互联网发展对技术创新的影响研究——基于知识产权保护的视角

Research on the impact of Internet development on technological innovation from the perspective of intellectual property protection

创新是引领发展的第一动力,是推动高质量发展、建设现代化经济体系的重要战略支撑。基于2012—2019年我国233个地级市的面板数据,实证检验互联网发展对技术创新的线性和非线性影响,并构建以知识产权保护为门槛变量的面板门槛模型,探讨知识产权保护在互联网发展影响技术创新中的作用机理。研究结果表明:(1)线性分析发现,互联网发展对技术创新具有显著的线性促进作用;(2)非线性分析发现,互联网发展对技术创新存在一个由不显著到显著促进且边际效应递减的非线性关系,非线性关系更契合互联网的“齐普夫法则”;(3)门槛效应检验发现,互联网发展对技术创新的影响存在以知识产权保护为门槛的单门槛效应,随着知识产权保护跨过门槛值,互联网发展对技术创新的促进作用呈现逐渐增强的趋势;(4)异质性分析发现,互联网发展对东部和中部地区技术创新具有显著的促进作用,对西部地区的影响并不显著;同时,互联网发展对实用新型专利的促进作用最强,对外观设计专利的促进作用最弱。研究结果在理论层面明晰了互联网发展、知识产权保护对技术创新的影响机理和作用机制,在实践层面为区域创新主体在合理的知识产权保护水平下发挥互联网技术优势实现创新驱动发展提供了理论借鉴和决策支持。

Innovation is the first driving force for development and it is also an important strategic support for promoting high-quality development and building a modern 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 relationship from insignificant to significant promotion and decreasing marginal effect of Internet development on technological innovation,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 intellectual 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 promotion effect on utility model patents and the weakest promotion effect on design patents.The research results clarified the theoretical 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 advantages of Internet technology under reasonable intellectual property protection levels so as to achieve innovation-driven development.
