数字经济赋能工业创新的机理及效应研究——基于工业创新活动的技术效率和技术进步视角

Study on the Mechanism and Effects of Digital Economy Empowering Industrial Innovation--From the Perspective of Technical Efficiency and Progress in Industrial Innovation Activities

基于工业创新活动的技术效率和技术进步视角,文章分析了数字经济赋能工业创新的理论逻辑,并基于2011—2019年工业企业省级面板数据,采用工具变量法实证检验了数字经济发展对工业创新的赋能效应。理论分析表明,数字经济发展不仅可以促进创新资源的优化配置,还可以改进创新活动的技术手段,表现为可同时提高工业创新活动的技术效率和技术进步。实证结果发现,数字经济发展对工业创新活动的全要素生产率、技术效率和技术进步都具有促进作用,这意味着数字经济发展可通过工业创新活动的技术效率渠道和技术进步渠道提高工业创新活动效率;此外,影响系数的大小显示两种渠道的作用大体相当。因此,可以采取措施进一步促进数字经济发展和企业创新活动数字化转型,以破解制造业发展面临的困境和全面塑造发展新优势。

Based on the perspective of technical efficiency and technological progress during industrial innovation activities,this paper analyzes the theoretical logic of digital economy enabling industrial innovation,and empirically tests the enabling effect of digital economy development on industrial innovation based on the provincial panel data of industrial enterprises from 2011 to 2019 by using the instrumental variable method.This paper analyzes the theoretical logic of digital economy empowering industrial innovation from the perspective of technical efficiency and progress in industrial innovation activities and empirically tests the empowerment effect of digital economy development on industrial innovation efficiency by using instrumental variable method based on the provincial panel data of industrial enterprises from 2011 to 2019.Theoretical analysis shows that the development of digital economy can not only promote the allocation of innovation resources,but also improve the technical means of innovation practices,which means that it can improve the technical efficiency and technical progress of industrial innovation at the same time.The empirical results show that the development of digital economy can promote the total factor productivity,technical efficiency and technical progress of industrial innovation activities,which means that the development of digital economy can improve the efficiency of industrial innovation through the technical progress channel and technical efficiency channel.In addition,the size of influence coefficients shows that effects of the two channels are generally the same.Therefore,measures can be taken to further strengthen the development of digital economy and the digital transformation of enterprise’innovation activities so as to resolve the development difficulties faced by the of manufacturing industry and create new development strengths.
