Abstract: Using comprehensive industrial linkage analysis and quantitative structural decomposition analysis based on the multi-regional input-output model, this study systematically explores the intrinsic characteristics and driving determinants of, and variations in the consumption-based embodied carbon emissions (CBEC) significantly generated by the urban construction industry. The results show that: (1) Gross fixed capital formation and consumption by urban residents lead to obvious CBEC heterogeneity; (2) Construction industry’s gross fixed capital formation drives the CBEC of the Production and Supply of Electric Power and Hot Water, Smelting and Pressing of Metals, and Nonmetal Mineral Products; (3) The CBEC shows significant dynamic spatiotemporal changes; (4) The emissions intensity effect and input-output structure effect are considered to be the key impetuses for increasing and decreasing the CBEC, respectively. Our study enhances understanding of spatiotemporal characteristics and multi-factor mechanisms of carbon emissions in construction, aids carbon peak and neutrality efforts, and guides urban environmental and energy planning.
