贸易与内生经济增长——基于中日数据的检验

Trade and Endogenous Growth——A Test with China and Japan's Data

贸易与内生经济增长理论的一个重要观点是出口产品种类的变化能够从某种程度上表示技术进步的变化,进而推动全要素生产率的提高。本文利用中国和日本1991-2006年的相关数据,检验了产品种类增加型的内生经济增长。采用贸易数据近似衡量产品种类变化的方法,估算了中国相对于日本的产品种类变化,以此作为解释变量进而对中日全要素生产率进行了实证分析,实证结果验证了贸易产品种类增加促进技术进步,进而推动全要素生产率提高的内生经济增长理论。

An important view of the trade and endogenous growth theory is that changes in flect to certain extent the change in total factor productivity. This paper employs data from export composition reChina and Japan between 1991 and 2006 to test endogenous growth with increased product variety. Relative changes in the variety of China＇s export products with respect to Japan is estimated approximately with trade data, and serve as the explained variable in testing the changes in China＇s relative total factor productivity. The empirical results confirm the theory that increased variety of exports will accelerate technological progress, and further enhance the total factor productivity.
