数字经济对企业碳排放强度的影响研究——基于绿色技术创新的中介效应

Research on the Impact of Digital Economy tothe Carbon Emission Intensity of Enterprises—Based on the Mediating Effect of Green Technology Innovation

在“双碳”目标导向下,数字经济发展持续推动企业进行碳减排。基于2012—2021年我国沪深A股工业上市公司相关数据,研究采用面板固定效应模型实证检验数字经济对企业碳排放强度的影响。研究结果表明,数字经济发展能显著降低企业碳排放强度,企业绿色技术创新在数字经济影响企业碳排放强度中发挥中介作用。异质性分析发现,数字经济对西部地区企业、重污染企业及国有企业碳排放强度的影响更显著。持续推进数字经济发展、提高企业绿色技术创新水平和社会责任意识对降低企业碳排放强度有积极意义。

Under the guidance of the"dual carbon goals",the development of the digital economy continues to promote corporate carbon emission reduction.The study is based on relevant data of industrial listed companies in China's Shanghai and Shenzhen A-shares from 2012 to 2021,and uses a panel fixed effects model to empirically test the impact of the digital economy on the carbon emission intensity of enterprises.The research results indicate that the development of digital economy can significantly reduce the carbon emission intensity of enterprises,and green technology innovation of enterprises plays a mediating role in the impact of digital economy on the carbon emission intensity of enterprises.Heterogeneity analysis found that the digital economy has a more significant impact on the carbon emission intensity of regional enterprises,heavily polluting enterprises,and state-owned enterprises in the western region.Continuously promoting the development of the digital economy,improving the level of green technology innovation and social responsibility awareness of enterprises have positive significance in reducing their carbon emission intensity.
