The extensive waste emissions and energy consumption in the construction industry has spurred calls for sustainable development reform. Identifying valuable development paradigms through evaluating the spatial-temporal environmental efficiency (EE) of the construction sector offers an effective avenue for practice guidance. However, a comprehensive and detailed global analysis of the construction sector's EE remains lacking. This study applies the super-slack-based measure (Super-SBM) model to assess EE of the construction sector across 112 countries from 2006 to 2016. The results reveal relatively low overall EE performance of global construction sector, with notable disparities among countries and improvements were observed in certain years. Singapore, Malta, and Paraguay emerge as top performers, while Moldova, Swaziland, and Iceland rank at the bottom. The findings highlight significantly better EE in European and coastal Asian countries compared to inland Asian and African nations. Using the Tobit model, we identify that industrial structure, trade dependency, international cooperation, energy intensity, and geographic factors significantly influence EE, with varying impacts across countries of different income levels. These findings provide a comprehensive overview of the global construction sector's environmental efficiency, emphasizing the urgent need for increased awareness and the adoption of sustainable practices. The study offers practical policy implications, advocating for targeted strategies to balance economic development with environmental protection.
建筑业大量的废弃物排放和能源消耗引发了对可持续发展改革的呼声。通过评估建筑业的时空环境效率（EE）来确定有价值的发展模式，为实践指导提供了一条有效途径。然而，目前仍缺乏对建筑业环境效率的全面而详细的全球分析。本研究应用基于超效率松弛测度（Super-SBM）模型，对2006年至2016年112个国家的建筑业环境效率进行评估。结果显示，全球建筑业的整体环境效率表现相对较低，各国之间存在显著差异，且在某些年份有所改善。新加坡、马耳他和巴拉圭表现最佳，而摩尔多瓦、斯威士兰和冰岛排名垫底。研究结果突出表明，与亚洲内陆和非洲国家相比，欧洲和亚洲沿海国家的环境效率明显更高。利用Tobit模型，我们发现产业结构、贸易依存度、国际合作、能源强度和地理因素对环境效率有显著影响，且在不同收入水平国家的影响各异。这些发现全面概述了全球建筑业的环境效率，强调了提高认识和采用可持续做法的迫切需要。该研究提供了切实可行的政策建议，倡导采取有针对性的战略来平衡经济发展与环境保护。
