Frequent food safety and quality issues in the fresh agricultural products industry is a reminder that rapid and efficient preventive measures are urgently needed.From a supply chain perspective,this paper in-troduces the blockchain technology,and by combining the supply chain with the blockchain,and considering resources limitation and consumer preference,establishes a game model respectively for the supplier and seller on the supply chain based on blockchain technology investment,as well as four viable strategic combinations.Next,using the evolutionary game method,it studies the equilibrium conditions under the four strategic com-binations and the sufficient conditions for the supplier and seller to choose the blockchain technology,and via numerical simulation,analyzes the impact of internal and external factors on the profit of the supply chain en-terprises.This research will help enrich the theoretical research on the fresh agricultural product supply chain and better realize the application of the blockchain technology by fresh agricultural products enterprises.First,under the arrangement where the government is to build a blockchain technology platform and pro-vide technical subsidies,and the fresh food supplier is to make freshness preservation efforts,and by comprehen-sively considering the freshness of the fresh products and the impact of the blockchain technology on the mar-ket demand for fresh products,this paper establishes two Stackelberg game models of the supplier and seller re-spectively when the blockchain technology is and is not applied and studies the optimal decision and optimal profit of the supplier and seller under different strategic combinations.Furthermore,with optimal profit as the objective,it constructs the income payment matrix under the four strategic combinations,and through evolu-tionary game analysis,studies the stable equilibrium condition of the fresh agricultural product supply chain en-terprises and the optimal decision regarding investment in emerging technologies.Finally,in a numerical simu-lation example,it looks into the impact of consumer freshness sensitivity coefficient,product false advertising sensitivity coefficient,and government technology subsidization on the profit of the supplier and seller.Through the above steps,the following conclusions are reached:(1)Only when the consumer freshness sensitivity coefficient,the consumer sensitivity coefficient to false product information,and government's tech-nical subsidies are within a certain range,will the supplier and seller simultaneously choose to use the block-chain technology platform;(2)When the equilibrium condition for the supply chain enterprises to apply block-chain technology is met and both supply chain enterprises use the blockchain technology,the level of freshness preservation efforts will be the highest;(3)In addition,the consumer's sensitivity coefficient to freshness is not the higher the better,for when excessively high,it will affect the profit of the supplier,and government subsidi-zation can encourage the enterprises to use the blockchain technology platform.The result of this study will,to a certain extent,help with government policy-making and corporate decision-making in blockchain technol-ogy investment and the supply chain enterprises should actively apply emerging technologies for information disclosure,increase R&D investment,make more preservation efforts,and reduce costs;while the government should step up technological investment,formulate incentive policies,and assume a leading role in managing consumption values and raising consumer awareness to form a three-party collaboration to accelerate the appli-cation of the blockchain technology.
