Abstract: Global shipping network plays an important role in the import and export trade of the world, and its vulnerability directly affects the shipping trade between countries. It is significant to study the vulnerability of shipping network and ports. Firstly, this paper uses the theory and method of complex network to explore the topological structure characteristics of global shipping network. Then, combined with the structure characteristic of global shipping network, this paper analyzes the vulnerability of shipping network from two aspects：The key node identification and global vulnerability. Using MATLAB programming, this paper analyzes and calculates the vulnerability of each port and the vulnerability of global shipping network in two different attack modes. The results show that the efficiency of the network drops faster under the situation of the deliberate attack, namely the global container shipping network has a greater vulnerability in the face of deliberate attack, and prevention should be strengthened for vulnerable ports.

Key words: shipping network, complex network, vulnerability, network efficiency
