To anticipate and control the negative effects of the implementation of FTZ policy, It is necessary to study about rice marketing trade system in the Riau Islands region. The study was conducted to identify patterns of supply and marketing of food (rice) and analyze the marketing margin and marketing efficiency as well as the factors that influence it. The study was conducted through desk study and field surveys.
