In order to reveal the characterristics of the shipping route network and evaluate the effect of ports failure on connectivity of network, the structure of shipping route network was analyzed based on complex network theory, and the connectivity of network under different failure patterns was studied. Results show that the shipping route network has a smaller average path length and a larger cluster coefficient at the same time, which has small-world effect, and the match between degree distribution and exponential distribution is better, which has the characteristic of scale-free property. The shipping route network invulnerability is robust under random failure and the connectivity is poor under selective failure. The study indicates that few hub ports play a key role on the shipping route network’s connectivity, which should be ensured on normal and efficient operation. And the structure of shipping route network need to be improved by intensifying the connection between the hub ports and general ports.
