| Regional spatial structure is one of the main research fields of regional development and hotspot issues,regional economic spatial structure evolution is not only the important content and spatial embodiment of regional economic development,but also one of the driving forces of regional economic evolution system.The regional spatial structure is the reflection of regional economic activities in the geographical space,regional spatial structure is evolving continuously,with the development of the regional economy.At the same time,the regional spatial structure is the "function" of regional development,regulating the spatial structure can also adjust and optimize the regional economic development status.The city group has become the main city space form of China's regional economic development and urbanization,with the development and integration of urbanization and regional economy,the evolution of economic spatial structure of city group is an important part of the development process and the development level of the city group.Since the reform and opening up of China,the Northeast China regional economic development has appeared weak growth and transition difficulty,presents "northeast phenomenon" and the "new northeast phenomenon",especially in recent years,the economic growth of northeast region shows new round decline trend,compared to the national average growth rate,the central government began to implement the strategy of revitalizing the Northeast china since 2003,but it does not solve the deep-seated contradictions existing in the development process of the northeast economy fundamentally,Northeast China is still one of the major problem areas of regional economic development at present in our country.City group economic growth and development is the main content of the northeast China's economic growth and development,the dissertation studies on central Jilin city group,one of the three largest city groups in Northeast China,from the spatial difference and the pattern of evolution from the perspective of economic growth pattern and process of city group,constructing a coupling coordination model of economic growth rate,efficiency and quality of the city group,analyses the structure and function evolution law of central city group since the implementation of the development strategy of northeast China,and puts forward the regulation path and countermeasures of regional spatial structure optimization and coordinated regional development,in order to enrich the theory and practice of regional economic spatial structure evolution and regional coordinated development research,provide a reference for the coordinated development of the regional economy of the northeast old industrial area.The full text is divided into eight chapters,the main research contents are as follows:The first chapter is the introduction.This chapter describes the research background,the basis and significance of the research,and then summarizes the main research contents,research methods and technical route.The second chapter is the theoretical analysis and literature review.Firstly,it expounds the concept and connotation of urban agglomeration,regional spatial pattern evolution and regional coordinated development.Then it analyses the economic growth theory,regional development stage theory,spatial polarization theory and regional spatial relevance theory,and the regional economic growth and regional development stage,regional spatial correlation and the pattern of evolution and regional economic growth efficiency and quality of existing research are reviewed,further defined the research focus and the idea of this study.The third chapter defines the city agglomeration space,analyzes the temporal characteristics and background of the regional economy evolution of the city group,and then analyzes the economic development stage of the central urban agglomeration in Jilin province using fuzzy comprehensive evaluation method.The fourth chapter calculates and comprehensive analyses the spatial structure and the evolution of the central Jilin city group,based on the theory of city economics and city geography,including the first distribution and evolution of city group,city agglomeration urban system scale structure and its evolution,spatial organization structure and spatial-temporal function structure evolution of the city group.The fifth chapter analyses evolution pattern of regional economic differences and spatial polarization of the central city group,using the range,standard deviation,Gene coefficient,Cui Wang index and Theil index statistical analysis method,based on GIS technology at three different spatial scales,including the province,the city and county scale.Then,county economic spatial pattern evolution characteristics and spatial correlation of the evolution characteristics were analyzed to explore the process and regularity of the regional integration since 1993,especially in the northeast revitalization policy implementation in the past 10 years,using the IDW spatial interpolation,the economic center,standard deviation ellipse,Moran 's I and Getis-Ord G*i methods.The sixth chapter analyzes the theoretical connection of regional economic growth speed,growth efficiency and growth quality,economic growth evolution of city groups in central Jilin province,the spatial differentiation and spatial correlation characteristics were calculated,then using the DEA model and the entropy method to calculate the economic growth quality of city group efficiency and economic growth.Then it analysis the quality of economic growth efficiency and economic growth evolution characteristics and spatial evolution characteristics,finally constructs the coupled coordination model of the rate and efficiency and quality of regional economic growth,and comprehensively analyzes the evolution characteristics and spatial and temporal variation characteristics.Spatial classification of the coupling coordination types of each county unit is carried out.The seventh chapter is the analysis of regional economy evolution mechanism and spatial development of the city group,first elaborates regional economy evolution mechanism of the city group,and then puts forward the adjusting direction and path of the coordinated development of city agglomeration,based on the conclusion of the previous chapters.Then it analyzes the dominant factors of the reorganization of regional spatial economic structure.And it puts forward the countermeasures to optimize the economic spatial structure of the city group,based on the agglomeration`s spatial structure and its evolution.The eighth chapter is the conclusion part of this paper,which summarizes the main conclusions and characteristics of the study,and puts forward the further research problems and research directions according to the shortcomings of the paper. |
