绿色农业供应链协同创新的微分对策研究

Research on Differential Game of Collaborative Innovation in Green Agricultural Supply Chain

推动农业绿色转型是实现碳中和目标的重要举措。本文通过引入农产品绿色度对供应链收益的影响,运用微分对策模型研究了由农业公司和农户组成的绿色农业供应链的协同创新问题。分析了Nash非合作博弈、Stackelberg主从博弈和协同合作博弈不同状况下各方的均衡策略。结果表明,相较于Nash非合作博弈,Stackelberg主从博弈下,能够显著改善农户的绿色创新努力程度、双方的收益水平,以及供应链的农产品绿色度;协同合作博弈下,双方的专业分工和绿色创新努力程度、供应链的农产品绿色度及整体收益均达到最高。研究结论为绿色农业供应链协同创新提供了理论指导。

Promoting the green transformation of agriculture is an important measure to achieve the goal of carbon neutrality.By introducing the influence of agricultural products’green degree on the benefit of the supply chain,this paper used the differential game model to study the collaborative innovation of green agricultural supply chain composed of an agricultural company and a farmer.The equilibrium strategies in three different situations of Nash non-cooperative game,Stackelberg leader-follower game and cooperative game are analyzed.The results show that,compared with the Nash non-cooperative game,in the Stackelberg leader-follower game,the green innovation efforts of the farmer,the benefits of both parties,and the agricultural products’green degree of the supply chain can be significantly improved.In the collaborative game,the specialization and green innovation efforts of both parties,as well as the agricultural products’green degree and overall benefit of the supply chain all reach the highest level.The research results provide theoretical guidance for collaborative innovation of the green agricultural supply chain.
