企业数字化转型、绿色创新与碳绩效——碳排放权交易政策与公众环境关注度的调节作用

随着数字经济的迅猛发展，利用数字化优势助力企业绿色转型已成为“双碳”背景下的必然趋势。从利益相关者理论和信号理论出发，以2014—2020年中国沪深A股上市工业企业为样本，实证检验了企业数字化转型能否提升碳绩效，并探讨了绿色创新在其中的中介作用以及碳排放权交易政策和公众环境关注度的调节作用。研究发现，企业数字化转型显著提升了碳绩效，并通过绿色创新正向影响企业碳绩效水平。同时，碳排放权交易政策与公众环境关注度均能发挥显著的正向调节效应。异质性分析显示，企业数字化转型对碳绩效的促进作用在非高新技术企业和高市场竞争程度的情境下更为明显，但产权性质的影响并不显著。研究结论厘清了企业通过数字化转型促进绿色创新进而提升碳绩效的驱动机制，为推进企业数字化转型以实现绿色发展具有重要参考意义。

Enterprise Digital Transformation, Green Innovation and Carbon Performance—Moderating Effects of Carbon Emissions Trading Policy and Public Environmental Concern

With the rapid development of the digital economy， utilizing digital advantages to assist enterprises in green transformation has become an inevitable trend in the context of “carbon peak and neutrality”. Based on stakeholder theory and signal theory， it took Chinese A-share listed industrial enterprises on Shanghai and Shenzhen stock exchange from 2014 to 2020 as samples to empirically test whether the digital transformation of enterprises can improve carbon performance， and discussed the mediating effect of green innovation， as well as the moderating effects of carbon emissions trading policy and public environmental concern. It shows that the digital transformation of enterprises has a significant positive impact on carbon performance， and positively affects the level of carbon performance of enterprises through green innovation. At the same time， both carbon emissions trading policy and public environmental concern play positive moderating effects. Heterogeneity test shows that the promotion of digital transformation of enterprises on carbon performance is more significant in the context of non high-tech enterprises and high market competition intensity， but the impact of the nature of enterprise property rights is not significant. The research conclusion clarifies the driving mechanism of digital transformation in promoting green innovation and improving carbon performance， which has important reference significance for promoting digital transformation of enterprises to achieve green development.
