摘要
采用中国沪深A股上市企业2008—2018年的面板数据,实证分析了专利权行政保护力度对关键技术创新及全要素生产率增长的影响。研究表明:总体来看,加强专利权行政保护力度有利于企业的关键技术创新及全要素生产率增长;分样本结果显示,加强专利权行政保护力度对国企、中小规模企业及低技术企业关键技术创新及全要素生产率增长的促进作用更大;影响机制分析表明,专利权行政保护通过吸引外商直接投资促进关键技术创新,从而进一步提升全要素生产率。
Based on the panel data of Chinese A-share listed companies in Shanghai and Shenzhen from 2008 to 2018,this paper empirically analyzes the impact of patent administrative protection on key technology innovation and total factor productivity growth.The study shows that,on the whole,strengthening the administrative protection of patent rights is beneficial to the key technological innovation and total factor productivity growth of enterprises.The sub-sample results show that strengthening the administrative protection of patent rights plays a more important role in promoting the key technological innovation and total factor productivity growth of state-owned enterprises,small and medium-sized enterprises and low-tech enterprises.The analysis of the influence mechanism shows that patent administrative protection promotes key technological innovation by attracting foreign direct investment,thus further improving total factor productivity.
