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