After reform and opening up，China relies on demographic dividend，Rapid economic development，Become one of the largest markets in the world。However, Chinese people have always suffered from "phobia" about population data。2016 Starting from year，Cities such as Beijing and Guangzhou have successively formulated population plans，Control population growth rate，Easing the challenges faced by big cities。To this，Ctrip Executive Chairman Liang Jianzhang thinks，Large population、Scale effect of large market，Especially in the context of globalization，Has outstanding advantages，Population control cannot drive away smog，What drives away is the vitality of the city。

January 6, 2017，The China and Globalization Think Tank (CCG) held a series of roundtable seminars in Beijing, "Liang Jianzhang: Population，Innovation and Urban Planning”，Liang Jianzhang, who has just become the vice chairman of CCG, starts from the population、Age、Agglomeration and other aspects discussed the 188bet online sports betting relationship between innovation and population，and indicate the population、Innovation determines the vitality of China’s economy in the future，Determines whether China’s economy can transform from a middle-income country to a developed country。

Over the years，Liang Jianzhang has been thinking about letting the public、Decision makers get rid of the thinking rut of "there are too many Chinese people"。In his opinion，Large population、Scale effect of large market，Especially in the context of globalization，Has outstanding advantages。Young people are suitable for innovation and entrepreneurship，The current aging population is the main factor that hinders innovation and entrepreneurship and even reduces the vitality of enterprises。From a macro perspective，Economic policies will also become more conservative as the population ages。
Brexit is such an example，Japan is also very obvious，Japan’s aging population has caused nearly、The vitality of Japan’s innovation and entrepreneurship in the past thirty years has been greatly affected，Its macro policy implements a very low interest rate or even deflationary policy，Enable less efficient companies to continue。And examples prove，The younger the country, the stronger the vitality of innovation。

Liang Jianzhang’s judgment，China will age rapidly in the future，By 2020, China’s aging population will be similar to that of Japan around 1990。If there are no major changes in China’s population policy，China’s population structure will be very severe in the future，Even if the two-child policy is relaxed now, it is still not enough，Because newborns account for less than 10% of the world’188bet app s newborns。The effect of financial subsidies is not obvious，Insufficient investment in human resources，Nine-year compulsory education、College entrance examination and kindergarten、There is still a big gap in nurseries, etc.。

For the so-called "big city disease" exaggerated by public opinion，Liang Jianzhang also has a different view，He believes that big cities are gathering industries、Talent gathering、Has advantages in cross-border industries and world exchanges。China’s urban population is relatively small，The largest country should have the largest city，China obviously does not。And population control，Will affect innovation，Exacerbating the gap between rich and poor，It is also not conducive to industrial upgrading and environmental improvement。

Liang Jianzhang’s view is，The current gap between rich and poor is mainly the income gap between urban and rural areas，China’s urban and rural incomes have not shrunk with urbanization and industrialization，It is mainly the household registration system that limits population mobility。As for transportation and cities、Relationship between population size，No positive correlation。The most congested places are middle-income cities in developing countries，Instead of megacities in developed countries。For example，The roads in New York are denser than those in Beijing，The land utilization rate in Tokyo is significantly higher than that in Shanghai。This explains the problem。

Some people believe that population control will help alleviate smog，Liang Jianzhang said，There is no necessary connection 188bet sports betting app download between smog and city size，Urbanization rate is inversely proportional to pollution。Urbanization, especially large cities, can help alleviate the current serious environmental pollution problems。On the one hand, urbanization, especially urbanization, will improve the level of economic development，And it is easier for big cities to implement various environmental protection measures。On the other hand，Most of the industries in big cities are service industries or high-end manufacturing，Less pollution than heavy industry。Also，The more urban population there is，The higher the efficiency of infrastructure utilization。

Based on the analysis of China’s current population problems and understanding of the crisis，Liang Jianzhang thinks，Relax household registration restrictions，Let more outsiders in Beijing、Living and working in big cities such as Shanghai，Not only can it promote China’s innovation and economic development，Narrowing the gap between rich and poor，It also helps to alleviate the current serious environmental pollution problem，And "Population control cannot drive away smog，What drives away is the vitality of the city。”

To this，The participating scholars expressed their agreement，Professor Yuan Gang, School of Government, Peking University emphasized，The country now needs to attach great importance to population issues，Freeing up the second child is a concrete measure，But the current effect is not obvious，There is no so-called baby boom。Because the proportion of people willing to have a second child is less than half，Letting go of having a second child will not fundamentally solve the problem。He suggested not 188bet Online Sports Betting and Casino to restrict fertility，Don’t subsidize those who don’t have children，Let the population take its course。At the same time, family planning personnel should be appropriately abolished，Personnel transferred to health or other departments。

Huang Wenzheng, population columnist of Caixin.com, also further emphasized the seriousness of the current population problem，Not just about aging，What’s more, the trend of population decline is not optimistic。China’s population has dropped from 35% of the world’s population 200 years ago to 22% in 1949.1%，18 so far.5%，And low fertility rate will reduce the population by 55% every 50 years in the future，In addition, the number of women of childbearing age will decrease by 45% in the next 10 years，Making China’s population decline irreversible，Judging from the current trend development，It will take at least two or three generations to increase China’s population growth rate to the world average。
