ESTABLISHING FOOD TRACEABILITY SYSTEM BASED ON GAME THEORY From the Perspective of Retailers

Retail terminal is a weak link of the whole food supply chain in establishing the food traceability system, and also a key link in realizing traceability food value. This paper firstly analyzes the influence factors of retails adopting food traceability technology, then makes a game model to analyze three situations: non government subsidy; the same government subsidy for adopting the traceability technology and higher subsidy for who adopts the system first. According to the analysis, the conclusion is drawn: it is unrealistic to ask all of retails to adopt food traceability technology; corresponding policy should be made to inspire a part of retails adopting the system first.
