Abstract This study applied the Logarithmic Mean Divisia Index (LMDI) model to analyze changes in carbon dioxide emissions by Chinese power industry from 2003 to 2017. Besides, the Tapio decoupling analysis model is applied to explore the decoupling states between power industry carbon dioxide emissions and the corresponding influence factors. Several conclusions were obtained: (1) the power industry carbon dioxide emissions only displayed a slight downward trend during 2011–2012, 2013– 2014, and 2014–2015; (2) the factors promoting the growth in power industry carbon dioxide emissions are energy consumption structure effect and total power generation effect. Power generation structural effect and fossil energy conversion efficiency effect inhibit the power industry carbon dioxide emissions from increasing, but they were far from offsetting the positive contribution value brought by total power generation effect; (3) changes in carbon dioxide emissions by the power industry were not sensitive to the change of fossil energy conversion efficiency and power production structure but were sensitive to the change of total power generation; (4) the contributions of technical effect were higher than those of structural effect on the decoupling index between impact factors and power industry carbon dioxide emissions.

Introduction When power industry plays a leading and important role in the development of the national economy, it also brings a tremendous amount of carbon dioxide emissions, which are detrimental to environment carbon emissions. National economy development cannot maintain without the continuous provision of electricity for all industries and households. In China, the electricity consumption increased from 145.84 million Responsible Editor: Eyup Dogan * Guijing Chen [email protected] 1

tons of standard coal equivalent (Mtce) in 2003 to 663.52 Mtce in 2018 (China National Bureau of Statistics 2018). However, to guarantee such huge requirements on electricity, power industry needs to consume tons of energy and resources, which are the source of carbon dioxide emissions. With the fast progress of society and economy, industrial and residential electricity consumption is increasing day by day. Such increase in electricity consumption contributes to the growth of carbon
