基于农户社会责任的部分保证价格合同研究

Research on Partial Guaranteed Price Contract Based on Farmers' Social Responsibility

考虑农户的社会责任,研究了农户与企业的部分保证价格合同(PGP)设计问题,并分析农户社会责任对PGP合同以及供应链整体效益的影响。研究表明,当农户实施社会责任行为时,其存在一个最优部分保证价格合同,且农户社会责任行为能提高供应链整体效益。此外,对于农户社会责任的部分保证价格合同模型做了进一步扩展,当农户分配比例存在上限且分配比例上限β≥0.5时,农产品供应链仍可以实现最优收益;当农户可以预期到企业将提供PGP合同时,农产品供应链最优收益将会提高。

Considering the social responsibility of the farmers,the design of the partial guaranteed price contract(PGP)of the farmers and enterprises is studied,and the impact of the social responsibility of the farmers on the PGP contract and the overall benefit of the supply chain were analyzed.The study shows when farmers implement social responsibility behavior,there is an optimal part to guarantee the price contract,and the social responsibility behavior of farmers can improve the overall efficiency of the supply chain.In addition,the model of partial guaranteed price contract based on farmers’social responsibility is extended.When the distribution ratio of farmers has an upper limit and the upper limit of distribution ratioβ≥0.5,the agricultural product supply chain can still achieve the optimal income.When the farmers can realize the company providing PGP contract,the optimal supply of agricultural products supply chain will increase.
