摘要
数字经济是新时代中国推动绿色创新,实现高质量发展的重要驱动力,探究数字经济发展对绿色创新效率的影响具有重要的现实意义。本文基于2012~2021年我国30个省份的面板数据,构建双向固定效应模型,实证分析了数字经济发展对绿色创新效率的影响作用。研究发现:数字经济发展水平与绿色创新效率呈显著的“先抑制后促进”的U型关系,并且存在地区异质性;研发投入强度对数字经济发展和绿色创新效率之间的关系具有调节作用。随着调节变量的增大,U型曲线拐点右移,同时U型曲线变得平缓。综合上述结论,本文给出相应政策建议。
Digital economy is an important driving force for China to promote green innovation in the new era.It is of great practical significance to explore the impact of digital economy on green innovation efficiency.Based on the panel data of 30 provinces in China from 2012 to 2021,this paper constructs a two-way fixed effect model to demonstrate the influence of digital economy on green innovation efficiency.It is found that there is a significant U-shaped relationship between the level of digital economy and the efficiency of green innovation,and there is regional heterogeneity;R&D investment intensity can regulate the relationship between digital economy and green innovation efficiency.With the increase of regulating variables,the inflection point of U-shaped curve moves to the right and the U-shaped curve becomes flatter.Based on the above conclusions,this paper gives corresponding policy suggestions.
