知识产权保护与中国企业进口产品质量

Intellectual Property Rights and Import Quality of Chinese Firms

理论上进口地区知识产权保护加强会促进新产品的进口,但对进口产品质量的影响方向不确定,新产品的质量可能会高于或低于知识产权保护之前的进口产品质量。基于中国企业微观数据的分析结果表明:中国进口地区加强知识产权保护会扩展外国企业出口产品的种类范围,进口地区会进口新的产品品种,但新品种的质量水平低于持续进口产品,从而拉低了进口产品质量的平均水平;进口地区知识产权保护加强,仅对中等技术产品的进口产品质量影响显著,对高、低技术产品的进口产品质量影响都不显著。此外,进口地区加强知识产权保护,显著促进了中等技术产品中的中等质量品种进口规模。

This paper theoretically analyses the impact of intellectual property rights(IPRs)protection on the quality of imported products,empirically analysing this using Chinese enterprise micro-data.The results of the study show that:(i)increased IPRs protection in importing regions encourages foreign enterprises to start exporting a wider range of product varieties and incentivizes Chinese enterprises to import these new varieties,however,the quality of these is lower than that of the commonly imported varieties,thereby reducing the average level of imported product quality;(ii)the effects of increased IPRs protection on the quality of imported medium-tech products are significant,while they are unobservable on high-and low-tech products;and(iii)an additional study notes that with increased IPRs protection,mid-quality varieties import of medium-tech products rises significantly.
