Abstract: Considering the influencing factors such as the economic scale,the number of Chinese ports and the exchange rate of the two countries,this paper comparatively analyzed the trade data of forest products between China and Japan from 2000 to 2021 through the interpretation of the traditional gravitational model. It put forward relevant suggestions to increase the economic scale,to expand the number of labor force and to ensure the stability of the exchange rate. Through the specific study of forest product trade between China and Japan,it’s helpful to put forward reasonable suggestions for the formulation of China’s foreign forest products trade policy after the establishment of RCEP.
