines Jianbao needs to intervene and how to identify it through TV and big data.

There are many words to sell "antique" scripts live.

Fraud gangs involved in fraud amounted to more than 20 million yuan.

In the live broadcast that only stays at the identification level, the audience may still be able to "watch the excitement". Once the so-called "cultural relics" are clearly priced and matched with various "routines" in the live broadcast room, the audience who "watch the excitement" may become "people in the game" unconsciously.

In January this year, Ms. Zhang (a pseudonym) from Xinxiang, Henan Province reported to the police that her mother had bought fake cultural relics in the webcast room, and she was convinced after repeated explanations.

"The first half of the live broadcast is usually some scripts. Several people stand in front of the camera and perform. My mother has been watching it until the anchor starts to have the intention to sell goods. I told her that these people are all selling goods." Ms. Zhang revealed that some dishes with carvings displayed in the live broadcast, similar to antique products, and jade pendants, are all made of plastic materials, "it is fake at a glance."

Ms. Zhang roughly calculated that there were hundreds of so-called "cultural relics" purchased by her mother, with a total value of more than 400,000 yuan. In desperation, Ms. Zhang went to the police station in the jurisdiction to report the police.

After being persuaded by the police, Ms. Zhang’s mother finally realized that she had been defrauded. Sun Zhenyu, the captain of the Criminal Investigation Brigade of Changyuan Public Security Bureau, said that according to the information provided by Ms. Zhang, the police found the live broadcast room involved and found that the anchor was broadcasting live in the same way.

After the suspects arrived at the case one after another, the police learned through trial that the internal division of labor of the criminal gang was very clear. There are special people in the gang who are responsible for writing scripts about parents’ short stories and trivial matters, and telling them to the audience through the anchor. When the audience slowly enters the plot, they sell goods for various reasons, and finally achieve the goal of earning money from the victims.

Miao Yusheng, a policeman from the first squadron of the Criminal Investigation Brigade of Changchun City Public Security Bureau, said that the gang had been involved in fraud for more than 20 million yuan in less than four months from October 2023 to February 2024.

Miao Yusheng said: "After investigation, it was found that the groups defrauded by the studio were all over 20 Yu Sheng and autonomous regions such as Henan, Hebei, Qinghai, Inner Mongolia, Xinjiang and Guangxi, with hundreds of victims."

At present, 27 suspects of the gang have all been arrested and brought to justice for alleged fraud.

Expert: Jianbao live broadcast should reflect professionalism and fairness.

Online "Jianbao" should also be standardized according to offline requirements.

In order to clarify the boundary with criminals, many live broadcast rooms of Jianbao anchors are marked with the word public welfare. Wu Zhenhua, deputy director of the Development Department of China Private Science and Technology Industrialists Association, said that public treasure collection can attract more audiences and help to understand the history and culture of cultural relics. Even for public welfare purposes, Jianbao live broadcast should maintain awe of history and respect for culture.

"Jianbao live broadcast can not identify the authenticity of items by video connection. This identification method is too simple and rough." Wu Zhenhua believes that the anchor’s identity, ability, experience and other aspects need the supervision of a third party organization, at least the audit of the live broadcast platform, not just a formality audit, but should be substantive.

Liu Qingzhu emphasized that the live broadcast of Jianbao should not only be an eye-catching entertainment, but also be a manifestation of professionalism and fairness. "The form of laughing and yelling in the webcast is easy to mobilize the emotions of young people. In fact, there is nothing wrong with the evaluation, and the hobby is good, but we should guide it well."

Liu Qingzhu said that in the current live broadcast of Jianbao, anchors often focus on telling stories, but some things are not stories, but history. "The story is just like telling a joke, and it is not serious in itself. Through the influence of the platform and the environment, the audience should gain knowledge and feel awe of history. "

Wu Zhenhua suggested that Jianbao is not a "new track", but just changed from offline to online, and online Jianbao should also be standardized according to offline requirements.

"In terms of publicity and popularization of cultural knowledge, in addition to traditional exhibitions, relevant museums can also conduct corresponding training, identification and qualification assessment for industry personnel currently engaged in Jianbao live broadcast, train and supervise anchors, and issue qualification certificates, thus establishing a set of institutional norms. At the same time, in this process, museums have to participate in Jianbao. We also need more standardized and correct guidance to support the development of the industry and popularize culture. " Wu Zhenhua said.

China Consumer News reports(ReporterWu BofengIn the midsummer, it is a common idea for many consumers to take their family on a weekend trip. And a mid-sized urban smart SUV may be able to meet your car needs.

In recent years, with the steady increase in the market share of new energy vehicles, the development advantages of BYD, which has been fully transformed into electrification, have become more and more obvious. Last year, BYD’s cumulative sales exceeded 3.02 million units for the first time in history, accounting for nearly 10% of the national annual car sales. On May 10, BYD launched a new medium-sized pure electric SUV, the Sea Lion 07EV, which benefited from the first model created by e-platform 3.0 Evo technology and the first model of the new Sea Lion IP of Ocean Network. It has attracted much attention since its launch. In the summer in Beijing, the in-depth contact with the Sea Lion 07EV is a good opportunity for reporters to have a deeper understanding of its product power.

Sea Lion 07EV appearance.Wu Bofeng/photo

Walking into the test drive venue and getting to know the vehicle at first glance, you can feel the distinct family style of the Sea Lion series. As a realistic interpretation of the Ocean X concept car, the front shape of the Sea Lion 07EV extracts the "X" shape from the dynamic perspective as the basic structure. Through the contrast of tone and material, the horizontal lines at the bottom are highlighted, which brings better visual extension to the whole front of the car, increases the overall visual width, and also makes the front profile of the Sea Lion 07EV appear more solid.

At a time when the phenomenon of product homogeneity is becoming more and more serious, how a new car can highlight its own characteristics and bring differentiation is an important prerequisite for being recognized by consumers. To this end, the two wheel hubs of the Sea Lion 07EV are inspired by the posture of the sea lion leaping into the water. Through pictographic treatment, the lines are simple and natural. At the same time, both wheels form a sharp tone contrast through color-painted brake calipers, strengthening the unique taste of the Sea Lion 07EV.

Sitting in the car, the interior style of the vehicle pursues individuality and practicality with the keywords of "suspension, lightweight and speed". Its internal lines continue the flow of the external design, and use a variety of materials to interpret various marine elements with delicate workmanship, bringing more active atmosphere to the elegant passenger cabin space.

This test drive route includes a variety of road conditions such as urban roads, urban expressways and expressways, which can accurately reflect the performance of the Sea Lion 07EV in various life scenarios. From the moment the reporter stepped on the accelerator, he felt the driving texture of the Sea Lion 07EV, which was neither slow nor aggressive, and the accelerator was just right. In addition, thanks to its 0-100km/h acceleration time of only 4.2 seconds, it can bring drivers a hearty power experience.

In the face of urban road sections, the Sea Lion 07EV can always feed back the power to you in time, helping you calmly complete actions such as overtaking and lane changing, without affecting the agility of the vehicle due to the body weight of the SUV. At the same time, the vehicle is very smooth in continuous power output, without making the driver and occupants feel uncomfortable and frustrated. Especially when driving on congested urban roads, this feature will make the driver more comfortable.

For a smart electric SUV, what are the substantive improvements that a new car equipped with a number of intelligent functions will bring? Within the range of high-speed and expressways covered by functions, the Sea Lion 07EV can follow the navigation and complete the task of automatic assisted driving from the starting point to the end point. During the test drive, the vehicle can follow the navigation route to complete operations such as automatic on-ramp, autonomous lane change or overtaking. In addition, the vehicle can intelligently adjust the vehicle speed according to the static and dynamic conditions of the road. When the reporter traveled to the West Fourth Ring Road area of Beijing, he encountered road construction. Seeing this, the vehicle’s high-speed pilot function initiated lane change in advance and actively avoided.

In order to further enhance the daily practicality and operation convenience of the smart driving function, the Sea Lion 07EV adopts a more concise and clear operation mode, and the different states of human-machine co-driving are intuitively presented on the instrument in the form of icons, which enhances the user’s driving perception and improves driving safety. The Sea Lion 07EV adopts the paddle start method pioneered by BYD in the world, and you can activate the driving auxiliary feature by raising your hand on the steering wheel, which is convenient and fast.

The reporter found through this test drive that the good product performance of the Sea Lion 07EV is no less than that of traditional fuel vehicle products of the same level, and a number of advanced technologies have been added to make the vehicle more competitive. It is believed that as more and more consumers understand the pure electric medium-sized SUV, this model is expected to be favored by more consumers.

　　Zhou Xingchi was pursued by his ex-girlfriend 57 million financial commission

　　A few days ago, Hong Kong media reported that Chow’s ex-girlfriend Yu Wenfeng to Chow and his subsidiary Xingyang overseas company to recover 70 million Hong Kong dollar sales commission, the case filed in the Hong Kong High Court.

　　Chow and Yu Wenfeng have been together for 13 years. During this period, Yu Wenfeng provided financial advisory services to Chow. The two parties reached an agreement in the name of the company. Chow Xingchi promised to pay Yu Wenfeng a monthly advisory fee of 20,000 to 59,000 Hong Kong dollars for the investment. Yu Wenfeng and Chow had a verbal agreement that if the investment made a profit, she would receive 10% of the profit. Chow Xingchi later invested in the development of a detached house on Poole Road on the Peak, which was valued at about 800 million Hong Kong dollars. Yu Wenfeng believes that she can get 80 million Hong Kong dollars commission. Chow Xingchi paid 10 million Hong Kong dollars in March this year, and the balance of HK $70 million is still outstanding. Chow later sent a letter through his lawyer saying that Yu Wenfeng had not paid the free gift of HK $10 million, and denied that it was in arrears with the sales commission.

　　Taiwanese actor Ethan Ethan was kicked by his ex-girlfriend

　　Ruan Jingtian was once exposed by his ex-girlfriend who knew him in a nightclub, saying that although he was very nice to every girlfriend, he would hold the other party in the palm of his hand, making the other party feel as if he would never cheat and change his mind, but he was not very nice to "ex-girlfriends", and would often complain about his ex-girlfriends. However, although the act of cheating is really undesirable, Joanna still praises Ruan Jingtian’s sexual ability. He said that he can last for an average of half an hour at a time, and the longest is an hour. He also said that Ruan Jingtian attaches great importance to foreplay, and is very gentle and not rude at all. When the two of them are together, they almost come twice a day!

　　In addition, Joanna even more explodes Ethan’s peculiarity, she said that during the 9 months of their relationship, Ethan did not like to wear condoms, and preferred some special positions, so Joanna had to take contraceptives to protect him in order to be considerate. However, the most exaggerated thing is that when Ethan broke the news with Xu Weining, he also asked Joanna to fight in Kenting for 3 days, because Ethan said that he and each girlfriend must do it one last time before breaking up, and then dumped Joanna. In short, when it comes to Ethan, Joanna seems to love and hate.

Zhiji L7 Angel Wheel will be delivered in the first quarter of next year at the earliest, and the interior of Zhiji L7 will be officially made public at the upcoming Guangzhou Auto Show. This new electric luxury brand, which was established only one year ago, is accelerating its way to people with a speed that exceeds that of any previous car companies.

This time, we got a close look at the excellent performance of Zhiji L7. Although it is still an engineering vehicle, the mechanical hardware and adjustment of the vehicle have been locked. In a word, it is a product with performance comparable to that of a million-level high-end luxury car, and it is the most fun car in the history of SAIC.

In a test field, the ground was printed with black marks left by the friction between the tire and the ground after drifting in circles. A senior technician said that this is the first time that a performance car has left its mark since the test site was put into use, and this mark was left by Zhiji L7.

What kind of performance car has Zhiji built? The authoritative data measured by this group of national motor vehicle product quality inspection and testing centers can make you better understand.

The acceleration of 3.87 seconds, the braking performance of 32.69 meters and the steady-state maximum lateral acceleration of 0.968G can be seen in the video at the beginning of the article.

In addition to the official measured data, there are also excellent performance, such as more than 10 consecutive full-power ejection starts, 50: 50 front and rear car body weight ratio, 0-100% real-time dynamic intelligent adjustment of front and rear axle torque, 100% kinetic energy recovery efficiency and 10.8m turning diameter. Any one of these achievements is worth talking about a lot, and the space problem is only briefly discussed from two hardware modules: motor and brake.

Heat dissipation is a systematic project for electric drive, and it is also one of the most difficult problems to solve. At present, the common practices in the industry are oil cooling heat dissipation, flat wire winding and motor thermal management system. Zhiji L7 has brought in a "Ao Bai" family bucket, and collected these mainstream schemes.

Compared with Tesla’s winding end oil cooling scheme, Zhiji L7′ s straight waterfall oil cooling structure can cool the winding end and core at the same time, which improves the sustainability by 46% compared with the current mainstream water cooling scheme. This innovative motor cooling structure has been applied for an international patent.

In addition, this motor also uses 8 layers of Hair-pin flat wire winding, which is simply to change the original round winding wire into a winding wire with a flat rectangular cross section. This has many advantages, for example, lines can be closely attached to each other, which improves the slot full rate and brings about the improvement of the overall power density of the motor. It can be understood that in the same refrigerator, you must pack more Wangzai milk in square cartons than in round cans, so that your refrigerator utilization rate will be higher.

For heat dissipation, the larger the cross-sectional area of the flat wire in the same space, the smaller the resistance, and the less the heat generated. In addition, the flat wire has a larger heat dissipation contact surface, which can achieve excellent heat dissipation effect with oil cooling. This is easier to understand, and your cooking is also cut into squares as much as possible, rather than columns, because the contact area is larger, which is conducive to heat conduction.

In addition to the hardware, Zhiji L7′ s motor cooling is also equipped with a thermal management system, which intelligently controls the electronic oil pump through algorithms, and sprays wherever it is too hot. Because the local temperature of the motor will be different under different working conditions, with the algorithm blessing, the heat dissipation can be done more accurately.

Why does Zhiji L7 have to work hard to maximize heat dissipation? Because Zhiji wants too much, he wants small size, high power, good performance, good HVH and low energy consumption.

Fortunately, although the design requirements are harsh, the engineers still meet them one by one. The high-efficiency and high-power permanent magnet synchronous motor mounted on the rear axle of Zhiji L7 solves the heat dissipation problem, achieves the same high performance as asynchronous induction motor, and gives full play to the advantages of small size, good NVH and low energy consumption of permanent magnet synchronous motor.

Thanks to this design, Zhiji L7 can not only achieve dual-motor four-wheel drive, but also break 100 in 3.87 seconds. It can also keep the front of the car in a low posture, and achieve an ultra-low drag coefficient of 0.21Cd. At the same time, with the mute design, the mute level is 3~6dB ahead of the industry.

The braking distance of 32.69 meters is largely due to the customized bembo braking system, including high-performance four-piston all-aluminum calipers and customized large-size high-performance brake discs. Many models only use brembo’s calipers and don’t buy brake discs. They also use brembo to support the scene, and there is little "Ao Bai" like Zhiji L7.

The size of the high-performance ventilation disc of Zhiji L7 is 365mm before and 356mm after, which has reached the level of a million-class performance vehicle. The larger braking friction area can bring better braking response and extremely low thermal attenuation.

In addition to performance, Zhiji L7 also gives consideration to energy efficiency. Zhiji L7 also uses the Onebox fully decoupled brake control system provided by Continental. At present, the mainstream scheme on the market is Twobox system, and the mechanical braking and regenerative braking can’t be decoupled. The intuitive feeling is that when the assisted driving is enabled, the ACC system controls the acceleration and deceleration, and your brake pedal will follow. If the AEB system is enabled, it just happens that your foot is under the brake pedal, and you will probably go to the hospital to hang the orthopedics.

The influence of Twobox system on energy consumption lies in that when you step on the brake, mechanical braking will definitely step in and consume part of kinetic energy, while the rest will flow into the kinetic energy recovery system, and the recovery efficiency is only 60%-70%. Onebox fully decoupled braking control system, when stepping on the brake, can completely rely on kinetic energy recovery to achieve deceleration when the deceleration is less than 0.3 g, and the mechanical braking part will only intervene when it exceeds 0.3 g, so that 100% kinetic energy can be recovered, and it can be called Lu Hua peanut oil-squeezing expert in kinetic energy recovery field. In addition, the Onebox fully decoupled brake control system can realize more flexible adjustment of the brake pedal and provide redundant braking for high-level intelligent driving.

As said in the video, Zhiji L7 reveals an ultimate pursuit of perfection, which is very difficult for such a complex product as intelligent electric vehicle.

The high-level assisted driving realized by the large computing chip and lidar, the liftable screen and 22 speakers create an intelligent cockpit with the ultimate sense of science and technology, and the driving performance that can be rushed out, braked firmly and manipulated flexibly. Zhiji’s pursuit for the ultimate is far more than that.

The paranoid pursuit of perfect quality can promote the perfect integration of scientific and technological progress and user experience. Perfection is difficult, but we can see that Zhizhi is already on the way to perfection.

　　CCTV News:Researchers announced on the 3rd that two serious security vulnerabilities have been found in computer chips, involving a large number of computers and smart phones around the world, which may be the most influential security vulnerability in computer history.

　　Google announced on the 3rd US time that its team and technicians from many countries have jointly discovered two chip-level security vulnerabilities, through which hackers can illegally read system memory and steal key information such as passwords. One of the vulnerabilities involves almost all CPU chips produced by Intel in recent years, and the other vulnerability affects chips produced by Intel, AMD, a semiconductor company of Chaowei, and ARM Technologies, UK. That is to say, almost all desktop computers, notebook computers and Internet servers using Intel’s CPU, as well as computers, smart phones, tablets and other intelligent devices using chips from Intel, AMD, and ARM Technologies, may be recruited.

　　Major manufacturers have introduced security patches one after another.

　　However, the researchers said that they had discovered these two vulnerabilities in the middle of last year and informed major manufacturers. Over the past six months, various companies have been making security patches to fix these two vulnerabilities. At present, both Microsoft and Apple have prepared security patches for their desktop computer operating systems, and Google also said that smartphones using the latest version of Android operating system are also safe. It is not clear whether Apple’s iphone and ipad tablets are also affected by these two security vulnerabilities.

　　No sign of vulnerability being exploited by hackers has been found yet.

　　The BBC quoted the British network security agency as saying that users don’t have to worry too much. So far, there are no signs that these two vulnerabilities have been obtained and exploited by hackers, so it is only necessary to update the security patches of major manufacturers in time. However, some media also said that security patches may slow down the system, and the degree of slowdown may be between 5% and 30%. Intel denied this statement.

　　Core reading

　　On January 21st, the results of the second batch of centralized drug procurement organized by the state were released, and 32 varieties were successfully purchased, with an average price drop of 53% and the highest drop of 93%. Many drugs selected this time are commonly used by ordinary people, involving diabetes, hypertension, colds and fever, etc., and more patients will benefit.

　　The commonly used drugs such as Baitangping for diabetics, indapamide tablets for hypertensive patients and acetaminophen for colds and fever have been reduced by more than half!

　　On January 17th, under the guidance of the National Medical Insurance Bureau and other departments, all provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps formed a procurement alliance, and the second batch of centralized procurement of drugs organized by the state was carried out in Shanghai, resulting in the result of quasi-winning. 32 varieties were successfully purchased, and compared with the lowest purchase price in the alliance area in 2018, the average selected price decreased by 53%. On January 21st, the result of the election was officially released.

　　The highest drop in drug prices reached 93%

　　Of the 33 varieties collected this time, 32 were successfully purchased, and a total of 100 products were selected. 122 enterprises participated, resulting in 77 enterprises to be selected. Compared with the lowest purchase price in the alliance area in 2018, the proposed bid price dropped by an average of 53%, with the highest drop reaching 93%.

　　After this round of centralized collection, it means that there are more commonly used drugs to reduce prices, that is, 25 drugs selected before, and 32 varieties this time. The 32 varieties contain many drugs that people are familiar with, such as acetaminophen, antibiotics amoxicillin, clindamycin hydrochloride, azithromycin and cefradine, acarbose and glimepiride for diabetes, metronidazole tablets for toothache, indapamide tablets for hypertension and bisoprolol fumarate. The price reduction of these commonly used drugs will benefit more patients. For example, Bayer Acarbose Tablets (50mg30 tablets), the original drug, with the trade name of Baitangping, is used in a very large amount among Chinese diabetics. This quotation is 0.18 yuan per piece, with a drop of more than 90%.

　　On the 17th, 122 of the 33 enterprises preparing to purchase varieties declared their prices, including the original research drugs and generic drugs that passed the consistency evaluation. Four original drugs were significantly reduced in price, and they were successfully shortlisted for the selected results.

　　This centralized procurement is still the general idea of "national organization, alliance procurement and platform operation", adhering to the principles of purchasing with quantity, integrating recruitment and procurement, and ensuring use, and taking conformity evaluation as the condition for the shortlisting of generic drugs. Medical institutions and retail pharmacies designated by medical insurance can participate voluntarily.

　　"The second batch of state-organized centralized purchasing manufacturers can be multiple, up to six, maintaining moderate competitiveness. According to the number of selected manufacturers, the dosage is agreed to be 50% to 80% respectively. At the same time, maintain a reasonable price gap between different selected enterprises for the same drug. Among the short-listed manufacturers to be selected, the lowest quotation is given priority to two regions to ensure the dosage and protect the enthusiasm of enterprises. " Ding Jinxi, a professor at China Pharmaceutical University said.

　　In the next step, all localities will focus on the implementation of the selected results, and patients are expected to use the selected drugs from April this year.

　　Guaranteed dosage of low-priced drugs

　　In the "4+7" pilot project, the original drug appeared "patent cliff" for the first time, and the price was greatly reduced. This collection was not unexpected. For example, the price of acarbose, Bayer’s diabetes drug, was reduced by more than 90%, and meloxicam tablets, Boehringer Ingerham’s drug for rheumatoid arthritis, was reduced by more than 80%.

　　However, some drugs that were originally low-priced in history have returned to low-priced positions in this collection, and the dosage has been guaranteed to ensure a stable supply. For example, acetaminophen is 0.03 yuan per tablet, metronidazole is 0.05 yuan per tablet, and amoxicillin is 0.05 yuan per tablet.

　　These prices are just a few cents, but they are not generally used by people. This is because for the convenience of bidding, enterprises quote in the smallest unit of preparation (tablets, granules, sticks and bags), while in real life, people pack drugs in boxes, bottles and other units. For example, the centralized purchase of acarbose from an enterprise, the proposed bid price of 0.18 yuan is the price of each tablet, while patients buy it in boxes, and the converted price is 5.42 yuan per box.

　　So, are these prices higher or lower than international prices?

　　Guangdong dongyangguang pharmaceutical co., ltd, in this centralized procurement, three products were shortlisted, and two products were ranked first, which was the lowest among the prices to be selected for this variety. Two products to be selected are moxifloxacin hydrochloride and olmesartan medoxomil, which were originally sold abroad and just listed in China. Among them, the proposed bid price of moxifloxacin hydrochloride is 6.66 yuan.

　　According to Chen Yangui, the executive director of the company, the centralized purchasing organized by the state has made the market return to rationality. The company has strong technical force and strong supply chain, and it has great advantages to return to the domestic market, so it participated in the second batch of centralized purchasing. "The quotation for the shortlisted qualification is similar to that in the European and American markets."

　　Inquire about the price of moxifloxacin hydrochloride of the same specification abroad, and the public price is RMB 8 yuan and 9 yuan. Feng Chang, a professor at China Pharmaceutical University, explained that the actual settlement price is often lower than the public price, and China has a large market share, so there is not much difference between the two. "Enterprise quotation has its own development strategy considerations, which are normal market behaviors."

　　Some experts estimate that in the past, the price of generic drugs in China was more than twice the international price. After purchasing with quantity, it returned to the international normal price. Expert research has found that the part that is higher than the reasonable price occurs in the intermediate link, which is not included in the quality links such as production and research and development. Squeezing out this part of water will not affect the quality of drugs, nor will it affect the development of enterprises.

　　An original research drug of Boehringer Ingerham, which has been on the market for more than 20 years, entered the scope of the proposed selection this time. The drug has already passed the patent period. Although the price has been reduced by 80%, the company originally sold it mainly in Shanghai, Beijing and some provincial capitals. After entering centralized purchasing this time, the sales market has expanded to half of China. "We actively participate in and cooperate with China’s national policies." Zeng Chenghui, head of the company’s regional expansion business department, said.

　　The person in charge of the National Pilot Office and the Joint Procurement Office believes that the main reasons for the sharp price reduction of selected drugs are as follows: the state organizes centralized procurement and use of drugs, which truly realizes the integration of procurement with quantity and recruitment, and gives clear expectations to pharmaceutical manufacturers, which is conducive to their independent quotation and declaration according to the purchase volume, squeezing out unreasonable virtual space; Further improve the procurement rules, and realize the function of market price discovery through open and sunny competition; Timely settlement of payment for goods significantly reduces the capital cost of enterprises and leaves room for price reduction.

　　By purchasing with quantity and ensuring the use, enterprises no longer need to carry out sales public relations, "a batch of low-priced drugs ‘ Resurrection ’ It is also a return to international practice. " The person in charge said.

　　The burden on patients is significantly reduced.

　　According to the person in charge of joint procurement, the "4+7" pilot project and expansion are progressing smoothly.

　　The implementation of procurement in pilot cities exceeded expectations and the agreed procurement volume was completed ahead of schedule. By the end of December 2019, the average procurement progress of 25 "4+7" pilot areas for selected drugs was 183%, and the selected drugs accounted for 78% of the purchases of drugs with the same generic name. All the expanded areas have started to implement the results of the expanded procurement in December, and patients all over the country have used the drugs selected by centralized procurement with high quality and low price.

　　Due to the sharp drop in prices, the burden on patients has been significantly reduced. In addition, judging from the situation in the "4+7" pilot areas, the proportion of people using generic drugs and original drugs that have passed the consistency evaluation has greatly increased from about 50% to over 90%, which has significantly improved the quality level of people’s drug use.

　　Chen Qiulin, director of the Social Security Research Office of the Institute of Population and Labor Economics of China Academy of Social Sciences, said that the centralized drug procurement organized by the state is different from the previous recruitment, and it is beneficial to patients, doctors, enterprises, medical insurance funds and other parties, forming a benign mechanism. "Centralized procurement based on the consistent evaluation of quality and efficacy has prompted enterprises to return to cost and quality competition and fundamentally improved the ecological environment of the pharmaceutical industry. At the same time, it becomes a push ‘ Three medical linkage ’ The important entry point, policy connectivity and synergy, play a superposition effect. "

　　The person in charge of the pilot office said that the next step will be to establish a normalized and standardized centralized procurement system based on the improvement of the "4+7" pilot and expansion and the experience of the second batch of countries in organizing centralized procurement and use of drugs, and to include more products in centralized procurement. "Let the new procurement model, marketing method and industry ecology become the leading forces."

　　According to Ding Yilei, deputy director of the Price and Procurement Department of the National Medical Insurance Bureau, the scope of centralized procurement was fully covered, and the varieties with sufficient competition and stable supply were selected for one tender and national implementation, and the rules were further improved. "In the future, according to the practice of this round of centralized procurement, the centralized procurement of drugs organized by the state will be normalized, and qualified varieties will be included in the scope of centralized procurement."
