Abstract: New quality productivity are advanced productivity that break away from traditional growth paths and are more in line with new development concepts, it continuously decouple from resource consumption in the process of development, providing new momentum for the green and low-carbon economic and social development. Different from the perspectives of existing research on measuring the development level and impact effects of new quality productivity,it focuses on exploring the decoupling effect of resource consumption of new quality productivity based on the measurement of their level. Based on panel data from 30 provincial-level administrative regions in China from 2011 to 2022, the entropy weight TOPSIS method is used to measure the development level of new quality productivity, and the Tapio elastic decoupling model is further used The LMDI decomposition model calculates the decoupling level and driving factors between new quality productivity and resource consumption. The results showed that during the research period, the development level of new quality productivity in the national and provincial-level administrative regions showed a steady upward trend during the T1-T4 period, and showed a differentiated pattern of eastern>central>northeast>western regions. Decoupling analysis confirms that there are significant differences in the decoupling status between new quality productivity and resource consumption among provinces, with Beijing, Tianjin, Shanghai, Jiangsu, Zhejiang, and Guangdong all reaching strong decoupling status. Guizhou, Yunnan, Shaanxi, Qinghai, Ningxia and Xinjiang are in a growth linkage state. The remaining 18 provinces, cities, and autonomous regions are in a weak decoupling state. The decomposition of decoupling driving factors reveals that digital economy development, green technology innovation, strategic emerging industry agglomeration, and environmental regulation are the four major driving factors for the decoupling of new quality productivity and resource consumption, and environmental regulation plays a major driving role in the decoupling process. Based on the above conclusions, suggestions are proposed to develop new quality productivity according to local conditions, draw a blueprint for green technology innovation and development, and flexibly apply environmental regulation combinations, so as to provide useful references for accelerating the development of new quality productivity and promote resource consumption decoupling.
