An Analysis of the Efficiency of Agricultural Business Corporations Using the DEA Model

The purpose of this study is to estimate efficiency of agricultural business corporations using Data Envelopment Analysis and analyze the characteristic of efficient corporations using Tobit model. The technical efficiency, pure technical efficiency, and scale efficiency measure of the corporations is 0.78, 0.84, 0.93 respectively. Among the 587 agricultural business corporations, the number of efficient corporations whose efficiency value was 1 was ① 21(3.6%) in the technical efficiency; ② 92(15.7%) in the pure technical efficiency; and ③ 39(6.6%) in scale efficiency. Among the 587 agricultural business corporations, the number of Increasing Returns to Scale (IRS)-type corporations was analyzed to be 142(24.2%). The number of Constant Returns to Scale (CRS)-type corporations was 42(7.2%), and that of Decreasing Returns to Scale (DRS)-type corporations was 403(68.7%). Since an increase in output is lower than an increase in input in DRS, an decrease in input factors such as new investments is required. This study shows that the size of asset and capital, the number of labor are important variable for efficient agricultural business corporations.
