“…At present, many scholars have conducted research on carbon emission, including the measurement and evaluation , dynamic change (Cheng et al, 2018b), influencing factors and effects analysis (Xu et al, 2021;Zhang H et al, 2021) of carbon emission efficiency. Scholars think that policy and supervision (Calvo et al, 2021;, technological innovation (Gouveia et al, 2021;He et al, 2021;Wu H et al, 2021;Wyse et al, 2021;Xie et al, 2021), human capital (Song et al, 2020), industrial structure (Cheng et al, 2018a;Wu L et al, 2021) and urbanization (Sun and Huang, 2020;Wang F et al, 2021) will affect carbon emission efficiency. and Meng et al (2016) used DEA model to measure the carbon emission efficiency of 42 thermal power plants and 30 provinces in China from the micro and macro levels respectively, and found that there was regional imbalance in China's carbon emission efficiency.…”
