Study Blockchain-Based Supply Chain Finance System of the Construction Industrialization

Small and medium-sized enterprises (SMEs) in the construction industrialization supply chain are facing a huge financial gap, limited financing sources, and high costs. Blockchain technology is seen as the solution to the problems faced by SMEs in the construction industrialization supply chain as it reduces financing costs and improves efficiency. To explore the influencing factors on the behavior of each participant in construction industrialization supply chain finance, this study establishes a multi-agent model in accordance with the blockchain-based supply chain finance system of construction industrialization. This study first analyzes four subjects of the construction supply chain finance system: general contractors, financial institutions, logistics companies, and material suppliers, and the factors that influence the decision-making of construction supply chain finance subjects: policy support, competitive pressure, perceived benefits, and perceived costs, and system structure. It also designs decision rules based on prospect theory and simulates the model using Netlogo, and the results provide a basis for promoting the application of blockchain in supply chain finance and solving the financing problem of industrialization of construction.
