Topological characteristics and community identification of container liner route network

As an important carrier of container liner transportation infrastructure, the quality of container liner route network affects the operation and development of shipping companies, and has a significant impact on communication and economic development between countries. Establish a container liner route network with ports as nodes and routes as edges, and analyze its topological characteristics and community structure. The results show that the container liner route network has small-world and scale-free characteristics, high global efficiency and extremely uneven distribution of port degree values. The size of network community has significant differences, and the distribution of ports has geographic clustering characteristics, but geographically neighboring ports may not be closely connected.
