吉林省城市空间结构及地方中心城市腹地范围界定

将经济流与交通流相结合，运用社会网络分析法，分析了吉林省城市空间联系网络特征，选出吉林省地方中心城市，根据各市（县）间的综合联系程度界定地方中心城市的腹地。结果显示：① 吉林省的经济、公路和铁路3个网络联系密度均偏低，长春市处于各网络中的核心地位，全省范围内各网络联系程度差异较大；② 从综合联系网络来看，中部与其他地区的联系较为密切，东部和西部地区联系较弱；中部地区内的2个凝聚子群间联系有待加强，吉林省中部地区一体化发展任重道远，产业协调发展是未来的发展方向；南部地区内部的联系应进一步提升，促进南部轴线的发展；③ 结合吉林省47个市（县）的点度中心度、点入度和点出度值及实际发展需要，将长春市、吉林市、四平市、辽源市、通化市、延吉市和白城市作为吉林省的地方中心城市，其中，长春市的辐射带动能力最大，白城市最低；延吉市与敦化市应组团发展，成为东部地区的发展核心，共同带动东部地区发展；白城市应增强自身的中心性和辐射带动能力，充分发挥西部门户城市作用。

Urban Spatial Structure of Jilin Province and Scope of Local Central City Hinterland

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.
