复杂网络视角下的中欧海铁运输网络重要节点识别研究
Research on Identification of Important Nodes in China-Europe Sea-Rail Transport Network from Perspective of Complex Network
摘要
Abstract
The China-Europe sea-rail transport network is an important foundation for the construction of the Belt and Road.Studying the structural characteristics of the China-Europe sea-rail transport network and determining the important nodes of the transport network are of great significance for ensuring the safety of the international industrial chain and supply chain.The topology model of China-Europe sea-rail transport network is established to analyze its topological characteris-tics,and the node importance evaluation system is constructed.The node importance is calculated and sorted by combining entropy method and principal component analysis method.The nodes are deleted according to the ranking results of impor-tance,and the change trend of network parameters is analyzed.The research shows that the China-Europe sea-rail trans-port network has scale-free characteristics and small-world characteristics.After deleting the top 40 nodes according to the order of node importance,the parameters of the network change greatly,and the calculation method of node impor-tance is verified.The conclusion shows that the China-Europe sea-rail transport network has the characteristics of close connection between nodes and dense lines.The calculation of node importance can not only be based on a single index such as degree value.The nodes with the top 40 node importance are defined as the important nodes of the transport network.关键词
