Research on the Multi-Scale Spatial Structure of Express Logistics in the Yangtze River Economic Belt under the Background of E-Commerce:Based on the Perspective of"Flow Space"
How to analyze the network structure and interaction of regional"flow"in different spatial scales according to the same network dimension,and then explore the influencing factors of the network,is the current research direction and problem of urban logistics network.Based on the link data of Alibaba logistics service platform,this paper attempts to explore the spatial characteristics and driving factors of express logistics network of 130 cities in the Yangtze River economic belt and their inner urban clusters from the perspective of multi-scale space from part to whole through ArcGIS,social network analysis and QAP analysis.The results show that:①the density of express logistics network in the Yangtze River economic belt has reached a high level,but the spatial difference of link strength is significant.The"grade diffusion"effect is prominent under different spatial scales.It is easier for developed cities and regions to have high-intensity and dense express logistics links.The core urban agglomeration form the core express logistics corridor of the economic belt;②The logistics high-scale output cities are mainly concentrated in the downstream urban agglomeration of the economic belt,while the low-scale input cities are mainly concentrated in the upstream urban agglomeration.The urban nodes of the midstream urban agglomeration are relatively balanced in terms of logistics function classification;③QAP results show that there are differences in the causes of regional express logistics networks under different spatial scales,but the express"flow"generally tends to flow between cities with relatively developed economy and consumption,high e-commerce and Internet levels,and relatively complete express logistics infrastructure.
