Formation Mechanism and Identification Method of Logistics Corridors
Logistics corridors are important functional systems of the comprehensive national transport net-work,serving as the foundation for the mutual promotion of domestic and international dual circulation.In order to identify logistics corridors more accurately,the definition of logistics corridors is further clarified through the analysis of domestic and foreign concepts.This paper proposed that the formation of logistics corridors was fundamentally based on the networked development of transportation infrastructure,and was the result of the horizontal integration of complementary network components and the vertical integration of node clustering,which was characterized by the polarization of hub points and the large-scale of traffic volume.On this basis,the identification idea of"finding points first,locating routes later"was clari-fied.With the core idea of determining"points"with location entropy and"lines"with maximum tree(edge),an identification method based on city,traffic and economic data was proposed.Through multi-source data collection,nodes identification,routes identification,corridors gathering and corridors identification,a"eight vertical and seven horizontal"logistics corridor layout was put forward finally.Compared with traditional methods,the identification method of points selection and routes determina-tion has higher accuracy,which can further show the operation characteristics such as cargo flow direc-tion,transportation structure,freight scale,etc.,and provide the possibility to carry out the correlation analysis on logistics corridors and economic development.
