摘　　要：社区支持农业(CSA)为生产者与消费者构筑了有机衔接和重复博弈的共生关系,并促进这种共生关系向对称性互利共生演化。本文基于共生理论,剖析了CSA中生产者与消费者的共生关系机理和演化动力,在做出研究假设的前提下构建并分析二者处于不同共生关系中的Logistic模型,求解相应的均衡点和稳定性条件。研究表明:CSA中生产者与消费者存在共生关系时的产出效益高于相互独立时的产出效益;共生系数的大小决定二者产出效益的高低;在互利共生关系中二者都能获得相对均衡的共生效益。以此为依据,本文为促进CSA模式的发展提出切实可行的建议。Community Supported Agriculture(CSA)builds the symbiotic relationship of organic convergence and repeated games for producers and consumers,and promotes the evolution of this symbiotic relationship to symmetric mutualism.Based on symbiosis theory,this paper analyzes the symbiotic relationship mechanism and evolutionary power between producers and consumers in CSA,constructs and analyzes the Logistic model of the two in different symbiosis relationships under the premise of making research hypotheses,and solves the corresponding equilibrium points and stability conditions.The research shows that the output benefit of the symbiosis between producers and consumers in CSA is higher than that of the independence.The symbiosis coefficient determines the output efficiency of the two.In the mutually beneficial symbiotic relationship,both can obtain a relatively balanced symbiotic benefit.Based on this,this paper puts forward feasible suggestions for promoting the development of CSA model.
