考虑利他互惠动态演进的农产品双边质量提升

Bilateral Quality Improvement of Agricultural Product under Altruistic Reciprocity Evolution

考虑超市利他互惠信息非对称、动态演进性,构建农产品双边质量努力决策博弈模型,采用逆向归纳法求解利他互惠信息动态演进过程中的双边质量努力水平,从主观和客观两个维度分析超市利他互惠动态演进对供应链效率和公平度的影响。在超市利他互惠信息动态演进过程中:超市总是选择最优的农产品质量检测努力水平,农产品加工商的质量努力水平受超市利他互惠强度正向影响;超市利他互惠且信息对称不仅能有效提高农产品供给质量和供应链主客观效率,同时能获得较高的供应链收益分配公平度,促进高质量农产品稳定供给和农产品供应链稳定运作。

Considering the asymmetry and dynamic evolution characteristics of supermarket’s altruistic reciprocity information,the backward induction was applied to solve the optimal bilateral quality effort in the dynamic evolution process of altruistic reciprocity information.Then,the effects of altruistic reciprocity dynamic evolution on the efficiency and fairness of supply chain were analyzed.By mathematical model and numerical analysis,the conclusions were as following:Firstly,supermarket would always choose the best agricultural product quality inspection effort level,and the quality effort level of agricultural product processor is positively affected by the intensity of supermarket altruistic reciprocity.Secondly,when supermarket is altruistic and information is symmetric,it can not only effectively improve the quality of agricultural product,but also can improve the efficiency and fairness of supply chain.Finally,supermarket’s altruistic reciprocity and symmetry information can improve both the stable supply of high-quality agricultural product and supply chain operation.
