国际专利保护对中国专利密集型商品出口的影响研究

The Effects of International Patent Rights Protection on China's Patent-sensitive Commodities

对国外专利保护对中国专利密集型商品出口的影响进行经验分析,结果表明,在与中等模仿能力和弱模仿能力国家进行贸易时,国外专利保护会通过市场扩张效应,提高中国专利密集型商品的出口;而在与强模仿能力国家进行贸易时,国外专利保护对中国专利敏感型商品出口没有显著影响。随着中国专利技术含量的提高,国外专利保护对中国专利密集型商品出口的影响的统计显著性日益提高;与TRIPS协议签订之前相比,协议签订后,国外专利保护对中国专利密集型商品的效应有着显著的变化,而这一变化在商品水平上呈现较大差异。

This article analyzes the effects of patent rights on China's patent-sensitive commodities using the Gravity Model and panel data from 1990 to 2007. The findings show that strong foreign patent rights stimulate the exports of China's patentsensitive commodities through the market expansion effect across countries with moderate and weak imitative abilities. However,it is found that the strength of patent rights is irrelevant with China's patent-sensitive commodities across counties with strong imitative ability. The findings also show that China's patent-sensitive commodities are increasingly "patent-related"in recent years. In addition,after the assignment of the TRIPS agreement,the effects of patent rights on China's patent-sensitive commodities deviate from before,which further vary across different commodities.
