Abstract: A two-dimensional evaluation system is constructed based on the connotation of regional greoi innovation performance. Based on the Chinese provincial panel data from 2009 to 2017, the Super-SBM model is used to measure the green innovation performance of each region. The protection of intellectual property rights on regional green through the intermediary model and the impact of innovation performance and its action path are explored. The results show that the increase in the intensity of intellectual property protection will positively affect the efficiency and effectivoiess of regional green innovation through research and development investment. In addition, the effect of human resources investment in research and development investment is stronger than the effect of research and development investment. Moreover, the intensity of intellectual property protection has a more significant impact on the efficiency of regional green innovation than the efficiency of regional greoi innovation. Intellectual property protection has a non-linear impact on the efficiency of regional green innovation? and there is an "optimal protection interval". Furthermore, there is an obvious heterogeneity in the regional greoi innovation performance in China, and most regions are in the range of low green innovation efficiency and low green innovation benefit.

Key words: intellectual property protection, regional green innovation performance, research and development investment

摘要： 从区域绿色创新绩效内涵出发构建二维评价体系，基于2009~2017年中国省级面板数据，运用Super-SBM模型对各区域绿色创新绩效进行测度，并通过中介效应模型探究知识产权保护对区域缘色创新绩效的影响及其作用路径。研究结果表明：知识产权保护的增加会通过R&D投入正向影响区域绿色创新效率与效益；R&D投入中人力资源投入对区域创新绩效的作用效果强于研发经費投入效果；知识产权保护对区域绿色创新效益的影响较区域绿色创新效率更为显著，知识产权保护对区域缘色创新效益具有非线性影响，存在最优保护区间；中国区域绿色创新绩效存在明显的异质性，多数地区处于低绿色创新效率与低绿色创新效益区间。
