Topology Analysis of China's Port Shipping Network

摘要

Based on China's port shipping statistical datafrom 2006 to 2010, the paper constructs China's portshipping network structure chart, and analyzes the degreedistribution, average path length, network density andnetwork clustering coefficient of the network. The resultsshow that China's port shipping network has scale-freecharacteristic with short average path length, high networkdensity, and its degree distribution follows a power law.Through the computer simulation, the higher correlationcoefficient also shows that data fitting is satisfactory, whichfurther validates that China’s port shipping network is ascale-free network.
