【Abstract】Modular integrated construction (MiC) becomes a promising solution to improve production efficiency in the construction industry. However, the off-site production and on-site installation processes of MiC pose challenges to collaboration efficiency among the multiple stakeholders involved, including subcontractors, contractors, and consumers. These challenges stem from information dispersion, which impedes effective collaboration and communication. Such problems can be solved by introducing a blockchain-based cyber-physical service platform, which can facilitate information sharing and collaboration across the supply chain. In this paper, we study the impacts of MiC and blockchain technology on construction supply chains and reveal several important insights. First, we find that there exists a first-mover advantage in the traditional construction supply chain, where subcontractors engage in a sequential game, and the subcontractor who produces first obtains more profit than the counterparts. Moreover, the contractor's ability to increase profits by reducing the unit cost of construction time is limited, but it can improve the effectiveness of the time gap due to early delivery. Second, we show that MiC should not be introduced if it significantly reduces collaboration efficiency in the supply chain. Interestingly, increasing the unit cost of construction for subcontractors can actually result in greater profits for all members of the supply chain. Regarding adopting blockchain technology, our findings suggest that supply chain members generally hold similar attitudes. Specifically, when the value of blockchain in improving collaboration efficiency is below a certain threshold, its adoption may not be beneficial, despite its potential to enable rapid production and early delivery.
