Game Simulation Research Of Supply Chain Member Enterprises Implementing Blockchain Technology

With the increasing division of social divisions and the diversification of consumer demand,the era of supply chain competition has arrived.As a large-scale collaborative tool,blockchain is naturally applicable to the supply chain field,and can effectively adjust the trust,traceability and other issues of information flow,logistics,capital flow in the supply chain.However,due to the blockchain technology as an emerging technology,the utilization rate of member companies in the supply chain needs to be improved,and the introduction of technology is affected by many factors.Promoting the introduction of blockchain technology by member companies in the supply chain is a powerful tool for building a modern supply chain.In order to analyze this problem,this paper starts with the analysis of the characteristics of the introduction of blockchain technology into the members of the supply chain,and designs a two-level supply chain evolutionary game model consisting of two populations of suppliers and retailers.By calculating the evolutionary stability strategy and using the Any Logic8.3 software to construct the system dynamics simulation to verify the model results,this paper has obtained four main conclusions.(1)Low cost,strong government incentives,generous additional income,and stable partnerships between superior and inferior enterprises can reach ESS more quickly;(2)The dependence of the superior and lower-level enterprises has a significant impact on the speed at which the population reaches the ESS;(3)The results of ESS can be adjusted by regulating costs,government incentives,and dependence of subordinate enterprises;(4)The initial strategic distribution of the population has a decisive influence on the results;(5)If the enterprises in the supply chain maintain the same use of blockchain technology for a certain period of time,they may be at the saddle point,and the adjustment can be improved by adjusting the external environment.On the basis of the above conclusions,under the circumstances that the external environment is certain,the Pareto improvement will be realized by introducing a contract mechanism between the upstream and downstream enterprises in the supply chain.Calculate the evolutionary stability strategy of introducing the contract mechanism and simulate the model results to obtain the following conclusions.(1)When the penalty is small,there is an optimal cost-sharing ratio,but there may still be results of neither introducing blockchain technology;(2)When the punishment is large,both parties will eventually introduce blockchain technology;(3)The higher the interdependence between suppliers and retailers,the greater the role of contract incentives;(4)When the supplier's dependence is higher,the retailer can achieve the optimal incentive effect by sharing the less cost of the supplier;When the retailer's dependence is higher,the retailer pays more cost to the supplier to achieve the optimal incentive effect.The innovation of this paper is based on comprehensive analysis of the similarity of the application of blockchain technology and evolutionary game theory in the supply chain member companies and the feasibility of application.The evolutionary game model is established to analyze the individual behavior mechanism and the interaction between them.The relationship has obtained the conclusion about the stability of its solution and verified the model conclusion by simulation test analysis,which has certain application value.In addition,the application of evolutionary game theory to the promotion of blockchain technology is a relatively new attempt,and there are few studies available for reference.This paper provides a new perspective for research in related fields.
