国家知识产权战略对高技术产业创新效率的影响——基于时间断点回归设计

The Impact of China′s Intellectual Property Strategies on Innovation Efficiency of High-tech Industries:Regression Discontinuity in Time Design

在我国从知识产权大国向知识产权强国迈进的关键时期,探究实行国家知识产权战略对高技术产业创新效率的影响,既是推动高技术产业升级的有效手段,也是改革完善知识产权保护与管理制度的内在需求。基于2000—2019年中国28个省市地区高技术产业创新数据,运用时间断点回归方法检验中国实施国家知识产权战略对高技术产业创新效率的影响。研究表明:国家知识产权战略的实施在整体上显著促进高技术产业创新效率提升。区域异质性分析发现,战略实施显著提升了东、西部地区高技术产业的创新效率,但对中部地区创新效率的提升作用不显著。研究结论为优化知识产权政策设计、提高高技术产业的创新能力提供了经验证据。未来应进一步健全知识产权制度体系,并结合区域差异因地制宜制定知识产权政策。

In the critical period of China′s development from a country rich in intellectual property to one with powerful intellectual property protection,exploring the impact of intellectual property strategies on innovation efficiency of high-tech industries is not only an effective means to promote the upgrading of high-tech industries,but the internal demand for reforming and improving intellectual property protection and management system.Based on the data of high-tech industries in 28 provinces of China from 2000 to 2019,regression discontinuity in time design is used to test the impact of China′s intellectual property strategies on innovation efficiency of high-tech industries.The research shows that China′s intellectual property strategies overall have a significantly positive impact on innovation efficiency of the high-tech industries.Regional heterogeneity analysis finds that the implementation of the strategies significantly improves innovation efficiency of high-tech industries in the eastern and western regions but does not significantly improve innovation efficiency in the central regions.The research conclusion provides empirical evidence for optimizing intellectual property policies and improving the innovation of high-tech industries.
