Evolution Game Analysis of Supply Chain Synergy Benefits of Prefabricated Building Projects

Aiming at the current situation of insufficient research on the synergistic benefits of the prefabricated building supply chain, this study utilizes the evolutionary game theory to construct an evolutionary game model among the three participating subjects of “government–construction unit–prefabricated component manufacturer”. Our study uses dynamic replication equations to derive the equilibrium point of the game, draw the evolutionary path of the prefabricated building, and analyze the strategic behaviors of each subject’s game evolution law. Providing lessons for the strategy selection of each subject while improving the level of assembly, building supply chain synergy is taken as the main goal of this study. The results of the study show that in the initial stage of assembly building supply chain collaboration, the government’s guidance and support can rapidly increase the willingness of all parties to collaborate; the reasonable distribution of the benefits of collaborative incentives is a prerequisite for the sustainable and stable development of the supply chain collaboration, and the construction unit, as the core body of the supply chain, should be given more attention in this link. The participants in the supply chain can effectively improve the level of supply chain synergy and decision-making efficiency by applying the model in this study.
