Past research has examined the relationship between power energy efficiency and CO2 on a single level, but there has been little focus on other damaging pollutants such as PM2.5 or their treatment. Further, most past efficiency analyses have been static and have lacked dynamic time considerations. Therefore, to go some way to filling these research gaps, this study proposed an undesirable directional distance function (DDF) dynamic data envelopment analysis (DEA) to explore power production and environmental efficiency in 31 Chinese provinces/municipalities/autonomous regions from 2008 to 2017, from which it was found that Beijing, Guangdong, Hunan, Jilin, Jiangsu, Shanghai, Tianjin and Tibet all had efficiencies of 1, but the power industry efficiencies in the western provinces/municipalities/autonomous regions—Inner Mongolia, Gansu, Ningxia and Xinjiang— needed significant improvements; Most areas, especially Liaoning, Inner Mongolia, Fujian, Shandong, and Tibet, needed environmental treatment efficiency improvements; and the need for carbon dioxide emissions improvements in most provinces/municipalities/autonomous regions was relatively stable, but there were large differences in the need for PM2.5 improvements. |
