摘　　要：选用2002—2015年中国与31个贸易伙伴国(地区)高技术产品的双边贸易数据,采用Hummels等(2005)的方法将中国高技术产品的出口分解为三元边际,即扩展边际、数量边际和价格边际,实证分析了进口国加强知识产权保护对中国高技术产品出口增长三元边际的影响。结果表明:进口国加强知识产权保护对中国高技术产品出口的扩展边际和价格边际均产生正向影响,即有利于促进中国高技术产品出口种类的多样化并提高出口价格;但进口国知识产权保护的增强反而会减少中国高技术产品出口的数量边际,不利于出口数量的增加。因此,中国应完善知识产权保护制度、增强自主创新能力,以促进高技术产品出口的健康持续稳定增长。Using the bilateral trade data of China＇ s high-tech products export to 31 trading partner countries （regions） between the years of 2002 and 2015, this paper refers to the decomposition method of Hummels and Klenow （2005） and decomposes the export of high- tech products into a ternary-margin framework, including extensive margin, quantity margin and price margin. Then the paper empiri- cally analyzes the effect of intellectual property protection on the three margins of China＇ s high-tech products exports. The results show that strengthening the intellectual property protection in import countries has a positive impact on both the extensive margin and price margin, which is conducive to the diversity of China＇ s high-tech products exports and the rise of export price. However, it will reduce the quantity margin of China＇ s export of high-tech products, which will hinder the increase of export quantities. Therefore, China should improve the intellectual property protection system and enhance the capacity for independent innovation to promote the healthy and sustained growth of high-tech product exports.
