我国建筑业碳排放演变特征及LMDI影响因素分解

摘要

在测算各省市(区)2005~2012年建筑业碳排放的基础上,利用Kernel密度估计法分析我国建筑业碳排放的演变特征,同时构建一个基于建设规模、能源结构、能源强度、单位产值的建筑业碳排放恒等式,运用LMDI分解技术对我国建筑业2005~2012年的碳排放进行因素分解.在此基础上,提出建筑业低碳发展的相应对策建议.%On the basis of calculating the construction industry's carbon emissions of 30 provinces and cities in 2005 to 2012,the paper uses Kernel density estimation method to analyze the dynamic evolution of construction industry's carbon emissions,and establishes a carbon emission identity basedon construction scale,energy structure,energy intensity and per unit output value. Then,applies LMDI model to decompose the factors of construction industry's carbon emission from 2005 to 2012. On the basis,proposes the contermeasures and suggestions for low carbon emission development in construction industry.
