The Geoeconomic Relations Between The Central City And Surrounding Cities Of Chengyu City Group

Over the past 40 years of reform and opening up,Chengdu-Chongqing urban agglomeration is based on the southwest,radiating northwest,facing Europe and Asia,and plays the role of "connecting west","new growth pole","economic growth",and "H" type strategic pattern in China's land.Point ”and other important roles,and was approved by the State Council as a national city cluster in March 2018.In the development process of Chengdu-Chongqing urban agglomeration,it is the core task of the current development of Chengdu-Chongqing urban agglomeration to clarify the function of the city and optimize the regional spatial pattern,and this requires research based on the geo-economic relationship between the regional central city and surrounding cities.Based on the actual situation of Chengdu-Chongqing urban agglomeration and the theory of geo-economic relationship,this paper uses the modified gravity model,fractal model,and European distance model to analyze the four aspects of the geo-economic relationship between the seven regional central cities and the surrounding cities in the Chengdu-Chongqing urban agglomeration---Integrated four-in-one comprehensive research on the strength of economic ties,the direction of economic action,the relationship of economic competition and cooperation,and strategic matching,and at the regional level and the urban agglomeration as a whole The inner and surrounding cities put forward corresponding regional and urban development countermeasures.The study found that the geo-economic relationship between the central city of Chengdu-Chongqing urban agglomeration and the surrounding cities in the area is in the strength of economic ties.A few areas have faults and "blank areas" at the level of economic ties.The regional central cities are underdeveloped and of poor quality Most regional cities have an important relationship with the historical development process,related support policies,and geographical location.The development of regional central cities needs to be tapped;in the direction of economic function,they are mainly biased towards national central cities,and only some regions have a balanced development trend,and comprehensive infrastructure roads are interconnected.The degree needs to beimproved and optimized;in the economic competition and cooperation relationship,there is an overall situation in which competition for economic factors is greater than cooperation.It is manifested in capital conversion efficiency,labor efficiency,and product export capacity.Some regional central cities compete very closely with surrounding cities.In a fierce or uncertain state,the industrial structure between cities needs to be optimized and improved;in the strategic matching relationship,deepening cooperation is the minority,strengthening cooperation and enhancing complementarity are the majority,and some regions urgently need to adjust their strategies.Therefore,in order to optimize the geo-economic relationship between the central city of Chengdu-Chongqing urban agglomeration and the surrounding cities,it is necessary to build a hierarchy of economic links between the cities to promote the integrated development of Chengdu-Chongqing urban agglomeration,and accelerate the construction of rapid infrastructure transportation network to improve the space economy Contact efficiency,and construct a reasonable industrial structure and industrial chain to improve industrial radiation and undertaking capabilities.
