Research On The Pattern And Formation Mechanism Of The Distribution Of City Size In China

Since the reform and opening up,while China's economy has achieved remarkable results,its urbanization rate has also been developing by leaps and bounds.Specifically,the urbanization rate has increased from 17.90% in 1978 to 58.52% in 2017.In this process of rapid urbanization,large-scale and high-intensity population flows have emerged in China.The process of spatial crowding of the population has been very active and has had a profound impact on the scale structure of the urban system.So,what kind of distribution does China's city size conform to? What causes the distribution of the population among cities of different sizes? And how does this distributed economic welfare effect? As far as we know,the existing literature does not provide more understanding.However,understanding these issues is very urgent and necessary.Because of the understanding of the above issues,it not only can help us to understand the determinants of the distribution of China's urban scale,but also can point the way for the future selection of China's urbanization path.Urbanization has always been the focus of party and government policies.The spatial orientation of a large number of policies is also the city.As a test field for the implementation of policies by the party and the government,the city is the center of gravity for the country to further promote urbanization.However,there is still a great deal of controversy over whether the development of a megalopolis or a small and medium-sized city should be pursued.The reason why there is controversy is that there is no quantification of the rationalization of the distribution of the current size of Chinese cities,and there is no scientific evaluation of the corresponding policies.For example,is the scale of China's big cities really not big enough? Should the government's policy be more efficient in supporting a declining city more efficiently or supporting a small city? Will the elimination of regional disparities bring about the rationalization of the size of the city that the government wants and whether it will allow the welfare of consumers to be greatly improved? There is no consensus on these issues,either at the theoretical or practical level.Based on this,this paper first uses the calibrated DSMP/OLS global nighttime lighting data to measure the distribution and changes of China's city size;then,from the macro and micro perspectives,examine the factors affecting the size of the city,specifically In the fourth chapter,we focused on the relationship between industrial structure and the distribution of Chinese cities.In chapter 5,we examined the effects of efficiency,comfort,migration friction,and housing prices on the distribution of urban size.In Chapter 6,we will examine Recently,the more popular high-speed railways have taken into consideration the impact of the opening of the high-speed rail on the distribution of cities in the city.Finally,Chapters 6 and 7 of this paper focus on examining the performance of the economic benefits of city-scale distribution,that is,examining the scale distribution of cities.Economic performance and the impact of income gaps between regions.Through the above research,the main conclusions obtained in this paper include:(1)The size of China's cities is continuously flattened.This paper points out that using statistical data to measure the size distribution of Chinese cities,we must at least overcome the following three difficulties: First,there is no permanent population data in the statistical data;Second,in the process of rapid urbanization,due to the continuous adjustment of urban administrative divisions The inconsistent statistical data brought before and after;the third is the emergence of new cities in the process of rapid urbanization.Using the calibrated DSMP/OLS global nighttime lighting data,this paper finds two important facts: First,the distribution of China's urban scale disobeys Zipf's law;Second,since 1992,the scale distribution of Chinese cities has been flattened.Characteristics.(2)Migration friction,efficiency,comfort,industrial structure,and high-speed rail are important factors affecting the size distribution of cities,while house prices have less impact.This paper points out that 1 efficiency,migration friction and comfort are all factors that affect the size distribution of floating population and urban population in cities.Among them,the impact of migration friction on the distribution of city size is the most obvious.The concrete manifestation is that when the elimination of migration friction is When there is a difference between cities,the population will have a greater redistribution.However,unlike the migration friction,housing prices,which also represent urban crowding effects,have little effect on the size distribution of China's urban population.In addition to eliminating migration frictions,the population of medium-sized cities has rapidly increased,while Shanghai and Beijing have become extremely large.The population of the city has increased less;2 The industrial structure is an important factor affecting the distribution of the city scale.Among them,the second industry is still an important factor affecting the distribution of employment and population among different cities;3 The opening of high-speed railways has promoted the western region more.The further agglomeration of the population,and for the eastern region of economic development,the opening of the high-speed railway has exacerbated the decentralized distribution of its internal population.(3)The distribution of city size has an impact on economic performance and income disparity between regions.The paper points out that 1 the size of urban distribution has regional differences in the impact of regional income disparities.In smaller geographic scales such as cities and municipalities,the spatial structure of a single center can improve the economic efficiency of the city.On a large geographical scale,the multi-centered spatial structure can promote local economic efficiency.2 The multi-central form of the city scale distribution can effectively alleviate the income gap between regions.This multi-center distribution model is mainly achieved by optimizing the industrial structure of small and medium-sized cities within the region and accelerating the circulation of goods within the region,and in areas where the level of economic development is high,the infrastructure conditions are good,and the distance between cities is moderate,the cities The polycentric form of scale distribution has a more pronounced effect on the reduction of regional disparities.Finally,this paper combines the basic conclusions drawn with the choice of China's urbanization path,and believes that China should adopt a model of urban agglomeration that is dominated by a networked,multi-centered urban system,instead of a monopoly dominated by a megacity.Central city system development model.At the same time,the paper further aims at the future urbanization of our country from the perspectives of accelerating the reform of the household registration system,promoting the equalization of public services,consolidating the dominant position of the core cities,exerting the main functions of backward areas,and strengthening the construction of regional connectivity infrastructure.The choice of the path proposes specific policy recommendations.
