The establishment of cooperative rice mills is intended to help members of the cooperative, which as a source of paddy and provide fair prices to farmers, but the operations of cooperative rice mills are limited in the quantity that is not enough. It can be said that rice mills could not reached maximum production capacity because of insufficient raw materials. This study had objective 1) to study characteristics of rice mills 2) to study costs of milling process 3) to study efficiency in milling and 4) to study managerial efficiency of the agricultural cooperatives’ rice mills in the northern of Thailand. The data were collected from 15 agricultural cooperatives’ rice mills in northern Thailand. This study applied Data Envelopment Analysis (DEA) and Input-Oriented model under variable return to scale condition to estimated milling and managerial efficiency. The results found that the most cooperative rice mills were medium rice mill size. The agricultural cooperatives’ rice mills were milling according to customer order. The most of the products were sold to cooperative members and local market, some cooperative rice mill produced rice products for direct sale company with their own brands. In the milling process, the average cost was 18,036 baht per ton. The average revenue was 18,243 baht per ton and net revenue was 207 baht per ton. The efficiency of milling found that the average efficiency score was high level but the inefficiency mills can be improve by developing process in milling to increased output 6 percent and reduced inputs such as employees and depreciation. The most agricultural cooperatives’ rice mills also had the other businesses were agricultural products collection and agricultural processing. The managerial efficiency of rice mills revealed that average efficiency score was high level and inefficiency mills can be improve by increased revenue was average 3.37 percent and should be decreased operating cost. The results showed that the most of cooperative rice mills still have opportunity to improve their productivity.
