On the basis of constructing an evaluation index system for energy consumption and green development level, the entropy method, coupling coordination degree model, Dagum Gini coefficient and its decomposition were used to calculate the coupling coordination level of energy consumption and green development in 30 provinces(due to the lack of data, the statistical data mentioned here do not include the Tibet Autonomous Region, the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan Province) of China from 2006 to 2021, and the regional differences in coupling coordination level among different regions were analyzed in depth. Research shows that the overall level of coupling and coordination between energy consumption and green development in China is on the rise, but the western region leads in energy consumption, while the eastern region leads in green development.The coupling coordination level between energy consumption and green development shows an increasing trend, with the overall level shifting from low coordination to moderate coordination, presenting a situation of “high in the east and low in the middle and west”. The overall difference in the coupling coordination between energy consumption and green development in the four major regions of East, Central, West and Northeast China is gradually narrowing, and the main source of the difference is regional differences. Reference is provided for promoting the deep integration of energy consumption and green development, and achieving the “dual carbon” goal.
