Abstract: Based on social network analysis and clustering analysis, an empirical study of the main urban districts of Chongqing is presented. The urban centrality index model, economic connection intensity model and economic membership degree model are employed to study the spatial structure and characteristics of the urban economic networks in Chongqing. The conclusions can be drawn as follows. 1) The main districts of Chongqing are developing with the “1+2” threecore urban model; 2) The “3+6” urban system structure of Chongqing has been formed; 3) The “8-7-4” threelevel axis network has been basically formed, which leads to three major economic networks, i.e., downtown network, industrial development center network and regional future development network.

Key words: urban centrality index, economic networks, economic membership degree

摘要: 基于社会网络分析和聚类分析方法,以重庆市主城九区为实证研究单元,通过构建城市中心性指标,利用熵值法获得城市中心性指数,利用经济联系强度模型和经济隶属度模型,研究各区县的经济网络结构和作用机制。研究发现,重庆市主城区的发展正呈现“1+2”三核心城市发展驱动模式;主城区已形成“3+6”城市体系结构;主城各区已基本形成“8-7-4”三层等级强度轴线网络,并以此为基点将互通通道构建成三大经济网络,即中心城区网络、产业发展中心网络和区域未来发展网络。
