Analysis of Structural Characteristics and Influencing Factors of Industrial Linkage Network of Yangtze River Delta Urban Agglomeration
Industrial linkage is of great significance for promoting the process of regional integration in the Yangtze River Delta.Based on the data of the Yangtze River Delta urban agglomeration from 2011 to 2021,the modified gravity model and social network analysis method are used to explore the structural characteristics and influencing factors of the industrial linkage network.The results show that:(1)There is a significant industrial linkage path and a spatial correlation network within the Yangtze River Delta urban agglomeration.(2)There is a higher degree of centralityin core cities and central cities,and the cities with a higher out-degree show a trend of agglomeration to Shanghai,while the cities with a higher in-degree show a trend of diffusion from Shanghai.(3)The network is characterized by"small world"structure.The composition of cities in the agglomeration subgroup is moving from being relatively concentrated to dispersed,that is,the industrial linkage gradually breaks the restrictions of prov-inces and regional boundaries.(4)The differences in industrial structure,economic development level,transpor-tation development level and innovation development level promote the formation of industrial linkage network.Therefore,it is necessary to give full play to the leading role of cities in the central area of the Yangtze River Del-ta,guide the rational layout of industries in the Yangtze River Delta,and strengthen inter-regional cooperation in technological innovation,so as to promote the integrated development of the Yangtze River Delta.
