Abstract: The construction industry plays a vital role in global economic development and is also an important industrial sector affecting global energy consumption. Energy conservation is an important guarantee for global sustainable development. Based on the perspective of embodied energy intensity of the global construction industry, this paper analyzes the reasons behind its high energy consumption. This paper uses a multi-regional structural path analysis model to explore the path of embodied energy intensity (EEI) in the global construction industry. The results show that the 2nd layer is the main path for the EEI in the global construction industry. In contrast, the higher layer plays an increasingly critical role in the EEI of the global construction industry. Its contribution increased by 49.27% during the study period. The construction material supply is the main source in the 2nd layer, and the coke and petroleum product manufacturing and power and gas supply are the main sources in the higher layer. Among the factors driving the inter-temporal change of EEI in the global construction industry, the sector energy intensity effect has a promoting effect on the decline of the EEI in all layers, while the final demand effect and input-output structure effect inhibit the EEI decline.
