[Impact Effect and Action Mechanism of New Quality Productivity on the Pollution and Carbon Emission Reduction].

Exploring the impacts of new quality productivity on pollution and carbon emission reduction has important theoretical guiding significance for accelerating China's green and low-carbon transformation. Using panel data of 30 provinces in China from 2010 to 2022 as a research sample and based on the calculation of new quality productivity， environmental pollution emissions， and carbon emissions in each province through the years， the concrete impacts of new quality productivity on pollution and carbon emission reduction and their action mechanism， regional heterogeneity， and spatial spillover effect were investigated. Relevant policy recommendations pertaining to new quality productivity empowering pollution and carbon emission reductions were proposed. The study produced several notable results： ① From 2010 to 2022， China's new quality productivity showed a steady growth trend. The index of new labor materials grew the fastest， followed by the index of new workers； the index of new labor objects grew the slowest. The development difference of new quality productivity in different regions showed an increasing trend through time， and the inter-regional difference was the main source of the spatial difference of new quality productivity. ② From 2010 to 2022， environmental pollution emissions and carbon emissions in the country and the four regions showed a clear increasing trend， while the total carbon emission and carbon emission intensity showed a scissor-like difference pattern of change. ③ New quality productivity played a significant role in promoting the reduction of pollution and carbon emissions through the transformation and upgrading of industrial structure and the optimal allocation of resources. It played a positive role in reducing emissions of pollution and carbon in the eastern and western regions， but in the central and northeast regions， the impact was not satisfactory. The diffusion and interaction of new quality productivity across different regions had significant and positive spatial spillover effects， thereby promoting pollution and carbon emission reductions of the whole economy effectively.
