Research On Financial Competitiveness And Radiant Power Of Central Cities In The Middle Reaches Of Yangtze River Agglomerations

The urban agglomeration in the middle reaches of the Yangtze River is an important part of the Yangtze River Economic Belt and an important support for the rise of the central part of China.Enhancing the radiation-driving capacity of the central city of the urban agglomeration is an important way to promote economic development.At present,the economic development of urban agglomerations in the middle reaches of the Yangtze River lags behind that of developed urban agglomerations in the Beijing-Tianjin-Hebei region and the Yangtze River Delta.Therefore,the leading role of central cities should be emphasized to accurately identify the economic development status of urban agglomerations in the middle reaches of the Yangtze River.Finance is the core driving force of regional economic development,and regional economic development is closely related to regional financial development.This paper takes the central cities of the three sub-groups of urban agglomerations in the middle reaches of the Yangtze River as the research object,and explores the spatial structure and evolution trend of the financial development of urban agglomerations by discussing their financial competitiveness and radiation force respectively.It also provides countermeasures and suggestions for the economic development of urban agglomerations in the middle reaches of the Yangtze River and the construction of regional financial centers.Based on financial development theory,industrial competition theory and location theory,this paper firstly analyzes the financial development status of the three central cities in the middle reaches of the Yangtze River--Wuhan,Changsha and Nanchang,and finds that the economic and financial development of the central cities is relatively rapid.However,there are some problems,such as large gap between cities in financial development,insufficient efficiency of urban financial services to the real economy,and thin layout of urban financial industry.After that,this paper adopted entropy weight TOPSIS comprehensive evaluation method,gravity model and fracture point model analysis method to collect relevant data of 31 cities in the middle reaches of the Yangtze River urban agglomeration,studied the financial development quality of central cities and its spatial correlation and influence intensity,and used ARCGIS software to visualize the research results.Draw the financial network and financial radiation range between cities.The empirical results show that: in recent years,the financial development difference between cities in urban agglomerations is more and more obvious,and the urban development of urban agglomerations is not coordinated.The financial competitiveness of Wuhan,Changsha,Nanchang,Xiangyang and Yichang are all at the first level,and the spatial structure begins to develop from Wuhan as the core to "multi-center".The gravitational strength between cities generally shows an upward trend,but there is no significant change in several cities which are closely connected with the central city,and the financial interaction between them and the fringe cities of the urban agglomeration is insufficient.The financial radiation effect of the central city is not obvious,and the radiation scope fails to cover all the cities in the urban agglomeration.Based on the above research results,this paper puts forward countermeasures and suggestions from three aspects: regional financial centers of urban agglomerations,urban financial networks and financial business environment: Differentiated measures should be implemented according to local conditions to promote the formation of financial centers with different gradients;Strengthen the construction of financial network between cities,the government to do a good job in the top-level design of financial development;Create a sound financial ecological environment,eliminate the flow of financial resources resistance.
