互联网、金融发展与科技创新

Internet,Financial Development and Science&Technology Innovation

基于2008—2017年中国省级面板数据,建立门槛模型探讨了互联网影响科技创新的非线性传导机制。研究结果表明:互联网能够通过金融发展促进科技创新。互联网基建水平对科技创新影响的直接效应大于间接效应;互联网的使用水平在金融发展水平较低的地区对科技创新产出有一定的抑制作用,而在金融发展水平较高的地区对科技创新产出具有促进作用;互联网基础建设水平对科技创新在不同金融发展水平地区均呈现出显著的积极作用,但对金融发展水平较低地区的科技创新促进作用较小,对金融发展水平较高地区的促进作用较大。因此,互联网虽从整体上提高了科技创新产出,但也拉大了金融发展水平不同的地区之间的创新产出差距。

Based on the provincial panel data of China from 2008 to 2017,this paper constructs a threshold model to explore the nonlinear transmission mechanism of the impact of the internet on science and technology innovation.The results show that the Internet can promote regional science and technology innovation through financial development,and the direct effect of the level of Internet infrastructure on science and technology innovation is greater than that of the indirect effect.The level of using Internet has a certain inhibitory effect on the output of science and technology innovation in regions with low level of financial development,while it has a positive effect on the output of science and technology innovation in regions with higher level of financial development.The level of Internet infrastructure plays a positive role on science and technology innovation in regions with different levels of financial development,but it has a smaller effect on promoting scientific and technological innovation in regions with lower levels of financial development and a greater effect on those regions with higher levels of financial development.Therefore,although the Internet has improved the output of science and technology innovation as a whole,it has also widened the gap of innovation output between regions with different levels of financial development.
