重庆区域经济联系结构研究——基于社会网络分析

Research on the Structure of Economic Ties in Chongqing:Based on the Social Network Analysis

基于修正后的引力模型计算重庆市各区县2000—2016年的经济联系强度,利用社会网络分析方法分析不同时点的经济联系强度,从而分析重庆市空间经济联系结构特征变化情况。结果显示:重庆各区县间的经济联系水平呈逐年提高趋势,全市一体化进程逐步加快,但部分偏远区县与其他区县的经济联系水平还有较大提升空间;各区县之间经济联系区域性特征明显,经济联系主要集中在主城、渝西的区县之间,渝东北、渝东南的区县之间经济联系不对称和不均衡现象还比较突出;主城凝聚子群内部联系紧密,影响范围仅限于渝西地区,影响力度并不高;渝东北、渝东南地区尚未形成联系密切的区县群。

Based on the revised Gravity model, economic relation intensity of different regions in Chongqing from 2000 to 2016 was calculated. Social network analysis method was used to analyze economic relation intensity of different time points, which can analyze the change of spatial economic relation structure in Chongqing. Results show that the level of economic ties between districts and counties of Chongqing shows a trend of increase year by year, the integration process of the whole city is speeding up gradually, but there is great space to improve for economic ties level of some remote counties with other districts and counties. Economic ties between districts and counties have obvious regional characteristics, economic ties mainly concentrate on the central city and the west of Chongqing. Economic ties between northeast and southeast of Chongqing are asymmetric and imbalanced. The cohesive subgroup of the main city is closely related, and the influence is limited to the western of Chongqing, The areas of northeast and southeast of Chongqing have not formed a close association.
