摘　　要：建筑废弃物减量化管理对建筑业可持续发展来说至关重要,在2005~2018年我国建筑废弃物排放测算基础上,用泰尔指数来计算建筑废弃物排放的区域内差异、区域间差异及总体泰尔指数,同时进行各地区建筑废弃物排放量的收敛性分析。结果表明:建筑废弃物产量区域性显著,总体表现出“东高西低”的特征,并且我国建筑废弃物排放量目前已进入较为稳定的发展状态,各地区和总体发展的差异出现变化的幅度较小,全国及各区域都存在着条件β收敛。研究成果旨在探究建筑废弃物产量的空间差异性,进而为政府制定区域差异化的建筑废弃物减量化管理政策提供参考。Construction and Demolition Waste(C&DW)reduction management is crucial to the sustainable development of the construction industry.Based on the calculation of C&DW emissions in China from 2005 to 2018,the Theil index is used to calculate the intra-regional disparities,inter-regional disparities,and overall Theil index of C&DW emissions in different regions.The convergence analysis of C&DW emissions in different regions is also conducted.The results show that the C&DW emissions are regionally significant,showing the overall characteristics of"the C&DW emissions in the east is higher than the west".Moreover,the C&DW emissions in China are in a relatively stable state of development,difference in regional and overall development are small,with conditionalβconvergence across regions.The research results aim to explore the spatial difference of C&DW emissions and provide a reference for the government to formulate regional differentiated C&DW reduction management policies.
