Abstract In the process of economic integration in East Asia, the increasingly deepening industrial division of member countries leads to the changes in the product variety, which in turn affects the export trade mode and the formulation of trade policy. In order to clarify the changes in product variety and their impact on the export performance in East Asia during the process of regional economic integration, this paper calculates the export variety index in terms of biological variety index, and then use an expanded trade gravity model to test the impact of product variety on the export performance. Results show that a countrys product variety has a significant positive effect on its export trade, and the effects of trading partners product variety on export trade vary from industry to industry.
