【摘要】 采用MAP-CGE模型,模拟了我国水泥行业实施低碳水泥标准对不同生产工艺产出、能耗及污染排放的影响,测算了对其边际减排成本和均衡价格的影响,分析了对不同污染物的协同减排效果。模拟结果表明:实施低碳水泥标准有利于水泥生产工艺的升级换代,并有助于水泥行业节能减排;在现有技术水平下,水泥行业在减排1t CO₂的同时将带来约1.17 kg的SO₂减排量和4.44 kg的NO_x减排量;实施低碳水泥标准对于水泥行业控制NO_x排放很有利;但水泥行业也需承担减排成本并导致其均衡价格的小幅上升。更多还原

【Abstract】 Based on the MAP-CGE model,this paper simulates the impacts on the output,energy consumption and pollutant emission of different cement production processes when implementing the low carbon cement standard in China,calculates the impacts on the marginal abatement cost and equilibrium price of cement industry,and analyzes the co-abatement effects of different pollutants.The results show that implementing the low carbon cement standard will be beneficial to promoting the upgrading of cement production process,and strengthening the energy conservation and emission reduction in the cement industry.When reducing every ton of CO₂ emission,if the existing technology keeps unchanged,the cement industry will reduce SO₂ emission by 1.17 kg and NO_x emission by 4.44 kg at the same time.Implementing low carbon cement standard can also promote NO_x abatement in the cement industry.However, the cement industry will bear the abatement costs,and their equilibrium price will increase to a small extent.更多还原
