摘要/Abstract

摘要： 吉林中部城市群发展对推进吉林省新型城镇化和促进东北振兴具有战略意义。从各市县相互作用角度，基于吉林中部城市群26个市县的多指标、时间距离和列车班次数据，运用熵权Topsis、引力模型和社会网络分析方法分析各市县空间经济联系与网络结构。研究发现：1）吉林中部城市群单极化发展突出，经济综合发展水平在空间上反映由长春市区向四周衰减的态势。2）吉林中部城市群各市县关联强度前2、5、10名的经济联系在全局上呈“高联系邻近集中、低联系松散分布”，市县联系“十”字形发展主轴突出。局部上反映地级市区的连接作用突出，其他市县的弱联系制约一体化及同城化进程。3）整个城市群的FPI指数为0.101，呈现绝对主导的特征，长春市区辐射影响有限，区域节点城市发育不足。4）吉林中部城市群可分为4个城市组团。中西部区域向心集中特征显著，西北部区域对外协作效应突出，东部区域以吉林市区内外联系为主，南部区域发展潜力大。研究结果可为城市群建设和区域经济布局优化提供科学参考。

Abstract: The development of Central Jilin Urban System is of strategic significance for advancing new urbanization in Jilin Province and promoting northeast revitalization. From the perspective of the interaction between cities and counties, based on the multi-index data, time distance data, and train frequency data of 26 cities and counties in Central Jilin Urban System, the entropy TOPSIS method, the gravity model, and the social network analysis method are used to analyze the spatial economic connections and network structure of cities and counties. The study shows that:1) Single-polarization of Central Jilin Urban System is prominent. The level of economic comprehensive development reflects the characteristic of the attenuation from the urban area of Changchun to the surrounding area. 2) The economic connection intensity of the top 2, 5, and 10 cities and counties in Central Jilin Urban System is characterized by "high contact proximity and low linkage, loose distribution" and a cross-shaped development axis is prominent globally. The urban connections are more prominent and low connections in other cities and counties restrict the process of integration and urbanization locally. 3) The FPI index of the entire urban system is 0.101, which presents the characteristic of absolute dominance. The radiation influence of Changchun City is insufficient. The regional node cities are underdeveloped. 4) The Central Jilin Urban System can be divided into 4 city groups. The midwestern region has an obvious characteristic of centripetal concentration. Cities and counties in the northwestern region have outstanding collaboration effect. The internal and external connections of Jilin City are obvious in eastern region. The southern region has great development potential. The research results provide scientific reference for urban agglomeration construction and regional economic layout optimization.

Key words: Central Jilin Urban System, economic connection, regional economic integration, pole-axis, network structure
