Differential Game Model of Information Sharing among Supply Chain Finance Based on Blockchain Technology

Abstract

In the development of traditional supply-chain finance, the information asymmetry of all parties in the supply chain has become the primary problem hindering its development. Blockchain technology is an effective method to solve the problem of information silos. Based on differential game theory, this paper constructs a game model of supply-chain financial information-sharing behavior based on blockchain technology. Three scenarios of independent decision, the cost-subsidy mechanism of financial institutions, and dealers and collaborative decisions are studied, and the theoretical model is verified through a simulation algorithm. The results show that information sharing in supply-chain finance based on blockchain technology is much higher than that of traditional supply-chain finance, and the use of blockchain technology can promote more sustainable development of supply chains. Blockchain technology can effectively solve the information-silo effect, and the information sharing cost-subsidy mechanism can effectively relieve the cost pressure of information sharing and optimize the supply-chain structure. In addition, the amount of information and benefits shared among the three parties of supply-chain finance based on blockchain technology and the overall benefits show an increasing and stabilized trend over time. This study provides a reference for supply-chain finance members to reasonably choose the optimal strategic behavior.

SEIR-diffusion modeling and stability analysis of supply chain finance based on blockchain technology

“…Blockchain technology solves the problem pertaining to opaque information by building a data sharing platform. Xu et al constructed a game model of supply chain financial information sharing behavior based on blockchain technology with the differential game theory, and verified that blockchain technology can effectively alleviate the information island effect [ 34 ]. Chod et al validated the role of information transparency in enhancing the ability of firms to obtain favorable financing terms that exhibits low information transfer costs [ 35 ].…”

“…Information sharing increases transparency among organizations in the supply chain [33]. Avoiding information silos can effectively solve the problem of information asymmetry hindering the development of enterprises [34]. The effective capture, integration and consolidation of information support the decision-making of the supply chain management team.…”

Research on collaborative decision making of China's photovoltaic supply chain based on competition policy

“…Considering the limited rationality of the supply chain entities in the photovoltaic industry, many experts and scholars use differential game models to study the competition and cooperation issues in the supply chain. Others performed studies on cooperation in the supply chain by constructing differential game models in the forms of performance, incentives, and contracts (Xu et al, 2022;Liu et al, 2022;Zhu, G., 2021). The differential game model can be used to study the competition and cooperation problems in the supply chain.…”
