Innovation is the first driving force for development and it is also an important strategic support for promoting high-quality development and building a modem economic system.Based on the panel data of 233 prefecture-level cities in China from 2012-2019,we empirically tested the linear and nonlinear effects of Internet development on technological innovation,and constructed a panel threshold model with intellectual property protection as the threshold variable to explore the mechanism of the role of intellectual property protection in Internet development affecting technological innovation.The linear analysis finds that(1)Internet development has a significant linear promotion effect on technological innovation;(2)there is a non-linear rela-tionship from insignificant to significant promotion and decreasing marginal effect of Internet development on technological innova-tion,and the non-linear relationship is more consistent with the"Zipf's law"of the Internet;(3)there is a single threshold effect of Internet development on technological innovation with intellectual property protection as the threshold,and after intellec-tual property protection crosses the threshold,the promotion effect of Internet development on technological innovation shows a gradually increasing trend;and(4)Internet development has a significant promotion effect on technological innovation in the eastern and central regions,but not significantly on western regions;meanwhile,Internet development has the strongest promo-tion effect on utility model patents and the weakest promotion effect on design patents.The research results clarified the theoreti-cal mechanism and action mechanism of the impact of Internet development and intellectual property protection on technological innovation,and it will provide some theoretical reference and decision support for regional innovation entities to leverage the ad-vantages of Internet technology under reasonable intellectual property protection levels so as to achieve innovation-driven devel-opment.
