供销合作社合作行为演化博弈及其稳定性分析——以“振兴乡村经济”战略背景为视角

Evolutionary Game of Cooperative Behavior of Supply and Marketing Cooperatives and Its Stability Analysis——Taking Perspective of Strategic Background of “Revitalizing Rural Economy” Cooperations

如何深化供销合作社改革、促进供销合作社合作、提升为农服务水平、振兴乡村经济,是当前我国政府面临的一项艰巨挑战。在"振兴乡村经济"战略背景下,选取两供销合作社为博弈主体,在有限理性的前提下,利用演化博弈的相关知识,构建了供销合作社合作行为演化博弈模型,对供销合作社的合作行为及其稳定性进行了研究,并对影响系统稳定性的相关因素进行了分析。结果表明:在一定范围内,增加超额收益、减少合作成本、加大政府项目资金投资、增加违约补偿金、收益分配和成本分摊的合理设定有利于促进供销合作社之间的稳定合作。根据研究结论对政府及相关部门提出建议,以期为新形势下供销合作社的深化改革提供借鉴。
