成渝地区双城经济圈物流空间联系及其网络结构研究
Research on logistics spatial connection and network structure of Chengdu-Chongqing double city economic circle
摘要
Abstract
Regional logistics is vital to economic development.In order to reveal the current logis-tics connection strength and network structure of the double city economic circle in Chengdu-Chongqing area(hereinafter referred to as Chengdu-Chongqing area),based on the perspective of geographical space connection,this paper takes 16 cities at prefecture level and above in Chengdu-Chongqing area as research objects during the research period from 2009 to 2019,and uses the gravity model to construct logistics network in Chengdu-Chongqing area.The network density,network centrality and coacervation subgroups are measured by the social network analysis meth-od,with the linkage strength and spatial layout analyzed deeply.Results:In the time range of this study,the spatial difference of urban logistics quality level is significant,and the intensity of logistics connection is different in Chengdu-Chongqing area.The network density increased from 0.902 3 to 0.904 2,which is at a relatively high density level with a small fluctuation range,strong polymerization degree and close logistics connection.However,the internal network den-sity in Chengdu-Chongqing region is unbalanced,with the highest density in the central part,slightly lower density in the northern part and the lowest density in the western part.On the whole,the logistics network presents a radial network structure with Chengdu and Chongqing as the core and development in opposite directions.关键词
