Abstract: Solving the resource and environmental constraints faced by China benefits from studies on the decoupling relationship between the power industry’s CO2 emissions and economic development. This study provides new ideas for economic development by measuring the decoupling index of CO2 emissions within the power industry from 1985 to 2017 based on the Tapio decoupling model. Next, this study determines the key influencing factors of the decoupling index in the long- and short-term based on the autoregressive distributed lag model. The results show that: (1) In the past 30 years, the relationship between CO2 emissions and economic development has exhibited synchronization within the power industry; the base for the decoupling state is expansive negative decoupling and weak decoupling, and the strong decoupling state has existed for only five years. (2) The estimation results for the long-term effect indicate that coal-fired power generation efficiency and terminal energy intensity can effectively reduce the decoupling index with a coefficient of 3.0422 and 2.4822, respectively. (3) The estimation results for the short-term effect imply that decreasing terminal energy intensity reduces the decoupling index the most followed by energy consumption, and the two show coefficients of 9.5986 and 2.6404, respectively. Based on this conclusion, the study provides some recommendations for policy design, collaborative emissions reduction, and low-carbon energy construction in China’s power industry.
