考虑产出率影响销售价格的农产品供应链利益协调模型

Benefit Coordination Model of Agricultural Products Supply Chain Considering the Effect of Output Rate on Sales Price

以农户和超市构成的二级农产品供应链为研究对象,假设超市占主导地位,分析产出随机且能够影响销售价格的情境下农产品供应链利益协调问题。分别建立集中、分散及不同协调契约下的决策模型,结果表明:二部定价契约和Shapley值法分配契约均可使供应链最优利润达到集中决策水平;Shapley值法分配契约能直接实现双方利益的协调,而二部定价契约下农户需要向超市支付一定的转移费用才能实现协调。

Taking the secondary agricultural product supply chain composed of farmers and supermarkets as the research object,assuming that supermarkets are dominant,this paper analyzes the coordination of agricultural product supply chain benefits under the situation that the output is random and can affect the sales price.The decision-making models under centralized,decentralized and different coordination contracts are established respectively.The results show that both the two-part tariff contract and Sha-pley value method distribution contract can make the optimal profit of the supply chain reach the centralized decision-making level.Shapley value method distribution contract can directly coordinate the benefits of both parties,while farmers need to pay a certain transfer fee to supermarkets to achieve coordination under the two-part tariff contract.
