摘　　要：针对消费者的异质性需求,构建由农户、合作社和超市组成的异质农产品农超对接三级供应链,建立完全信息下合作社主导的Stackelberg博弈模型,通过引入最低绿色度讨论了两种契约模型对供应链成员决策的影响.研究表明:最低绿色度对两种农产品的最优价格水平、绿色农产品的需求量产生影响,但不会影响普通农产品的需求量;在固定采购价的批发价契约下,限定的最低绿色度是确定的.通过加入成本分担契约、收益共享契约进行契约组合设计,指出组合契约能够提高限定的最低绿色度、绩效价格比和供应链成员的利润,使得供应链的运作效率显著提高.最后利用数值算例对模型结论的有效性进行了分析验证.Aiming at the heterogeneous needs of consumers,a heterogeneous agricultural products farmer-supermarket connecting three-level supply chain composed of farmer,cooperative and supermarket with cooperative-led Stackelberg game models under complete information is established,and the influence of two contract models on decision-making of supply chain members is discussed by introducing lowest green degree.The results show that the limited lowest green degree has an impact on the optimal price level of two kinds of heterogeneous agricultural products and the demand for green agricultural product,but it will not affect the demand for common agricultural product,and under the wholesale price contract with fixed purchase price,the limited lowest green degree is determined.By adding the cost sharing contract and the revenue sharing contract,the contract combination is designed.Furthermore,it is pointed out that the combination contract can improve the limited lowest green degree,performance price ratio and the profits of the supply chain members,and make the operation efficiency of the supply chain significantly improve.Finally,the validity of the model conclusion is verified by numerical examples.
