Do batteries need to keep warm in winter？ Let’s take a look at the battery technology that will ＂self-heat＂

　　[Pacific Auto Network] Since humans began to use electricity, anxiety about the use of electricity has always existed. Even the appearance of batteries for storing electric energy only slightly eased this anxiety. Just like the hot electric car in the world now, even if there is a fresh experience, it is still impossible to avoid the anxiety caused by battery life.

　　The direct impact of batteries on electric vehicles has also made major new energy sources and battery supplies rack their brains to promote ways to increase battery life. However, whether it is the physical battery stacking scheme, the method of changing the electrolyte composition or even the material form of the battery, the battery life can’t even show a normal state in the face of low temperature. How to keep the battery warm and warm at low temperature has become the key to fight against this "battery killer".

　　In the process of developing and using the battery, we already know that the battery has a normal working temperature range, and the actual use effect of the battery will be greatly reduced in a low temperature environment, so the battery needs a good thermal management to keep it warm in this environment.

　　On April 21st, Changan Deep Blue Brand, a subsidiary of Changan Automobile, held a deep blue technology sharing meeting, at which an item named "Micronucleus High Frequency Pulse Heating Technology" was announced.

　　Just listening to this name, we know that this technology is definitely aimed at the battery thermal management system, especially the word pulse heating exists. Looking back at the technology announced by Chang ‘an this time, in fact, its idea is not complicated. Under the condition of constant heating, let the battery pack heat up more quickly and evenly, so that the battery pack can reach a suitable working environment at low temperature as soon as possible.


Contemporary Amperex Technology Co., Limited patent CN 108711662 B pulse heating device

　　In principle, it is actually based on a patented technology published by Contemporary Amperex Technology Co., Limited. This patent takes advantage of the characteristic that the internal resistance increases due to low temperature. By installing devices that can generate oscillating current at both ends of the battery, the current passes through the battery cells with large internal resistance, so that a lot of heat is generated inside the battery, and finally the battery temperature rises rapidly.

　　Although this heating method can make Contemporary Amperex Technology Co., Limited’s battery pack reach the heating efficiency of 4℃/min, it is easy for the lithium ions in the lithium battery to form dendritic metallic lithium in the process of reduction on the negative electrode, that is, "lithium dendrites". The growth of "lithium dendrite" to a certain extent will affect it slightly, and it will cause internal short circuit of lithium battery, which will seriously threaten personal safety.

　　Therefore, in order to avoid lithium dendrites on the negative electrode of the battery due to frequent over-charging, Changan slightly improved this technology based on Contemporary Amperex Technology Co., Limited’s technology, and chose to use alternating current to generate current for heating the battery pack.

　　Why do you have to mention alternating current? In the previous battery self-heating technology, the current generated was DC. According to the physical definition, the current whose magnitude and direction do not change in unit time is called direct current. Looking back at the conditions for the generation of "lithium dendrites", it is too late for the negative electrode to treat lithium ions during the discharge process, resulting in the appearance of metallic lithium.

　　The negative electrode of the battery that needs breathing time is easy to reach the limit in the face of constant output of direct current, and then it is easy to appear "lithium dendrite". Therefore, in order to weaken this "invariability", it is necessary to give the negative electrode some breathing space, and alternating current with periodic changes in the magnitude and direction of current per unit time is more suitable for this work.

　　Unlike direct current, alternating current does not always keep a constant value, but it always keeps a periodic change of positive value -0- negative value -0- positive value. It is precisely because of this unsteady characteristic of alternating current that the burden on the negative electrode of the battery can be reduced, thus reducing the probability of lithium dendrites.

　　At the same time, Chang ‘an also mentioned the semiconductor IGBT (insulated gate bipolar transistor) at the meeting. IGBT is a switch that is either on or off. It has no function of amplifying voltage. When it is on, it can be regarded as a conductor, and when it is off, it can be regarded as an open circuit. Coupled with the cooperation of the motor and BMS system, random high-frequency current charging and discharging switching can be realized, which further reduces the occurrence of lithium dendrite.

　　The dark blue C385 power battery pack officially announced by Chang ‘an can keep the heating rate of 4℃/ at the ambient temperature of minus 30℃, and can improve the power performance by 50% and shorten the charging time by 15% at the ambient temperature of minus 30℃. From the data point of view, the improved "battery self-heating" technology is not only more efficient, but also has a longer battery life, which is quite good news for users in low temperature areas.

　　At present, the mainstream types of batteries on the market can be divided into two types according to the element types, namely ternary lithium batteries and lithium iron phosphate batteries. The biggest difference between them is the different cathode materials used.

　　Lithium iron phosphate battery uses Ferrous lithium phosphate (PO4) as cathode material. Its advantage is that it is very safe at high temperature or overcharge, but its disadvantage is that at low temperature (below -10℃), the lithium phosphate battery decays very quickly. After less than 100 charge and discharge cycles, the battery capacity will drop to 20% of the initial capacity, which is basically insulated from the use in cold areas.

　　Ternary lithium batteries are lithium batteries made of lithium nickel cobalt manganate (Li(NiCoMn)O2, NCM) or lithium nickel cobalt aluminate (NCA). Nickel salt, cobalt salt and manganese salt are adjusted in different proportions, so they are called "ternary". For example, NCM811 in Contemporary Amperex Technology Co., Limited means that the ratio of nickel, cobalt and manganese is 8:1:1.

　　The advantage of ternary lithium battery is its high energy density, both of which are made in Contemporary Amperex Technology Co., Limited. The energy density of its lithium iron phosphate battery is 178Wh/kg, while that of NCM523 is 200Wh/kg and that of NCM811 is 240Wh/kg. In terms of low temperature, ternary lithium battery can also maintain normal battery capacity at -30℃, which is more suitable for the use conditions in the northern low temperature area. The disadvantage is that the ternary material of ternary lithium battery will decompose at 200℃ at high temperature, and it is easy to burn or explode at high temperature.

　　Although the materials, advantages and disadvantages of the above two batteries are different, from a microscopic point of view, their working principles are also the process of lithium ion migration back and forth between the positive and negative electrodes.

　　In the low temperature environment, the activity of the anode and cathode materials of the battery decreases, and the conductivity of the electrolyte as a bridge also decreases. Therefore, when the battery is charged and discharged, there will be resistance inside, which is called internal resistance. When the internal resistance of the battery increases, during the normal use of the battery, a lot of Joule heat will be generated to cause the battery temperature to rise. Experiments show that when the environment is below 0℃, the internal resistance will increase by about 15% for every 10℃ drop in temperature.

　　Being hindered by internal resistance, trying to exert force can only lead to excessive discharge of the battery, and the electric energy is continuously converted into heat energy, which not only reduces the power, can’t output power normally, but also easily affects the safety of the battery. All these results are caused by the low temperature environment.

　　In order to solve this problem, in addition to the latest "pulse self-heating" technology mentioned above, in fact, suppliers and manufacturers have done a lot of "warm" measures.


PTC element


Heating film

　　At present, there are several common schemes. The first one is PTC and heating film selected by most pure electric vehicles. The idea of this scheme is to heat the battery through external electric heating elements to improve the battery temperature. There are two kinds of PTC: water heating and air heating. Water heating heats the coolant through PTC and then exchanges heat with radiator. Air heating means that after the warm air is turned on, the cold air directly exchanges heat with PTC and finally blows out warm air. The heating film is like covering the battery with a conductive heating quilt, but both of them have obvious shortcomings. PTC is easy to cause uneven heating and occupy the space of the battery compartment. Because of the safety, the overall cost of the heating film is not low, and the actual heating efficiency is not high.

　　Another scheme is the liquid cooling circulation system, which is like adding a set of heating to the battery pack, and heating the coolant to obtain a long-term heat source. Another scheme is heat pump air conditioning. The whole principle is like the forced extraction of atmospheric heat into the car, but when the ambient temperature is too low, the heat pump is easy to fail, so a "magic change" is also made, which not only extracts the heat from the outside air, but also collects the waste heat generated by the power battery system, the drive system and the PCS power electronics. The whole system relies on the eight-way reversing valve for complex heat extraction, so as to improve the overall efficiency of the heat pump air conditioning.

Bai Aihua, a paper-binding artist： Creating a Wonderful World with Skillful Hands

As a unique folk culture in China, paper binding has been passed down for more than a thousand years. From generation to generation, the art of paper binding has absorbed a variety of cultural forms and presented a heavy humanistic force.

Bai Aihua, a paper-making artist, is the inheritor of Yuzhong Paper-making, an intangible cultural heritage in Lanzhou. The paper-making skills she inherited from her father Bai Ruhe have brought too many good memories to the lantern viewers. A moth eyebrow draws a smile, a small mouth cuts out a god, and the ecstasy of each character is between a stroke and a cut of white love flowers.

When it comes to the relationship between the White House and the art of paper binding, we should go back to 1939. That year, Bai Ruhe, who was only 16 years old in Baibao Village, Ma Po Township, Yuzhong County, came to Agan Town to be an apprentice under the name of a well-known stone painter. Speaking of this stone painter, the hearts of the descendants of the White House are always full of worship and admiration. It is said that the ancestors of stone painters painted with lanterns, and the reason why the stone family made a name for itself in Lanzhou was that it was praised for tying lanterns for the Suwangfu, and many years later, the lanterns for the Suwangfu had the contribution of the stone family. This craft has been accumulated and passed down from generation to generation by the Shi family, and it has been completed by Master Bai Ruhe.

Bai Ruhe was worshipped by the stone painter at that time. Although he was only a small apprentice, he was diligent and talented, and then he gradually stood out among many apprentices and won the favor of stone painters. In addition, the stone painter’s family was thin, and the old man finally chose to pass on the paper binding skills to Bai Ruhe without reservation. And Bai Aihua is the youngest daughter as white as a lotus. She said that her father taught her very strictly at the beginning, and a little bit of disqualification had to be reinvented. Nowadays, Bai Aihua, as a non-genetic inheritor, has completely inherited his father’s talent and wisdom in this respect.

Although the appearance of the huge lantern group of modern lanterns makes some small lanterns lose their former luster, the ingenuity of traditional craftsmen has its own uniqueness. Take the binding of characters as an example. Eyebrows are just the finishing touch of paper binding works, among which there are many doorways to shine. On the operating platform of Baiaihua, the superior bamboo is neatly processed, and the length, width and thickness are strictly required. Even if the small bamboo joints are finely polished, it is afraid that the appearance will be affected if there is any protrusion in the binding process. Compared with modern paper lanterns, the pigments of traditional lanterns are superior. Minerals such as azurite, azurite and cinnabar can only be used as pigments after careful grinding, and they will not fade easily even if they are placed outside in the wind and sun.

Today, what makes Bai Aihua feel the most beautiful is the Lantern Festival in Yuzhong County in 1992. In that exhibition, her and her father’s tied products won the grand prize, and their vivid shapes attracted many audiences. Two hand-tied lambs actually attracted real sheep with fake ones.

Bai Aihua said that although modern civilization will have an impact on traditional craftsmen, the yellowed paintings will never disappoint the craftsmen who love it. The manuscripts accumulated by craftsmen from generation to generation are a general history of folk customs and deserve to be treasured forever. Regarding how to make the paper-binding skills glow with new vitality in the inheritance, Bai Aihua said that the inheritance should first be passed down with serious skills, and the technological process should not be changed just to please, so the so-called inheritance may not exist. However, we should also make bold innovations in inheritance, which can spark better innovation in generate when it reaches my son’s generation. For me, keeping the skills left by my ancestors completely is the best contribution to the intangible heritage.

Amazing! Record the whole process of recycling mobile phones in Huaqiang North.

　　There are 889 million people holding mobile phones in China, and this amazing data has undoubtedly pushed China to the top of the world in terms of the number of mobile phone users. In Chinese, a mobile phone is replaced every 15 months on average, but most of the old mobile phones are discarded at will, and only 1% of the old mobile phones are recycled.

The whole process of recycling used mobile phones in Huaqiang North

　　Once discarded, discarded mobile phones, mobile phone batteries and charging equipment will contain a lot of harmful substances such as nickel and cobalt, which will cause great pollution to water and soil, and will cause hundreds of thousands of tons of electronic waste, which will inevitably lead to a great crisis of treatment. The pollution scale is much larger than that of other discarded electronic products such as discarded computers and color TVs. How to recycle and dispose of them has become a major environmental protection issue facing China.

　　In order to change this waste of resources, Nokia launched a program called "Green Box" in 2005, which placed collection boxes in more than 700 Nokia customer service centers and specialty stores in more than 300 cities for recycling used mobile phones. However, the number of recycled mobile phones is still very small, so where do the remaining discarded mobile phones flow?

　　David Kousemaker, a Dutch designer, arrived in Huaqiang North, Shenzhen, Guangdong Province, where he saw the scene of mobile phones being traded as raw materials and took the following photos. He wrote in his blog Tech Travels:

　　There are two tall buildings in a hidden corner of Huaqiang North Business District, where people are mainly engaged in mobile phone recycling. An entrepreneur told me that he bought these mobile phones in bulk from a wholesaler, who mainly picked up used mobile phones from garbage dumps in Hong Kong and another major Asian city.

　　Outside the building, I saw a man sorting out bags of mobile phone chips. I don’t know what he wants to do, but I guess someone wants to buy a mobile phone and he is looking for a matching mobile phone chip.

　　The plastic casings of used mobile phones will also be dismantled. Although we can’t get much oil and water from these casings, because the labor force in China is low, it can also be profitable to hire workers to dismantle the metal objects on the plastic casings.

　　Then someone will take down the components on the chip and pick, sort and classify them.

　　Next, they will remove the flux and solder from the component pins and further classify them. This is the most important step for many shops that renovate their mobile phones. But a little unexpectedly, this work is mostly done by girls and young women.

　　Some components are so small that they can only be operated with tweezers.

　　Foreign netizens think that China’s seriousness in recycling electronic waste is shocking, while other countries are not very concerned about it. They think it’s time to cheer and applaud China’s behavior. Of course, some people doubt the truth of this matter, and a little thoughtful ask: What are these recycled components used for later? Although some people also leave a message explaining that Huaqiang North Business District is a second-hand mobile phone market, it seems that they can’t resist the admiration of other netizens for China.

　　The practice that used mobile phones are refurbished by second-hand vendors and then sold is never the right way out. Parts and shells that lose value during the refurbishment of used mobile phones will be discarded by vendors at will, and some small workshops of used mobile phones will extract precious metals in the open air, which will directly dump the residual liquid and cause secondary pollution to the environment.

　　Since 2011, China has officially implemented the Regulations on the Management of Recycling of Waste Electrical and Electronic Products, covering refrigerators, televisions, washing machines, air conditioners and computers, but mobile phones are not yet listed. The scientific disposal of used mobile phones must be supported by policies. In China, the government, society and enterprises can jointly establish a recycling mechanism for used mobile phones and establish manufacturers — Two normal recycling modes: operators and municipalities. Relevant laws and regulations should list the behaviors that should be prohibited in the process of recycling discarded mobile phones and accessories, and clarify the legal responsibilities of related illegal behaviors. At the same time, the state supports qualified pollution-free recycling enterprises of electronic waste in terms of policies and taxes to engage in the recycling and disposal of discarded mobile phones and accessories. At the same time, it encourages major mobile phone manufacturers and related enterprises to jointly finance and establish professional mobile phone recycling companies.

A drop of perfume makes water ＂sesame oil＂？ This additive may have flowed into some restaurants.

滴几滴芝麻油香精到普通调和油中，调和油也散发出芝
Drop a few drops of sesame oil essence into the common blended oil, and the blended oil also emits the fragrance of sesame oil.


　　
The ingredient list of sesame oil essence makes people unable to understand the ingredients inside.


　　
A drop of sesame oil essence can make 380 ml of mineral water give off the fragrance of sesame oil.


[clue]


　　Ms. Wu, a citizen, called our hotline 968820, saying that when she bought cold dishes at a roadside stall, she suspected that the hawker added the problem "sesame oil"; Many roadside stalls have such "sesame oil" and use it to "enhance fragrance"


[breaking news]


　　According to people familiar with the industry, illegal traders probably used essence, mixed with common edible oil and blended "sesame oil without a sesame seed"! What’s even more amazing is: in fact, only a little "sesame oil essence" is needed to adjust the flavor of sesame oil to water; With the addition of colorants and thickeners, the blended oil can be turned into sesame oil, as the saying goes, "oil is mixed with oil, and the gods are hard to distinguish"!


[verification]


　　The reporter bought a bottle of "sesame oil essence", squeezed a drop of "essence" into the water, and then shook the water mixed with essence evenly, and a fragrance of sesame oil came to the nose; The reporter took a cup for drinking tea, poured tasteless blended oil, and then dropped a few drops of "essence" to stir. The blended oil smelled almost the same as sesame oil.


　　A drop of perfume can turn a bottle of water into "sesame oil", which is not Liu Qian’s magic. An unusual discovery made Ms. Wu, a citizen, call our hotline 968820; The reporter’s investigation found that a suspicious "sesame oil essence" frequently appeared in the Xiamen market. According to industry insiders, this additive, which can turn a bottle of water into "sesame oil" with only one drop, may flow into some illegal restaurants or roadside food stalls.


[Citizen’s reflection]


Roadside vendors add "sesame oil" to cold dishes


　　The night before yesterday, Ms. Wu bought a catty of cold dishes at a roadside stall near Taihe Garden, ready to serve wine to her friends; However, when the vendor cut the cold dish and put it into the pot to mix the seasoning, Ms. Wu saw the vendor take out a plastic bottle and add a dark oily water to the pot.


　　Ms Wu asked the vendor what it was, and the vendor explained that it was "sesame oil", that is, "sesame oil". Seeing the vendor squeezing the bottle and adding a lot, Ms. Wu couldn’t help smelling it and found that it did have a strong sesame oil fragrance. Ms. Wu has some doubts: if you buy a bottle of 400 ml sesame oil in the supermarket, you will get more than 20 yuan. According to the "addition" of the hawker, how much sesame oil you have to use in one night, isn’t it a loss?


　　Ms. Wu took a closer look and saw that the sesame oil squeezed by the hawker was a bit thin and thicker than water; There is no oil trace of "hanging the bottle" on the small hole of the bottle mouth. Now, her doubts are even heavier: is this really sesame oil? Ms. Wu didn’t dare to eat too much cold dishes. She felt that there was something wrong with the vendor’s sesame oil, so she reflected this situation to our reporter.


　　The reporter came to the location reflected by Ms. Wu and did not see the cold dish vendor she said; However, other vendors selling string incense, fried tofu and cold rice noodles nearby are also putting condiments and plastic bottles filled with "sesame oil".


[Industry News]


450ml sesame oil is 9 yuan?


　　"Sesame oil" is usually used as a condiment. Everyone likes to add some "Titian" when eating cold dishes. It can be smelled in the cucumber, bean sprouts and lettuce sold in restaurants. Especially when eating hot pot, sesame oil is also the best dipping sauce seasoning. In addition, sesame oil is essential in the cooking of hot dishes such as chicken with sesame oil and kidney with sesame oil.


　　Then, is there really a problem with the "suspicious sesame oil" discovered by Ms. Wu? Recently, a report from foreign media caught the attention of reporters: According to the report, the cost of 0.5 kg of pure sesame is higher than that of 18 yuan, but the price of bulk sesame oil flowing into farmers’ markets and restaurants is cheaper than that of sesame, and even the ultra-low price of 0.5 kg of 9 yuan appears. It is understood that sesame oil is limited by the production process, and more than 1 kg of high-quality sesame seeds can produce 0.5 kg of sesame oil. Therefore, ultra-low-priced sesame oil is very suspicious.


　　Insiders pointed out that unscrupulous traders probably used essence, mixed with common edible oil and blended "sesame oil without a sesame seed"!


　　Under the guidance of a restaurant operator who asked not to be named, the reporter visited the Jiangtou market and found two kinds of "sesame oil essence" in two condiment stores. Both of them are packed in 500 ml, one costs more than 40 yuan and the other is more than 20 yuan. The owner of another store said that the "sesame oil essence" in their store has been sold out of stock and has not yet entered new goods. "It sells more in winter." Seeing the reporter pretending to be a customer, the owner of the store told his speculation, "Are you from the hotel?"


　　In addition to "essence", the reporter also consulted the price of sesame oil. The reporter saw that a glass bottle of 450ml sesame oil, produced by an Anhui manufacturer, had a retail price as long as 9 yuan. The whole bottle of oil looked blue in color, and it didn’t have the sticky feeling of normal sesame oil when flowing.


　　The reporter then visited the Lotus Village and Market. The merchant said that the cheap bulk sesame oil is "better than the worst quality" for every 0.5 kg of 20 yuan money! The merchant seems to have something to say, but he didn’t show the oil to the reporter.


[Reporter’s investigation]


A drop of perfume turns water into "sesame oil"
The smell of "oil mixed with oil" is difficult to distinguish


　　The above-mentioned catering industry told the reporter an amazing news: in addition to adding "essence" to ordinary edible oil and then coloring it to produce "sesame oil", in fact, only a little "sesame oil essence" can be used to adjust the taste of sesame oil!


　　To test what people in the industry said, the reporter bought a bottle of "sesame oil essence" produced by a factory in Chengdu. Open this bottle of essence, and before the tin foil paper on it is opened, a strong fragrance of sesame oil comes to the nose, but compared with some brands of sesame oil, it is less astringent and just pure fragrance.


　　The reporter poked a small hole in the sealed tin foil paper with a needle, brought a bottle of 380 ml of mineral water, squeezed a drop of "essence" from the small hole, and then shook the water mixed with essence evenly, and the fragrance of sesame oil rushed out immediately.


　　The reporter also brought a cup for drinking tea, poured tasteless blended oil, and then dropped a few drops of "essence" to stir. The blended oil smelled almost the same as sesame oil, but the color was lighter than sesame oil. An unsuspecting colleague smelled this essence, saying that it was very similar to the taste of hot pot restaurants and restaurants, and only used the sense of smell to distinguish it. It was definitely sesame oil.


　　"With the addition of colorants and thickeners, blended oil can become sesame oil, which is the so-called’ oil mixed with oil, the fairy is difficult to distinguish’!" Insiders said.


　　Since yesterday was a rest day, the relevant departments have not yet gone to work, and the reporter cannot conduct further investigation. Is it legal to produce and sell this suspicious "sesame oil essence"? How to tell the true and false "sesame oil"? This newspaper will continue to pay attention.

The consumer market has achieved a ＂good start＂

　　On January 31st, General Secretary of the Supreme Leader stressed in the second collective study in the Political Bureau of the Communist Party of China (CPC) Central Committee that a long-term mechanism for expanding residents’ consumption should be established and improved, so that residents can spend with stable income, dare to spend without worries, and have a good consumption environment and a strong sense of willingness to spend.

　　The consumer market has achieved a "good start". According to the monitoring of the Ministry of Commerce, the sales of key retail and catering enterprises in China increased by 6.8% compared with last year’s Spring Festival holiday, and the consumption promotion activities were rich and colorful. The sales of new year’s goods and other commodities were strong, the leisure consumption was splendid, and the daily necessities were abundant and stable.

　　At present, all localities and departments take strong measures to enhance consumption capacity, improve consumption conditions, innovate consumption scenarios, and fully stimulate the potential of the consumer market. With multiple benefits, the consumer market is expected to accelerate its recovery and become the main driving force of the economy.

　　Policy strength, enhance consumer willingness

　　To restore and expand consumption, incentive policies play a role. During the Spring Festival holiday, more coupons are issued, which has an obvious pulling effect on catering consumption. According to the data of Meituan, after many cities in Zhejiang, Guangdong and other provinces issued coupons through Meituan, the year-on-year growth rate of food consumption in restaurants during the Spring Festival holiday reached double digits. Taking Hangzhou as an example, during the issuance of coupons for the Spring Festival, the order volume of the city’s dining room increased by 71% year-on-year, and the transaction volume increased by 80% year-on-year.

　　Recently, many provinces have deployed their work in the form of holding meetings or releasing action plans, giving priority to restoring and expanding consumption: on January 29th, Shanghai held a press conference, proposing to restore and boost consumption as one of the key tasks, and launched a number of measures from the aspects of promoting consumption expansion and upgrading, promoting mass consumption such as automobiles and household appliances, fully activating the cultural tourism market, and supporting the recovery and revitalization of the exhibition industry. On January 28th, Guangdong held a high-quality development conference, which revealed that the growth target of total retail sales of social consumer goods in the province this year was set at 6%; On January 27th, Liaoning issued a notice, explicitly promoting the recovery and recovery of consumption, and put forward such measures as diversified provision of consumption subsidies, efforts to create new consumption scenarios, increased support for county-level businesses and key commercial circulation market entities, and encouragement of reasonable housing consumption … …

　　"The focus of policy efforts is to solve some constraints faced by expanding consumption in a targeted manner." Jing Linbo, dean of the China Academy of Social Sciences Evaluation, said: looking at the demand side, in recent years, due to the epidemic, the income growth of ordinary people has slowed down and is expected to decline, and they dare not consume and are inconvenient to consume, and the tendency to save money and avoid risks has increased; Looking at the supply side, the innovation ability of market players can not fully meet the requirements of high-quality development, and there is still a certain gap between effective supply and people’s personalized and diversified consumer demand.

　　"When the pockets are bulging, consumption will be motivated." Chen Lifen, a researcher at the Institute of Market Economy of the State Council Development Research Center, suggested that the income of urban and rural residents should be increased through multiple channels, especially the consumption power of low-and middle-income residents with high propensity to consume but greatly affected by the epidemic. Increase consumer credit appropriately. We will implement the policy of giving priority to employment, support the development of industries and enterprises with strong ability to absorb employment, and timely and effectively alleviate the impact of structural price increases on people in need.

　　Improve facilities and improve consumption conditions

　　"Intelligent services are more popular. Compared with finding a route with a map before, go on road trip is much more convenient." During the Spring Festival holiday, Liu Xin, a resident of Chaoyang District, Beijing, chose to travel by car for the New Year and drove all the way from Beijing to Xi ‘an, Shaanxi. Looking for travel strategies, choosing route navigation, booking tickets for hotels and scenic spots can all be easily done through the mobile APP.

　　As an important part of consumption, the tourism market has obviously warmed up during the Spring Festival holiday, and the consumer demand for mass cultural tourism has been accelerated. According to the data center of the Ministry of Culture and Tourism, there were 308 million domestic tourist trips during the Spring Festival holiday this year, a year-on-year increase of 23.1%, returning to 88.6% in the same period of 2019; The domestic tourism revenue was 375.843 billion yuan, a year-on-year increase of 30%, and it recovered to 73.1% in the same period of 2019.

　　The improvement of consumption conditions further promoted consumption upgrading. The Spring Festival tourism market shows that with the upgrading of tourism consumption, people are more inclined to increase their stay time at their destinations and carry out in-depth tourism. According to the data of where to travel, the number of hotel rooms booked on the platform reached a record high, and the number of rooms booked for more than three days reached a record high. The average length of stay increased by 3.6 hours year-on-year, which was equivalent to one third of tourists choosing to stay one night more than last year, which drove the consumption of catering, transportation and entertainment in the destination city. "The booking situation of this year’s Spring Festival holiday is much better than last year, and the check-in period of guests is 3-mdash; 5 days. " Mr. Cheng, the landlord of Tujia B&B Shanghai Pusu Garden, said.

　　Thanks to the favorable policies to improve the consumption conditions of cultural tourism, long-distance tourism is also recovering obviously. According to data released by a travel platform, the number of domestic long-distance travel orders during the Spring Festival holiday increased by over 500% year-on-year. According to the map data of Gaode, the per capita navigation distance of users’ inter-provincial long-distance go on road trip increased by 17% compared with the same period of last year. Where to travel data shows that the average travel radius of passengers during the Spring Festival holiday has increased by over 50% year-on-year, and the average travel distance of each passenger has increased by 400 kilometers compared with last year.

　　Experts suggest that by increasing the supply of high-quality products and services, the quality level of domestic supply should be continuously improved, and the virtuous circle of supply and demand should be promoted at a higher level, so that the consumption potential can be fully released.

　　Innovate supply and increase consumption scenarios.

　　"For camping enthusiasts, prefabricated dishes are quite convenient." During the Spring Festival holiday, Li Xiao, a college teacher in Shenzhen, Guangdong Province, went camping and bought a lot of prepared dishes in advance. Li Xiao said that as a new product in the catering market, it is more convenient to cook and carry prefabricated dishes, which meets the needs of family dinners and camping picnics. The data shows that during the Spring Festival holiday, prefabricated dishes have become a popular category of food and beverage consumption, and the sales volume has increased significantly year-on-year.

　　At present, China’s residents’ consumption is diversified, multi-level and multi-faceted.

　　The deep integration of cultural tourism and tourism has accelerated the recovery of the market. During this year’s Spring Festival holiday, all localities and departments closely followed the new trend of cultural tourism consumption upgrading, provided new supply of cultural tourism products, and launched more high-quality products and services that meet the tastes of tourists.

Many places intensively promote housing consumption, and ＂Xiaoyangchun＂ is coming？

Recently, two local conferences have been held one after another. The government work reports of several cities have deployed the housing or real estate market, and most of them mentioned supporting housing to improve consumption. The fundamentals of the property market are changing.

At the same time, the transaction volume of the property market rose sharply in February. This has also changed people’s expectations of the real estate market situation — — Will the property market heat up rapidly, and the volume and price will rise together?

Intensive promotion of housing consumption in various places

On February 28th, the report on the work of Chengdu Municipal Government was released, proposing to adhere to the principle of "housing without speculation", support the rigid and improved housing needs of new citizens, young people and families with many children, further optimize the financial service policy, support the reasonable financing needs of the industry, and promote the smooth transition of the real estate industry to a new development model.

On February 27th, at the Chengdu Economic Operation Dispatching Meeting in January-February, 2023, Wang Fengchao, Mayor of Chengdu, stressed the need to comprehensively grasp the steady growth of key areas, and the second aspect was to do a good job in boosting consumption, including "better releasing the rigid and improved housing demand".

Not only in Chengdu, but also in local government work reports, the expressions about housing or real estate market can be roughly divided into two categories: one is to support the rigid and improved housing needs of new citizens and young people, and the other is to support or expand housing consumption.

Among them, some cities put forward more detailed policies and measures for the real estate market in government work reports, and clearly put forward the optimization and adjustment of existing policies.

The work report of Zhengzhou Municipal Government clearly puts forward that 12 policies and measures to support the stable and healthy development of the real estate market in Zhengzhou City should be implemented, the restricted areas should be appropriately adjusted, commercial housing for sale should be supported by group purchase, the residents of new citizens’ metropolitan area should be treated equally in purchasing houses, rent and purchase should be promoted simultaneously, the credit burden of purchasing houses should be reduced, and measures such as recognizing houses and refusing loans should be implemented, and activities such as 20% discount for talents and new citizens should be carried out to solve the housing problems of young talents, new citizens and other groups, and promote housing consumption steadily.

The work report of Xi ‘an Municipal Government devoted a section to "promoting the stable and healthy development of the real estate market". It is required to adhere to the orientation of "housing without speculation", further optimize the housing policy, support rigid and improved housing demand, standardize the development of long-term rental market, and promote the smooth transition of the real estate industry to a new development model. Continue to solve the problem of "difficulty in obtaining a permit" for housing. Resolutely fight the tough battle of "guaranteeing the delivery of the building" and ensure that more than 80% of the postponed projects will be delivered during the year. We will carry out a three-year campaign to solve the problem of "relocation difficulties" and vigorously promote the construction of resettlement buildings and resettlement work. Newly build 20,000 sets (rooms) of affordable rental housing to solve the housing problems of new citizens and young people.

Changchun has deployed the real estate market from two directions: promoting the healthy development of pillar industries and focusing on stimulating consumer demand, some of which are more powerful than other cities.

The work report of Changchun Municipal Government proposes to promote the healthy development of key pillar industries. Among them, vigorously develop the real estate industry, relieve the difficulties of high-quality housing enterprises, and meet reasonable financing needs. Strive for national special loans to speed up the pilot project of commercial housing destocking, and buy commercial housing by the government for shantytown renovation and relocation, affordable housing and rental housing.

In addition, Changchun will focus on stimulating consumer demand. We introduced new policies to promote real estate, continued to implement policies such as farmers entering cities, subsidies for talents to buy houses, and "transferring business to public", built real estate trading centers, and continued to hold housing fairs. The sales area of commercial housing exceeded 5.5 million square meters.

Yan Yuejin, research director of Yiju Research Institute, told CBN that the references to housing consumption are frequent in various places, which also reflects the government’s emphasis on housing demand and housing consumption. The housing purchase policy may be further relaxed, but this looseness cannot be understood as intensive introduction of policies. There are already many existing policies, and we should focus on digesting existing policies.

Liu Lu, a professor at Southwestern University of Finance and Economics, told CBN that the "first suite" home purchase has always been the key object of policy support. For the purchase of more than three houses, previous property market regulation policies are basically more restrictive. The second suite between the two clearly shows the attitude of "reasonable support", which is actually the embodiment of the people’s consumption upgrade in the housing field and the objective demand for improving the quality of living.

In fact, since last year, the property market regulation policies in various cities have been continuously loosened.

According to the statistics of the Central Finger Research Institute, since 2023, nearly 90 provinces and cities (counties) have optimized and adjusted their real estate policies, and introduced control measures over 100 times. According to preliminary statistics, 49 policies have been issued in 46 provinces, cities and counties in February, and the market in many places has warmed up, and the wait-and-see mood of hot cities has improved. Many places have implemented the dynamic regulation mechanism of the first home loan interest rate policy, and more than 30 cities have reduced the lower limit of the first home loan interest rate to below 4%.

Will the property market heat up rapidly?

Under the influence of a series of policies, the real estate market situation is changing, and "Xiaoyangchun" seems to be coming.

According to the data of the Central Finger Research Institute, the transaction volume of the property market in February increased by 31.9% month-on-month, and the year-on-year decline narrowed. First-tier cities increased by 5.0% month-on-month, Guangzhou and Shenzhen increased significantly month-on-month, and Shanghai both decreased month-on-month. Second-and third-tier cities as a whole rose by more than 40% month-on-month, while only Wenzhou and Fuzhou declined month-on-month, among which Jinan increased significantly, up 108.16% month-on-month. The total inventory decreased slightly, with a larger decline in Shenzhen, with a decrease of 4.89% from the previous month.

However, Liu Lu said that after the Spring Festival this year, the property market in many places across the country showed obvious signs of recovery, but the division was still large.

Liu Lu said that in first-tier cities and second-tier cities represented by Chengdu, there was little or no downward adjustment in the local property market in the early stage. At present, it is mainly reflected in the rapid expansion of the transaction volume of new and second-hand houses in the property market. In terms of price, the new house is reflected in the reduction of concessions; Second-hand housing is reflected in the owner’s reluctance to sell from wait and see, and the price has risen to a certain extent. This kind of city has a good economic fundamentals and a large net inflow of population, so the upward development trend of the property market can last for a long time.

However, Liu Lu said that in many other third-and fourth-tier cities and some second-tier cities, the downward adjustment of the property market in the early stage was more obvious. This year’s Spring Festival was superimposed by factors such as returning home and favorable policies, and the local property market showed a certain recovery, but its sustainability was worse than that of the previous cities.

Yan Yuejin also said that the income situation of ordinary people is still under pressure. The data changes in January and February are relatively large. Even if the transaction volume rises sharply, it is not easy to judge that it will heat up rapidly, and the possibility of slow heating is still relatively large. The overall trend of follow-up is optimistic, but it is necessary to guard against speculation in the middle.

Just as the market situation changed slightly, news of some policy changes began to spread. For example, in January this year, the first home loan interest rate of many local banks in Zhengzhou was lowered from 4.1% to 3.8%, but recently it was reported that the first home loan interest rate in Zhengzhou will be raised to 4.3%. Although this news has not been confirmed, it has attracted the attention of the market.

On February 28th, the Office of the Leading Group for the Steady and Healthy Development of the Real Estate Market in Yiwu issued a notice to implement eight "new policies" for real estate from now on. From April 1st, 2023, Yiwu will cancel the policy of encouraging "group buying" to buy a house, that is, cancel last year’s "on the basis of the floating record price, ‘ Group purchase ’ 10 or more sets of commercial housing can fall below 2%; Right ‘ Group purchase ’ 20 sets or more can fall below 3%; Right ‘ Group purchase ’ With the preferential policy of 50 sets and above, the market preference will gradually return to a stable state.

Yan Yuejin believes that this statement shows that Yiwu has fine-tuned some preferential housing purchase policies. The policy of Yiwu this time fully shows that some subdivided purchase policies have changed, which is also the first policy statement in China that explicitly cancels preferential treatment this year, which is of signal significance.

Yan Yuejin believes that the withdrawal of some preferential policies should be viewed objectively. To some extent, the general direction and framework of local policies are still relaxed, but there may be fine-tuning in some areas. All localities should do a good job from the perspective of market conditions and the rights and interests of buyers, and prevent the troubles caused by loose and tight policies to buyers. At the same time, all localities are also required to publicize the existing easing policies and actively encourage the release of reasonable housing consumption demand.
