Green cost performance measure of China's thermal power industry: evidence from Chinese 30 provinces

As the concentration of carbon dioxide within the environment increases, the dwelling environment of people is significantly influenced. As an industry with excessive carbon emissions in China, thermal energy companies are the major areas where China should lower carbon emissions. This research first adopts a New-Cost model to survey the energy performance of thermal-electricity field in four foremost regions of China from 2013 to 2017. Due to the variations in technology of thermal power generation among four regions, The technology gap ratio analysis is applied to estimate the gap between the group frontier and meta-frontier technology. The estimated results display that the eastern region is better in terms of efficiency than the other three regions, also there is a great technological gap in the northeastern region. On the premise of the research conclusions, further improving the performance of Chinese thermal power organizations underneath carbon emission constraints in the future is proposed in this study. It is significantly profitable for several companies to optimize their own short comings.
