Green and low-carbon development of construction industry is one of the important ways to achieve the "dual carbon" goal in China. This study first measured the carbon emissions of the construction industry in 30 provinces in China, and then used the Dagum Gini coefficient and its decomposition method to explore the regional differences and sources of carbon emissions of the construction industry in China. The results show that the carbon emissions of construction industry in China generally show an upward trend, and there are significant differences in carbon emissions of construction industry among provinces, and the main source of regional differences is inter-regional differences. However, the contribution rate of inter-regional differences showed a significant downward trend, while the contribution rate of hyperbolic density increased day by day, and the contribution rate of intra-regional differences increased slightly. The results of this study will provide a reference for China to formulate more reasonable carbon emission reduction targets and differentiation strategies for the construction industry.
