Study On The Linkage Strength And Its Influencing Factors Between Ganzhou And Cities And Urban Agglomerations In China

In the wave of economic globalization and global urbanization,the cross-regional flow of factors of production accelerates,which promotes the change and adjustment of enterprise space,organization and location,and further promotes the reconstruction of urban space.Regional,national and global urban interconnection networks are increasingly emerging.The interconnection between cities in the world is closer,and the relationship between cities tends to be flat.Cities do not exist in isolated regions.Urban development has broken through the limitations of geographical space.It is necessary to strengthen the interaction with other cities to achieve complementary advantages and coordinated development.Studying the strength of urban linkages is helpful to understand the law of urban development,improve urban economic functions,and promote the division of labor,cooperation and coordinated development among cities.Firstly,this paper reviews and summarizes the relevant literature at home and abroad critically,and puts forward that this study should adopt the research method of urban relevance from the perspective of enterprise relevance.Taking Ganzhou City as the research object,this paper constructs the connection network between Ganzhou and the whole country based on the headquarters-branches relationship in the database of China's industrial enterprises.By means of descriptive statistical analysis and headquarters-branches method,the spatial structure and evolution characteristics of Ganzhou City's urban network are studied from three perspectives of overall correlation,inward agglomeration and outward radiation,and from the dual scale of city and urban agglomeration.Empirical study was conducted.On the one hand,on the urban scale,the characteristics of Ganzhou's association with external cities are described,and the characteristics and evolution of its network are analyzed from three aspects: overall correlation,inward concentration and outward radiation.On the other hand,on the scale of urban agglomeration,the evolution of Ganzhou's association with different urban agglomerations and the differentiation of urban connection within urban agglomerations are compared and analyzed.The results show that:(1)the city-related network formed between Ganzhou and other cities is gradually developing,and the strength and breadth of the network are increasing,and the degree of the close connection with the whole country is increasing.The evolution of the geographic spatial distribution of the cities associated with Ganzhou is path-dependent,mainly distributed in the southeastern coastal areas and along the Tokyo-Kowloon Railway,which shows the external situation.Transportation is an important way for cities to establish economic ties with other cities.(2)The investment of Hong Kong businessmen promotes the economic development of Ganzhou,but most of the Hong Kong-funded enterprises only use Ganzhou's low-cost land and labor force for industrial transfer,and do not form an industrial chain with Ganzhou's local enterprises,which weakens the endogenous growth capacity of Ganzhou's economy.This development path of labor-intensive enterprises and simple processing trade locks Ganzhou at the low end of the global value chain.(3)Influenced by geographical proximity,low business cost and Hakka cultural circle,Ganzhou and the Pearl River Delta urban agglomeration have always been in a high position.(4)Ganzhou's export-oriented radiation was greatly influenced by the administrative region economy in its early stage,and is now transforming into an economic economy.(5)Accessibility and comprehensive urban strength are the main factors affecting the connection strength between Ganzhou and other cities.
