水是人類維持生命不可缺少的基本要素，在台灣，自來水事業是一個典型的自然獨占市場，本研究以台灣省自來水公司為探討對象，運用隨機邊界生產函數模型，評估該公司所屬十二個區管理處八十六年度至九十四年度經營效率的高低，期將研究結果提供經營者在營運上之參考，以達企業永續經營之目的。實證結果如下：
1.各區管理處平均技術效率僅0.5662，前二名為第十二區（0.9344）、二區（0.9059）管理處，技術效率值高的主要原因為供水範圍內用戶密集、工廠林立用水量大，平均售水單價較高，同時每平方公里用戶數多、抄見率高、用人費用占總成本比率低等因素。排名第三到十的區處，其值介於0.6167~0.4730間，最後一、二名為第十區（0.2916）、九區（0.3873）管理處，可努力的空間很大。
2.將十二個區管理處所在地理位置細分為北、中、南、東四個區域比較，結果發現：（1）北部區域一區、二區、三區、十二區區管理處平均技術效率差異大，在於用戶數密集程度、平均售水單價及抄見率高低，影響技術效率值。（2）中部區域四區、五區、十一區管理處平均技術效率在伯仲之間。（3）南部區域六區、七區管理處平均技術效率差異不大。（4）東部區域八區、九區、十區管理處平均技術效率值明顯偏低，且差異甚大，係因服務面積廣，用戶數少且分散，而每單位給水收入所投入之固定資產偏高，及抄見率逐年下滑，均造成效率低落。

Water is the most essential element for maintaining humans’ lives. In Taiwan, the water industry is a typical monopolistic market. 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.
