[目的]畜产品质量关系消费者的健康和安全,故畜产品质量控制关系国计民生,对此进行研究意义重大。[方法]运用微分博弈方法研究了畜产品供应链质量控制策略问题。考察比较了Nash非合作博弈、Stackelberg主从博弈和协同合作博弈3种模式下畜产品供应链中养殖场户和屠宰加工企业双方的最优质量控制策略。[结果](1)若畜产品供应链总收益分配系数σ∈(0,2/3),则养殖场户与屠宰加工企业间的Stackelberg主从博弈严格优于双方间的Nash非合作博弈;(2)养殖场户与屠宰加工企业间的协同合作博弈是一种集体理性模式,协同合作博弈模式下,养殖场户和屠宰加工企业的质量控制水平与畜产品供应链的最优值函数均大于分散博弈模式下的质量控制水平与最优值函数;(3)导出了能够使养殖场户和屠宰加工企业开展质量协同控制的畜产品供应链总收益分配系数的合理取值范围。[结论]最后,通过数值模拟,验证了所建模型与研究结论的正确性。
