中文摘要:
      针对农产品存在细分市场需求和政府补贴力度不同的现象,提出对可持续农产品和环保型农产 品供求水平提升的优化建议与政府补贴策略;在假定政府对3个异质性制造商采取差异化补贴的基础上,综合考虑农产品的属性水平和消费者的不同偏好程度,并运用 Stackelberg博弈理论建立了农产品可持续供应链下的供求模型,政府根据社会福利最大化目标制定出最优的补贴政策,以进一步推动可持续供应链的细分市场供求达到均衡状态;最后,通过数值仿真分析了各种参数扰动对相关最优决策结果的影响。结果表明: 政府的补贴政策可以有效降低农产品的售价,增加环保型农产品和可持续农产品的细分市场需求,提升消费者的可持续消费水平,有利于促进经济效益和环保效益的双赢,对供应链的可持续与协调发展具有一定的指导意义和参考价值。
英文摘要:
      In view of the phenomenon of different market segments and different levels of government subsidies for agricultural products, optimization suggestions and government subsidy strategies for the improvement of the supply and demand of sustainable agricultural products and environmentally friendly agricultural products are proposed. Based on the assumption that the government adopts differentiated subsidies for three heterogeneous manufacturers and the comprehensive consideration of the properties of agricultural products and the different preferences of consumers, Stackelberg game theory is used to establish a supply and demand model under the sustainable supply chain of agricultural products and the government formulates the optimal subsidy policy according to the goal of maximizing social welfare to further promote the equilibrium of supply and demand in the market segments of the sustainable supply chain. Finally, the influence of various parameter perturbations on the correlative optimal decision results is analyzed by numerical simulation. The results show that the government’s subsidy policy can effectively reduce the price of agricultural products, increase market demand for environmentally friendly agricultural products and sustainable agricultural products, and improve consumers ’ sustainable consumption levels, which is conducive to achieving a win-win situation for economic and environmental benefits. It has certain guiding significance and reference value for the sustainable and coordinated development of the supply chain.
