文章探究了数字新质生产力推动碳减排的作用机制，并基于2011-2022年中国282个地级及以上城市面板数据，实证检验数字新质生产力推动碳减排的理论假说。研究结果表明：数字新质生产力的发展能显著减少碳排放。作用机制检验显示，绿色技术创新和产业结构升级是数字新质生产力推动碳减排的重要机制。区域差异性检验显示，东部地区数字新质生产力的发展显著降低了碳排放强度，而中西部地区数字新质生产力的发展对碳减排的作用未通过检验。空间效应检验显示，数字新质生产力对碳减排的影响存在显著的空间溢出效应，即数字新质生产力的发展不仅能降低本区域碳排放强度，也能有效促进邻近区域的碳减排。研究结论为探索数字新质生产力促进碳减排的路径提供了经验证据和决策参考。

This paper explores the mechanisms through which digital new quality productive forces promote carbon emission reduction,and empirically tests the theoretical hypothesis that digital new quality productive forces promote carbon emission reduction based on the panel data of 282 cities at and above the prefecture level from 2011 to 2022.The results show that the development of digital new quality productive forces can significantly reduce carbon emissions.Mechanism test shows that green technology innovation and industrial structure upgrading are key mechanisms through which digital new quality productive forces promote carbon emission reduction.Regional disparity test shows that the development of digital new quality productive forces in the eastern region significantly reduces carbon emission intensity,while the development of digital new quality productive forces in the central and western regions does not exert a significant effect on carbon emission reduction.Spatial effect test shows that the impact of digital new quality productive forces on carbon emission reduction exhibits a significant spatial spillover effect,that is,the development of digital new quality productive forces can not only reduce carbon emission intensity within a region,but also effectively promote carbon emission reduction in neighboring regions.The study provides empirical evidence and decision-making reference for exploring the pathways through which digital new quality productive forces promote carbon emission reduction.
