Sustainable development of the construction industry requires balancing economic growth and resulting environmental impacts. The aggregate embodied CO2 intensity (CI), defined as ratio emissions per value added, has been studied in previous research to evaluate environment performance mitigation policies from a final demand perspective. However, there is relative lack studies analysing CI perspective border-crossing frequency (BCF), number national border crossings traded products. This paper first analyses import products at each BCF under multi-regional input–output framework decomposes change into value-added distribution factor efficiency conditions BCF. results indicate that CIs industries experienced declines 2000 2014. appeared have an inhibitory effect only on prompted higher-order BCFs. had significant promoting decline but this promotion became weaker with increase level reduction changes was smaller than factor, indicating decrease largely determined by improvement Driving force analysis can effectively help adjusting structure order control
