Research on Supply Chain Information Transparency Mechanism Based on Blockchain

Abstract Supply chain information sharing and information transparency help to promote the efficiency of supply management. This study applies the idea of evolutionary games to establish a supply chain information sharing game model on blockchain. The model takes the supply chain as the research subject, solves the game equilibrium points of information supply and demand sides, and explores the dynamic evolution process of relevant factors on the choice of information sharing strategy of the game subject. Subsequently, the software is used to perform numerical simulation analysis of the constructed game model to explore the influence of relevant variables on the evolution of strategy selection during the evolution of the game. Finally, the blockchain-based mechanism for sharing supply chain information is established based on simulation results. From the simulation results, it can be seen that in the simulation analysis of the incentive factor θ of subsidies and penalties of the relevant departments, when θ =1.1 and θ =1.9, the larger the value of θ is, the more initial points converge to the point (1,1), and the probability of the game evolution results of subject 1 and subject 2 is “information sharing” is greater. Therefore, the establishment of incentive mechanisms is a direct way to reduce the cost and risk for node enterprises involved in supply chain information sharing activities. At the same time, a reasonable penalty mechanism can ensure fairness in the supply chain and maintain mutual trust among member enterprises.
