为探究港口的影响能力，构建了全球集装箱海运有向加权网络，在传统复杂网络中心性研究的基础上，融入有效距离的概念计算全球集装箱海运加权网络接近中心性，比较分析港口部分影响因素、拓扑结构和港口吞吐量与基于有效距离的接近中心性之间的关系.研究结果表明：代入有效距离概念计算接近中心性得到的结果更具有现实意义;使用该方法找出的中心港口具有地理、经济区位与软环境上的优势；吞吐量增量具有反映港口影响力的能力.通过有效距离中心性研究方法找出的关键港口可以作为网络中转枢纽，由此可缩短运输距离，减少成本，拉动外贸需求，进而带动周边港口及城市发展，形成区域化经济带.

A directed and weighted global container shipping network was constructed in order to explore the ports influence. Based on the study of centrality of traditional complex network, the concept of effective distance was integrated to calculate the closeness centrality of global container shipping weighted network as well as analyze and compare the relationships between the influencing factors of ports, topology structure, ports capacities and closeness centrality based on effective distance. Results show that the results calculated with effective distance are more consistent with the real network, and the central port identified by using this method has advantages of geography, economic location and soft environment, and the port throughput increment can reflect port influence. The key ports identified by the effective distance centrality method can be served as network transit hub, which can shorten the transportation distance, reduce cost, and pull up foreign trade demand, and then drive the development of the surrounding ports and form a regional economic zone.
