  Since the establishment of SAIC-Audi, we have speculated which product its domestic model is. With the exposure of a spy photo of a sedan Audi A7, we realized that SAIC-Audi did not introduce overseas Audi products into China in a hurry, but made localization adjustments for China consumers, which is the birth of Audi A7L. This release is the current version with a limited edition of 1,000 vehicles, which adopts the exclusive color of Qingshan Dai car paint, and each car will have its own number.

  SAIC Audi A7L based on MLB Evo platform is still eye-catching. The brand-new air intake grille is decorated with horizontal and vertical decorative strips, and the overall design is still the traditional hexagonal design of Audi family. LED laser matrix headlights also appear on the new car, which is the only model equipped with laser headlights in Audi domestic fuel vehicles.

  Regarding the headlights mentioned above, the Audi A7L adopts more advanced Audi intelligent laser headlights based on the high-definition matrix module. The headlight group of A7L contains 32 LED modules, which can be adjusted automatically according to the actual road conditions, and automatically avoid when other vehicles or pedestrians appear in the opposite direction. In this intelligent laser headlight system, there is an X-shaped optical focusing design, which increases the actual irradiation distance in the dark to twice that of ordinary LED headlights, that is, up to 600 meters. When the vehicle speed is above 70km/h, the headlights can be turned on intelligently and actively after sensor identification and processor calculation.

  Audi A7L, which is designed with a sedan structure, abandons A7 Sportback’s slip-back style, while maintaining a low car height and lengthening the wheelbase, which also makes the car body more stretched. The borderless electric suction door that everyone is very fond of has been preserved, so Audi A7L is still a medium and large four-door coupe. Similar styles can be found in BMW 6 Series or 8 Series four-door coupe models.

  In contrast, the shape of the tail is the biggest change, but the overall design is actually very harmonious, and the design of the headlight group has not changed, and it can still present a handsome "light show". Curious about how long the new car is, the puzzle of friends has finally been solved. The length of SAIC Audi A7L is 5076mm and the wheelbase is 3026mm, which is 100mm longer than A7 Sportback and 98mm longer than A7 Sportback.

  SAIC Audi A7L based on MLB Evo platform has not changed in the overall interior design, and it is still a layered center console design, with full LCD instrument panel and central control upper and lower dual-screen design. If you are an old Audi fan, then this set of interiors will definitely attract you with MIB3 entertainment information system. On the basis of inheriting the Audi Asterix ecosystem, it will introduce apps commonly used by Chinese people such as Cool Music and Himalaya. In the future, Audi will also cooperate with Tencent for a new round to develop scene services such as WeChat.

  Don’t think that a new car will lose its sporty atmosphere without a slip back. Sports seats are still provided inside the new car, supplemented by diamond-shaped stitching, thus increasing the sense of luxury. Even the back row continues to use sports-style integrated seats. Of course, since the wheelbase has been lengthened, the comfort of the second row of passengers must be improved. In addition to the legroom, the rear independent dual-zone air conditioner and seat heating are all available.

  The first version of Audi A7L will be equipped with DAWS dynamic all-wheel steering technology, which is the first time that this technology has been applied to Audi domestic models. When the vehicle is turning at a speed below 60km/h, the rear wheel and the front wheel form a reverse direction, achieving a steering angle of at most 5 degrees, which can greatly reduce the turning diameter (1.1 meters). In the usage scene above 60km/h, the DAWS dynamic all-wheel steering technology can make the rear wheel and the front wheel coordinate steering, and can achieve up to 2. When running on the expressway, A7L can complete the lane change process faster and make the whole body slide obliquely.

  Audi A7L’s active air suspension can automatically adjust the height and damping hardness according to the vehicle speed, driving mode and road conditions, so as to ensure the comfort or movement during driving. For example, after driving at a high speed for a period of time, A7L can automatically reduce the height of the car body (down 10 mm) for better aerodynamics and lower fuel consumption and NVH. When dealing with some offroad conditions, the height of the car body can be automatically adjusted upwards (up to 20mm).

  In terms of power, the first SAIC Audi A7L 55TFSI quattro is equipped with a 3.0TFSI V6 engine and matched with a 48V light mixing system, with a maximum power of 250kW and a peak torque of 500 Nm. In terms of transmission, it is matched with a 7-speed dual-clutch gearbox and a quattro four-wheel drive system. It is worth mentioning that domestic models will be equipped with air suspension and four-wheel steering system.

● Audi Concept Shanghai concept car

  Although the Audi Concept Shanghai concept car still covers some positions as a whole, it is not difficult to see the overall design style. It is a product based on the MEB platform of Volkswagen Group, which is very similar to the Audi Q4 e-tron concept car released in 2019, but the details have been adjusted.

Home of the car

  The headlight group of the new car is still Audi’s usual LED pixel matrix design, and the iconic hexagonal air intake grille is made of semi-closed material similar to aluminum alloy style. At the same time, the front bumper design is the biggest feature that is different from Q4 e-tron, and adopts a triangular design similar to Audi e-tron.

  From the side, we can clearly see the body structure brought by MEB platform. At the same time, the new car is longer than the Q4 e-tron which has been mass-produced on the same platform. In contrast, the through taillight group is extremely simple in shape, and the interior is decorated with LED light sources, so the visual effect at night is excellent.

  In terms of power, SAIC Audi has not disclosed the power parameters of the new car for the time being, but we expect that the new car will share the powertrain with other Audi models on MEB platform after mass production, providing three power models, including single motor and front and rear dual motors: 35 e-tron, 40 e-tron and 50 e-tron. Officially, it has a maximum cruising range of 560km and a battery capacity of 83.4kWh.

Editor’s comment:

  This night activity of SAIC-Audi shows us the future development direction of Audi’s second joint venture company in China. In the era of smart cars and new energy vehicles, SAIC-Audi will continue to create products that belong to Audi’s luxury brand image for China consumers, and at the same time, it is embracing changes to meet more challenges in the new energy market through pure electric vehicles. In 2021, SAIC-Audi set sail, and we believe that this will also help Audi brand to go more steadily and further in China. (Text/car home Wuyuan)

How can we get mathematical thinking? Expert: Doing the problem is the first way.

  Cryptologist Wang Xiaoyun recently won the 2019 Future Science Award for Mathematics and Computer Science. She puts forward the collision attack theory of cryptographic hash function, which promotes the design of a new generation of cryptographic hash function standards, has been widely used in important fields such as finance and transportation, and has made important contributions to supporting network information security.

  Mathematics, as the foundation of natural science, its strength often affects the national strength. Almost all major discoveries are related to the development of mathematics, which is an indispensable basic tool for studying and studying modern science and technology.

  A few days ago, the Ministry of Science and Technology, the Ministry of Education, the Chinese Academy of Sciences and the Natural Science Foundation of China jointly formulated the Work Plan on Strengthening Mathematical Science Research, which emphasized the importance of mathematical research.

  Mathematics is the foundation of natural science and major technological innovation and development, and has become an indispensable and important support in the fields of aerospace, national defense security, biomedicine, information, energy, ocean, artificial intelligence, advanced manufacturing and so on. So, what is the essence of mathematics? The Economic Daily reporter interviewed professional math researchers and math enthusiasts, trying to solve it.

  How to understand mathematical thinking

  Zhou Chuan, an associate researcher at the Institute of Mathematics and Systems Science of China Academy of Sciences, believes that the essence of mathematics lies in mathematical thinking. "Mathematical thinking refers to the ability to use mathematical ideas and methods reasonably in the process of thinking and solving problems. Mathematical thinking is not a kind of knowledge, but a kind of ability. Mathematical thinking is the most important foundation for building the mathematical world. It plays an important role whether it is pure mathematical learning and mathematical research or applying mathematical tools to other fields. " Zhou Chuan said.

  Specifically, mathematical thinking includes logical thinking, image thinking and spatial abstract thinking. It is like the huge root system of the towering tree of mathematics. Although it is invisible from the outside, it provides an important source of nutrition for mathematics. "We often say that mathematics is beautiful, and this beauty is mainly reflected in the beauty of its thinking." Zhou Chuan said.

  The beauty of mathematical thinking lies in the balance between practicality and rationality. Zhang Jian, a math enthusiast, told reporters that taking statistics, one of the branches of mathematics, as an example, in the process of solving practical problems, statistics gives people a concise and lively aesthetic feeling. Basic statistical laws, such as the law of large numbers, the central limit law and Bayesian probability, show the harmony after the conceptual world and the perceptual world are consistent. A series of theorems behind it play an important role in the balance and unity of reason and experience, theory and practice, deduction and induction, axiomatic system and algorithm program. "The data show that some precise sciences can be developed by clear definition and logic, and some problems need to be solved by approximate measurement, which requires statistical wisdom such as error theory, probability theory and mathematical statistics." Zhang Jian said.

  The beauty of mathematical thinking lies in the beauty of "overlord" above other disciplines. According to the data, the foundation of modern science is the Elements of Geometry written by Greece 2,500 years ago. Any discipline that can be called science must have two characteristics: first, it has an axiomatic system like the Elements of Geometry; Second, the hypothesis can be verified by experiments. Physics is based on mathematics, chemistry is based on physics and biology is based on physics and chemistry. In the final analysis, all modern science is based on mathematics. "For example, in the field of artificial intelligence, all the mathematical foundations of machine learning based on neural networks are partial differential equations and linear algebra, while other schools of artificial intelligence involve probability theory and stochastic processes. Today’s artificial intelligence is difficult to leave the blessing of big data and its related statistical variables. In order to make achievements in this field, solid and advanced mathematics literacy is indispensable. " Zhang Jian said.

  Zhou Chuan believes that the beauty of mathematics lies in its profound definition, clear logic and concise result. For example, the famous Goldbach conjecture that "any even number greater than 4 can be written as the sum of two prime numbers" is concise but profound and wonderful. Hardy, a great British mathematician, once said, "Beauty is the touchstone of good mathematics, and ugly mathematics cannot last forever". Hardy’s idea is related to his advocating the artistry of mathematics, but it also reflects the mathematicians’ aesthetic pursuit of mathematical theory to some extent.

  How to have mathematical thinking

  Mathematical thinking is so important, how can we get it? Doing the problem is the first way.

  Zhou Chuan told reporters that the purpose of doing the questions is to test the mastery of knowledge, strengthen the cognitive understanding of knowledge and develop thinking. Any scientific research is a process of trial and error, and mathematical research is no exception. "When faced with a mathematical problem, we usually make bold assumptions, divergent thinking, try a variety of different ideas, and carefully deduce and prove to see which idea is feasible and beautiful." Zhou Chuan said, "Doing problems can help mathematicians deepen their knowledge understanding, develop innovative thinking and stimulate innovative ideas, which are of great benefit to scientific research."

  Zhou Chuan believes that mathematical research will not be smooth sailing. For real problems, the ideas and methods that are usually easy to think of are often not effective. This requires maintaining enough courage and perseverance in mathematical research. When encountering difficulties, we must have the courage to "open the road and meet the water" and strive to move forward until the destination, although this process may be very long.

  In addition, it is also important to read more famous mathematical books. Sunny, a math researcher, told reporters that his desk has kept classic works such as Introduction to Advanced Mathematics by Hua Luogeng, Ancient and Modern Mathematics Thoughts by Maurice Klein and Princeton Mathematics Guide all the year round. "The whimsy in these books often gives people inspiration, which makes us professional mathematics researchers shine and gain valuable innovative ideas."

  In Sunny’s eyes, most famous mathematical works are concise and to the point, which will inspire both professional researchers and staff in other fields. For example, in the third volume of the Princeton Mathematical Guide, there is a saying: "Curiosity is the driving force for doing mathematical work. When will a special result be true? Is this the best proof, or is there a more natural or beautiful proof? … … If you keep asking yourself such questions, sooner or later there will be a flash of answers — — Discover the possible path of research. " "It is tempting to think of mathematics as a collection of separate branches, such as geometry, algebra, analysis, number theory and so on. Geometry is mainly an attempt to understand ‘ Space ’ The concept of algebra is to understand the art of manipulating symbols, and analysis is to contact ‘ Infinite ’ And ‘ Continuum ’ , and so on. " Sunny said.

  How to apply mathematical thinking

  The application of mathematical thinking can be described as flexible, magical and extraordinary. Its application is more reflected in how to think and solve problems in a mathematical way.

  For example, Zhou Chuan’s current research on graph data modeling and algorithm is one of the most competitive research directions. A basic idea of this research direction is to organize, model and analyze data in the form of graphs. The reporter learned that this way of thinking can be traced back to the famous problem of the Seven Bridges in Konigsberg: In the 18th century, in the suburb of Konigsberg, East Prussia, Europe, the Pregiel River crossed the city. There are two islands in the river, and there are seven bridges between the banks and the two islands. At that time, the residents in the city discussed such a question enthusiastically: how can a walker walk from one place to all seven bridges at once without repeating, and finally return to the original starting point?

  "At first glance, this question doesn’t seem too difficult. Many people want to give it a try, but no one can find the answer. At that time, Euler, a great mathematician, thought from all the failures that such a move might not exist at all. How did Euler model and analyze this problem? " Zhou Chuan explained that, in fact, the modeling tool used by Euler is "graph". In this picture, there are 4 nodes and 7 edges. Nodes represent two banks and two islands, while edges represent bridges. Euler transformed the problem of seven bridges into the problem of finding special paths on the graph. Later, through mathematical methods, he strictly proved that such a special path did not exist, which brought a satisfactory end to the Seven Bridges problem.

  Euler’s way of thinking is a very representative thinking paradigm, which still has a strong guiding significance today. Because there are often complex relationships between data entities, modeling data organization from the perspective of graph usually leads to higher analysis and mining accuracy. "For example, in the problem of ranking the importance of web pages, web pages are usually regarded as nodes in the graph and hyperlinks as edges in the graph, and Markov process in mathematics is used to describe users’ web browsing behavior on the Internet. Under the framework of this mathematical model, the problem of ranking the importance of web pages is transformed into the problem of solving the stationary distribution of the corresponding Markov process. This transformation provides a new way of thinking and a more effective solution for the problem of ranking the importance of web pages. " Zhou Chuan said.

  "When you really experience the beauty of applying mathematical thinking to solve practical problems, you will feel ‘ Mathematics is the source of natural science ’ The discussion is really incisive. " Zhang Jian said. (Economic Daily China Economic Net reporter Liang Jianwei)

"Huawei’s most leading, innovative and subversive products are coming! This is an epoch-making product that others think of but can’t do. After five years of persistence and investment, we have turned science fiction into reality. " Yu Chengdong refers to this product or Huawei’s upcoming release of the world’s first three-fold screen mass-produced mobile phone-Mate XT Extraordinary Master.

According to the official warm-up video, the back panel design of Mate XT extraordinary master mobile phone is close to that of Mate 60 RS extraordinary master. The whole module is black, surrounded by a metallic decorative frame, and a polygonal camera module is placed behind it. The back shell of the fuselage is made of plain leather, and a vertical metallic "HUAWEI ULTIMATE DESIGN" logo can be seen below the camera module.

The mass production of the extraordinary masters of Mate XT has triggered domestic mobile phone manufacturers to follow suit. Known as the "King of Africa", Chuanyin is the first Huawei to release PHANTOM ULTIMATE 2, a three-fold screen mobile phone, but this model is still a prototype. There is no public statement about when to realize global mass production.

Zhao Ming, CEO of Glory, also pointed out that Glory has a layout in technologies such as 30% discount and scroll. Although the technology is ready, the specific release time depends on the market reaction. From the supply chain, Xiaomi is developing a 30% discount mobile phone, which is expected to appear in the form of a physical model or prototype at the Mobile World Congress in February 2025.

Different from the development of large folding screen and small folding screen to multi-folding screen in China, Samsung is developing a rollable mobile phone. Korean media Business Post reported that Samsung recently applied for a patent for a rollable display for smart devices.

According to foreign media Patently Apple, Samsung applied for the patent of electronic device with rollable display in Europe, with the patent number of 20240281093. The rollable display can be simply understood as a common "rolling gate" in life. Some screens are rolled inward for storage, and larger screens are pulled out when necessary.

Compared with folding screen displays, rollable displays need higher-end technical support. Overseas media predict that commercial rollable mobile phones may not appear until after 2027 due to the high technical difficulty of rollable phones.

And considering that Samsung Galaxy Z Fold has spent 11 years from development to listing, it means that Samsung’s rollable mobile phone may have a longer time to market.

Although compared with the rollable mobile phone, the technical difficulty of the three-fold screen mobile phone is reduced and the commercialization may be higher. However, due to the disadvantages of price, after-sales price, durability, versatility, and scenes, it is still open to question whether the three-fold screen mobile phone can achieve substantial growth in the short term.

Since June 2018, Rouyu Technology has taken the lead in Huawei and Samsung, taking the lead in releasing the world’s first foldable flexible screen mobile phone FlexPai. In the following years, in addition to Apple, major mobile phone manufacturers have released related folding screen models, and the shipments of larger screen, lighter and thinner folding screen mobile phones have been increasing.

Source: Based on public information collation

Counterpoint data shows that in 2024, Q2 global folding screen mobile phone shipments increased by 48% year-on-year, and Latin America’s growth rate reached 450% due to its relatively low base. Glory Magic V2 replaced Samsung to win the title of folding screen mobile phone in Western Europe in this quarter, relying on a thinner body.

Under the high growth, it is still difficult to hide several realities of the folding screen mobile phone market: First, the problem of folding screen hinge crease still exists. On the JD.COM platform, many manufacturers’ folding screen mobile phones have bad reviews related to hinges; Second, the high maintenance cost, Huawei Pocket2 to replace the new screen price of about 3000 yuan. If the original old parts can be recovered for free, the cost will be more than 2000 yuan, which is enough for consumers to buy brand-new machines.

Third, the development path of consumer electronic products is probably as follows: manufacturers’ shipments increase → dilute manufacturers’ R&D costs and after-sales costs and supply chain manufacturers’ costs → lower prices to drive shipments increase → continue to dilute costs, and the yield rate continues to increase → continue to drive sales. The traditional large bar mobile phone has grown up according to this path.

If the folding screen mobile phone wants to realize this path, it still faces a lot of resistance. Huang Tao, vice president of vivo products, said that overcoming various technical problems requires manufacturers and suppliers to constantly promote ripening. Under the current situation that the total amount is not large enough, the overall difficulty of promoting things is relatively large.

Based on this, it is difficult for high-priced folding screens to enter the mainstream mass market and remain a niche market in the short term.

Trend Force Jibang Consulting data shows that in 2023, the global shipment of folding screen mobile phones was 15.9 million, accounting for about 1.4% of the total smartphone market. It will grow to 17.7 million in 2024, but the proportion will only increase by 1.5%.

If the above problems are put on a three-fold screen mobile phone, the problems may be more prominent. On the one hand, in order to ensure the user experience, the three-folding screen mobile phone pursues thinness more than the big folding screen and the small folding screen.

For example, when the prototype of a three-fold mobile phone is folded, the thickness of the whole machine is 11mm, which is almost close to the thickness limit of a three-fold screen mobile phone in terms of the thickness of Samsung Galaxy Z Fold 6, Huawei Mate X5 and Glory Magic V3.

In order to achieve thinness and thinness, three folding screens need to use flexible OLED screens and hinges with longer life at the same time, and demand higher yield, cost and income of supply chain manufacturers.

It is reported that Phantom Ultimate 2 prototype can be folded zigzag through two sets of hinges. Officials say that its rotating shaft can withstand up to 300,000 folds and has a high strength of 2100MPa. Huawei’s 30% mobile phone consists of a double hinge structure folded inside and outside, which requires high flexibility, durability and hinge strength of the display.

At present, the core problem of hinges is the low yield. According to the relevant research report of Shanxi Securities, the median yield of hinges in the industry is about 50%-60%, which is the biggest threshold for the assembly of folding screen panels. It is bound to be more difficult to use the three-fold mobile phone panel with double hinge structure.

In addition to the hinge problem, the chip is also a big problem. These two problems or the supply chain still have shortcomings.

Citic Construction’s related research report mentioned that the triple-folding model is a brand-new folding form, which still poses great challenges to the supply chain. If the supply chain delivery capacity cannot meet the demand, the shipment of Huawei’s triple-folding model may be less than expected.

The yield of the upstream supply chain is low and the technology is immature. Huawei needs to ensure the normal profits of dealers. The supply chain estimates that the price of Huawei’s three-fold screen may be as high as 20,000 yuan.

If you refer to the screen maintenance cost of Pocket2, the maintenance cost of the three-fold screen will only be higher. In other words, the purchase cost is superimposed on the possible maintenance cost, and the use cost of Mate XT extraordinary master is at least 20,000 yuan.

However, whether it was the hot sale of Mate60 in the market last year, the out-of-stock caused dealers and scalpers to eat, or the sales volume of Nova Flip exceeded 45,000 units in 72 hours, which increased by 85% year-on-year.

Whether the shipment of Mate X5 series is more than 4.5 times higher than that of X3, or the upcoming Mate XT Extraordinary Master takes the world’s first mass-produced three-fold screen mobile phone as a selling point, scalpers are speculating the Mate XT Extraordinary Master at a sky-high price.

On salted fish, the price of Mate XT has reached 50,000-60,000, and the price given by some sellers is as high as 100,000, and the premium rate is close to 5 times.

The extraordinary master of Mate XT, who is positioned in the ultra-high-end business market, is responsible for Huawei’s impact on the higher end. On the one hand, Huawei’s existing production capacity cannot achieve large-scale global supply, and more high-end products need to be launched to continuously improve revenue and profits; On the other hand, some dealers revealed that Huawei’s TOC business has changed from selling goods to operating customers, which means that Huawei wants to get rid of the shackles of the original stores and change from sitting in a business to a merchant. It also means that Huawei’s integrated business is also fully adjusted to high-end.

?

It is undeniable that the global mass production of Huawei MateXT three-fold screen mobile phone shows the comprehensive technical strength of Huawei and supply chain manufacturers.

According to market rumors, the panel supplier of Huawei’s three folding screens is BOE. As early as 2022, BOE has announced the successful development of F-OLED flexible N-shaped folding display technology, which can realize internal and external folding simultaneously. The water-drop folding life of inward folding R3 is 200,000 times, and that of outward folding R5 is 100,000 times.

If BOE officially supplies Huawei, the expected service life will be further improved, which means that the comprehensive technical strength of domestic panel manufacturers may be able to compete with SDC, the originator of folding screen panels.

It is still open to question whether the extraordinary master MateXT can provoke Huawei’s high-end tasks. In addition to the supply chain problem, Li Nan, president of Meizu, publicly criticized Huawei’s three-fold screen for being 10mm thick, which was not practical. And the design and technology began to pay attention to X grid instead of talking about cost performance. This is a very small number of middle-aged men who are not poor in money and have serious and advanced fun. The implication is that there are too few consumers who are willing to pay for Huawei’s Mate XT of more than 20,000 yuan.

In addition, it is urgent to answer several key questions to the market after the three-folding-screen mobile phone is really listed in a large area, which is expected to drive the manufacturers to increase their shipments and the relevant supply chain manufacturers to benefit. That is: compared with the existing consumer electronics, what is the core advantage of triple folding? Or what kind of differentiated experience can a three-fold mobile phone with a price of more than 20,000 yuan bring to consumers?

Manufacturers focus on two forms of triple-fold exposure. First, it is unfolded from the triple-fold used by Yu Chengdong in the engine room and is close to the size of a tablet computer. The message list is displayed on the left side of the screen, and other split-screen browsing contents seem to be displayed on the middle and right side of the screen. After the real launch, there may be a new design and planning in the split-screen operation, and the use scenarios of the overall equipment are expected to be more than the existing folding screen equipment.

The other is the "tent mode" under the expansion of Phantom Ultimate 2, where users can operate different pages by touching the pen. Although the overall operation is similar to that of a tablet computer, the other screen is idle.

Zhang Nan (pseudonym), a consumer from Fuyang, Anhui Province, told DoNews that he personally thought that the three-fold screen was a little tasteless, and compared with the traditional straight mobile phone, it had no advantages in maintenance cost, portability and price. Compared with tablet, the game screen is not as big as tablet, and the whole operation experience is not as good as tablet.

Compared with a business office computer, it is more expensive for me and my colleagues to get used to Apple or Microsoft’s operating system than a high-profile business office computer. Compared with the big folding screen, I don’t need it for my daily business and business socialization. If you simply meet the entertainment needs and pursue a big screen experience, why not buy a large-size TV or projector directly?

The same feeling as Zhang Nan is also Hu Yang (a pseudonym) who sells a mobile phone in Zhoukou, Henan Province. Hu Yang said that many customers he comes into contact with every day pay more attention to the configuration of mobile phones and the problem of jamming, and pay limited attention to the screen. And the core functions of consumers using mobile phones are games, payment, short videos and social interaction, and some consumers will make adjustments according to their occupation and personal habits. At present, the function of smart phones is not insufficient, but a serious surplus.

As Hu Yang said, since 2024, in addition to Apple, major mobile phone manufacturers have launched AI mobile phones. And in order to meet the needs of policy supervision, domestic mobile phones seek cooperation from overseas big models, and overseas mobile phone manufacturers seek cooperation from domestic big model manufacturers.

However, Canalys reports that consumers who pay attention to AI mobile phones can be divided into four categories: technology enthusiasts, value-maximizers, pragmatists and skeptics.

Among them, pragmatists account for the largest proportion of 67.9%. At present, the real AI mobile phone buyers on the market are technology enthusiasts. It is estimated that the market will wait until 2025 or 2026, and those who pursue value maximization and pragmatists will pay for AI mobile phones, and the relevant supply chains will also target this group in advance.

Based on this, AI mobile phones currently have limited contribution to manufacturers’ shipments. According to Canalys data, global smartphone shipments in Q2 in 2024 only increased by 5% year-on-year, and most of them were contributed by markets in Eastern Europe, Southeast Asia and Latin America. If manufacturers continue to lower the price of AI mobile phones in order to hedge the research and development costs of AI big models, this means that it is difficult for three-fold screen mobile phones to sell AI.

In addition, with the consumer market paying more and more attention to the comprehensive cost performance, it is also difficult for the extraordinary masters of Mate XT to replicate the sales myths of Mate60, Nova Flip and Mate X5. Although the shortage of Mate60 provided the basis for the hot sales in the early stage of Pura 70, on the day of Pura 70 sales, the real-time search popularity of Meituan flash purchase directly increased by over 3600%. Cattle is a premium of 2000 yuan, and some popular colors are not available from stock.

However, if Pura 70 is put into a mobile phone with the same price, its overall cost-effective advantage is slightly insufficient compared with competing products. Based on this, the popularity of Pura 70 did not last long. Since July, its price has been reduced several times. With the increasing number of three-fold screen mobile phones sold by manufacturers in the future, what are the differentiated selling points that can be recognized by consumers? This is worth pondering by all manufacturers.

At present, mobile phone manufacturers are constantly rolling up big folds, small folds and triple folds, but traditional straight mobile phones still face many practical challenges if they want to grow more.

First, the problem of battery life. Zhang Wei (a pseudonym), a freight driver who has been engaged for many years, told us that the navigation function needs to be turned on during the whole process of the truck driver’s sports car, which requires high battery life of the mobile phone. In recent years, although many manufacturers of flagship machine have been purchased, the overall endurance is not good. After three or four hours of navigation, the power will soon drop from 80% to 20%. To make matters worse, in the hot summer, smartphones are not only slow, but sometimes they can’t be charged. Not only Android, but also the difficulty of low-temperature apples in winter has been criticized by many Apple users.

The second is the stuck problem of traditional straight board machine. According to the data of China Information and Communication Research Institute, in July this year, Apple’s market share in China has fallen to single-digit level, and the comprehensive proportion of Android mobile phone manufacturers has reached 90%.

However, Rong Qiang (a pseudonym), a salesman from an Apple store in Fuyang, Anhui Province, told us that many of the customers they come into daily contact with are because the Apple operating system is smoother than Android phones and is not stuck. Many old Apple users are not used to the Android operating system, or after using Android phones for a period of time, they continue to buy Apple. Even old Apple users who are highly concerned about cost performance will ask if there is an Apple II mobile phone in the store.

As Rong Qiang said, whether the black cat complaint involves the stuck Android phone, or the bad reviews of many manufacturers on the JD.COM platform can always see the stuck problem, or the second Apple phone accounts for a relatively large proportion, all of which explain the stuck problem or the problems that need to be solved and optimized constantly at present.

The third is the price issue that consumers are quite concerned about. With the increasingly fierce price war between JD.COM and Tmall, it is continuously impacting the price system of mobile phone manufacturers. Take this year’s 618 as an example. Starting from 0: 00 on May 20th, JD.COM successively removed the popular products of Redmi Turbo3 and K series for nearly five hours. In addition, several categories of mobile phone brands, such as OPPO, vivo, iQOO, Yijia and Glory, were also dropped by JD.COM.

The cause of the incident is that JD.COM and Tmall adopted the same price strategy. However, in order to expand the market share of 3C, Tmall added 100 yuan to the 88VIP discount on the basis of the original discount. JD.COM is a price-chasing Tmall, and under the business keys emphasized by Liu Qiangdong, such as improving efficiency, reducing costs and increasing efficiency, and focusing on pragmatism, mobile phone manufacturers are required to bear the subsidy price. Under the game between the two sides, the manufacturer’s model will be temporarily removed.

However, consumers will not pay attention to the tripartite game between JD.COM, Tmall and the brand, and the price reduction will still cause a lot of consumers’ dissatisfaction with backstab. On the black cat complaint platform, there are more than 4,000 complaints about the price reduction of mobile phones, covering multiple mobile phone brands. In other words, how to achieve a balance among channels, profits and consumer interests protection is one of the problems faced by brands.

Not only in the domestic market, India is regarded as one of the important growth markets overseas. Although the high temperature and rising prices have caused the demand in the Indian mobile phone market to stagnate, Counterpoint data shows that in the first half of 2024, India’s mobile phone shipments increased by 7.2% year-on-year to 69 million.

Although the average selling price has risen, consumer demand has continued to stagnate, but from January to June 2024, India’s smartphone shipments still reached an annual growth rate. Small-scale long-tail brands such as iQOO, Motorola, Nothing, and Poco, an independent brand of Xiaomi, have become the main kinetic energy to push up India’s annual growth rate for four consecutive quarters.

But whether India violated some visa regulations with Vivo and claimed to steal $13 billion from India. Either India has previously frozen Xiaomi’s assets of more than 600 million US dollars, or the Indian government’s procurement of GPU only allows domestic registered operators to bid, all of which indicate that domestic mobile phone manufacturers still need to break through many obstacles if they want to truly survive, gain a foothold and achieve greater growth in India.

There is nothing wrong with manufacturers’ rolling technology, and the process of rolling each other can also lower product prices and enhance domestic technical strength. However, if manufacturers want to rely on the three-fold screen to drive the sales explosion, there may be many problems to be solved.

International observation: Russian economy meets challenges in recovery

    Xinhua News Agency, Moscow, January 7th Title: Russian economy meets challenges in recovery.

    Xinhua News Agency reporter Huang He

    Although the impact of the Ukrainian crisis and western sanctions on Russia continues, the Russian economy as a whole showed a recovery momentum in 2023, and the economic growth rate exceeded the expectations of the Russian government and many international institutions. But at the same time, the Russian economy has also exposed some problems and challenges. Analysts predict that the Russian government may take measures this year to promote balanced industrial development, improve production efficiency, and implement a relatively tight monetary policy to curb inflation and promote sustained economic growth.

   Triple factors help economic recovery

    In 2023, the Russian economy showed a recovery momentum. Russian President Vladimir Putin recently summed up the situation of Russia’s economic development in 2023 in the face of the "annual inventory" activities of the media and the public, saying that compared with the 2.1% contraction of gross domestic product (GDP) in 2022, Russia’s GDP is expected to increase by 3.5% in 2023.

    Putin said that in 2023, Russian industrial production is expected to increase by 3.6%, manufacturing industry by 7.5% and investment in fixed assets by 10%. At the same time, the profits of Russian enterprises are expected to increase by 24%, and the wage income of residents is expected to increase by 8%.

    Nikyshina, general manager of the Russian Export Center, told Xinhua that Russia has successfully overcome the pressure of sanctions imposed by the West since last year, and the goal of "the West hopes to crush Russia’s economy and crowd Russia out of the international trade chain through sanctions" has not been realized. "Russia has not been isolated from international trade, but is a very active participant in the world market."

    Analysts believe that Russia’s economic growth last year benefited from three aspects. First of all, the relatively stable export income of energy and grain, and the improvement of manufacturing and consumption have provided support for economic growth. The relatively stable export income of energy and grain is an important factor to promote Russian economic growth. At the same time, Russian official data show that about one-third of Russia’s economic growth in 2023 comes from the military-industrial complex and related electronics, computers, optics and other industries.

    Second, financial control measures have been effective. Since last summer, the ruble has been depreciating, and the exchange rate of the US dollar against the ruble has repeatedly exceeded 1 to 100. In this regard, Russia has introduced strict control measures, requiring some export enterprises to carry forward foreign exchange income in the domestic market, and strengthening financial supervision of related enterprises to reduce the volatility of the ruble by regulating foreign exchange liquidity.

    Moreover, Russia has broken through the western blockade in international trade. Since 2023, on the one hand, Russia has vigorously developed trade with "friendly countries", on the other hand, it has actively promoted the use of local currency in international settlement. Russian Prime Minister Dmitry Mishustin said that the trade volume between Russia and "friendly countries" is increasing rapidly in Russia’s total foreign trade. In addition, by the end of 2023, the share of local currency settlement between Russia and other countries is expected to reach 65%.

   Multiple challenges constrain sustained growth

    Russia still faces many risks and challenges to achieve sustained growth. Analysts pointed out that in addition to external sanctions, the Russian economy also faces challenges such as industrial imbalance, inflationary pressure and labor shortage.

    On the one hand, the growth model driven by military production may be difficult to sustain. Last year, the Russian military’s industrial production increased substantially, but the production of civilian products requiring complex technological processing capacity decreased significantly. Analysts believe that the current economic growth model that relies too much on military production is not only unsustainable, but may even further push up inflation.

    On the other hand, the pressure of stabilizing prices, ensuring supply and reducing inflation continues to increase. According to the reporter’s observation, in big cities such as Moscow and St. Petersburg, the supply of fruits, vegetables and meat is still tight or the prices have risen sharply. In order to curb inflation, the Russian central bank recently raised the benchmark interest rate to 16%. Nabiulina, governor of the Russian central bank, said that the fundamental reason for the high inflation is that the current production cannot immediately meet the growing demand.

    Moreover, the shortage of labor will also restrict the sustainable economic growth. At present, the unemployment rate in Russia is at an all-time low of 2.9%. According to "Russian newspaper", the current employment gap in Russian manufacturing industry is 660,000, and the employment gap in agriculture is 200,000. Berenikaya, a macroeconomic analyst at the Russian investment company, said that the labor shortage is related to Russia’s long-standing population problem, as well as the impact of special military operations and national defense production on the labor market.

   Multiple measures to stabilize economic operation

    Considering that many unfavorable factors may inhibit the economic growth momentum, Russia’s economic growth rate may slow down this year. The Russian central bank predicts that the Russian economic growth rate will be between 0.5% and 1.5% in 2024.

    Analysts predict that the focus of the Russian government’s economic policy in 2024 will be to promote balanced industrial development, improve production efficiency, and at the same time cooperate with relatively tight monetary policy to curb inflation. In order to promote economic growth, in 2024, the Russian government is expected to increase efforts to support enterprises to invest in production, develop new technologies and strengthen personnel training.

    Maxim Oreshkin, adviser to the Russian President, said that improving the level of production automation is one of the top priorities of the Russian government in the future, and "high-quality talents and automation are two key factors that determine the long-term development level of the Russian economy".

    The Russian central bank recently predicted that by the end of 2023, Russia’s inflation level will be between 7% and 7.5%, far exceeding the target level of 4%. The Russian government hopes that the inflation rate will fall back to 4% to 4.5% by the end of 2024. Nabiulina said, "This means that we will maintain a tight monetary policy for a long time to come."

[Advance new goals, write a new chapter] Innovation has become a trend, from "following" to "leading" Shenzhen relies on what?

  CCTV News(Reporter, Wang Xiaoying) In 2012, the General Secretary of the Supreme Leader visited Tencent and emphasized: "The Internet era has greatly promoted the development of human life, production and productivity."

  At that time, the General Secretary of the Supreme Leader also visited the Guangqi Institute of Advanced Technology, and President Liu Ruopeng promised the General Secretary: "We must be a world-class innovative enterprise in metamaterial innovation technology.

  On the occasion of the fifth anniversary of the Supreme Leader’s visit to Guangdong, on November 28, the Supreme Leader’s General Secretary’s visit to Guangdong’s fifth anniversary all-media interview activity walked into Tencent and Guangqi to learn about their innovation stories in the past five years and explore the secret of Shenzhen’s journey from "following" to "leading" on the road of innovation.

  Tencent: WeChat has been the top social software in China for five years

Tencent innovation chronology

  The world’s first commercial and practical jetpack "Guangqi Martin Flight Bag", the "Cloud", an aerial residence platform that integrates communication, optical remote sensing, Internet of Things monitoring, big data collection and analysis, and the subversive low-cost "green" transportation platform "Sun Ark"… These amazing "black technologies" all originated from Guangqi Institute of Advanced Technology (hereinafter referred to as "Guangqi").

  Since its establishment in 2010, Guangqi has developed from a 5-person returnee innovation team to a global innovation group with a R & D team of nearly 2,600 people, a global innovation community, technical personnel across 5 continents, innovation institutions are distributed in 21 countries and regions, the pace of marketization continues to expand, and the technical application field has expanded from the field of metamaterials to aerospace and artificial intelligence.

  As of November 2017, Guangqi’s patent applications exceeded 4,400, nearly double that of five years ago, and more than 2,400 patents were authorized. Among them, patents in the field of metamaterials have an overwhelming advantage, accounting for 86% of the total number of patent applications in this field. It has mastered the world’s leading metamaterial technology, new space technology and intelligent photonic technology, and other core intellectual property rights, leading the way in international competitiveness.

  "Young members bring new ideas and vitality to the team. Guangqi can recruit outstanding talents from top foreign universities. In addition to recognizing the company’s innovation and technology, it also depends on Shenzhen’s generous policy of attracting talents and the environment of innovation and entrepreneurship in Shenzhen." Yang Jingru, brand director of the Brand and Market Operation Center of Shenzhen Guangqi Institute of Advanced Technology, told reporters that for this company, which specializes in "future" products, one of the biggest "troubles" is to explore the confusion or pain points in the city, convert market demand into technical demand, better connect with market demand, and integrate innovative technology into the daily life of citizens.

  Global Talent Strategy Boosts Innovation

  Nowadays, building a modern, international and innovative city has become the new mission of the special zone.

  The leapfrog development of Tencent and Guangqi stems from innovation and is also the epitome of the innovative development of tens of thousands of enterprises in Shenzhen. In 2016, Shenzhen’s high-tech industry achieved an output value of 1.922206 trillion yuan and an added value of 656.002 billion yuan.

  Innovation-driven, talent first. The essence of innovation-driven is talent-driven. Whoever has first-class innovative talents will have the advantage and dominance of technological innovation.

Li Xiaogan, member of the Standing Committee of the Shenzhen Municipal Party Committee and Minister of Propaganda Department

Li Xiaogan, member of the Standing Committee of the Shenzhen Municipal Party Committee and Minister of Propaganda Department

  Li Xiaogan, member of the Standing Committee of the Shenzhen Municipal Party Committee and Minister of Propaganda, said that in 2016, Shenzhen launched several measures to promote scientific and technological innovation, support enterprises to enhance competitiveness and promote the priority development of talents, and guided by three policies to further promote supply-side structural reform. The reform released strong momentum. In 2016, Shenzhen’s GDP exceeded 1.93 trillion yuan, an increase of about 9% year-on-year.

  In order to attract talents, Shenzhen implements the "Peacock Plan", which arranges 1 billion yuan per year to introduce overseas high-level innovative talent teams, with a maximum subsidy of 100 million yuan. A talent innovation and entrepreneurship fund with a total scale of 8 billion yuan is established to support talents to carry out research on cutting-edge technologies, original technologies, and disruptive technologies. For example, Royole Technology, founded by Liu Zihong’s team introduced through the "Peacock Plan", has successfully developed the world’s thinnest color flexible display screen, which is less than 1/5 the diameter of a hair strand. It has been among the "Unicorn Club" with a global valuation of over 1 billion US dollars for more than two years.

  At the same time, in the past five years, Shenzhen’s total social R & D investment has increased from 3.77% of GDP in 2012 to 4.1% in 2016, realizing the transformation of technological innovation from "follow-up" to "parallel-run" and "lead".

  Shenzhen has formulated the country’s first national innovative city master plan, taken the lead in issuing local regulations to promote scientific and technological innovation, and successively issued a series of policies such as "33" independent innovation, "1 + 10" documents for innovation-driven development, strategic emerging industries, and future industrial planning. It has comprehensively increased support for independent innovation from various aspects such as financial and financial support, talent support, innovation carrier construction, and the development of science and technology service industries, forming a policy chain covering the entire process of the independent innovation system.
