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.
