Abstract—Industrialized construction (IC) is a method with better productivity, quality, safety, and sustainability, which has attracted widespread attention from the global construction industry. Previous studies have mostly focused on prefabricated construction (PC), neglecting discussions on on-site industrialized construction (OIC). In concrete buildings, the theoretical comparison between the two needs to be evolved and incorporated with a global view and understanding. Therefore, this study constructed a theoretical comparative framework between PC and OIC, systematically sorting out their concepts, characteristics, goals, construction logic, and ecological relationships. Finally, based on this framework, this study proposes recommendations for selecting IC technology paths from aspects such as building height, structural construction, component properties, and enterprise level. The framework between PC and OIC emphasized in this paper has the potential to supplement the theoretical system of IC and provide guidance for the diversified development of global construction industrialization.
