Abstract: Competition among the ports is not only the competition for the supply of land to the hinterland but also that to the foreland, especially contending for shipping routes. Therefore, the routes become a kind of important data for statistical analyzing, which can visualize the shipping network and perform the statistical change of Ports by social network analysis software, such as Gephi and Arcgis. This paper chooses Shanghai port and Ningbo port as the cases to analyze and compare, the results as follows: 1) The network centrality and betweenness centrality of Shanghai Port are highest in China shipping network in recent years, those indexes of Ningbo Port are ranked the second, only behind Shanghai in mainland China.2) The port coverage of two ports continue to enlarge. Shanghai port is larger than Ningbo ports in the port coverage of near-sea shipping line, but Ningbo port is nearly close to Shanghai port in the port coverage of ocean shipping line to Mediterranean Sea, north-western Europe , South Asia, North America, South America and Africa.3) The primate ports are almost same which have close connectivity with Ningbo port and Shanghai port in each navigation areas, but the main connection between Shanghai port and Eastern America such as New York port has been replaced by the connection between Ningbo port and Eastern America port since 2015.
