Abstract: Intellectual property friction has been upgraded to the focus of China's foreign trade friction. This article based on the extended gravity model which the Bergstrand constructed, empirical study the impact of intellectual property protection on China’s services import. The results show that market expansion effect is greater than market power effects, intellectual property protection promote the China's services imports. In addition, the effect of intellectual property protection in the industry presents some differences, it has significant positive impact on six sectors’s imports in 10 service industries, the high-tech services more responsive to intellectual property protection; the impact coefficient of three sectors is positive, but not significance; while the significantly negative impact exist in communications imports.

摘要： 知识产权摩擦已经升级为我国对外贸易摩擦的重点。文章在扩展Bergstrand（1989）双边贸易引力模型的基础上，基于2000-2011年间我国服务业总体和细分行业的进口数据，实证检验了加强知识产权保护对服务贸易进口的影响。结果表明，知识产权保护的市场扩张效应大于市场势力效应，总体上促进了我国的服务贸易进口。此外，知识产权保护的进口效应呈现了一定的行业差异，对10个服务行业中的6个行业进口存在显著积极的影响，其中高技术服务业的进口对知识产权保护的反应更为敏感；对其中3个行业的影响系数为正，但没有通过显著性检验；而对通讯服务进口存在显著地消极影响。
