The recognition of urban status and its development from the perspective of space of flows is an important cognitive basis for further promoting new urbanization. Based on the data of county road passenger coach service and supported by Ucinet and ArcGIS software, this paper analyzes the urbanization centrality and its influencing factors in Jilin province from three aspects( the whole network, the centrality of point and influencing factors). The results show that: 1) The overall network structure of the province is relatively loose, the core network strength is weak, and the spatial connection between towns needs further improvement; The spatial connection in the city area is relatively close, but the intercity connection is obviously insufficient, and the development process of the regional linkage is relatively slow. 2) Degree centrality in municipal level is generally high, and the communication ability of provincial fringe towns is generally in the subordinate location; The spatial connection effect of urban nodes has the characteristics of regional difference, and the spatial connection in the regional is mostly completed through the intermediary action of prefecture-level cities; The level of cities and towns in the view of comprehensive centrality has the characteristics of first-place distribution, and presents the center-hub pattern of one pole and three cores and the cluster phenomenon of eight sub-groups and four districts in regional towns. 3) By applying the method of geographical detector to the study of the influencing factors of urban centrality, it is concluded that the per capita disposable income of urban residents has little effect on the centrality of urban nodes in the province. Economic scale, population scale, industrial structure, traffic carrying capacity and other factors have a significant impact on the status and role of cities and towns. Road network density is still one of the factors that affect the spatial connection level of cities and towns. Therefore, it is necessary to enhance the resource agglomeration capacity of the core towns in the eastern and western regions of the province, optimize the industrial structure of cities and towns on the edge of the province, enhance the market vitality, rationally allocate of regional transportation resources and improve the traffic infrastructure in marginal cities and towns.
Key words: new urbanization; centrality; Geodetector; highway traffic flow; town node; Jilin Province
