摘要
【目的】针对农产品供应链质量管理中的双重边际化、质量投资不足问题,探讨了公司作为供应链主导方、农户决定农产品质量水平情况下,农户、公司构成的二级农产品供应链的质量协调问题。【方法】运用动态博弈理论分析了集中决策下的供应链均衡结果,以及传统批发价契约下的供应链决策,在此基础上应用博弈理论、最优化理论设计了质量投资补贴契约。【结果】批发价契约下供应链的最优质量水平、供应链总利润均低于集中决策下的情形;投资补贴契约下,农产品最优质量水平等于集中决策下的质量水平,最优价格与批发价正相关,最优质量、最优价格、公司利润均大于传统批发价契约下的均衡结果,农户利润则不变。研究也发现,质量需求弹性越大、质量投资系数越小的农产品,采用投资补贴契约后、公司的利润提升越大。【结论】投资补贴契约下的农产品供应链,相比批发价契约能够得到帕累托改进,同时农产品质量投资也将得到更好的激励。
【Objective】Aiming at double marginalization and insufficient quality investment in the quality management of agricultural product supply chain, this paper probed into the quality coordination of the secondary agricultural product supply chain formed by the companies as the leading party of the supply chain and farmers households as the party that decides the quality level of agricultural products.【Method】 The equilibrium results of supply chain under the centralized decision and the supply chain decision under the traditional wholesale price contract were analyzed by dynamic game theory. On this basis, the quality investment subsidy contract was designed by using game theory and optimization theory. 【Result】It was found that both the optimal quality level and the total profit of the supply chain under the wholesale price contract were lower than those under the centralized decision. Under the investment subsidy contract,the optimal quality of agricultural products was equal to the quality under the centralized decision, the optimal price was positively correlated to wholesale price, and the optimal quality, optimal price, and the companys' profits were greater than the equilibrium results under wholesale price contract while the farmers' profits remained the same. It was also observed that, for the agricultural products with higher quality demand elasticity and lower quality investment coefficient, the higher profits could be gained by the company after adopting the investment subsidy contract.【Conclusion】 The supply chain of agricultural products under the investment subsidy contract can gain Pareto improvement compared with the wholesale price contract, and the investment in the quality of agricultural products will be better encouraged.
