"21世纪海上丝绸之路"沿线港口地位综合评价

Comprehensive Evaluation of the Positions of the Ports along“21Maritime Silk Road”

本文基于复杂网络节点重要性分析方法,从海运网络分析的视角对"21世纪海上丝绸之路"沿线港口参与"一带一路"建设的地位进行评价.在收集海上丝绸之路沿线102个港口实际数据的基础上,构建海上丝绸之路海运网络拓扑结构图.通过对网络中港口节点的度中心性、接近中心性、中介中心性、特征向量中心性指标进行计算,结合熵权TOPSIS法综合得到港口地位的排序.结果表明新加坡港、上海港、巴生港在网络中具有很高的地位,且现有的复杂网络节点重要性排序方法存在局限,基于熵权TOPSIS法的综合评价得到的港口排序更符合实际发展需求.最后运用节点删除法对排序结果进一步分析,为中国港口参与"一带一路"建设提供参考与建议.

Based on the centrality indicators for node importance from complex network,this paper evaluates the positions of ports along“21 Maritime Silk Road”which participate in the construction of“Belt and Road Initia-tive”from the perspective of shipping network.Collecting the data of 102 ports along Maritime Silk Road,we construct the shipping network topology diagram of the ports and get the ranking of port positions by calculating degree centrality,closeness centrality,betweenness centrality and feature vector centrality combined with the method of Entropy-weight TOPSIS.The results show that Singapore port,Shanghai port and Klang port have high positions in“21Maritime Silk Road”shipping network.And existing complex network method of node importance ranking contains some limitations while the comprehensive evaluation method based on Entropy-weight TOPSIS is more realistic.In addition,node deletion method is used to analyze the results,and suggestions are put forward for Chinese ports in the construction of“Belt and Road Initiative”.
