国际贸易是技术转移与溢出的主要渠道之一,对于创新能力亟待提高而贸易规模已跃居世界首位的中国尤其值得重视。制药产业与知识产权存在紧密联系,但南北国家对该行业知识产权制度的实施仍存在较大争议。以贸易的技术溢出为切入点,通过岭回归分析,探索知识产权制度对中国制药产业技术进步的影响。研究发现,知识产权制度体系的建设与完善有利于中国制药产业实现技术进步。未来,中国应实施适宜的保护强度以加速提升本土企业创新能力,促进经济增长。 International trade is one of the main channels for technology transfer and spillover. It is especially worth noting that China, whose innovation capability needs to be enhanced and whose trade scale has topped the world rank. There is a close relationship between the pharmaceutical industry and intellectual property rights. However, there is still much controversy over the implementation of the intellectual property system in the industry between the two countries. Based on the technological spillover of trade, we analyzed the impact of intellectual property system on the technological progress of China’s pharmaceutical industry through ridge regression analysis. The study found that the construction and improvement of intellectual property system is conducive to China’s pharmaceutical industry to achieve technological progress. In the future, China should implement appropriate intensity of protection in order to speed up the innovation capability of local enterprises and promote economic growth.
