Abstract: Agricultural product always has variability of its price at any time, because there is imbalance between supply and demand of agricultural product in Thailand. Thus, Thai government aims to solve this problem by augmenting agricultural cooperative to every province. This research assesse the data set of operational efficiency in agricultural cooperatives by using Super-SBM DEA approach. Super-SBM DEA approach has been integrated two approaches by combining super-efficiency DEA and SBM DEA. This approach is used to measure and compare the operation in term of efficiency and inefficiency of Decision Making Unites (DMUs) under variable return to scale (VRS). The findings of this research show that more than 80 percent all of Thai agricultural cooperatives have operational inefficiency and there are less than 20 percent have operational efficiency. Therefore, the empirical results can differentiate some problems and benchmarks to members and farmers. This research helps government recognize about the efficiency and inefficiency within all agricultural cooperatives in each province. In addition, it also help agricultural cooperatives where have inefficiency organization improve and increase their efficiency.
