Core-edge Structure Of County Economy In Jilin Province And Its Characteristics Of Space Deprivation

The regional economy is a productive complex formed by the interaction of internality and externality based on a certain geographical space.Areas can be divided according to different space sizes.A city with one or more resources that are too concentrated in its spatial scope is called a core city.According to the city classification of different scales in China,cities can be divided into regional core cities and national central cities and other cities.China has always attached great importance to the economic development of the Northeast region.The government has successively proposed a series of regional development policies such as the revitalization of the Northeast and the construction of the Ha Chang City Group.Therefore,this paper takes Jilin Province as the research area,and takes the county-level administrative region(county and county-level city)as the basic analysis unit,based on the measurement of comprehensive development level.By adding the spatial distance variable to the core city,the core-edge structure is depicted,and then the research on the core-edge structure and the overall trend of future development and evolution are explained from the perspective of spatial deprivation.This thesis is divided into six parts.The first part is the introduction part,expounds the background of the topic and the significance of the research,and briefly analyzes the research summary,research methods and purposes.The second part is the definition of relevant concepts and the analysis of the basic theoretical basis.Firstly,it expounds the related concepts and connotations of regional economy and regional economic development,county economy,deprivation and deprivation in sociology,and spatial deprivation.In this paper,the regional economic development theory,regional externality theory,growth pole theory,and core-edge theory are systematically analyzed,and the core of this paper is further clarified.The third part analyzes the spatial heterogeneity of county economic development,and starts from three aspects: evaluation method,evaluation result and basic conclusion.The fourth part discusses and analyzes the spatial heterogeneity of regional development from the perspective of “core-edge”.Firstly,the distance is measured and collected,and then the comprehensive development level of the region is measured from four aspects: economic development,social development,public service water and ecological environment.Therefore,the spatial heterogeneity of regional development under the perspective of “core-edge” is analyzed in depth.The fifth part is to explain the core-edge structure of county economic development through the perspective of spatial deprivation,and analyze its development and evolution trend.The sixth part is the conclusion part of this paper: it summarizes the main research conclusions of the paper,and puts forward further research ideas and future thinking for the research of the thesis.Through empirical analysis,it is found that in the four areas of economic development,social,public service and ecological environment,and the comprehensive development level of comprehensive integration,there is a strong or weak positive correlation with the core city.This means that in all areas of regional development,there are more regular characteristics that are farther away from the core cities.In the context of the similarity of resources and environment and external conditions of regional development,this paper attributes the spatial heterogeneity of development to the spatial interaction with core cities.The fact that the development level of the surrounding areas of the core cities is relatively low and the development level of the remote areas is relatively high confirms the existence of the spatial deprivation effect in the core areas.
