Recently, Jietu Shanhai T2, a compact SUV—— owned by Jietu brand, officially opened for pre-sale. The new car has launched three models with a pre-sale price range of 184.9-216.9 million yuan. According to the plan, the new car will be listed at the 2024 Beijing Auto Show.

Jietu Shanhai T2 can simply understand the hybrid version of Chengjietu Traveler, and launch three models in advance, including two models with pure electric battery life of 129 kilometers and one model with pure electric battery life of 208 kilometers. In terms of appearance, Jietu Shanhai T2 basically continues the design layout of the fuel version, and still adopts the square box hard-core shape. The front air intake grille is equipped with six black square convex structures and carries the English LOGO "JETOUR". At the same time, the LED headlight group forms a square retro shape, and the headlights are built into the shape of lanterns as a whole, which is combined with the traditional culture of China. The bottom bumper is painted in black, and the center is equipped with a double trailer hook, which increases practicality and highlights the hard-core atmosphere. In addition, the front enclosure of the new car is equipped with a large-size guard plate, which shows the wildness of the vehicle.

On the side of the car body, the square shape and the protruding wheel arch conform to the gas field of the hard-core SUV, and the shape of the wheel eyebrows protrudes outward to show the hard-core style, and it also adopts the design of suspended roof. In the rear part, Jetway Shanhai T2 has an external spare tire, and the rear enclosure adopts a rather tough design, which can form a good echo with the front enclosure design. In terms of dimensions, the length, width and height of the new car are 4785/2006/1880mm and the wheelbase is 2800mm respectively.

In the interior part, Jetway Shanhai T2 is no different from the fuel version. The center console also uses many linear elements, equipped with LCD instrument panel (10.25 inches) and suspended central control large screen (15.6 inches), with double flat-bottomed steering wheel, and the air conditioning outlet adopts vertical style.

In terms of power, as a plug-in hybrid vehicle, Jietu Shanhai T2 is equipped with a hybrid system consisting of a 1.5T engine. The maximum power of the engine is 115kW, the peak torque is 220N·m, the comprehensive maximum power of the system is 280kW, and the comprehensive maximum torque is 610 Nm. At the same time, Jietu Shanhai T2 adopts Contemporary Amperex Technology Co., Limited Electric’s 43.24kWh battery pack matching Kunpeng Super Hybrid C-DM system, which provides Jietu Shanhai T2 with pure battery life of 208km and long comprehensive battery life of 1,300 km+.

Jietu Automobile is a new product series launched by Chery Holding Group on January 22, 2018. It once belonged to Kairui Automobile. At the beginning of its launch, it adopted a model strategy of high allocation and low price, and quickly relied on Chery’s channel end for layout. At present, it has Jietu X90 series, Jietu X70 series, Jietu Dasheng series and other products. In 2023, it sold 203,700 new cars, and the X70 series with the highest sales volume of 99,800 vehicles.

Now, after laying a "survival line" supported by SUV products such as X70 series, X90 series and Dasheng, Jetway is cutting into the hard-core off-road market through products such as Jetway Traveler. In September 2023, Jietu Traveler went on the market. The new car was positioned as a medium-sized hard-core off-road SUV, offering five-and seven-seat models. The power was equipped with 1.5T and 2.0T engines, of which 1.5T was 139,900-149,900 yuan and 2.0T was 15.99-184,900 yuan.

Stepping into hard-core off-road is also an important direction for independent brands to achieve brand upward. Compared with cars and SUVs, the off-road vehicle market still has room to be tapped. However, with the layout of brands such as Dongfeng Warrior, Wangwang and Equation Leopard, it is obvious to the naked eye that the market pressure has started to rise, and it is obviously not easy for Jietu to share a bowl of soup in this market. For Jetway, it is still unknown whether it can gain attention in the hard-core off-road market. In recent years, Jietu Automobile has never completed the set sales target. In 2023, the sales target is 300,000 vehicles, while the actual sales volume is only 200,000 vehicles, which is still a long way off. Therefore, "hard cross-country" is a battle that cannot be lost in front of Jietu, but is Jietu ready?

　　Beijing, July 22nd (Reporter Qiu Yu), the client of Zhongxin. com, lasted only 259 days! Since its establishment was announced on November 5, 2018, the first batch of 25 companies in science and technology innovation board were listed on July 22, 2019, that is, science and technology innovation board shares can be officially traded.

　　Science and technology innovation board’s stock trading rules are quite different from the current A-share rules. Since there is no limit on the price increase and decrease in the first five trading days, how the intraday stock price will fluctuate has attracted much attention. So, how do individual investors participate in science and technology innovation board? What problems should we pay attention to?

　　How do individual investors participate?

　　If individual investors want to participate in science and technology innovation board stock exchange, there is a certain threshold, and they need to meet the following conditions:

　　The daily average assets in the securities account and capital account in the 20 trading days before the opening of the application authority are not less than RMB 500,000 (excluding the funds and securities that the investor has integrated through margin financing and securities lending); Participated in securities trading for more than 24 months.

　　In other words, you must have not only two years of experience in securities trading, but also at least 500,000 yuan in your account. The relevant person in charge of the Shanghai Stock Exchange said at the end of June that there are about 3.2 million investors who meet the requirements of appropriateness.

　　It doesn’t matter if the above conditions are not met. According to the Shanghai Stock Exchange, small and medium-sized investors who don’t meet the requirements of investor suitability can participate in science and technology innovation board through products such as Public Offering of Fund.

　　At present, Bosera Fund, Yin Hua Fund, Dacheng Fund, China Europe Fund, Caitong Fund, CICC Fund and other fund companies have launched science and technology innovation board-related theme funds.

　　How do individuals participate in innovation?

　　Playing new means that investors use funds to participate in the subscription of new shares. If they win the lottery, they will buy the shares that will be listed soon, mainly through online and offline channels.

　　Since the offline subscription object does not include individual investors, for ordinary individual investors, they can only participate in innovation through online subscription.

　　If you want to purchase online, the first step is to open the science and technology innovation board trading authority, that is, to meet the above conditions.

　　The second step is to meet the requirement of holding market value, that is, the total market value of the unrestricted A shares and unrestricted depositary receipts held by individual investors who participate in the subscription of new shares in science and technology innovation board is more than 10,000 yuan (including 10,000 yuan).

　　For example, if you have bought more than 10,000 yuan of Shanghai Pudong Development Bank (stock code: 600000.SH) shares in your stock account, and meet the above conditions for participating in science and technology innovation board, you can participate in the IPO in science and technology innovation board. Because the stock codes 601 and 600 start with the Shanghai Stock Exchange. The stock at the beginning of 000 is the main board stock of Shenzhen Stock Exchange; 002 starts with small and medium-sized stocks of Shenzhen Stock Exchange, and 300 starts with GEM stocks of Shenzhen Stock Exchange.

　　In addition, there is another way to invest in bank wealth management and fund participation in innovation. For example, at present, Bank of China, China Merchants Bank, Postal Savings Bank and other banks have launched science and technology innovation board-themed bank wealth management products, mainly by investing in innovative funds to indirectly participate in innovation in science and technology innovation board.

　　Are new shares "bought as earned"?

　　Many people think that buying new shares means earning, just like winning the lottery. The data shows that the number of investors participating in online innovation has exceeded 3.1 million. This means that almost all individual investors who have opened the trading authority in science and technology innovation board have participated in the innovation.

　　In fact, science and technology innovation board’s new shares are not cheap.

　　Price-earnings ratio (PE) is the ratio of stock price divided by earnings per share, and it is one of the most commonly used indicators to evaluate whether the stock price level is reasonable. Generally speaking, the higher the P/E ratio, the more overvalued the stock is.

　　The upper limit of 23 times P/E ratio has been cancelled in the issue price of science and technology innovation board shares, so the average P/E ratio obviously exceeds the overall level of A shares.

　　According to the statistics of Pacific Securities Research Report, the P/E ratio of 25 companies is between 18.86 and 170.75 times, with an average of 49.16 times and a median of 42.14 times.

　　Among them, the highest P/E ratio is Zhongwei Company, 170.75 times; The lowest is China’s through number, 18.8 times. The P/E ratios of China Tonghao, Wald, Tianyi Shangjia and Aerospace Hongtu are lower than the industry level, and the remaining 21 companies are all higher than the industry valuation.

　　Judging from the issue price, according to Wind data, the average issue price of the first batch of 25 new shares listed in science and technology innovation board is 29.20 yuan/share. As of July 15th, of the 87 A-share new shares issued this year, only 21 were issued at a price exceeding 29.20 yuan/share.

　　In addition, in terms of winning rate, the average winning rate of the first batch of 25 science and technology innovation board new shares is nearly 0.06%, which is higher than the overall level of A shares.

　　What problems should we pay attention to in trading?

　　Science and technology innovation board’s trading rules are different from the current rules of A shares.

　　First, the price rises and falls. There is no price limit in the first five trading days after the listing of science and technology innovation board stock, and a 20% price limit is set from the sixth trading day.

　　In the first five trading days, science and technology innovation board also set up a temporary suspension system. When the intraday share price rises or falls by 30% or 60% compared with the opening price for the first time, it will be suspended once respectively.

　　In this regard, some market analysts have warned that if there is no price increase or decrease, it is very likely that investors will be "hung at high altitude" after buying; The price limit of 20% is twice as large as the current limit of 10% A shares, and the trading risk is higher.

　　Secondly, the number of single declared shares in science and technology innovation board is different from the current 100 shares in A shares, and its starting number is 200 shares. Moreover, as long as each declaration exceeds 200 shares, it can be increased by 1 share, for example, 201 shares and 202 shares can be purchased.

　　Finally, it should be noted that science and technology innovation board has not introduced the T+0 trading system, but still adopts T+1. T+1 means that stocks bought on the same day cannot be sold on the same day, and cannot be sold until the next trading day.

　　The relevant person in charge of the China Securities Regulatory Commission said earlier that at this stage, China’s capital market is still immature, the proportion of small and medium-sized retail investors in the investor structure is relatively large, the characteristics of the unilateral market have not fundamentally changed, and the market monitoring means are still insufficient. Starting from maintaining the stable operation of the market and protecting the interests of small and medium-sized investors, science and technology innovation board has not introduced T+0 trading system yet.

　　What is the impact on the trend of A-share main board?

　　Essence Securities pointed out that assuming that the turnover rate of most companies in science and technology innovation board reached 89% on the first day of trading, it is estimated that the turnover of science and technology innovation board on the first day will be about 31.394 billion yuan (assuming that the average transaction price exceeds the issue price by 35%), then science and technology innovation board will account for about 6.56% of the total turnover of the two cities, with little liquidity impact.

　　Huatai Securities analyzed that science and technology innovation board’s influence on the liquidity of the A-share main board mainly has two aspects, namely, the bottom warehouse drainage effect and the diversion effect.

　　On the one hand, science and technology innovation board’s increase in stock supply has created a certain diversion pressure on the trading volume of the existing A-share sector, which is in the two stages of issuance and listing; On the other hand, participating in the subscription of science and technology innovation board new shares requires the market value of A-share bottom positions, which is expected to increase the allocation funds of existing sectors.

　　Regarding the "diversion pressure on the existing A-share sector", GF Securities believes that the diversion effect brought by science and technology innovation board is limited and controllable due to the comprehensive mechanism and volume factors.

　　From the mechanism point of view, the Growth Enterprise Market (GEM) adopted the new subscription of new shares in advance, and the first batch of frozen subscription funds reached one trillion yuan, while science and technology innovation board only adopted the market value placement method, which greatly weakened the diversion effect; In terms of volume, the financing scale of science and technology innovation board is expected to be 80 billion to 90 billion yuan in 2019, and the overall pace is controllable.

　　Li Chao, vice chairman of the China Securities Regulatory Commission, said earlier that science and technology innovation board has strict corresponding standards and procedures, which does not mean that anyone who wants to go public can go public. At the same time, science and technology innovation board pays attention to the market mechanism, which includes market constraints. As long as all parties in the market, including intermediaries, issuers, investors, and regulatory authorities, return to their posts and do their duty, I believe there will be no flooding in science and technology innovation board.

Shield machine is called "the king of construction machinery" and is an important symbol to measure the manufacturing level of a country. Today, seven out of every ten shield machines in the world come from China. What kind of industrial chain support is behind this? Look at the reporter’s first-line research.

In the assembly workshop of China Railway Equipment, the largest shield machine enterprise in China, the reporter saw that a number of shield machines exported overseas were being delivered centrally. If this shield machine is disassembled, there are more than 10 thousand parts. As can be seen from this industrial chain map, cutters and main bearings are mainly concentrated in Henan, motors are mainly located in Shanxi, and gears are mainly distributed in the Yangtze River Delta and Chongqing. And if we go back to 10 years ago, these key components still have to rely on imports.

Cutters, like teeth, determine the tunneling speed of a shield machine. The materials used as cutters should be high in hardness, corrosion resistance, good in flexibility and fatigue resistance. In order to overcome this special material, China Railway Equipment and Tsinghua University jointly tackle key problems, and conducted thousands of tests on more than a dozen additive elements, finally solving the problem of high strength and toughness of superhard materials.

As the "chain length" in the industrial chain, China Railway Equipment has driven the development of more than 1,200 enterprises through this collaborative innovation mechanism for many years. In this warehouse, the reporter saw that there were fifty or sixty rows of shelves with accessories such as motors and hydraulic pumps, just like a "parts supermarket for shield machines". Now more than 160 local enterprises provide supporting products and services for shield machines.

At the same time, engineers are constantly promoting the renewal and upgrading of shield machines. The types of shield machines have increased from two 10 years ago to 15 now. Originally, they can only move horizontally, but now they can go up and down slopes, turn corners and operate vertically. Now, the shield machine in China is still developing towards intellectualization and "unmanned tunneling".

Thanks to China’s complete industrial chain and continuous iterative technological innovation, today, China’s shield machine has occupied 70% of the global market, with thousands of upstream and downstream enterprises. Only China Railway Equipment and shield machines have received more than 1,600 orders, which have been exported to more than 30 countries and regions around the world, ranking first in the world in terms of production and sales for six consecutive years.

　　China news agency, Washington, February 22 (Reporter Chen Mengtong) The number of deaths in COVID-19 in the United States exceeded 500,000 on February 22. On the same day, US President Biden held a ceremony at the White House to mourn the death of COVID-19, and ordered the national flag to be lowered at half-mast until 26th.

　　According to the data of Johns Hopkins University in the United States, as of 16: 24 EDT on 22nd (5: 24 Beijing time on 23rd), the cumulative number of COVID-19 deaths in the United States exceeded 500,000, reaching 500,071, and the number of infected people exceeded 28.17 million.

　　At about 17 o’clock, the White House lowered its flag at half mast. The National Cathedral in Washington rang 500 bells to mourn the death of COVID-19.

　　"500,071 people died." At sunset, Biden made a speech on the COVID-19 epidemic at the White House. There was a pause when he read the number.

　　Biden said that in the past year, the lives lost by COVID-19 in the United States "exceeded the total number of people killed in the First and Second World Wars and the Vietnam War". "As a country, we can’t accept such a cruel fate. We have been fighting the epidemic for so long, but we must refuse to become numb to sadness, and we must refuse to regard every life as statistics, a vague thing or news. "

　　On the day before Biden was sworn in, there were more than 400,000 deaths in COVID-19. At that time, he arrived in Washington for his first public event, that is, he went to the reflection pool in front of the Lincoln Memorial to attend the national public sacrifice ceremony for the dead in COVID-19.

　　In his speech on the 22nd, Biden once again called on the American people to unite to fight the epidemic. "Stay alert, keep social distance, put on a mask, and get vaccinated when it’s your turn."

　　He then stressed that the United States must end the "political differences and false information" in the process of fighting the epidemic, which have torn families, communities and countries and caused too many lives. "It was not Democrats and Republicans who died of the virus, but our fellow Americans, our neighbors and friends."

　　After the speech, the Bidens and Vice President Harris came to the south side of the White House to observe a moment of silence for the 500,000 COVID-19 dead in front of the Washington Monument. Black veil is hung at the main entrance on the first floor of the White House. 500 burning white candles are arranged from the first floor along the stairs on both sides to the terrace on the second floor.

　　Despite the recent steady decline in the epidemic curve in the United States, the cumulative number of deaths continues to rise. Data show that the number of deaths in the United States exceeded 100,000 on May 27th, 2020, 200,000 on September 22nd, 300,000 on December 14th and 400,000 on January 19th, 2021. It took more than one month for the death cases to range from 300,000 to 400,000 and from 400,000 to 500,000.

　　The mainstream media in the United States used "shocking milestones" to describe this day. The Associated Press said that 500,000 was once "an unimaginable number" for the United States.

　　Fauci, an American infectious disease expert, said that the COVID-19 epidemic has never been experienced in the United States in 102 years since the influenza pandemic in 1918. "People will keep talking about it in the coming decades.".

　　According to the data of the US Centers for Disease Control and Prevention, as of the 22nd, over 44.13 million people in the United States have received at least one dose of COVID-19 vaccine, accounting for 13.3% of the total population. According to the data model of the University of Washington, by June 1, the number of deaths in the United States may exceed 589,000.

　　Biden also said that unity is the "only way" for the United States to overcome the epidemic. "Only in this way can we avoid more pain and loss. Only in this way can these heavy milestones no longer become national mourning days that need to be commemorated. "

Big data promotes China’s economic and social innovation and development

— — Some Experiences of Studying the "Thirteenth Five-Year National Informatization Plan"

　　Internet Institute of CCID Research Institute Lu Feng

　　Recently, the State Council issued the "Thirteenth Five-Year National Informatization Plan", clearly proposing to establish a unified and open big data system, strengthen the planning and construction of data resources, build a unified, efficient, interconnected, safe and reliable national data resource system, promote data application, strengthen data resource management and pay attention to data security protection.

　　Data, like energy resources such as coal and oil, is a national basic and strategic resource. In the past two years, the ecosystem of China’s big data industry has been continuously improved, and the application and innovation of management services have emerged one after another. New services, new models and new formats have emerged, which has provided an important guarantee for promoting industrial transformation and upgrading, innovating social governance models and optimizing people’s livelihood security services, and has become an important driving force for China’s economic and social innovation and development. Accelerating the innovative application of big data in economic and social fields and promoting industrial innovation, management innovation, service innovation and governance innovation have become an important starting point for implementing the five development concepts of innovation, coordination, green, openness and sharing, and an important way to promote the economic and social innovation and development of China.

　　First, big data has promoted the innovation of industrial development model, promoted industrial transformation and upgrading, and improved quality and efficiency.

　　First, big data promotes the innovation of traditional industrial organization and operation mode, and makes the R&D, design, manufacturing, logistics and transportation and after-sales service of traditional industries more accurate, efficient and intelligent. The R&D design mode based on customer demand feedback big data effectively solves the problem of R&D design behind closed doors and makes enterprise R&D design more targeted and oriented. Logistics big data effectively solves the problem of information asymmetry in logistics and transportation, makes logistics resource scheduling more optimized and intelligent, and makes logistics resources such as logistics warehousing, vehicles and personnel more matched and efficient. Manufacturing big data solves the problem of the flow of production data workshops, makes the production flow line of enterprises more flexible, and effectively supports new manufacturing formats such as personalized customization, experiential manufacturing and network manufacturing. Long-distance operation and maintenance, online monitoring and other big data effectively solve the after-sales management and maintenance problems of large-scale mechanical equipment, strengthen the whole life cycle management of products, realize intelligent early warning of product failures, promote the optimal allocation of maintenance resources, and significantly shorten the maintenance cycle.

　　Second, big data has promoted the incubation of new information services, and information services in big data analysis and mining industries in various fields have risen rapidly. The rise of big data information services in the fields of marketing, credit reporting and internet finance has made the industrial economy develop more efficiently and healthily. The development of marketing big data information services has guided the business planning of enterprises, optimized the allocation of commercial resources, improved the efficiency of commercial marketing and achieved precise marketing. The development of credit big data information service has effectively solved the problem of asymmetric credit information between the two parties to the transaction, improved the reliability guarantee of the transaction, and made the development of business activities more trustworthy and healthy. The development of big data information services in Internet finance has reduced the operating cost of Internet finance, lowered the development threshold of inclusive finance, effectively solved the short-term funding gap of SMEs, and effectively supplemented traditional financial services.

　　Third, big data forces information and communication technology to accelerate innovation, which provides a rare historical opportunity for China’s information and communication industry to catch up and become stronger. Big data technology has forced the traditional stand-alone data storage and computing analysis mode to develop in the direction of network distributed storage and collaborative computing mode, put forward new requirements for host storage, network transmission and computing control, forced the upgrading of storage, transmission and computing technologies, and provided historical opportunities for Chinese enterprises to take advantage of the development opportunity of the Internet industry to promote the self-control of storage, transmission and computing technologies.

　　Second, big data has promoted the innovation of social governance model and accelerated the modernization of national governance capacity and governance system.

　　First, big data has improved the government’s social management ability, and the social management model based on big data has made social management more active, accurate and efficient. The collection, mining and utilization of municipal management big data such as urban pipe network, landscaping, city appearance, etc. have strengthened the real-time monitoring and intelligent management of urban basic operating components, optimized the allocation of municipal management resources, and promoted the green, clean, efficient and safe operation of the city. The collection, mining and utilization of traffic big data such as roads, railways, subways, water transport, aviation, etc. have effectively guided road traffic planning, promoted the optimization of transportation resource allocation, realized the real-time traffic diversion ability, improved the ability to predict traffic accidents, and better met the public’s needs for safe and efficient travel. The collection, mining and utilization of big emergency data such as floods, fires and typhoons have improved the ability to predict disasters, optimized the allocation and scheduling of disaster relief resources, strengthened the scientific evaluation of disaster development trends and promoted the reduction of disaster losses. The collection, mining and utilization of big data in urban planning make the layout of urban residential and industrial planning more scientific and reasonable, realize the rational tidal flow of population in the morning and evening, reduce urban traffic congestion, and promote the integration of urban livable and production cities.

　　Second, big data has improved the government’s macro-control ability and made macro-control more accurate and scientific. The collection, mining and utilization of financial big data, such as electronic payment, mobile payment and internet finance, have realized the precise control of financial operation by the state, and improved the comprehensive analysis ability of financial operation and the decision-making ability of financial regulation.

CCTV News:On the 10th local time, US Democratic presidential candidate Biden held a press conference, saying that his transition team had begun to prepare for the formation of a new government, and stressed that nothing could stop this. On the other hand, Republican presidential candidate and US President Trump said on social media that he would win the election and there was fraud in counting votes.

Biden said that Trump’s refusal to admit defeat made many Americans feel anxious. He thought Trump’s move was embarrassing and not good for his political legacy as president. He expressed his expectation to start a dialogue with Trump. When asked if he would take legal action to force Trump to admit defeat, Biden said he didn’t think it was necessary. However, according to CBS, Biden can’t officially start to take over the presidential power because the General Affairs Administration of the United States, which has officially opened the presidential power transfer procedure, has not officially determined the winner of the election. In this regard, an official of Biden’s campaign team who asked not to be named said that Biden would consider taking legal action to deal with the current situation.

On the other hand, Trump posted on social media twice on the 10th, saying that he would win, and there was fraud in counting votes in the general election. In an American Fox News program broadcast on the evening of 10th local time, White House Press Secretary Kelly McNarney said with a large stack of paper documents that it was 234 pages of sworn written testimony, which could prove that there was election fraud in this election. McNarney, for example, said that in wayne county, Michigan, 60% of the votes had the same signature, and 50 votes had been counted repeatedly. Bill Stepin, Trump’s campaign manager, said the day before that Trump was "not retreating" and "still fighting" and would continue to seek to initiate legal proceedings in several key States in response to the vote count results of the general election. However, according to US media reports, although the Trump campaign team is actively seeking donations to pay tens of millions of dollars in litigation fees and recount fees, some Republican donors have indicated that they are unwilling to continue to entangle in legal proceedings. These lawsuits will not change the current election outcome, and they have shifted their focus to maintaining the Republican majority status in the Senate.
