中文摘要：

为研究城市建设用地集约利用度与其碳排放效率之间的关系,针对省际建设用地,构建城市建设用地集约利用评价指标体系,计算中国大陆30 个省份的建设用地集约利用度;基于松弛测度的SBM 模型,测算各省份建设用地集约利用的碳排放综合效率、技术效率与规模效率.结果表明：（1） 城市建设用地集约利用程度与集约利用碳排放综合效率并不保持普遍一致;（2）建设用地集约利用度高的省份大多分布在东部地区;（3）区域建设用地集约利用碳排放技术效率不足是导致大多数省份综合效率偏低的主要原因,而规模效率不足对综合效率影响较小.

英文摘要：

In order to study the consistency relationship between intensity of construction land use and carbon emission efficiency, for inter-provincial construction land,an index system of evaluating urban construction land use intensity was built, and based on a slacks-based measure model, the total efficiency values, technical efficiency values, and scale efficiency values of carbon emission from urban construction land intensive use in 30 provinces were calculated. Consistency between urban construction land use intensity and its efficiency of carbon emissions does not exist widely in China. The provinces whose intensity values of construction land use are large are mainly lo-cated in eastern China. The main reason for the low total efficiency is the imperfect technical efficiency of carbon e-missions from urban construction land intensive use, and the imperfect scale efficiency have little effect on the low total efficiency. The above quantitative analysis is helpful to the new policies established to improve carbon emission efficiency of each province in the future.
