A Study On The Evaluation Of Logistics Capacity In The Guangdong-Hong Kong-Macao Greater Bay Area And Its Hub-and-Spoke Logistics Network Construction

The regional coordinated development of the Guangdong-Hong Kong-Macao Greater Bay Area is crucial,and the logistics industry plays an important role in promoting the regional coordinated development.The determination of regional logistics capacity deepens the understanding of regional logistics industry and provides reference for the spatial layout of regional logistics industry.Reasonable and efficient regional logistics network can effectively improve the circulation efficiency of regional logistics industry and optimize the rational allocation of resources.Therefore,it is of great significance to evaluate the logistics capacity of the Greater Bay Area and to build regional logistics networks based on regional logistics integration and to promote the coordinated development of the Greater Bay Area.First of all,the connotation of regional logistics capacity is analyzed,a G1-CRITIC screening model suitable for large index set and meeting the importance and information content is established,and a regional logistics capacity evaluation index system matching the characteristics of the Guangdong-Hong Kong-Macao Greater Bay Area is constructed.Secondly,the G1-CRITIC method is used to determine the weight of each index,and the regional logistics capacity of the Greater Bay Area urban agglomeration is calculated combined with the GC-TOPSIS evaluation method.Finally,the regional logistics capacity index of the Guangdong-Hong Kong-Macao Greater Bay Area is introduced into the logistics gravity model.Based on the determination of axis logistics city,logistics gravity measurement and radiation logistics city membership,the Greater Bay Area is constructed.The study concluded that:(1)logistics scale,development environment and talent support are important factors affecting the regional logistics capacity of the Greater Bay Area.(2)The Greater Bay Area has great differences in logistics capacity among cities,and Guangzhou and Hong Kong have significant advantages.Shenzhen and Macao have closely formed four major core logistics node cities in the Guangdong-Hong Kong-Macao Greater Bay Area.(3)The logistics network of the Guangdong-Hong Kong-Macao Greater Bay Area is closely connected,presenting a spatial pattern of one axis,two wings,three cores and three channels.
