摘　　要：【目的】数字化转型为制造业企业节能减排提供了契机。厘清数字化转型对企业污染排放的影响和作用路径对推动经济高质量发展具有重要的政策启示。【方法】本文聚焦制造业企业污染排放,基于中国工业企业数据库、中国工业企业污染排放数据库和世界投入产出表等3个数据库的匹配数据,综合采用固定效应模型、调节效应模型以及工具变量法,考察了数字化转型对制造业企业污染排放的影响及其作用机制。【结果】实证结果表明,数字化转型能够显著地抑制制造业企业的污染排放,且这种抑制作用在不同的行业、地区和不同的所有制企业中具有异质性,其在高技术行业、东部及东北地区、外资企业和出口型企业中表现得更为明显。进一步的机制检验表明,这种抑制作用是通过提高生产率、促进能源消费结构转型的前端控制和提升污染处理能力的末端治理实现的。【结论】数字化转型有利于优化企业环境绩效,助力中国推进生态文明建设,因此要加快推动数字技术赋能制造业企业绿色转型,形成数字化和绿色化的良性循环,引领新的经济增长点。[Objective]Digital transformation provides an opportunity for manufacturing enterprises to save energy and reduce pollution emissions.Clarifying the impact of digital transformation on manufacturing enterprise pollution emissions and its mechanism provide important policy implications for high-quality economic development.[Methods]In this study,we used the fixed effect model,moderating effect model,and instrumental variable method to examine the impact of digital transformation on manufacturing enterprise pollution emissions and its mechanism based on the matching data of the China Industrial Enterprises Database,China Industrial Enterprises Pollution Emissions Database,and the World Input-Output Database.[Results](1)The empirical results show that digital transformation can significantly inhibit the pollution emissions of manufacturing enterprises,and this inhibitory effect has heterogeneity across different industries,regions,and types of firm ownership.Specifically,the impact is greater in high-tech industries,eastern and northeastern regions,foreign investment firms,and export-oriented firms.(2)Further mechanism test results show that this inhibitory effect is achieved by the front-end control to improve productivity and promote energy consumption structure transformation,and back-end governance to improve pollution treatment capacity.[Conclusion]Digital transformation is conducive to optimizing enterprise environmental performance and helping advance ecological civilization.It is necessary to promote digital technology to empower the green transformation of manufacturing enterprises,form a virtuous cycle of digitalization and greening,and lead the formation of new economic growth points.
