Research on the coupling and coordinated development of new quality productivity and carbon emission efficiency and influencing factors

Abstract

It is of great significance for China to study the internal relationship and coordination level between new productivity and carbon emission efficiency. Based on the panel data of 30 provinces and cities in China from 2014 to 2022, this paper measures the level of new productivity, carbon emission efficiency and their coupling coordination, and studies the main factors with the help of xgboost and shap model. The results show that the coupling coordination level of China is on the rise, and the coupling coordination level of the eastern region is much higher than that of the central and western regions; Per capita disposable GDP. The first three factors are promotion and the last two are inhibition. With the increase of disposable income, urban employment has changed from negative adjustment to positive adjustment, and the length of optical cable has a positive adjustment effect on GDP.
