The construction industry is a pillar industry of China's national economy but its problems of high energy consumption, high pollution, and low energy efficiency are increasingly prominent. The study on the energy efficiency of the construction industry is of great significance for improving development quality and achieving the goal of energy saving and emission reduction. In this paper, a three-stage undesirable SBM-DEA model was employed to measure the energy efficiency in the construction industry during 2005-2016. The CO directly emitted by the construction industry and indirectly emitted in the production of building materials were used as the undesirable output and the three-stage framework was employed to analyze and eliminate the influence of external environment. The empirical results showed that low efficiency of management in the construction industry is an important factor leading to the low level of energy efficiency in China's construction industry. For the energy efficiency value before and after adjustment, the "high-high" provinces have made full use of the superior external environment by their high management level, while the "high-low" provinces need to fully realize the potential in promoting energy efficiency of its external environment by improving its own management of the construction industry. On the contrary, the "low-high" provinces need to improve the external environment to ease its restrictions on the level of management in the construction industry. Environmental factors and management level should be considered simultaneously for different provinces to improve energy efficiency of the construction industry.
建筑业是中国国民经济的支柱产业，但高能耗、高污染、低能效的问题日益突出。研究建筑业的能效对于提高发展质量、实现节能减排目标具有重要意义。本文采用三阶段非期望 SBM-DEA 模型，测算了 2005-2016 年中国建筑业的能源效率。将建筑业直接排放的 CO2 和建筑材料生产过程中间接排放的 CO2 作为非期望产出，采用三阶段框架分析并消除外部环境的影响。实证结果表明，建筑业管理效率低下是导致中国建筑业能源效率水平较低的重要因素。对于调整前后的能源效率值，“高高”省份利用其较高的管理水平充分利用了优越的外部环境，而“高低”省份则需要通过提高建筑业管理水平，充分挖掘外部环境促进能源效率的潜力。相反，“低高”省份则需要改善外部环境，缓解其对建筑业管理水平的限制。对于不同的省份，需要同时考虑环境因素和管理水平，以提高建筑业的能源效率。
