摘 要
近年来，我国食品安全问题频繁发生，政府不断的提出各种监督、解决的策略，但食品安全问题仍是屡禁不止。随着供应链的提出，商流、物流环节的增加，链条的延长更是增加了食品安全的风险，使得食品质量安全信息缺失呈现递增效应。这种食品市场上不对称的不完全信息和对称的不完全信息的客观存在对社会、企业都造成了不可估量的经济损失。食品作为人类生存和延续的基本物质条件，其质量安全问题不仅仅是经济问题与社会问题，在特定条件下也会转变成政治问题。因此，食品安全问题成为全球的焦点问题之一是无可非议的。近年来，以国内、国际市场需求和发展变化为背景，从中央到地方都非常重视食品质量安全问题。
本文分为四个部分，第一部分为引言，主要论述选题背景、意义。通过文献综述的方式，对国内外在这个领域的研究状况进行分析，结合当前食品行业的实际情况，提出本论文主要的研究问题——基于国内外相关研究成果，在其良好的基础之上，辨证吸纳已有研究成果，结合我国的实际发展和现实需要，针对食品安全信息有效传递的主体行为分析。第二部分主要通过信息不对称理论，交易费用理论，博弈论对信息传递的主体行为进行理论分析，从多层面、多角度、多学科展开分析。在理论分析的基础上，按照信息传递的差异化对食品安全的影响，结合与食品价格、成本、生产效益、规制的社会效果等的联系，构建食品安全信息传递主体行为数学模型。第三部分主要把近五年的食品安全事件的汇总罗列并分类，找出供应链中食品安全信息传递发生问题的关键点。通过几个鲜为人知的实证案例验证第二部分的数学模型。第四部分为论文的总结，并针对问题提出对应的政策建议，规范并完善食品市场，减少食品安全问题的发生。

ABSTRACT
In recent years, food safety has become a public concern, therefore, several strategies for this problem have been proposed by government, however, the food security accident still happen. With the recommends of supply chain, the increase of business flow and logistics and the extend of the whole chain, the risk of food safety and food quality information loss are increasing. The asymmetric and symmetric incomplete information on food market have caused incalculable economic losses to the society and enterprise. Food is a basic material condition for human survival and continuation, its quality and safety issue is not just economic issues and social issues, under certain conditions; it will be transformed into a political issue. Thus, there is no doubt that food security has become one of the world''s focuses. During these years, under the background of the demand of domestic to international market, the development and change, the food quality and safety issues has been attached great importance from the central to the local.
This paper is divided into four parts; the first part is an introduction, which discusses the background, significance of the subject. At the beginning, the analysis of home and abroad research in this field has been put forward by literature review. With the current actual situation of the food industry, the research questions of this thesis has been proposed, that is, based on home and abroad relevant research results, dialectical citation of existing research results, and combined with China''s actual development and the practical needs, our research talks about the main behavior analysis of food safety information and effective delivery. The second part mainly describes the theoretical analysis of multi-level, multi-angle and multi-disciplinary to information transfer main behavior by asymmetric information theory, transaction cost theory and game theory. Based on the theoretical analysis and the impact on food safety by the difference of the information transmission, combined with the contact of food prices, costs, production efficiency, social effects and so on, mathematical model of the main behavior of food safety information transmission has been build. At the third part, it listed food safety events in the past five years, identified the key points about the supply chain of food safety information transfer. It verified the mathematical model in second part by several little-known empirical cases. The last part is the summary of the paper, some policy recommendations for the corresponding problem were came up to standardize and improve the food markets, reduce food safety problems.
Keywords: food safety, information transfer, main behavior
