考虑绿色度的双渠道农产品供应链决策协调研究

Study on coordination decision of agricultural products dual channel supply chain considering green degree

考虑消费者绿色偏好的情况下,引入绿色度这一变量,以制造商主导的双渠道农产品供应链为背景,通过建立双渠道供应链Stackelberg博弈模型,得出供应链成员在集中决策和分散决策的最优决策和最优值,结果表明:线上线下市场份额的合理性是双渠道供应链存在的必要条件;集中决策优于分散决策;两种决策模式下的最优值均与绿色研发因子成反比,说明绿色度是提高供应链效益的关键,并通过数值分析来验证结果的真实性.最后,为了促进成员之间的合作,设计二部契约协调,实现供应链协调和帕累托最优,得出该契约设定在一定范围内可以实现供应链成员共赢.

Considering the green preference of consumers,this paper introduces the variable of green degree,takes the dual channel agricultural product supply chain dominated by manufacturers as the background,establishes the Stackelberg game model of dual channel supply chain,and obtains the optimal decision and optimal value of supply chain members in centralized decision-making and decentralized decision-making.The results show that(1)the rationality of online and offline market share is the necessary conditions for the existence of the dual channel supply chain,(2)centralized decision-making is better than decentralized decision-making,and(3)the optimal values of the two decision-making modes are inversely proportional to the green R&D factor,indicating that the green degree is the key to improve the efficiency of the supply chain.The results are verified by numerical analysis.Finally,in order to promote the cooperation between members,we design two-part contract coordination to achieve supply chain coordination and Pareto optimization,and conclude that the contract setting can achieve win-win situation for supply chain members within a certain range.
