Topology analysis of china's port shipping network

Based on China's port shipping statistical data from 2006 to 2010, the paper constructs China's port shipping network structure chart, and analyzes the degree distribution, average path length, network density and network clustering coefficient of the network. The results show that China's port shipping network has scale-free characteristic with short average path length, high network density, and its degree distribution follows a power law. Through the computer simulation, the higher correlation coefficient also shows that data fitting is satisfactory, which further validates that China's port shipping network is a scale-free network. © 2013 Academy Publisher.
