Research on the Formation Mechanism of Food Safety Risks from the Perspective of Food Chain and Game Theory

Food security, as a basic livelihood issues, is an important indicator of people's lives to measure the quality of a country. In this paper, the perspective of research focusing on food chain, we present that the interests of the game and information asymmetry are the major trigger factor to the formation of risk, and build the relation diagram of "subject risk" for food security. Then we analyze the formation mechanism of food safety risk based on the production-supply-distribution, government, social supervision and consumption. Therefore, we regard that the government should coordinate and interact with other subjects as the main food safety regulator, and reduce information asymmetry and interests of the game between the constituent subjects through the development of relevant mechanisms and public policy, thus effectively reducing food safety risks.
