数字经济与企业绿色全要素生产率——多元协同视角下有调节的中介机制分析

Study on the impact of digital economy on green total factor productivity of enterprises——Analysis of mediating mechanism with adjustment from the perspective of multiple collaboration

近年来,数字经济已成为经济发展的核心动力,对推动绿色高质量发展具有重要意义。利用2011—2021年中国A股上市公司面板数据集,基于多元协同视角,建立了有调节的中介效应模型,探究数字经济对企业绿色全要素生产率的影响及其作用机制。研究发现,数字经济发展显著提升了企业绿色全要素生产率水平,且结论在经过选取历史数据作为工具变量和将“国家大数据综合实验区”的设立作为外生政策冲击等稳健性检验后仍然成立。绿色技术创新在此过程中发挥中介作用,且影响机制受到政府环保支持与公众环境关注的正向调节。进一步分析发现,数字经济对企业绿色全要素生产率的促进作用在环境规制强度更高的地区、劳动与技术密集型行业和非重污染行业及国有企业中更显著。同时,揭示了数字经济与企业绿色全要素生产率的内在联系,构建了一条绿色高质量发展的多元协同路径。

In recent years,the digital economy has become the core driving force of economic development,which is of great significance for promoting green and high-quality development.Based on the panel data set of China's A-share listed companies from 2011 to 2021,this paper establishes A moderated intermediary effect model based on the perspective of multiple collaboration to explore the impact of digital economy on green total factor productivity of enterprises and its mechanism.It is found that the development of digital economy significantly improves the level of green total factor productivity of enterprises,and the conclusion is still valid after the robustness test,such as the selection of historical data as the instrumental variable and the establishment of“National big Data comprehensive experimental area”as the exogenous policy impact.Green technology innovation plays an intermediary role in this process,and the influence mechanism is positively regulated by government environmental protection support and public environmental concern.Further analysis shows that the promotion effect of digital economy on green total factor productivity of enterprises is more significant in areas with higher environmental regulation intensity,labor-and technology-intensive industries,non-heavy polluting industries and state-owned enterprises.At the same time,the internal connection between digital economy and enterprise green total factor productivity,and constructs a multi-collaborative path of green and high-quality development.
