信息基础设施投入对全要素生产率的影响

Research on the Influence of Information Infrastructure Investment on Total Factor Productivity

信息基础设施已经成为新时期我国经济社会发展的战略性公共基础设施,高质量发展背景下,经济发展效率成为当下关注的热点。因此,文章在技术创新视角下,通过中介效应模型,利用2006-2017年中国30个省级面板数据,探讨了信息基础设施对全要素生产率的影响以及信息基础设施通过技术创新影响全要素生产率的作用机制。研究结果表明,各地区信息基础设施投入都对全要素生产率具有显著且正向的促进作用,但信息基础设施投入的促进作用在不同地区有所差异。另外信息基础设施能够通过促进技术创新来提高全要素生产率,并且这一结果也随着地区的不同呈现出差异性。东部与中部地区信息基础设施都能够通过技术创新来促进全要素生产率,而在西部地区,技术创新的中介效应不适用。

Information infrastructure has become the strategic public infrastructure for China’s economic and social development in the new era.Under the background of high-quality development,economic development efficiency has become the focus of current attention.Therefore,from the perspective of technological innovation,this paper discusses the influence of information infrastructure on total factor productivity and the mechanism of information infrastructure’s influence on total factor productivity through technological innovation by using the mediating effect model and the panel data of 30 provincial level in China from 2006 to 2017.The results show that information infrastructure investment has a significant and positive promotion effect on total factor productivity in all regions,but the promotion effect of information infrastructure investment is different in different regions.In addition,information infrastructure can improve total factor productivity by promoting technological innovation,and the results vary from region to region.Information infrastructure in eastern and central regions can promote TFP through technological innovation,while the mediating effect of technological innovation is not applicable in western regions.
