The Port of Gwangyang was built with the aim of reducing congestion at the Port of Busan by acting as sub-hub port. Many studies have discussed the new port construction and dual-hub port system to solve the increasing demand and port congestion problems; however, there is not much research discussing the sub-hub port system. As such, the main purpose of this paper is to analyze the liner shipping network structure of the sub-hub-oriented Port of Gwangyang using social network analysis (SNA). In terms of number of connections among ports, using in-degree, out-degree, and betweenness centrality, Busan is the most important port in Gwangyang's network. However, when it comes to considering the influence of ports using hub centrality, Busan drops to the fifth most influential position. In the network of the Port of Gwangyang, Shanghai and Hong Kong have more important roles compared to those of the Port of Busan.
