Abstract：The carbon emissions of the construction sector in the Yangtze River Delta region were calculated using the carbon emission coefficient method in this paper. The spatial variations, evolutionary characteristics, and driving factors of carbon emissions across 26 cities in the Yangtze River Delta were analyzed using the slope index, Theil index, and Logarithmic Mean Divisia Index (LMDI). The results indicated that between 2004 and 2020, the carbon emissions from the construction industry in the Yangtze River Delta were first increased and then exhibited a wave-like fluctuation, overall presenting a high-in-the-east and low-in-the-west spatial pattern. The overall disparity in carbon emissions within the construction sector of the Yangtze River Delta was diminished, first showing a wave-like increase and then a gradual decline. Notably, within the Yangtze River Delta region, the intra-provincial discrepancies contributed more to the overall variance than the inter-provincial discrepancies. Among the driving factors, the effects of economic development and housing construction area promoted the increase in carbon emissions, while factors such as population density, energy consumption intensity, and energy structure intensity played a suppressing role.
