摘　　要：在区块链背景下,考虑消费者的绿色偏好,构建由农户、物流服务商和超市构成的三级绿色农产品供应链,并建立Stackberg模型。通过理论推导和数值仿真,对比分析在区块链技术下政府支出相同时不同补贴策略的补贴效果。结果表明:区块链技术能降低企业的期间费用,但期间费用影响系数会负面影响绿色度及各成员利润;分别以绿色度、供应链各成员利润作为补贴策略的衡量标准,对应的最佳策略分别是补贴农户策略、补贴超市策略;补贴比例、绿色敏感系数、期间费用影响系数的变化不影响产品绿色度和供应链各成员利润在不同补贴方式下的大小排序,即以绿色度为标准时,补贴农户策略始终最佳,以供应链各成员利润为标准时,补贴超市策略始终最佳。In the context of blockchain,considering that consumers have green preferences,a three-level green agricultural supply chain consisting of farmers,logistics service providers and supermarkets was constructed,and a Stackberg game model was established.Through theoretical deduction and numerical simulation,the subsidy effect of different subsidy strategies with the same government expenditure under the application of blockchain technology was compared and analyzed.The results show that:blockchain technology can reduce the period cost,but the period cost impact factor is negatively affecting greenness and the profits of each member;The greenness and the profit of each member of the supply chain are taken as the measurement criteria of government subsidy strategy,and the corresponding best strategies are subsidy farmer strategy and subsidy supermarket strategy respectively.The changes of subsidy ratio,green sensitivity coefficient and period cost impact factor do not affect the order of product greenness and the profits of each member of the supply chain under different subsidy methods,that is,if greenness is taken as the standard,the subsidy strategy of farmers is always the best,and if profit of each member of the supply chain is taken as the standard,the strategy of subsidizing supermarkets is always the best.
