On November 18, 2019, Professor Zhou Guanghong from the National Meat Center of Nanjing Agricultural University led a team to use the sixth generation of pig muscle stem cells to obtain artificial pork weighing 5 grams after 20 days of culture. This is the first artificial meat made from animal stem cells in China.

A week later, a vegetable protein artificial meat of OmniPork’s new pork was officially launched on Tmall platform, with a price of 230g per serving in 28 yuan. As a result, artificial meat is stepping on the table of Chinese people step by step. While feeling novel, many people are also worried about this kind of unnatural "fake meat".

What exactly is artificial meat? According to Wikipedia, artificial meat is usually divided into two categories: plant meat and cultivated meat. Plant meat refers to food products made from plant raw materials, which imitate the taste, taste or appearance of animal meat. The OmniPork new pork mentioned above is such artificial meat.

Cultured meat refers to the meat made by cultivating animal muscle cells through bioengineering, and what Professor Zhou Guanghong’s team cultivated is cell cultured meat.

Qianjiang evening news published the report "Artificial Meat, Is It Really Unacceptable?" on November 26th, 2019, saying that artificial meat was produced to fill the gap between supply and demand of natural meat, and at the same time it may be healthier and more environmentally friendly.

(Original qianjiang evening news)

Is the supply and demand of natural meat unable to meet people’s needs? Does natural meat cause environmental pollution and resource consumption? Is artificial meat more nutritious than natural meat? Artificial meat does not contain antibiotics and can artificially control nutrients? After checking the above questions, the reporter of the nuclear record came to the conclusion:

1. China’s domestic natural pork market is in short supply and demand;

2. The production and consumption of natural meat pollutes the environment and consumes a lot of resources;

3. At present, the calories, fat and cholesterol of artificial meat on the market are lower than those of real pork, but the content of protein is not as good as that of real pork;

4. Vegetable protein artificial meat does not contain traditional animal antibiotics, but only the cell-cultured meat in the laboratory can artificially control the nutritional components.

Checkpoint 1: Is China’s natural pork unable to meet the market demand?

A: At this stage, the domestic pork market is tight in supply and demand, and the import volume has increased significantly.

Bill Gates is a supporter of artificial meat. He has invested in many artificial meat producers such as Impossible Foods, Beyond Meat. Qianjiang evening news quoted a quote from Bill Gates’ blog: "It’s good news that economic growth has made meat affordable for more people, but the bad news is that by 2050, the demand for meat we need will double that of 2005. However, we don’t have that much land for grazing. "

Is the emergence of artificial meat because the market supply of natural meat can’t match the market demand? In view of the demand of natural meat in China market, the reporter took pork as an example and made a verification.

The reporter found the Statistical Yearbook of China from 1999 to 2019 on the website of the National Bureau of Statistics, which counted the pork production in China in the past 20 years. According to the data of the National Bureau of Statistics, the pork production in China increased from 31.58 million tons in 1996 to 54.03 million tons in 2018, which nearly tripled in 22 years. According to the data of the OECD database (https://stats.oecd.org/), the pork consumption in China increased from 31,365,200 tons in 1996 to 55,218,900 tons in 2018.

(OECD network: pork consumption in China)

As for the import and export volume, according to the data of China Agricultural Industry Development Report 2019, the pork import volume in China has started to increase significantly since 2010.

(Source: China Agricultural Industry Development Report 2019)

We calculated by the formulas of [pork production-pork consumption] and [(pork production+pork import)-(pork consumption+pork export)], and got the following results respectively:

(The author calculated according to the data of China Agricultural Industry Development Report 2019, OECD Network and National Bureau of Statistics)

It can be seen that although China’s pork market maintains a balance between supply and demand under the compensation of imports, the annual production has been less than the annual consumption since 2010, and the gap has been expanding. Correspondingly, the import volume of pork increased by 17.77% from 2000 to 2018, and the supply and demand of domestic pork market tended to be tight.

In 2019, due to African swine fever, a series of prevention and control policies and changes in slaughter, the domestic slaughter of pigs decreased significantly, and the production capacity of pigs and fertile sows continued to decline. The effect of tight supply in the pork market was concentrated during this period, leading to a sharp rise in domestic pork prices.

Based on the above materials, the demand for pork products in China is increasing, and the shortage of supply and demand in the domestic natural pork market will become increasingly prominent.

Checkpoint 2: Does the production and consumption of natural meat cause environmental pollution and massive consumption of resources?

A: The production and consumption of natural meat will pollute the atmosphere and require a lot of land and water resources.

"qianjiang evening news" reported that "livestock manure will pollute land and water sources, and their farts contain a lot of methane, and the greenhouse effect of methane is 25 times higher than that of carbon dioxide. Animal husbandry has caused considerable pressure on the environment. There is no excreta in artificial meat, and three-dimensional production takes up very little land. "

According to the greenhouse gas emissions of pig breeding, the reporter consulted the article "Development of China’s Pork Industry and Estimation of Greenhouse Gas Emissions" published in China Pig Industry in October 2015. By calculating the emissions of methane in pig intestines, methane in feces and nitrous oxide in feces (methane and nitrous oxide are listed as greenhouse gases by intergovernmental climate change organizations), it is concluded that in 2012, only 112 million tons of greenhouse gases were emitted during pig breeding (excluding other processes).

Not only that, Xu Wenchuan, School of Environment, Nanjing University, published his master’s degree thesis "Analysis of Greenhouse Gas Emissions from China Residents’ Dietary Consumption" in May 2018, pointing out that the greenhouse gas emissions from pork in China’s dietary consumption (including the whole process of breeding) have been increasing from 252 million tons in 2002 to 325 million tons in 2012 (Figure 1), and the proportion has also been rising, from 27% to 28% (Figure 2 Compared with the 7.954 billion tons of national greenhouse gas emissions in 2012 pointed out by China Carbon Emissions Trading Network, this number accounts for about 4.1% of China’s total greenhouse gas emissions.

(Figure 1 Source: "Analysis on the Changes of Greenhouse Gas Emissions of China Residents’ Dietary Consumption")

(Figure 2 Source: "Analysis on the Changes of Greenhouse Gas Emissions of China Residents’ Dietary Consumption")

Regarding the consumption of land and water resources in pork production, the reporter looked through the data of the 8th LCA International Conference on Agricultural Food held in Rennes, France in October 2012. According to the statistics of the organization in charge of the conference, the output of each ton of edible pork needs 4.9m3 of water resources (see the figure below), and beef, mutton and other meats consume more.

(Source: Report of the 8 th LCA International Conference on Agricultural Food)

According to the data of the first verification point, the domestic consumption of pork in China in 2018 is about 55.22 million tons, which requires about 270.5 billion cubic meters of water resources according to the above-mentioned meeting data. According to the "China Water Resources Bulletin 2018" published by the Ministry of Water Resources of People’s Republic of China (PRC), the total domestic water consumption in 2018 is only 85.99 billion cubic meters, so the water consumption used only for pork production in that year can supply the daily life of the people of the whole country for at least three years, and if other meats are added, it will be more.

At the same time, meat production based on animal husbandry consumes a lot of land resources. According to the comparative analysis of environmental impacts of agricultural production systems published by Clark & Tilman in the journal Environmental Research Letters, According to the data in the article "Agricultural input efficiency, and food choice", the production of pork in protein requires 0.13 square meters of land, while that of beef and mutton in protein requires 1.02 square meters.

(source: comparative analysis of environmental impacts of agricultural production systems, agricultural input efficiency, and food choice)

However, the data of the National Bureau of Statistics show that the available grassland area in China is decreasing year by year. From 2003 to 2018, the available grassland in China decreased from 3.31 million square kilometers to 2.194 million square kilometers. The reduction of grassland area limits the development space of animal husbandry, and also confirms the worry that "there is no more land for grazing" in Bill Gates’ blog.

(Data source of grassland area change in China: Statistical Yearbook of National Bureau of Statistics)

Based on the above information, the production and consumption of natural meat have indeed caused the problems of environmental pollution and massive consumption of resources.

Checkpoint 3: Artificial meat is low in calories, fat and cholesterol, and has higher nutritional value?

A: Compared with real pork, OminPork artificial meat currently on the market in China has lower calorie and fat content and zero cholesterol, but its protein content is also slightly lower.

Qianjiang evening news reported that "artificial meat may be healthier than natural meat. Artificial meat production process does not need to use antibiotics, but also can artificially control the nutrients in the meat. According to the data, this artificial meat (which was reported to be listed on the e-commerce platform on November 25th, 2019) has just been marketed and retailed with plant-derived protein as raw material. Compared with real pork, the fat is 70% lower, the calorie is 65% lower, and the cholesterol is 0. Moreover, in the case of the same protein content as pork, the iron and calcium contents are 2-3 times higher than pork. "

The reporter inquired that the artificial pork currently listed in China is only OminPork new pork, which is taken as a representative for verification. This artificial meat is a future meat product developed by Right Treat, a food research company of Hong Kong Green Monday Company, and sold through the Green Common Tmall international platform. This is a kind of vegetable protein meat, the main ingredients are water and plant protein concentrate such as soybean, mushroom and rice.

(Chinese version of ingredient list provided by Tmall International)

The ingredient list displayed in the official flagship store of Green Common shows that the artificial meat has an energy of 74 kilocalories per 100g, a fat content of 1.5g and a cholesterol content of 0. If we compare the composition of this artificial meat with that of real pork with 84% lean meat and 16% fat meat, then this artificial meat is 66% lower in calories and 68% lower in saturated fat than real pork.

(ingredient list in the official flagship store of Green Common)

There are differences between the above product data and the data mentioned in the report of qianjiang evening news: the data expression of fat, energy and cholesterol are basically the same; However, it is worth noting that the protein content of this artificial meat is 12.5g, which is slightly lower than that of real pork (17.9g), which contradicts the reported "protein content is the same". At the same time, this artificial meat has 2.6 times the calcium and 1.27 times the iron content of ordinary pork, rather than the vague "2-3 times" in the report.

In addition, the report doesn’t mention the fat-lean ratio of real pork (lean meat: fat meat ≈ 84: 16), and different fat-lean ratios will lead to different nutritional components of pork, which may further affect readers’ understanding of the nutritional value of artificial meat.

Checkpoint 4: Artificial meat does not need antibiotics, and can the nutrients in the meat be artificially controlled?

A: Vegetable protein meat does not need antibiotics, but only cell-cultured meat can artificially control nutrients.

The article "Characteristics of Plant Extracts and Their Application in Sow Production" published in Journal of Animal Nutrition in 2017 indicates that the abuse of antibiotics in large-scale pig farms is very serious, which will not only lead to antibiotic residues in meat products, but also lead to the emergence of drug-resistant bacteria, which seriously threatens human health. It can be seen that farmers add antibiotics to feed, and antibiotics remain in pigs, so there is a saying that "natural meat contains antibiotics".

In contrast, the ingredient list of OminPork mentioned above shows "no added antibiotics".

(ingredient list in the official flagship store of Green Common)

As for the idea that "nutrients can be artificially controlled" in qianjiang evening news, the reporter of the Nuclear Record found through investigation that this is mainly aimed at cultivating meat.

According to Wikipedia’s definition, the principle of cultivating meat is to extract stem cells from animals, then put them in test tubes or Petri dishes to divide and grow, and finally produce muscle tissue, in which the nutrients can be controlled.

As early as 2005, the team of Jason Masini, Ph.D., who studied agricultural economy and public health at the University of Maryland, put forward two technologies with large-scale meat production potential in the scientific journal Tissue Engineering. In response to these two methods, Masini said: "You can even control nutrition. For example, most meat has high omega-6 fatty acids, and artificial meat can be replaced by omega-3, which is a healthy fat."

(Artificial meat cultivated by Professor Zhou Guanghong led the team. Source: "National Meat Center" WeChat official account)

However, as mentioned above, the argument that artificial meat can artificially control nutrients is limited to cell culture of meat in vitro, and it is unlikely that this technology will be popularized to the market on a large scale. According to the report of "Global Network" on November 25th, 2019, "When did China artificial meat come to the people’s table? Expert: Lobster with Super Price, experts from College of Animal Science and Technology of China Agricultural University and Beijing Agricultural College think: "(China) is still in the research and development stage. With the current technology, a large amount of animal serum needs to be added to the system of cultivating cell meat, and the serum comes from blood, so animals must be slaughtered in order to obtain serum. In addition, it is still in the early stage of research and development, and it needs to invest a lot of manpower and material resources. The cost of artificial meat far exceeds that of ordinary meat."

(The World Wide Web reported, "When did China artificial meat come to the people’s table? Expert: Super-priced Lobster)

To sum up, this report is suspected of confusing two types of artificial meat with each other. For vegetable protein artificial meat, because vegetable protein is used, animal antibiotics are not used. However, the so-called "artificial control of nutrients" is only used for cultivating meat in the laboratory, and it is unlikely that this technology will be popularized to the market at this stage.

summary

At present, the supply and demand of China’s meat market is relatively tight, and traditional animal husbandry has caused a lot of air pollution and occupied land and water resources. It is under such circumstances that artificial meat gradually enters people’s field of vision. As far as the ingredients of artificial meat are concerned, the only vegetable protein meat OmniPork sold in the domestic market at present is composed of pure plants, which is lower in calories, lower in fat and cholesterol, and does not contain animal antibiotics. However, the so-called "artificial control of nutrients" is only aimed at another kind of artificial meat-cell-cultured meat, and this technology is not suitable for market promotion in the short term.

With the constant turmoil of meat, can artificial meat, with its more environmentally-friendly concept and more artificial and safe raw materials, get out of the way of thinking of vegetarian consumers, occupy a place at the table of Chinese people, and successfully challenge the cognition of traditional pork and even meat? Let’s wait and see.

Read the original text

Although there are rumors circulating on the Internet that BYD X-dream has a 1000-kilometer battery life and 800V ultra-high voltage flash charging, at present, BYD officials have not launched a production model with such endurance.

As a concept car, X-dream’s actual cruising range after mass production is still difficult to determine. Therefore, the current purchase of BYD cars has not yet been able to enjoy the driving experience of more than 1000 kilometers of pure battery life.

BYD Tang Family:

As a modified model, BYD Tang EV has demonstrated its strength in the market with a pure battery life of 730 kilometers. Although it has not reached the milestone of 1000 kilometers, it still has obvious advantages compared with similar competing products. Although the plug-in hybrid version of "BYD Tang DM-i" has a pure battery life of only 252 kilometers, its comprehensive battery life can reach 1200 kilometers when it is fully charged with oil, meeting the needs of long-distance travel.

Byd Han family:

Han EV’s 715km pure battery life makes it competitive in BYD pure electric vehicles. Han family’s plug-in hybrid models are equally excellent, with a maximum pure battery life of 242 kilometers and a comprehensive battery life of 1300 kilometers when full of oil and electricity, with excellent performance.

BYD Song Family:

Song PLUSDM-i provides 51/110 kilometers of pure battery life, and the comprehensive battery life of long-life models can reach 1200 kilometers. Song ProDM-i and Song MAXDM-i also performed well, taking into account endurance and fuel economy.

BYD Qin Family:

Qin PLUSDM-i and Qin PLUSEV have endurance of 55/120 km and 420/510/610 km respectively. Qin PLUSEV shows reliable endurance performance with its lightweight design and low wind resistance.

Summary:

Although BYD has not officially launched a model with a pure battery life of more than 1,000 kilometers, its existing product lineup has been considerable in terms of cruising range, and the comprehensive endurance of plug-in hybrid models is also worth looking forward to. When choosing BYD cars, users should consider the endurance performance according to their own needs and driving habits, as well as the actual working condition endurance data of the vehicles.

Cctv news: On July 14th, Beijing Municipal Bureau of Human Resources and Social Security released the adjustment plan of relevant social security treatment standards in 2022. According to the national requirements, since January 1, 2022, Beijing has continued to adjust the basic pension for retirees of enterprises, institutions and institutions (including retired and retired personnel).

This year’s adjustment will continue to be carried out in accordance with the combination of quota adjustment, linked adjustment and appropriate inclination, and continue to maintain the adjustment method of increasing inclination to retirees with early retirement time, continuous service and long payment period, so that they can enjoy the fruits of social development more.

This adjustment is aimed at retirees who have gone through retirement formalities before December 31, 2021 (inclusive). It is estimated that more than 3.18 million retirees from enterprises, institutions and institutions will be benefited, and pensions will be reissued from January this year, of which enterprise retirees and reissued pensions will be paid in place on July 15. The specific adjustment measures are as follows:

(A) the quota adjustment of basic pension

For each retiree, 36 yuan will be increased each month.

(B) linked to adjust the basic pension

1. Linked to the payment period

This year, we will continue to implement the method of generally increasing the basic pension linked to the payment period. Among them, for retirees who have paid for 10 years or more, the 3 yuan will be increased every month for every 1 year; For the remaining months less than the whole year, the monthly increase is 0.25 yuan. If the payment period is less than 10 years (excluding retirees who transfer from land acquisition to work), the 30 yuan will be increased per person per month; Retirees whose payment period is less than 15 years will receive an increase of 45 yuan per person per month.

2. Linked to the pension level

According to the monthly basic pension level of retirees before the end of 2021, the per capita disposable income level of residents in this city in 2021 (6250 yuan) is used as the baseline to divide into two grades, and each person with more than 6250 yuan will increase 20 yuan per month, and each person with less than 6250 yuan will increase 50 yuan per month.

At the same time, in order to give consideration to fairness, for retirees whose monthly pension level was above 6,250 yuan before adjustment, if it is still below 6,300 yuan after adjustment linked to the pension level, it will be replenished to 6,300 yuan. [See Chart 1]

Chart 1

For example: Uncle Wang, 64 years old, with a payment period of 37 years and a basic pension of 6,255 yuan/month. According to the corresponding standards, 20 yuan should be raised to 6275 yuan when added to the original pension. However, in December 2021, when people with pensions below 6,250 yuan rose to 50 yuan, some people would reach 6,300 yuan (6,250+50), which was higher than Uncle Wang’s 6,275 yuan. Therefore, Uncle Wang was given a higher 25 yuan to make him reach 6,300 yuan. In the adjustment linked to the pension level, Uncle Wang actually increased 45 yuan every month.

This year’s adjustment, Uncle Wang increased by 192 yuan per month, and the basic pension after adjustment was 6447 yuan/month.

(3) Appropriate tilt to senior retirees

For retirees who retire early and are older, in order to further improve their basic living standards, we will continue to give preferential treatment to senior retirees this year. For senior retirees who have reached the age of 65 or above before December 31, 2021, after adjustment according to the above measures, they will once again enjoy the preferential policy of four grades from 40 yuan to 70 yuan. That is, retirees aged 65 to 69 will increase their 40 yuan every month; 70 to 74 years old, each person will increase 50 yuan every month; Each person aged 75 to 79 will add 60 yuan every month; 70 yuan will be increased every month for each person over 80 years old.

On this basis, for retirees over 65 who have paid for 30 years, the 5 yuan will be increased every month, so as to reflect the further preference for retirees with early retirement time, continuous service and long payment period. [See Chart 2]

Chart 2

For example: Aunt Zhao, 68 years old, with a payment period of 33 years, has a basic pension of 4,500 yuan/month.

This year’s adjustment, Aunt Zhao added a total of 230 yuan every month, and the basic pension after adjustment was 4,730 yuan/month.

For example: Uncle Liu, 80 years old, with a payment period of 40 years and a basic pension of 5,700 yuan/month.

This year’s adjustment, Uncle Liu increased by 281 yuan per month, and the basic pension after adjustment was 5981 yuan/month.

(D) Two special adjustment methods

First, continue to adjust the retirement benefits of old workers who participated in revolutionary work before the founding of the people’s Republic of China. This adjustment will still be made according to the previous year’s method, that is, those who participated in the revolutionary work from July 7, 1937 to September 2, 1945 will receive an increase of 335 yuan per person per month; Those who took part in revolutionary work from September 3, 1945 to September 30, 1949 received an increase of 305 yuan per person per month. On the basis of the adjustment of the above two standards, they also enjoy the preferential policy for senior retirees. This adjustment will generally increase by 375 yuan/month to 405 yuan/month.

The second is to ensure that the retired military cadres of enterprises and the former industrial and commercial personnel are not lower than the average pension level of enterprise retirees in the city after adjustment. After increasing the basic pension according to the quota and payment period and increasing the basic pension according to the absolute amount, if the basic pension of enterprise retired military cadres and former industrial and commercial workers is lower than the adjusted average pension level of enterprise retirees in the city, it will be replenished to the average level. At the same time, senior retirees who have reached the age of 65 or above before December 31, 2021 (inclusive) also enjoy the preferential policy for senior retirees.

The pensions adjusted by the retirees before December 31, 2021 (inclusive) of the municipal institutions and institutions will also be paid in place before the end of July.

　　As of January 25th, except Jiangsu, Zhejiang, Hebei, Yunnan, and Xinjiang, 26 provinces in China have handed in the 2020 economic answer sheet.

　　Judging from the total economic output in 2020, among the 26 provinces, the total economic output of 21 provinces exceeds 1 trillion yuan. Guangdong has been ranked first in the country for 32 consecutive years. Last year, the total economic output exceeded the 11 trillion yuan mark for the first time. According to the data of the World Bank, this data also surpassed the total economic output of Russia and South Korea in 2019, followed by Canada.

　　Judging from the economic growth rate in 2020, among the 26 provinces, the economic growth rate of 16 provinces exceeds or is equal to the national performance. The central and western regions remain in the lead. In 2020, Tibet’s GDP growth rate will lead the whole country, with an annual economic growth of 7.8%.

　　In 2020, the regional GDP of Hubei Province was 4.34 trillion yuan, down 5.0% from the previous year, and the decline was 34.2 percentage points narrower than that in the first quarter. From "pressing the pause" in the first quarter to "restarting the recovery" in the second quarter, and then "accelerating the overall recovery" in the second half of the year, Hubei withstood the huge impact of the "pause" for 76 days, and the economy recovered and developed well in the face of enormous difficulties and challenges throughout the year.

　　Guangdong’s total output exceeds 11 trillion yuan, ranking first in the country for 32 consecutive years.

　　From the perspective of the economic aggregate in 2020, Guangdong has no suspense to reach the top of the list again. The annual economic aggregate exceeded 11 trillion yuan, ranking first in the country for 32 consecutive years. The total amount even exceeds the GDP of Russia and South Korea in 2019. Considering the impact of the epidemic, China is the only major economy that has achieved positive economic growth, which means that Guangdong’s GDP will definitely exceed that of Russia and South Korea in 2020.

　　In 2020, the regional GDP of Guangdong Province was 11.076 trillion yuan, a year-on-year increase of 2.3%. This economic volume can be described as "extremely rich". At present, Guangdong’s GDP in 2020 is equivalent to 1.7101 trillion US dollars.

　　According to the World Bank’s data on the economic aggregate of Russia and South Korea in 2019, Russia’s GDP in 2019 was 1.6999 trillion US dollars, ranking 11 th in the world; South Korea’s GDP in 2019 was 1. 6467 trillion US dollars, ranking 12th in the world. In 2020, Guangdong’s total economic output will steadily surpass that of Canada. Jiangsu, whose economic aggregate has followed Guangdong all the year round, has not yet announced its GDP in 2020. However, in 2019, the total economic output of Jiangsu approached 10 trillion yuan, and the regional GDP reached 9.96 trillion yuan, an increase of 6.1% over the previous year.

　　Jiangsu will undoubtedly become the second province in China with GDP exceeding 10 trillion yuan. Judging from the performance in 2020, Jiangsu’s GDP in the first quarter of last year fell by 5% year-on-year; The first half of the year increased by 0.9% year-on-year; The first three quarters increased by 2.5% year-on-year, and many indicators reached or exceeded the same period last year.

　　The ancients often used metaphors to illustrate the pursuit of ideals, involving foundations, methods, paths, goals and their relationships.

　　China Economic Net, Beijing, July 22 (Reporter Yang Miao) With the release of the national GDP data for the first half of 2016, as of July 21st, 21 provinces and cities have released their own GDP data for the first half of 2016.

　　According to the statistics of China Economic Net reporter, among the 21 provinces and cities that have published data, the GDP growth rate of Beijing and Shanghai is the same as that of the whole country, while that of Yunnan and Hebei is slightly lower than that of the whole country, and the GDP growth rate of the remaining 17 provinces is higher than that of the whole country. At present, Chongqing has the best performance, with a growth rate of 10.6% in the first half of the year, which is 3.9 percentage points higher than the national level.

　　China’s GDP increased by 6.7% in the first half of the year.

　　The national economy is generally stable.

　　The National Bureau of Statistics recently released the national economic data for the first half of the year. It is understood that the GDP in the first half of the year was 34,063.7 billion yuan, with a year-on-year increase of 6.7%, and the growth in the second quarter was 6.7%, which was the same as that in the first quarter. On the whole, the national economy has maintained a generally stable, steady and progressive development trend.

　　Among them, the added value of the primary industry was 2,209.7 billion yuan, a year-on-year increase of 3.1%; The added value of the secondary industry was 13,425 billion yuan, up by 6.1%; The added value of the tertiary industry was 18,429 billion yuan, up by 7.5%.

　　Experts said that in the context of the continued slowdown in world economic growth, it is really hard-won for China’s economy to achieve 6.7% growth.

　　The GDP growth rate of 17 provinces in the first half of the year was higher than that of the whole country.

　　Chongqing’s growth rate for 10 consecutive quarters is "among the best"

　　According to the statistics of China Economic Net, judging from the ranking of GDP growth rate of 21 provinces and cities at present, the growth rates of 17 provinces and cities such as Chongqing, Guizhou, Tianjin, Jiangxi, Anhui, Fujian, Qinghai, Hubei, Hainan, Henan, Zhejiang, Hunan, Sichuan, Guangdong, Shaanxi, Guangxi and Inner Mongolia all exceeded the national level, and the year-on-year growth rates all exceeded 7%.

　　The transcripts of Chongqing and Guizhou in the first half of the year are still bright. At present, the GDP growth rate in the announced provinces ranks in the top two, with an increase of more than 10%.

　　According to China Economic Net, Chongqing has maintained its economic growth rate in the forefront of the country for ten quarters under the great downward pressure. Zhang Fumin, deputy director and spokesman of Chongqing Municipal Bureau of Statistics, said that it is not easy for Chongqing to maintain such a high growth trend. He believed that the rapid development of five functional regions, industrial transformation and upgrading, structural adjustment, accelerated formation of new impetus and new economy worked together to support the beautiful economic landscape of Chongqing in the first half of the year.

　　In addition, Guizhou’s performance has been excellent in recent years. Luo Guanghua, a professor at the Party School of Guizhou Provincial Party Committee, pointed out that Guizhou’s rapid economic development is mainly due to the small total GDP, which is relatively fast.

　　The GDP growth rate of the six provinces in the first half of the year declined compared with the first quarter.

　　Hainan has the largest decline.

　　According to the statistics of China Economic Net, as can be seen from the table, compared with the GDP growth rate in the first quarter, the GDP growth rate of Chongqing, Hainan, Henan, Shaanxi, Inner Mongolia and Beijing declined in the first half of the year. The GDP growth rate of Jiangxi, Anhui, Fujian, Qinghai, Shanghai and Yunnan was the same as that of the first quarter. The GDP growth rate of the other nine provinces has increased compared with the first quarter.

　　Among them, the GDP of Zhejiang Province increased by 7.7% in the first half of the year, 0.5 percentage points faster than the 7.2% in the first quarter.

　　According to China Economic Net, the business income of information transmission, software and information technology services in Zhejiang increased by 37.9% in the first half of this year, higher than the growth rate of 29.1% in the first quarter. It can be seen that the tertiary industry in Zhejiang has played a key role in economic growth. In addition, the reporter also noticed that the new economy in Zhejiang, especially in Hangzhou, has nurtured many influential enterprises, such as Alibaba, and encouraged the development of the Internet industry in many ways. These factors have directly affected the performance of Zhejiang’s economic data in the first half of the year.

　　Compared with the first quarter, Hainan’s GDP growth rate in the first half of the year dropped by 1.6 percentage points, but Hainan’s overall economy is still improving, with a growth rate of 8.1%, exceeding the national growth rate by 1.4 percentage points.

The Evening News, an urban evening newspaper under Jiefang Daily Newspaper Group, will be officially closed on January 1 next year, becoming the first newspaper to be closed after the establishment of Shanghai Newspaper Group.

On the afternoon of 23rd, Dongfang.com officially announced that the Evening News will be officially closed on New Year’s Day next year. This indicates that after the establishment of Shanghai Newspaper Group, the Shanghai newspaper industry shut down and turned to activities to start. According to the report of China News Network, the employees of Evening News will participate in the internal two-way selection of Shanghai Newspaper Group one after another, and the personnel placement will start tomorrow.

The staff of the Evening News revealed that Qiu Xin, Party Secretary and President of Shanghai Newspaper Group, announced the news at the staff meeting held that afternoon. According to insiders, at 10: 00 am on the 23rd, the operating company has announced its dissolution. At half past three in the afternoon, the Evening News held a closing meeting. According to the report of China News Network, the employees of Evening News will participate in the internal two-way selection of Shanghai Newspaper Group one after another, and the personnel placement will start tomorrow.

The front page of the Evening News published on December 23rd, 2013 will be closed on New Year’s Day next year.

Founded in Shanghai in 1999, Evening News is an urban evening newspaper under the newspaper group of Jiefang Daily. On October 28th, 2013, with the approval of the Shanghai Municipal Committee of the Communist Party of China, Jiefang Daily Newspaper Group and Wenhui Xinmin United Newspaper Group were integrated and reorganized to form Shanghai Newspaper Group. Evening News became the first newspaper to close after the establishment of the new group.

As soon as the news that the Morning News is about to close, the fate of other newspapers under the Shanghai Newspaper Group has attracted many speculations. According to the data, the Shanghai Newspaper Group consists of Wen Wei Po, Xinmin Evening News, Oriental Morning Post, Bund Pictorial, Jiefang Daily, Morning News, Evening News and Jiang Shen Service Herald. Among them, except Bund Pictorial and Jiang Shen Service Herald, the other six daily newspapers, morning newspapers and evening newspapers are the main distributors of distribution and advertising share in Shanghai, and they have also formed a certain competitive pattern.

On October 28th, 2013, Shanghai Newspaper Group was established and Han Zheng was unveiled.

In this regard, Wei Wuhui, a well-known media researcher at Shanghai Jiaotong University, analyzed that among the previous media in Shanghai, the Morning News of Jiefang Daily Newspaper Group and the Oriental Morning Post of Wenhui Xinmin Newspaper Group did not have the possibility of merging. "The profit of the morning paper is very high, second only to Xinmin Evening News, and Dongzao has a good reputation in Shanghai. Moreover, the positioning of Dongzao and Morning Post is also different. The Morning Post is positioned as a citizen reader and Dongzao is positioned as a senior intellectual, so there is no possibility of merger between them. " Wei Wu waved and said.

In Wei Wuhui’s view, the "cold winter" of the traditional media industry came as early as the middle of this year. According to the data of Shanghai Press and Publication Administration, the advertising revenue in Shanghai’s main media business in 2012 was 10% lower than that in 2011, and an "avalanche" occurred in 2013. "In 2008 and 2009, it can be said that the economy was depressed, and this year it can only be said that it is an inevitable trend of the decline of traditional media."

In addition, Zhang Zhian, deputy dean of the School of Communication and Design of Sun Yat-sen University, said that this is a wake-up call for practitioners of traditional media. Zhang Zhian said, "The closure of the Evening News has made some practitioners realize that they are no longer holding iron rice bowls. If you can’t adapt to the integration of reports and journalists in the new media environment, you will simply write news and comments, and you will be eliminated. "

Let’s analyze it from different angles and see the differences between the new generation car networking system and CarPlay/Carlife:

Differentiation of OEM perspectives:

First of all, from the standpoint of automobile manufacturers (OEMs), CarPlay is dominated by Apple, and the role of OEMs is relatively limited. The application of CarPlay needs to be operated through the mobile phone. Although the OEM saves the traffic fee, the data control is in the mobile phone, not the car itself. The new generation of car networking systems seek deeper integration, such as zebra system, which aims to become the center of car machines, not just the copy of mobile phone functions.

Differences in integration depth:

Mobile phone mapping technologies such as CarPlay are less integrated with vehicles and only run as on-screen applications. The new generation car networking system can be deeply integrated with vehicle hardware to realize voice control, such as BYD system of BYD, which allows multiple modules to be controlled and creates more possibilities.

Improvement of user experience:

In terms of user experience, mapping systems such as CarPlay have limitations, such as the conflict between navigation and mobile phone operation. The new generation car networking system solves these problems through deep integration, and provides a smoother interactive experience, such as controlling vehicle functions through voice commands without disturbing drivers.

Evolution of hardware configuration:

Due to the limitation of function, the hardware configuration of traditional lathe is relatively simple. With the development of intelligent network, the hardware of the new generation car has also been significantly improved, such as supporting multi-touch and higher-level user experience design.

Generally speaking, the difference between the new generation car networking system and CarPlay/Carlife lies in the improvement of integration, control ability and user experience. In the era of intelligent networking, the car is no longer a simple entertainment system, but as the core component of car intelligence, providing drivers with a more convenient and intelligent interactive experience. Therefore, it is no longer applicable to discuss the substitution relationship between traditional car and CarPlay/Carlife. The future development trend is to deepen the interaction between people and cars and promote the popularization of intelligent travel.
