The gravity model of trade in international economics, similar to other gravity models in social science, predicts bilateral trade flows based on the economic sizes of (often using GDP measurements) and distance between two units. The model was first used by Walter Isard in 1954. The basic theoretical model for trade between two countries (i and j) takes the form of:

Where F is the trade flow, M is the economic mass of each country, D is the distance and G is a constant. The model has also been used in international relations to evaluate the impact of treaties and alliances on trade, and it has been used to test the effectiveness of trade agreements and organizations such as the North American Free Trade Agreement (NAFTA) and the World Trade Organization (WTO).

我之前在准备材料时看到了一点相关内容，供楼主参考：贸易引力模型指出，两国或地区之间的双边贸易额与这两个国家或地区的经济总量成正比，于两者之间的空间距离成反比。经济学家常用类似的贸易引力模型说明部门内贸易流量与流向的决定问题。比如，目前我国已达成的自由贸易区都是在我国周边地区的，具有很强的地缘性。这个就符合贸易引力模型。
