摘　　要：农户和合作社间的信任问题一直制约着我国农民专业合作社的发展,区块链技术的出现为解决这一难题提供了新的契机,而一项新技术出现最亟待解决的问题之一便是各参与方的采纳问题。本文建立了农户和合作社上链行为的网络演化博弈模型,运用演化博弈理论描述博弈主体的决策机制,用复杂网络刻画系统内个体之间的交互行为,深入研究相关因素对农户和合作社上链行为的影响作用,并通过案例分析与数值实验检验了模型的正确性和有效性。研究表明:当价格敏感系数和质量成本系数较高时,农户和合作社的上链意愿呈断崖式下降;农户和合作社上链意愿随着需求质量弹性的增加先小幅波动,再呈指数式增加,后转为缓慢增加;服务收益系数对农户和合作社的上链愿意无显著影响。Farmers′participation in cooperatives is one of the main business characteristics of China′s rural economic development.Meanwhile,professional farmers′cooperative is an important carrier to realize the effective connection between farmers and market,which is related to the quality and safety of agricultural products and the process of farmers’poverty alleviation and prosperity.However,the information asymmetry between farmers and cooperatives leads to the problems of moral hazard and adverse selection,causing a serious trust crisis between the two.The issue of trust between farmers and cooperatives has been restricting the development of professional farmers’cooperatives in China.The emergence of blockchain technology provides a new opportunity to solve this problem.Blockchain is a distributed shared ledger and database,which is decentralized,open and transparent,unchangeable,anonymous and secure,and can effectively solve the trust crisis between farmers and cooperatives.One of the most urgent problems in the emergence of a new technology is the issue of adoption of each participant.To this end,this paper conducts research on the adoption of blockchain technology by farmers and cooperatives.In fact,the decision-making of blockchain technology adoption of farmers and cooperatives is a game process between them.Due to the limited rationality of farmers and cooperatives in the process of game decision-making,they need to continuously improve strategies through learning and imitation to increase profits.Evolutionary game theory is an analysis method that focuses on the game subject of limited rationality,combining with the idea of biological evolution theory though the method of combine game analysis and dynamic evolution process.At the same time,the“many-to-many”interaction between farmers and cooperatives in reality constitutes a complex network with topological statistical characteristics.The game strategy of farmers and cooperatives will change with the change of network structure,which is essential
