| Abstract: | Due to the aggravation of environmental pollution and greenhouse effect, Chinese governments at all levels have taken a series of measures to conserve energy and reduce emissions. Scholars have proposed many methods to analyze the performance of energy conservation and emission reduction. Considering regional heterogeneity, the most used method is meta-frontier data envelopment analysis. However, an infeasible combination of inputs and outputs is observed in the traditional meta-frontier DEA approach. To solve this problem, a feasible target meta-frontier DEA model is proposed in this study. The analysis on ECER in Chinese regions has verified the validity of the proposed model, and some valuable research conclusions have been obtained. First, due to the adoption of the reachable common frontier, the performance of each province observed in this study is higher than the performance under the traditional meta-frontier. Second, regardless of the meta-frontier performance or the technology gap ratio value, the eastern region performs the best, whereas the central and western regions perform the worst. Third, the inefficiency of central and northeastern regions is mainly caused by insufficient technology, whereas that of the western region is caused by poor management and insufficient technology. Finally, this study provides suggestions for improving China's regional ECER performance on the basis of the conclusions. [ABSTRACT FROM AUTHOR] |
