绿色发展已成为制造业高质量发展的必然要求,而数字经济正逐渐成为推动制造业绿色发展的重要动力。基于2013~2023年中国省级面板数据,运用双固定效应模型、中介效应模型和调节效应模型,探究数字经济对制造业绿色发展的影响和作用机制。研究表明:数字经济能够显著推动制造业绿色发展水平,并通过推动产业结构升级提升制造业绿色发展水平;绿色技术创新在数字经济和制造业绿色发展的关系中起正向调节作用;数字经济对制造业绿色发展的影响存在不同区域、不同数字经济水平和不同收入水平的差异性。探究数字经济对制造业绿色发展的影响有利于深化认识制造业绿色发展的影响因素,为进一步推动制造业绿色发展具有重要的理论意义。Green development has become an inevitable requirement for the high-quality development of the manufacturing industry, and the digital economy is gradually becoming an important driving force for the green development of the manufacturing industry. Based on China’s provincial panel data from 2013 to 2023, the dual fixed effect model, intermediary effect model and moderating effect model were used to explore the impact and mechanism of digital economy on the green development of manufacturing industry. The results show that the digital economy can significantly promote the green development level of the manufacturing industry, and improve the green development level of the manufacturing industry through industrial structure upgrading. Green technology innovation plays a positive regulating role in the relationship between digital economy and green development of manufacturing industry. The impact of digital economy on the green development of manufacturing industry varies from region to region, to different digital economy levels and to different income levels. Exploring the impact of digital economy on the green development of manufacturing industry is conducive to deepening t
