R&D investment and regional innovation performance – threshold effects based on intellectual property protection

ABSTRACT Based on the panel data of 24 provinces and cities in China from 2009 to 2017, this paper uses panel threshold regression model with regional intellectual property protection intensity as the threshold variable to investigate the effect of R&D investment on regional innovation performance from two perspectives of human resource investment and R&D funding investment with different threshold effects. The results show that human resource investment and R&D investment have a significant contribution to regional innovation performance with a lag of three periods, and there is a significant double threshold effect. The optimal intellectual property protection intensity range of human resource input on regional innovation performance promotion is (0.8698, 0.8712). The optimal intellectual property protection intensity range for R&D investment on regional innovation performance is (0.8698, 0.8781), and R&D investment on regional innovation performance shows an increasing and then decreasing effect. This paper constructs a system of indicators to measure the intensity of intellectual property protection in China based on the “dual-track parallelism” of intellectual property protection management in China. It also measures the intensity of intellectual property protection in each region of China. A non-linear relationship between R&D investment, intellectual property protection and regional innovation is found.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
