Abstract:

Combining economic flow with traffic flow, using social network analysis method and analyzing the characteristics of urban spatial connection network in Jilin Province, selecting local central cities in Jilin Province, and defining the hinterland of local central cities according to the degree of contact between cities (counties).The result are as follows: 1) The economic, road and railway links in Jilin Province are all low in density, and Changchun is at the core of each network. Degree of network contact varies greatly across the province; 2) From the perspective of the integrated network, the central region has closer links with other regions, and the links between the eastern and western regions are weak; The links between the two cohesive subgroups in the central region need to be strengthened. The integrated development of the central region of Jilin Province has a long way to go, and coordinated industrial development is the future development direction. The links within the southern region should be further enhanced to promote the development of the southern axis; 3) Combining the degree of centrality, point-in and point-out values and actual development needs of 47 cities (counties) in Jilin Province. Changchun, Jilin, Siping, Liaoyuan, Tonghua, Yanji and Baicheng were taken as local central cities in Jilin Province. Among them, Changchun has the largest radiation driving capacity and the lowest in Baicheng; Yanji and Dunhua should form a group in development and become the core of development in the eastern region, jointly driving the development of the eastern region; The Baicheng should strengthen its centrality and radiation-driven ability and take full effort to play the role of the western gateway city.

Key words: local center city, city hinterland, economic flow, traffic flow, Jilin Province
