Abstract
Research on the decoupling evolution of carbon emissions from economic efficiency (EE) is essential for advancing decarbonization in the construction sector. While previous studies have extensively investigated the decoupling of total carbon emissions (TC), per capita carbon emissions (PC), and carbon intensity (CI) in isolation, they often neglect comprehensive analysis. This gap hinders a nuanced understanding of the decoupling status within the construction sector, as each parameter—TC, PC, and CI—provides unique insights. Therefore, this work contributes to this gap by developing a comparative perspective on the decoupling trajectories for TC, PC, and CI. This holistic comparison will illuminate the dynamics and distinct roles of these parameters in the decoupling process from EE, providing rounded insights into the sector’s decoupling status by considering cumulative emissions, workforce practices and emission efficiency. Using the Tapio decoupling model and Generalized method of moments (GMM) estimation, the empirical analysis examined the decoupling status of the construction sector across 30 Chinese provinces from 2012 to 2021, yielding the following key findings. Firstly, the decoupling performances for TC, PC, and CI indicate general improvements, with an exception of 2019. Spatially, the decoupling for TC, PC, and CI exhibits similarities, with strong decoupling (SD) primarily occurring in eastern provinces while strong negative decoupling (SND) concentrated in western provinces. Secondly, CI is likely to be the leading parameter to achieve SD, relative to TC and PC. Furthermore, the GMM estimation reveals inverted N-shaped patterns in the decoupling of TC, PC and CI. Lastly, this study provides policy recommendations to address the unique challenges faced by regions. Theoretically, this research enriches the discourse on carbon emissions in the construction sector and contributes to the field of economic geography. Practically, it aids policymakers in setting achievable carbon reduction targets and developing effective action plans.
