公平关切与创新投入下的闭环供应链决策优化研究

Research on Decision Optimization of Closed-loop Supply Chain under Fairness Concern and Innovation Investment

考虑回收商公平关切与制造商创新投入问题,分别构建公平关切和创新投入与否的闭环供应链决策模型,并针对回收商不利不公平厌恶设计基于成本分担的供应商前向整合契约,探讨公平关切程度、创新成功率和成本分担比例对供应链决策的影响。研究发现,回收商对公平的关注是回收系统内部利润分配的一种手段,也是一种“利己损他”行为。创新成功率的提高,有助于供应链系统利润的增长,但供应商“搭便车”的行为不利于制造商创新和供应链长期稳健性。当公平关切程度和成本分担比例满足一定条件时,基于成本分担的供应商前向整合契约不仅能避免回收商“利己损他”行为,约束供应商“搭便车”的机会主义行为,还能进一步优化决策模型,实现供应链Pareto改进。

Considering the fairness concern of recyclers and the innovation investment of manufacturers,the closed-loop supply chain decision-making models of fairness concern and innovation investment are constructed respectively,and the suppliers forward integration contract based on cost sharing is designed for the disadvantage and unfairness of recycler.The influences of fairness concern,innovation success rate and cost sharing ratio on supply chain decision-making are discussed.The results show that the recyclers concern for fairness is a means of profit distribution within the recycling system,and it is also an act of“harming others for one s own benefit”.The improvement of the success rate of innovation is conducive to the profit growth of the supply chain system,but the“free-riding”behavior of suppliers is not conducive to the innovation of manufacturer and the long-term stability of the supply chain.When the degree of fairness concern and the proportion of cost sharing meet certain conditions,the forward integration contract of suppliers based on cost sharing can not only avoid the“harming others for one s own benefit”behavior of the recyclers,but also restrain the suppliers opportunistic“free-riding”behavior,and further optimize the decision-making model to achieve Pareto improvement of supply chain.
