国家物流枢纽城市物流空间联系及其网络特征分析
Spatial Connection and Network Characteristics of National Logistics Hub Cities
摘要
Abstract
To further study the structural characteristics of logistics spatial connection networks in national logistics hub cities,this paper first analyzed the relevant data of 110 national logistics hub cities.Then the paper utilized the modified gravity model and social network analysis method to analyze the logistics spatial connection between hub cities and the network characteristics.The results are as follows.①The density of logistics spatial connection networks is generally low in national logistics hub cities in China and all regions,indicating that the freight connection between hub cities is not close enough.② Hub cities with a high degree of centrality are also the cities with the highest ranking of intermediary centrality.These cities become the radiation poles of freight and logistics resources in the country or region and drive the joint development of other hub cities.③The network presents a"core-semi-core-edge"structure in space,and the hub-and-spoke hierarchical structure is evident.④The cluster characteristics of hub cities are obvious,which can be divided into 8 subgroups,whereas the interaction between subgroups is not apparent.⑤ Shanghai,Beijing,Shenzhen,Guangzhou,and other logistics cities have the advantage of being located in the network structure hole,while Qinhuangdao,Baoding,Datong,and other hub cities do not have the advantage.关键词
