The aim of this research is to use the Stochastic Frontier Approach to evaluate the management efficiency of the Taiwan Water Corporation’s twelve branches from the year 1997 to 2005. The result of this research can be a reference for the corporation in the hope that it can reach the enterprise’s sustainable management goal. The findings are as follows:
1. The average technical efficiency rate among all the branches can only reach 0.5662. The first two are the twelfth branch (0.9344) and the second branch (0.9059). The rates of the branches which rank from the third to tenth range from 0.6167 to 0.4730. The last two are the tenth branch (0.2916) and the ninth branch (0.3873), so they should make more efforts to achieve a higher rate. In spite of the congenital condition which indicates a greater difficulty, they can still reverse their difficult condition and make more efforts depending on the manager’s wisdom and determination.
2. By comparing the twelve branches according to their geographical location as northern, central, southern, and eastern branches, the findings are: (1) The northern branches, which are the first, the second, the third, and the twelfth, have a wide variation in their technical efficiency. (2) The central branches, which are the fourth, the fifth, and the eleventh, have little difference in their technical efficiency. (3) The southern branches, which are the sixth and the seventh, also don’t have a very big difference in technical efficiency between them. (4) The eastern branches, which are the eighth, the ninth, and the tenth, have an obviously lower technical efficiency rate, and there is also a wide variation among them.
