This study analyzes the technical efficiency, which consists of pure technical efficiency and scale efficiency, of Tobacco Production Cooperatives (TPC) in Korea and provides the benchmarking information for each TPC to improve its technical efficiency. Data Envelopment Analysis (DEA) is adopted to calculate technical efficiency and performance data from 19 TPCs in Korea were collected for the study. Salary and operating cost were selected as two input variables and membership fee, the number of members, and the number of administrative unit for each TPC as three output variables. Results show that most TPCs have a room for the improvement of technical efficiency through the adjustment of inputs. Especially, most TPCs are proved to be operated in an increasing return to scale. This implies that scale adjustment can lead to the improvement of technical efficiency. In addition, inefficient TPCs were provided with reference groups to benchmark so that they save inputs and improve the technical efficiency.
