【 摘 要 】

In this paper, the DEA model and factor analysis method are used to construct the energy efficiency evaluation model and the carbon emission factor decomposition model of the construction industry, so that it could analyse the energy efficiency evaluation of the construction industry in each province of China and give the emission reduction strategy. According to the data from China's construction industry statistical yearbook from 2007 to 2015, the paper analyses the energy efficiency of the construction industry, the main influencing factors of carbon emissions, the non-effective province redundancy and the redundancy rate of energy efficiency, and propose improvement measures for energy efficiency in the construction industry in 30 provinces of China. The results show that there are only 7 provinces with effective energy efficiency in the construction industry; 6 provinces with only technically effective; among other provinces, only Jiangxi Province has increased returns to scale, and the other 16 provinces are declining in scale.
