Abstract: This paper reviews the related research of international trade network. Firstly, the paper presents a brief introduction to models of the international trade network:classic network model, fitness model, hyperbolic model, flow network model, multi-layer network model and bipartite network model. Subsequently, the research on the international trade network is reviewed from four aspects:statistical characteristics, community structure, evolution model and dynamic behavior. Finally, the research on international trade network is briefly summarized and some future directions are pointed out.
