中文摘要：
基于复杂网络理论,构建以港口间海运距离和吸引度为基础的复杂网络演化模型。选取全球25个主要集装箱港口2010年相关数据,对比演化网络、实际网络和同等规模的随机网络,验证了模型的有效性。将模型应用于北极航线通航后的海运网络,结果显示,北极航线通航后海运网络平均路径长度减小,表明北极航线开通加强了港口间的联系;部分东北亚及西北欧港口度值增加较为明显;港口核度更趋于极化,表明北极航线增强了海运网络的层次性。
英文摘要：
Based on the complex network theory,a complex network evolution model is set up on the basis of the distance and the attraction between ports.We select relevant data of 25 world main container ports in 2010,compared evolution network,practical network and the same size random network and verify the validity of the model.Then apply the model to the world shipping network under the arctic route,the results showed that the average path length decreases suggests that the open of arctic routes strengthen the contract between ports;degree value of part of northeast Asia and northwest Europe ports increase obviously;the value of k-core of ports tend to be more polarized.It suggests that the arctic route can enhance the network of gradation of shipping.
