摘　　要：从复杂网络理论角度出发,验证了集装箱航运网络具备无标度和小世界特性.由集装箱航运网络节点度分布、度相关性以及度与介数相关性分析得到了度较大的节点对集装箱航运网络影响程度较大的结论.选择度较大节点作为优先攻击目标,随机生成节点序列作为出错目标,进而比较出错和攻击对集装箱航运网络聚集系数、平均距离和网络效率等重要网络特性的影响.通过分析发现集装箱航运网络具有较好的鲁棒性,同时也具有较大的脆弱性.From the perspective of complex network, the Container Shipping Network was demonstrated to have character of scale free and small worlds. Through analyzing degree distribution, relation coefficient between degrees, and relation coefficient between degree and betweenness of the Container Shipping Network, the vertex with higher degree has more influence on the Container Shipping Network. So the node with higher degree is chosen as the target of attack firstly, and the random vertex is chosen as the target of error. Finally, another conclusion is drawn that the Container Shipping Network is robust but vulnerable by analyzing the change of clustering coefficient, average shortest path length, and network efficiency under errors and attacks.
