Abstract：New-quality productivity serves as a crucial driver for promoting high-quality development and injecting new impetus into achieving the"dual carbon" goals and regional sustainable development.Based on panel data from 99 prefecture-level cities in the Yellow River Basin from 2012 to 2023,this study measures the level of new-quality productivity using the entropy method.Through constructing linear regression models,mediation effect models,moderation effect models,and threshold effect models,it empirically analyzes the impact mechanism of new-quality productivity on carbon emission efficiency in the Yellow River Basin.The research findings include:①New-quality productivity significantly promotes carbon emission efficiency;② The impact of new-quality productivity on carbon emission efficiency exhibits regional heterogeneity,showing a gradient enhancement from downstream to midstream and upstream cities;③ New-quality productivity enhances carbon emission efficiency by driving green technology innovation,and demonstrates a dual-threshold effect based on green technology innovation,with an increasing effect pattern;④ New-quality productivity plays a significant positive moderating role in the process influencing carbon emission efficiency.
