【摘要】：根据我国各省建筑业2005-2012年的相关数据,以建筑业从业人数、科技经费支出总额、技术装备率、建筑业总产值作为投入指标,以建筑业的CO2排放量、建筑业总能耗2个指标作为低碳行为的产出指标,构建基于投入产出分析的DEA(Data Envelopment Analysis)模型计算我国建筑业低碳行为下的静态效率,利用Malmquist指数分析我国建筑业低碳行为下的动态效率,并进行静态效率与动态效率的比较.结果表明,在2005-2012年期间我国建筑业低碳行为下的整体效率偏低,大部分区域的建筑业低碳效率与处于最优生产前沿面上的决策单元差距大,在技术效率及规模效率上都仍有较大的改进空间.通过静态效率与动态效率的比较分析不同区域建筑业低碳行为模式的差异,并提出了提高建筑业低碳效率的对策建议.
[Abstract]:According to the relevant data of the construction industry in China from 2005 to 2012, taking the number of people employed in the construction industry, the total expenditure on science and technology, the ratio of technical equipment and the gross output value of the construction industry as the input indicators, the CO2 emission of the construction industry is taken as the input As the output index of low-carbon behavior, the DEA (Data Envelopment Analysis) model based on input-output analysis is constructed to calculate the static efficiency of low-carbon behavior of Chinese construction industry. The dynamic efficiency under low carbon behavior of Chinese construction industry is analyzed by Malmquist index, and the static efficiency and dynamic efficiency are compared. The results show that during the period of 2005-2012, the overall efficiency of low-carbon construction industry in China is low, and there is a large gap between the low-carbon efficiency of construction industry in most regions and the decision-making units (DMUs) in the front of optimal production. There is still room for improvement in technical efficiency and scale efficiency. Through the comparison of static efficiency and dynamic efficiency, this paper analyzes the differences of low-carbon behavior patterns of construction industry in different regions, and puts forward some countermeasures to improve the low-carbon efficiency of construction industry.
