中欧班列沿线贸易--物流网络结构优化分析

Evolution and Optimization of Logistic Network Structure Driven by China Railway Express

分析中欧班列节点城市贸易-物流网络结构,有利于推进现代化物流枢纽的建设。运用熵权法测算中欧班列国内节点城市物流绩效指数,通过修正引力模型分别测算2010年、2014年和2019年中欧班列沿线主要节点城市间贸易-物流联系强度,并采用地理可视化展现中欧班列驱动下沿线贸易-物流网络演变,结合网络结构分析得出中欧班列沿线主要节点城市的贸易-物流网络中心性和凝聚子群,为沿线集货中转枢纽的选取提供理论依据。结果显示,中欧班列有效改善了中欧城市间的经济关联格局,显著推动了沿线贸易-物流网络结构的优化。

The analysis of the logistics network structure of the China-Europe Railway Express joint cities is conducive to promoting the construction of modern logistics hub.The entropy weight method was adopted to measure the logistic performance of domestic node cities.The strength of the trade-logistics link between the major nodes along China-Europe Railway Express in 2010,2014 and 2019 was measured by the modified gravity model,and the geographic visualization indicated the evolution of trade and logistics network structure driven by the China-Europe Railway Express.Through analyzing the network structure,the trade-logistics network centrality and cohesive subgroups of the main node cities along the China-Europe Railway Express were obtained,providing a theoretical basis for the selection of cargo transfer hubs along the line.The results show that the China-Europe Express can effectively improve the economic linkages between Chinese and European cities,and significantly promote the optimization of the tradelogistics network structure along the route.
