数字创新对企业技术创新效率提升的影响研究

Research on the Impact of Digital Innovation on Improving the Efficiency of Enterprise Technological Innovation

利用2014—2020年中国991家上市公司的面板数据,本文通过分别构建数字创新与技术创新效率两个评价指标体系,运用VAR模型实证分析数字创新及其影响。结果显示:数字创新整体上有利于制造企业技术创新效率的提升;数字创新不同基本要素影响也不同。进一步指出数字创新平台和数字创新文化对制造企业技术创新效率的影响前期具有滞后效应,数字技术、数字创新者和数字创新公民则呈现正负效应交替影响;数字创新基本要素加入的驱动效应优于传统生产要素投入的驱动效应。

Using panel data from 991 listed companies in China from 2014 to 2020,this article constructs two evaluation index systems for digital innovation and technological innovation efficiency,and empirically analyzes digital innovation and its impact using the VAR model.The results show that digital innovation is generally beneficial for improving the efficiency of technological innovation in manufacturing enterprises;The impact of different basic elements of digital innovation varies.Furthermore,it is pointed out that the impact of digital innovation platforms and digital innovation culture on the efficiency of technological innovation in manufacturing enterprises has a lag effect in the early stage,while digital technology,digital innovators,and digital innovation citizens exhibit alternating positive and negative effects;The driving effect of adding basic elements of digital innovation is better than the driving effect of traditional production factor investment.
