合同农业供应链的最优决策——基于纳什讨价还价模型

Optimal Decision-making in Contract Agricultural Supply Chain--Based on Nash Bargaining Model

合同农业对稳定农产品价格、确保农民合理收益、抵御市场价格风险具有一定的积极作用,但合同农业中的公平问题值得关注。在随机收益率下,构建由一个风险中性的农业企业和一个关注公平的风险厌恶型农民组成的合同农业供应链模型,根据纳什均衡讨价还价模型,分析公平性对风险厌恶型农民在合同农业供应链中最优决策的一些参数。结果表明,在纳什交易框架内,具有公平关注的农民和公平中立的公司组成的合同农业供应链可以通过讨价还价模型实现均衡解决方案。

Contract farming has a positive effect on stabilizing agricultural products prices,ensuring farmers'reasonable returns,and resisting market price risks,but the issue of fairness in contract farming deserves attention.Under the random rate of return,a contracted agricultural supply chain model was constructed consisting of a risk-neutral agricultural enterprise and a risk-averse farmer who cares about equity.Based on the Nash equilibrium bargaining model,some parameters of optimal decision-making were analyzed in the contracted agricultural supply chain for fairness to risk-averse farmers.The results showed that within the framework of the Nash transaction,a contracted agricultural supply chain composed of farmers with fair concerns and fair and neutral companies can achieve a balanced solution through a bargaining model.
