我国工业碳排放量占全国总量的70%以上，实施工业碳排放配额交易对于实现我国国家碳减排目标具有重要意义。同时，碳排放配额在行业或企业之间的分配是第一步，也是关键的一步。为此，本文在2015年水平的基础上，采用主观、客观和线性组合加权方法构建了2020年中国工业39个行业碳排放配额分配综合指数，并采用投入导向的ZSG-DEA模型检验了2020年分配方案的效率。相对其他两项指标的作用较高。其次，主观、客观和线性组合赋权方法都可以用于碳排放配额的有效分配，而从效率角度来看，前两种方法的优势较小。三是六大重点工业行业2020年碳排放配额分别超过5亿吨，合计占行业总量的91.77%。最终，最终的碳排放配额分配方案体现了公平和效率原则，达到帕累托最优状态。
The carbon emission of China’s industry accounts for more than 70 % of the total in the nation, thus the implementation of carbon emission quota trading in industry is of great importance to realize China’s national carbon emission reduction targets. Meanwhile, the allocation of carbon emission quota among sectors or enterprises proves the first and critical step. For this reason, this paper constructs a comprehensive index combined with the subjective, objective and linear combination weighting methods to allocate carbon emission quotas among the 39 sectors of China’s industry in 2020 based on the level of 2015, and employs the input-oriented ZSG-DEA model to examine the efficiency of allocation solutions in 2020. The results indicate that, first, when carbon emission reduction capacity, responsibility and potential are considered for the comprehensive index of carbon emission quota allocation, the mitigation responsibility plays a relatively higher role than other two indicators. Second, all of the subjective, objective and linear combination weighting methods can be used for effective allocation of carbon emission quotas, and the former two methods have less advantage in light of efficiency. Third, six key industrial sectors are respectively allocated over 500 million tonnes of carbon emission quotas in 2020, which together account for 91.77 % of the total in the industry. Finally, the final carbon emission quota allocation solution reflects both the equity and efficiency principles and achieve the Pareto optimal state.
