Abstract:On the basis of constructing the cross - border e - commerce logistics network and the complex network theory, the invulnerability measure of the network is studied. Firstly, the paper analyzes the characteristics of the cross-border e - commerce logistics network by comparing with the cross-border logistics and e-commerce logistics, and constructs the cross-border e - commerce logistics network model. Then, it puts forward the invulnerability measure of the cross-border e - commerce logistics network: Network risk efficiency and the network loss efficiency. Finally, the invulnerability simulation analysis of the node and edge of the network is carried out by random damage and Intentional attack based on betweenness centrality. The experimental results show that the cross-border e - commerce logistics network is a typical scale-free network, and the impact of Intentional attacks on the network is greater than the random damage; And in network security maintenance, we need to pay attention to key nodes and edge security.
