Demonstration Test and Potential Analysis Based on Gravity Model of Logistics Cooperation among China, Japan and Korea

Gravity model is an important method for the analysis of international trade. China, Japan and Korea have founded perfect logistics cooperation. In order to confirm the economic rationality of the three countries' logistics cooperation, it is necessary to build a model of China-Japan-Korea logistics cooperation in the economic effectiveness and the impact model via gravity model, and analysis the possible causes and effects of the trade effectiveness among three countries. At the same time, establish a tendency model of the trade quantity to predict potential of the logistics cooperation. The demonstration test shows that the cooperation is beneficial to the three countries' economic welfare and a huge potential in the logistics cooperation among three countries not only can achieve a win-win situation, but also ultimately provide theoretical and technological contributions in constituting regional economic integration of the Northeast Asia.
