效率視角下中國2030年二氧化碳排放峰值目標(biāo)的省區(qū)分解——基于零和收益DEA模型的研究
[Abstract]:Achieving a peak carbon dioxide emissions in 2030 is not only China's international commitment to global climate negotiations, but also an inevitable choice for China to achieve structural transformation of its economy. A reasonable regional decomposition of carbon dioxide emission peak is a necessary prerequisite for China to achieve a peak carbon dioxide emission peak. In this paper, the initial provincial and regional decomposition of China's 2030 peak carbon dioxide emission is carried out, and the efficiency of the initial provincial and regional decomposition scheme is evaluated by using DEA-BCC model. On this basis, the zero-sum income DEA model is used to obtain an effective decomposition scheme for all provinces and regions to achieve peak carbon dioxide emissions in China. The results show that: (1) the efficiency of the initial decomposition scheme of most provinces and autonomous regions is low, and only two provinces and regions have the efficiency of DEA. Moreover, the allocation efficiency of the larger proportion of carbon dioxide emission quota is relatively small. (2) through the optimization of zero-sum DEA model, the overall efficiency of the decomposition scheme of the province and region is promoted to the effective boundary. Carbon dioxide emission quotas have been transferred from less efficient less developed regions to more efficient developed regions, and both more developed and less developed regions have been allocated less carbon dioxide emission quotas, In the end, the regions with more carbon dioxide emission rights are the provinces with serious carbon dioxide emissions but great emission reduction potential. Finally, according to the conclusion of this study, the paper puts forward specific policy recommendations on the decomposition of carbon emissions in provinces and regions.
