近年来,世界范围内的食品安全问题频频发生,引发了全球性的消费者信任危机,而企业实施食品可追溯体系能够增大不同信任属性食品的差异化程度,提高供应链管理效率,从而能提升食品的质量安全水平,是解决这一问题的途径之一。本文的创新之处在于试图将垂直差异化博弈模型应用于食品可追溯体系研究,并通过Matlab模拟计算研究企业实施食品可追溯体系对消费者、生产者剩余以及社会福利的影响,以探究食品行业实施可追溯体系的效率。研究结果表明,消费者因食品安全程度提高而获得了更多收益,提高了效用水平。高质量食品生产者剩余与消费者剩余增量之和超过了低质量食品生产者剩余的减少量。总体而言,社会总福利因食品安全水平的提高而增加。
In recent years, the worldwide food safety problems frequently occur, triggering a global crisis of consumer confidence, and enterprises to implement food traceability system can increase the degree of differentiation of different trust attributes of food, improve supply chain management efficiency, which can Improving the quality and safety of food is one of the ways to solve this problem. The innovation of this paper is trying to apply the vertical difference game theory to the food traceability system and researching the influence of enterprises implementing food traceability system on consumers, producer surplus and social welfare through Matlab simulation to explore the food industry The efficiency of implementing a traceability system. The results show that consumers have gained more benefits due to the increased food safety and raised the level of utility. The sum of the surplus of high-quality food producers and the surplus of consumers exceeds the remaining reduction of low-quality food producers. Overall, the total welfare of society has increased due to the increased level of food safety.
