Regional Disparities and Convergence of ProvincialConstruction Waste in China

Construction and Demolition Waste（ C&DW） reduction management is crucial to the sustainable development of theconstruction industry. Based on the calculation of C&DW emissions in China from 2005 to 2018, the Theil index is used to calculatethe intra-regional disparities, inter-regional disparities, and overall Theil index of C&DW emissions in different regions. Theconvergence analysis of C&DW emissions in different regions is also conducted. The results show that the C&DW emissions areregionally 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 aresmall, with conditional β convergence across regions. The research results aim to explore the spatial difference of C&DW emissionsand provide a reference for the government to formulate regional differentiated C&DW reduction management policies.
