摘要
为研究数字赋能下我国制造企业创新效率提升的有效途径,本文基于2015—2019年A股上市制造企业平衡面板数据,构建了一个超效率SBM-Tobit分析框架,检验数字赋能对制造企业创新效率的影响,并通过中介效应模型进一步揭示了其作用路径。结果显示:①在研究期间,样本企业创新效率具有由低到高的发展趋势,但企业间由于资源禀赋差异,存在“效率鸿沟”现象,造成整体效率均值处于较低水平;②数字赋能对制造企业创新效率提升具有显著的促进作用;③数字赋能可以通过成本和开放式创新中介变量促进制造企业创新效率提升。
Based on the balance panel data on Chinese listed manufacturing enterprises from 2015 to 2019,a super-efficiency SBM-Tobit analysis framework is constructed to study the effective ways to improve the innovation efficiency of Chinese manufacturing enterprises under digital empowerment,this paper examines the impact of digital empowerment on the innovation efficiency of manufacturing enterprises and further reveals its path by the intermediary effect model.The results show that:①during the study period,the innovation efficiency of sample enterprises has a trend from low to high,but there is a"efficiency gap"phenomenon among enterprises due to the difference of resource endowment,and the average of the whole efficiency is at a low level.②The digital empowerment can promote the innovation efficiency of the manufacturing enterprises.③Digital empowerment can promote the innovation efficiency of manufacturing enterprises through cost and open innovation variables.
