摘要： 考虑一条二级农产品供应链，其中农场和零售商拟采用“物联网+区块链”以应对产出不确定和消费者对农产品安全的担忧。通过构建Stackelberg模型，刻画零售商的定价与农场的产量博弈均衡，分析“物联网+区块链”的影响及供应链成员的采用意愿。研究发现，采用“物联网+区块链”后的销售价格增量等于“物联网+区块链”缓解消费者担忧上的效益和单位变动成本的平均值。只有在“物联网+区块链”的净效益（缓解消费者担忧上的效益和单位变动成本之差）较高时，需求（或计划产量）才会增加。总体而言，农场比零售商更愿意采用“物联网+区块链”，但当农产品质量较高时，零售商更愿意采用。通过基于收益共享的Nash谈判，双方同时采用的可能性增加，并能实现帕累托改进。数值实验验证了理论结果。

Abstract: We consider a two-tier agricultural supply chain where a farm and a retailer propose to adopt Internet of Things and blockchain technology (IoT+BCT) to deal with yield uncertainty and consumers’ safety concern about the agri-product. By constructing a Stackelberg model, the equilibrium of the pricing and production decisions between the retailer and the farm is analyzed, along with the impact of IoT+ BCT and the adoption willingness of supply chain members. The study finds that the increase in the retailer’s price after adopting IoT+BCT equals the average of the benefit of IoT+BCT in alleviating consumers’ concern and the unit variable cost. However, demand (or planned production amount) will only increase when the “net” benefit of IoT+BCT (defined as the difference between the concern alleviation benefit and the variable cost of IoT+BCT) is sufficiently high. Generally, the farm is more willing to adopt IoT+BCT than the retailer. The retailer is more likely to adopt the IoT+BCT when the quality of the agricultural product is higher. Through Nash bargaining based on revenue sharing, the likelihood of both agents concurrently adopting IoT+BCT is enhanced, leading to potential Pareto improvement. Numerical experiments are conducted in order to validate the theoretical results and to derive additional managerial insights.
