摘　　要：推动公共建筑节能降碳对实现“双碳”目标意义重大。目前,碳交易市场对公共建筑的吸引力度不大、交易量较小,对公共建筑减排的促进作用有限。从碳排放权价值角度,对商业公共建筑的边际减排成本进行研究。聚焦于具有经营性质的批发和零售、住宿和餐饮类商业公共建筑,构建了以二氧化碳排放为非期望产出的影子价格模型,并进行参数化求解。实证结果表明:2013—2022年商业公共建筑边际减排成本约为0.48万元/吨~1.09万元/吨,且减排成本在波动中上升,减排的经济压力增大。边际减排成本远高于现有碳市场成交价格,给商业公共建筑主体积极参与碳交易构成了较大阻碍。对各地区减排成本与能源效率联合分析结果表明,东部、中部、西部地区存在差异。相关部门应结合各地区影子价格和市场价格,制定合理的价格及监管政策,鼓励商业公共建筑主体积极参与碳交易,推动建筑领域节能减排。Promoting energy conservation and carbon reduction in public buildings is of great significance for achieving the“dual carbon”goals.At present,the carbon trading market has limited attraction and small trading volume for public buildings,and its role in promoting emissions reduction in public buildings is limited.This pa‐per studies the marginal emission reduction cost of commercial public buildings from the perspective of carbon emission right value.Focusing on the commercial public buildings of wholesale and retail,accommodation and catering with the nature of business,this paper constructs a shadow price model with carbon dioxide emission as the non-expected output,and performs parametric solutions.The empirical results show that the marginal emis‐sion reduction cost of commercial public buildings from 2013 to 2022 was about 4800 to 10900 yuan per ton,and the emission reduction cost was rising in the fluctuation,leading to increased economic pressure on emission re‐duction.The marginal cost of emission reduction was much higher than the existing carbon market transaction price,which posed a significant obstacle for commercial public building entities to actively participate in carbon trading.The joint analysis of emission reduction costs and energy efficiency in different regions showed that there were differences in the eastern,central,and western economic regions.Relevant departments should combine shadow prices and market prices in various regions,formulate reasonable pricing and regulatory policies encourage commercial public building entities to actively participate in carbon trading,so as to promote energy conservation and emission reduction in the construction industry.
