数字经济对区域创新能力的影响研究

Research on the Impact of Digital Economy on Regional Innovation Capability

伴随数字信息技术的发展及应用,数字经济已经成为推动经济新一轮发展的新兴力量。以2015—2019年我国30个省市的省际面板数据为研究样本,分别从数字经济基础水平、数字产业化和产业数字化三个维度构建数字经济发展指标体系,从创新的保障、投入、转化、产出四个方面构建区域创新能力指标体系,采用熵值法测度数字经济发展水平和区域创新能力,通过固定效应模型实证检验数字经济对区域创新的影响作用。研究结果表明:数字经济的发展能够显著提升区域创新能力;区域的对外开放程度越高,越有利于提升区域的创新能力。据此,提出优化并加强数字经济基础设施建设、加快推进产业数字化转型、完善数字经济治理体系等相关建议。

With the development and application of digital information technology,digital economy has become an emerging force to promote a new round of economic development.This paper takes the inter-provincial panel data of 30 provinces in China from 2015 to 2019 as the research sample,constructs the index system of digital economy development from three dimensions:digital economy foundation level,digital industrialization and industrial digitization,and constructs the index system of regional innovation ability from four aspects:innovation guarantee,input,transformation and output.The entropy method is used to measure the development level of digital economy and regional innovation ability,and the fixed effect model is used to empirically test the influence of digital economy on regional innovation.The results show that the development of digital economy can significantly improve regional innovation ability;the higher the degree of openness of the region,the more conducive to improving the regional innovation ability.Accordingly,this paper puts forward relevant suggestions such as optimizing and strengthening the construction of digital economy infrastructure,accelerating the digital transformation of industry,and improving the governance system of digital economy.
