Abstract:In order to obtain the research hotspot of port logistics field in China, the empirical analysis of the Chinese journal full text database of CNKI in 2913 samples of keywords in the literature information. This paper uses the theory of complex network to construct a contains 50 nodes, 982 edges (keyword co-occurrence) undirected weighted network. Calculation analysis tool Pajek statistical index, path, clustering coefficient using social network, the network has small world, scale-free property. The network degree are centrality and betweenness centrality based on separate, research focus, research focus are closely linked, but the attention degree of difference.
