农业知识产权保护对绿色技术创新的空间溢出效应

Spatial Spillover Effect of Agricultural Intellectual Property Protection on Green Technology Innovation

文章选取2010—2019年中国31个省份农业知识产权保护、绿色技术创新、国际贸易、企业研发投入、外商直接投资等面板数据,利用空间杜宾模型实证考察农业知识产权保护与绿色技术创新的空间溢出效应及效应边界。研究结果表明,农业知识产权保护对绿色技术创新具有显著的空间溢出效应;农业知识产权保护对绿色技术创新的效应边界约为1240千米,超出这一边界则空间溢出效应基本不显著。因此,可通过提升农业知识产权保护水平、打造农业产业生态利益多元协同机制、强化区域间农业绿色技术创新联系方式,推动农业产业绿色技术创新发展。

This paper selects the panel data of agricultural intellectual property protection, green technology innovation,international trade, enterprise R&D investment and foreign direct investment in 31 provinces of China from 2010 to 2019, and empirically investigates the spatial spillover effect and effect boundary of agricultural intellectual property protection and green technology innovation by using spatial Dobbin model. The results show that agricultural intellectual property protection has a significant spatial spillover effect on green technology innovation. The effect boundary of agricultural intellectual property protection on green technology innovation is about 1240 km. Beyond this boundary, the spatial spillover effect is basically not significant. Therefore, it is suggested to promote the development of green technology innovation in agricultural industry by improving the protection level of agricultural intellectual property rights, creating a diversified coordination mechanism for ecological interests of agricultural industry, and strengthening the contact mode of agricultural green technology innovation among regions.
