Atmospheric environment governance requires necessary cost input. Only by accurately calculating regional atmospheric environment governance cost and scientifically allocating it within a region can the operability and realization of the coordinated governance of the regional environment be ensured. Firstly, based on the consideration of avoiding the technological regression of decision-making units, this paper constructs a sequential SBM-DEA efficiency measurement model and solves the shadow prices of various atmospheric environmental factors, that is, their unit governance costs. Secondly, combined with the emission reduction potential, the total regional atmospheric environment governance cost can be calculated. Thirdly, the Shapley value method is modified to calculate the contribution rate of each province to the whole region, and the equitable allocation scheme of the atmospheric environment governance cost is obtained. Finally, with the goal that the allocation scheme based on the fixed cost allocation DEA (FCA-DEA) model converges with the fair allocation scheme based on the modified Shapley value, a modified FCA-DEA model is constructed to achieve the efficiency and fairness of the allocation of atmospheric environment governance cost. The calculation and allocation of the atmospheric environmental governance cost in the Yangtze River Economic Belt in 2025 verify the feasibility and advantages of the models proposed in this paper.
大气环境治理需要必要的成本投入。只有准确计算区域大气环境治理成本，并在区域内科学配置，才能保证区域环境协同治理的可操作性和实现。首先，基于避免决策单元技术回归的考虑，本文构建了一个序贯 SBM-DEA 效率测度模型，并求解了各大气环境因素的影子价格，即其单位治理成本。其次，结合减排潜力，计算出区域大气环境治理总成本。再次，修正 Shapley 值法计算各省份对全区域的贡献度，得到大气环境治理成本的公平分配方案。最后，以基于固定成本分配 DEA（FCA-DEA）模型的分配方案收敛于基于修正 Shapley 值的公平分配方案为目标，构建修正 FCA-DEA 模型，实现大气环境治理成本分配的效率和公平。2025 年长江经济带大气环境治理成本的计算和分配验证了本文所提出模型的可行性和优势。
