【摘要】:针对传统DEA模型缺乏客观评价标准的问题,在采用三阶段DEA模型剔除环境因素和随机误差对建筑业碳排放投入指标的影响的基础上,以2005年建筑业碳排放强度降低45%的减排目标为样本单元,构建建筑业碳排放效率评价的广义DEA模型。以2003—2012年建筑业为实证,结果表明:我国建筑业碳排放效率逐年提升;建筑业碳排放技术效率与地区经济水平显著正相关,建筑业碳排放累计冗余与地区经济水平显著负相关;投入指标冗余率均呈现逐年递减趋势,但建筑业碳排放与机械设备累计冗余依然较为严重,建筑业减排潜力较大;建筑业资本存量冗余受宏观经济政策影响较大。研究成果可为区域化、差异化减排提供决策依据和理论指导。
[Abstract]:In view of the lack of objective evaluation criteria in traditional DEA model, the three-stage DEA model is adopted to eliminate environmental factors and random errors on the basis of the impact of environmental factors and random errors on the carbon emission input index of construction industry. Taking the target of reducing carbon emission intensity of construction industry by 45% in 2005 as the sample unit, the generalized DEA model of carbon emission efficiency evaluation of construction industry is constructed. The results show that the carbon emission efficiency of construction industry in China is increasing year by year. The technical efficiency of carbon emission in construction industry is significantly positively correlated with the regional economic level, the cumulative redundancy of carbon emissions in construction industry is negatively correlated with the regional economic level, and the redundancy rate of input indicators is decreasing year by year. However, the carbon emissions and the accumulated redundancy of machinery and equipment in the construction industry are still serious, the potential of emission reduction in the construction industry is great, the redundancy of the capital stock in the construction industry is greatly affected by macroeconomic policies, and the research results can be regionalized. Differential emission reduction provides decision-making basis and theoretical guidance.
