非线性市场需求下考虑利益关系约束的农产品供应链参与主体决策研究

Research on the Decision Making of Agricultural Supply Chain Participants with the Constraints of Interest Relationship under Nonlinear Market Demand

基于二级农产品供应链,在非线性市场需求环境中,研究强、弱两种利益关系约束下农产品供应链参与主体的最优决策。通过建立利润函数对比最优决策,并利用算例验证结论和探讨利润变化趋势,以提出合理的政策建议。研究表明:在收益共享契约下,强利益约束能使各参与主体获取超额利润,且参与主体的最优决策更贴近保障农产品供需稳定方向;收益共享系数在可行取值域内的增大,对农产品生产商更有利。

Based on two-echelon agriculture supply chain, optimal policy for participants was analyzed with the constraints of strong and weak interest relations under the nonlinear market demand environment.Some proper suggestions were proposed by establishing profit function to compare optimum policy,and by using numerical example to verify the conclusions and discusses profit trends. Research indicated that the strong interest constraint based on revenue sharing contract could make participants obtain excess profits and promote participants＇behaviors to approach the direction of ensuring supply and demand stably.The increase of profit sharing coefficient in the feasible value domain was more favorable for the agricultural producers.
