【正文】 fruit of 30% and 70%.Other countries also generally the supermarkets in order to meet consumer demand significant changes to the original by an independent enterprise engaged in specialized production of valueadded aspects of “internal” andw specifically the establishment of largescale processing and distribution center for agricultural products for cleaning, sorting, indepth processing, packaging and distribution and other valueadded services, through the implementation of HACCP in a large processing center and GMP certification process quality and health and safety, to ensure the quality of food and agricultural link is above three does not have the food supply chain, which is large supermarkets and chain stores to respond quickly to market demands upstream suppliers to enhance the strength and advantages of the processing center part of the function, such as cleaning, sorting and depth of processing and other sectors Youxiang supplier back, making the processing center focused on the processing of agricultural products and expanding the number and type of , this food supply chain is a prehensive, multispecies, multifrequency highvolume and mix of supply chain food supply chain are more concerned about customer satisfaction, through the processing centers to respond quickly to market demand, and realtime on agricultural products and foodstuffs “tailored” and depth of processing, in order to achieve different from the lean agile logistics logistics supply chain tracking and food quality and safety In recent years, the focus of the food supply chain collaboration to ensure delivery of quality from the gradual move to reinforce the quality and safety of food and agricultural products, such as BSE, foot and mouth disease and the emergence of genetically modified products and food quality and safety of track without food supply chain management, so based on quality and safety of the food supply chain to track the food supply chain management has bee important and by the United States and other fresh produce, meat products，w cereals and oilseed rape, and survey findings, three by the food supply chain tracking, food quality and safety in that there are great analysis of these differences, they also found that three agricultural products mon food supply chain management, that there are three driving is also the corporate implementation of the food supply chain management requires analysis examines the question: 1．will help differentiate the marketing of food and agricultural products to improve food and agricultural those small or can not be directly found in food quality and sa。s agriculture industry in less developed regions, due to lack of upstream farmers to connect one end, other end of the link sales market, specializing in the processing of agricultural products among leading enterprises and the corresponding part of agricultural production often out of line with market , Tmiddle part of the food supply chain as a low level of absence and logistics operation, prone to upstream farmers and downstream production of agricultural products sold blindly difficult ．symmetric food supply the emergence of new sales formats, distribution channels are increasingly largescale professional marketw and supermarket monopoly, the traditional sales of agricultural products and food forms have been replaced by supermarkets, and this trend is more and more obvious, and because of its technological level of agricultural products production also tends to intensive management by a few Ahe by the Royal Thai supermarket fresh food supply chain management survey found that 50% of Bangkok39。the same in the United States Food and Drug Administration regulations in the United States and abroad engaged in food production, processing and packaging departments and related organizations in the December 12, 2003 to register the Food and Drug Administration for food safety tracking and tracing, on the allowed unregistered persons engaged in food production and , the food supply chain management is inherent in the market dynamics and the external pressure the government to promote the supply chain, production logistics system The formation of the food supply chain logistics system with the changing content of closely related, particularly in the food and agricultural production logistics system evolving situation, for people to create a highly efficient food supply chain management paradigm provides the to food and agricultural products logistics stage of development, typical of the food supply chain can be divided into dumbbellshaped, T, symmetric and mixed four ．dumbbell food supply type of food supply chain is a quasistrict supply is characterized by a shorter supply chain, connecting the main lot located at both ends of the transaction, while the middle of the main chain are few and fewer transactions, showing the dumbbell producers have poor technical conditions, production is low and less variety, it gathered a large number of upstream agricultural producers。the third stage of supply chain integration management phase, the study extends further upstream to the most upstream agricultural enterprises(such as seed suppliers, etc.), the purpose is to extend the tracking and tracing of food quality and safety ofw agricultural products issues in order to quickly and effectively identify and solve article describes the production of different food supply chain logistics system characteristics, and the food supply chain management with the development of food quality and safety are analyzed and causes of supply chain management In recent years, the food supply chain, production and development of people39。s management, food and agricultural industries have followed suit and Supply chain management with a tool to improve their , Zuurbier and other scholars in general, on the basis of the supply chain, first proposed the concept of the food supply chain, and that the food supply chain managemen
