【摘要】 文章基于长江经济带11省(市)2011～2022年的统计数据，构建固定效应面板模型，检验新质生产力、产业结构升级对碳排放的影响。在此基础上，进一步构建中介效应模型，检验新质生产力对碳排放的影响机制。结果显示：新质生产力、产业结构升级能有效抑制长江经济带全流域碳排放量，在长江下游地区效果更加明显；在新质生产力抑制碳排放的过程中，产业结构升级发挥了部分中介作用。因此，应当全力促进新质生产力形成发展，全面赋能产业转型升级；有效推动产业结构优化和升级，全面促进经济绿色发展；努力提升全域全要素协同水平，全面构建绿色产业链群。更多还原

【Abstract】 Based on the statistical data from the 11 provinces(cities) of the Yangtze River Economic Belt from 2011 to 2022,this paper constructs a fixed effects model to examine the impact of new quality productivity and industrial structure upgrading on carbon emissions.Additionally, a mediation effect model is developed to explore the mechanism by which new quality productivity affects carbon emissions.The results indicate that new quality productivity and industrial structure upgrading can effectively suppress carbon emissions across the entire Yangtze River Economic Belt, with a more pronounced effect in the downstream regions.Furthermore, industrial structure upgrading plays a partial mediating role in the process by which new quality productivity suppresses carbon emissions.Therefore, it is imperative to fully promote the development of new quality productivity, empower industrial transformation and upgrading comprehensively, effectively drive the optimization and upgrading of industrial structures, and holistically foster green economic development.Efforts should be made to enhance the coordination of all elements across the entire region, constructing a comprehensive green industrial chain cluster.更多还原
