| In the fresh food supply chain,the main node enterprises hold different private information.Due to the lack of effective information sharing mechanisms,information asymmetry between the upstream and downstream of the supply chain can occur.Enterprises in the supply chain often take advantage of this information asymmetry opportunity to provide false information to cooperative enterprises in order to seek higher profits.However,the existence of false reports can undermine the trust between nodes in the fresh food supply chain,affect the overall operational efficiency of the fresh food supply chain,and damage the overall profit of the supply chain.Therefore,certain measures need to be taken to suppress the occurrence of false reports.Block chain,as a new trust reconstruction technology supported by Industry 4.0,takes advantage of its characteristics of openness,transparency,traceability,and non tampering,which is very effective in suppressing the occurrence of false reporting.However,when enterprises adopt block chain technology,it is bound to bring additional costs.How to balance the benefit relationship between block chain technology application decisions and suppressing false reporting in the fresh food supply chain,and ensure the healthy and s Tab development of the fresh food supply chain,is a topic worthy of in-depth research.Based on this,this article takes a two-level fresh food supply chain composed of a supplier and a retailer as the research subject,considering the decision-making process of whether to apply block chain technology when there is false reporting behavior,and analyzes the impact of changes in the application cost of block chain technology on the game player’s strategy selection.Firstly,the reasons for the occurrence of false reporting in the fresh supply chain,the impact on the supply chain,and the feasibility,value,and pain points of applying block chain technology are analyzed.The analysis shows that block chain technology has significant value in suppressing false reporting in the fresh supply chain,but there are also certain obstacles,and further research is needed on the application decision-making issues of supply chain entities.Therefore,next,under the consideration of misrepresentation behavior,an evolutionary game model involving both suppliers and retailers was established.Through equilibrium analysis and numerical example analysis of the model’s evolutionary s Tab point,it was found that,without the impetus of external factors,the supplier’s decision-making evolution results tend to not apply block chain technology,and suppliers always have misrepresentation behavior,thereby damaging the overall interests of the fresh food supply chain,Retailers have selectively evolved towards applying block chain technology based on different situations of misrepresentation of gains and losses.Then,in the case where the evolution result of the game model between the two parties is not ideal,the government policy incentive factors are introduced,and the government is regarded as the third party in the game.A third-party game model is constructed,and a numerical example analysis is designed.Matlab software is used to analyze the initial willingness of the game party to choose a strategy,the application cost of the block chain,and the impact of government incentive subsidies on the game entity’s strategy selection.The study found that when the government adopts reasonable incentive policies to actively promote the application of block chain technology in the fresh food supply chain,both suppliers and retailers will choose to apply block chain technology under certain constraints.As the cost of block chain applications increases,the strategic choices of suppliers and retailers will evolve from applying block chain technology to not applying it,and the strategic choices of retailers are more sensitive to the increase in block chain application costs.Finally,summarize the research conclusions and propose corresponding strategic recommendations for government policy formulation and fresh food supply chain members’ application decisions on block chain technology.The evolutionary game model for the application of block chain technology among stakeholders in the fresh food supply chain considering fraudulent reporting behavior established in this article not only enriches the research system and modeling methods in the field of fresh food supply chain coordination,but also facilitates the application of block chain technology in the fresh food supply chain;It also plays a certain role in promoting the application and decision-making of the new generation of information technology represented by the block chain in the fresh food supply chain,helping supply chain members achieve mutual benefit and win-win results,and improving the operational efficiency and quality of the fresh food supply chain. |
