Abstract
Firstly, this paper described the structural characteristics of China's food system and the profile of food safety problems, and introduced the improvement in laws and regulations and the trends of administrative measures in food safety management. Because the information asymmetry is the main cause of imbalance on food safety market, as a means of information communication, the traceability system plays an important role in developed countries' food safety management. Based on the existing operation status in China's food system and case studies of Beijing's vegetable industry, this paper defined the characteristics and conditions under which this system can operate in China.
