"双碳"目标下制造业碳减排的数 字技术实现路径研究OACHSSCDCSTPCD

Digital technology is a favorable tool for China to achieve the carbon peaking and carbon neutrality goals,and provides a new path choice for manufacturing industry to reduce carbon emission intensity.Based on China's provincial panel data from 2010 to 2021,this paper verifies whether digital technology can be an effective way to reduce carbon emissions in manufacturing and examines the intermediary effect of technological innovation and the regulatory role of green level.Results show that digital technology can signifi-cantly reduce the carbon emission intensity of the manufacturing industry and digital technology has the effect of carbon emission reduc-tion in the manufacturing industry.After a series of robustness tests,the results remain robust.The negative impact of digital technology on the carbon emission intensity of manufacturing industries in different regions is significantly different.The manufacturing carbon re-duction effects of digital technologies are even more pronounced in the central and western regions.Digital technology has a significant carbon reduction effect on capital-intensive manufacturing.The carbon emission reduction effect on labor-and technology-intensive manufacturing industry is not significant.Digital technology has a significant negative impact on carbon emissions in both high carbon and low carbon manufacturing industries.The carbon emission reduction effect of digital technology in manufacturing can be realized through the effect of technological innovation.The green level can positively adjust the carbon emission reduction effect of digital tech-nology in manufacturing,and the adjustment effect is more significant in the eastern,central and western regions.
