To promote the efficiency of the archipelago shipping logistics network, a three-level model based on the hub-spoke network is put forward. Seven indices, which are analyzed by principal component analysis method, are selected to determine the level of logistics nodes in shipping logistics network. With an archipelago in the south of China as applying background, the index system is used to determine the ranking of the islands and the three-level shipping logistics network is constructed. The result shows that: the three- level shipping logistics network can promote the scale benefit and save the logistics cost; the islands in archipelago can be divided into three levels by the index system to assist the layout planning of archipelago shipping logistics network.
