摘　　要：为获得班轮航运网络的结构特点,对现实航线数据进行计算机仿真,并利用复杂网络理论对网络的拓扑特性进行统计与分析.结果表明,班轮航运网络有一定的小世界特性,具有较短的平均路径长度和较大的聚类系数;其度分布服从幂律分布且具有典型的无标度网络特性;班轮航运网络具有富人俱乐部特性;其同配性系数为0.0574,未体现出明显的同配性.Statistical topological features of network were analyzed by combining complex networks theory with computer simulation of actual ship route data to get the structure characteristics of liner shipping network. Simulation and analysis results show that liner shipping network（LSN） is a small-world network with short average path length, high degree of clustering and its degree distribution follows a power law, the rich nodes＇ connectivity in the network is evidently higher than the others. The assortativity coefficient of LSN is 0. 0574 and not obvious assortative.
