Spatial Network Structure of Logistics Development and Its Operating Effect in China’s Five Urban Clusters
Abstract：Rational and effective regional spatial network structure is beneficial to the organizational，scale，and network operation of regional logistic activities. On the basis of the comprehensive evaluation of logistics development in five urban clusters through principal components analysis method from 2005 to 2016，the author constructs gravity model to confirm the spatial correlation of logistics development between cities within each urban cluster，and then uses social network analysis method to reveal the characteristics of logistics spatial network structure，and also investigates its operating effect. First，the results show that logistics development in each urban cluster shows a continuous upward trend，and the urban clusters in eastern seaboard have better performance than that in central and west regions；the logistics development difference within urban cluster shows a gradually upward trend，accompanied by distinct gradient with bipolar or multipolar differentiation phenomenon. Second，the results show that the tightness of spatial correlation network in five urban clusters exhibits a gradually upward trend，the network grade changes smoothly，and the network efficiency exhibits a gradually downward trend，which indicates that the logistics network is becoming more and more stable. Third，the results also show that the promotion of network density and the decline of network efficiency are beneficial to improving logistics development of urban clusters and narrowing intraregional difference；breaking the strict network hierarchy is beneficial to improving logistics development of Beijing- Tianjin- Hebei，however its effects are not significant for other urban clusters；the promotion of degree centrality and closeness centrality are beneficial to improving logistics development， but the effects of betweenness centrality are regionally different. So to better promote the coordinated development of urban cluster’s logistics industry，we should，first，fully consider the regional advantages and resource endowment of each city，clarify the functional position of each city in urban cluster’s logistic development，and promote the industrial interaction and spatial coordination；second，we should enhance spatial productivity of hub cities and strengthen its emissive power on lagged behind cities to realize the overall prosperous and regional coordinated development；and third，we should improve transportation infrastructure among cities，eliminate the institutional barriers hindering element flow，realize the spatial spillover effects，optimize logistic spatial distribution，and strengthen spatial network structure to improve the capability for value creative of logistics industry.
