The Impact of Product Variety on the Export Performance in East Asia

在东亚经济一体化进程中,各国产业分工的日益深化使得产品多样性发生了改变,并影响区域内各国贸易模式和贸易政策的制定。从对总样本的分析来看,本国的产品多样性对出口贸易的影响显著为正,而贸易对象国的产品多样性对出口贸易的影响各产业存在差异。在进行东亚经济一体化过程中,可以根据不同产业产品多样性对出口绩效影响的不同分别制定贸易和产业政策,从而更加有效地推进东亚区域经济一体化的进程。

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 country s 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.
