【摘要】：近年来，食品质量安全事件在全球范围内频频发生，我国食品质量安全领域面临着重大挑战。一方面，与消费者和政府监管部门相比，食品企业拥有关于产品的信息优势，许多企业以此来谋取不法利润；与此同时，，信息不对称问题也存在于食品供应链上下游各个节点企业之间，这又导致供应链上下游各个节点企业之间的关系难以协调以确保安全食品的供给。众多发达国家和地区的实践证明，具备完整的生产信息记录与披露功能的食品可追溯体系能够有效提高食品质量安全水平，但在我国起步较晚且建设不完善。本文从整个食品供应链的角度出发，采取定性与定量相结合的研究方法，探究食品可追溯体系在供应链中建立的关键影响因素并提出对策建议。首先，以文献综述的形式，分别从食品可追溯体系的概念与内容、所发挥的功能作用和所涉及的相关主体行为等多个角度，归纳和总结现有研究成果，并在此基础上进行分析和评述。其次，通过对一个包含若干个同质的食品原材料供应商、一个食品生产加工商以及消费者的三级供应链系统进行建模，论证了可追溯能力对食品供应链上下游节点企业以及整个供应链食品质量安全水平的影响，定量分析了食品可追溯体系在供应链中建立的必要性。再次，在演化博弈的基础上，构建了包含食品供应链上游节点企业原材料供应商与下游节点企业生产加工商两个群体的二级供应链系统模型，研究了使供应链上下游节点企业在有限理性的前提下共同建设食品可追溯体系的合作机制，得出了食品可追溯体系在供应链中建立的关键影响因素。最后，在全面分析我国食品可追溯体系建立与实施现状与难点的基础上，结合模型所得结论，提出食品可追溯体系在供应链中建立与实施的对策建议。
[Abstract]:In recent years, food quality and safety incidents occur frequently all over the world, and China's food quality and safety field is facing major challenges. On the one hand, compared with consumers and government regulators, food enterprises have information advantages about products, and many enterprises seek illegal profits in this way; at the same time, the problem of information asymmetry also exists. The practice in many developed countries and regions has proved that the food traceability system with complete production information recording and disclosure function can effectively improve the food supply. Quality and safety level, but in our country started late and construction is not perfect.
From the point of view of the whole food supply chain, this paper takes qualitative and quantitative research methods to explore the key factors affecting the establishment of food traceability system in the supply chain and puts forward countermeasures and suggestions.
Firstly, the existing research results are summarized and analyzed in the form of literature review from the concepts and contents of food traceability system, its functions and related subjects.
Secondly, by modeling a three-tier supply chain system consisting of several homogeneous food raw material suppliers, a food manufacturer and a consumer, the paper demonstrates the impact of traceability on the food quality and safety level of upstream and downstream node enterprises in the food supply chain and the whole supply chain, and quantitatively analyzes the food traceability. The necessity of establishing the system in the supply chain.
Thirdly, on the basis of evolutionary game theory, a two-echelon supply chain model is constructed, which consists of two groups: the raw material supplier of upstream node enterprises and the manufacturer and processor of downstream node enterprises. The key factors affecting the establishment of food traceability system in the supply chain are obtained.
Finally, on the basis of a comprehensive analysis of the current situation and difficulties of the establishment and implementation of food traceability system in China, and combined with the conclusions of the model, the countermeasures and suggestions for the establishment and implementation of food traceability system in the supply chain are put forward.
