Research On Spatial Agglomeration Of Industry And Population In Yunnan Urban System

China's urbanization level has made remarkable achievements since the Reform and Opening,but also accumulated and precipitated a lot of contradictions and criticisms,such as the urbanization fell behind the industrialization,the shortcomings of extensive urban development route,irrational urban industrial planning and so on.In recent years,China put forward a new urbanization construction aimed at eliminating the urban-rural dual system and a reasonable urban system construction is particularly necessary in this context.As a place in the southwest border area there are manyprominent issues which include that the regional industrial development is relatively backward,resource utilization is not high and the division of labor is not clear and how to promote industrial division of labor and optimize the use of resources to build a scientific and rational,sustainable development of urban system,Is particularly urgent and important.The establishment of scientific urban system should be begin with the rational distribution of labor force and urban functional division,linking the population pattern and industry development,accelerating the optimization and adjustment of urban system through the spatial agglomeration of population,industrial or metropolitan area.Based on the above,this article attempt to use the new economic geography theory,which has developed rapidly in recent years and cites the theory of industry and population aggregation as a conomic theory support of Urban System Planning after summarizing the domestic and abroad research findings.This paper systematically summarizes the spatial agglomeration relationship between urban industrial development and population movement and forms a mechanism to promote the development of urban system and regional urbanization level with urban agglomeration as the main body.At the same time,the reduction of transportation cost can directly stimulate the flow and agglomeration of population and industry,and the reasonable spatial layout of urban system should first improve the regional transportation network.Then,based on the above theoretical model,the paper focuses on the present situation and trend of agglomeration in Yunnan Province from the aspects of industry and population to provide concrete data support for the construction of urban system in Yunnan Province.Then,the zipf model is used to analyze the urban scale distribution in Yunnan Province and and it is concluded that the distribution of urban scale in Yunnan Province is gradually increasing,that is,the population gradually flows to the big cities.Finally,the econometric model is used to test the causes of industrial agglomeration,and the law of industrial agglomeration in Yunnan is explored from the quantitative point of view.From the perspective of "producing the city",this paper provide a certain theoretical guidance for scientifically determining Yunnan urban system population size and the layout of industrial development.Finally,according to the background conditions of Yunnan urban development and the method of dividing the fault points,Yunnan Province will be divided into urban groups in central Yunnan,urban groups in southeastern Yunnan,urban groups in northeastern Yunnan,urban groups in western Yunnan and urban groups in southwestern Yunnan And the northwest town of Yunnan town group.According to the theoretical analysis,Yunnan should try to cultivate the region with comparative advantages of the industry to promote the development of urbanization level by urban and industrial integration in order to promote the development of urban system.With the development of the six cities and towns as the carrier,the paper puts forward the construction of the traffic system and the development direction and ideas of the future development of the urban agglomeration aimed at promoting the spatial agglomeration of the industry and population and promoting the development of the surrounding towns and optimizing the urban spatial layout of Yunnan Province Urbanization development model.
