辽宁省建筑业碳排放与经济发展脱钩现象研究

Research on Decoupling between Carbon Emission of Construction Industry and Economic Development in Liaoning Province

建筑业作为辽宁省支柱产业,其节能减排潜力较大。通过能源消耗量和投入产出分析对辽宁省建筑业碳排放量进行了核算,利用Tapio脱钩模型和EKC曲线分析了辽宁省建筑业碳排放与经济发展之间的关系。结果表明:辽宁省建筑业碳排放总量在2010—2020年间呈几字形变化,于2015年到达拐点;脱钩弹性呈W形波动;EKC曲线总体呈上升趋势。最后结合2010—2020年辽宁省建筑业碳排放与经济发展脱钩情况提出了辽宁省建筑业的碳减排建议。

As a pillar industry in Liaoning Province,the construction industry has great potential for energy conservation and emission reduction.Through energy consumption and input-output analysis,the carbon emissions of Liaoning construction industry are calculated,and the relationship between carbon emissions of Liaoning construction industry and economic development is analyzed using Tapio elastic decoupling model and EKC curve.The results show that the total carbon emissions of the construction industry in Liaoning Province changed in Chinese character of“几”shape from 2010 to 2020,reaching an inflection point in 2015.The decoupling elasticity fluctuates in"W"shape and the EKC curve shows an overall upward trend.The decoupling level is closely related to carbon emissions,so carbon reduction suggestions are proposed from different aspects of direct and indirect carbon emissions.
