摘要

由於社會環境變遷，固有的績效指標不能適切的反映出組織真實的績效，所以在評自來水公司經營績效時，應改變現有的評估模式以因應環境時代的變遷。本研究運用資料包絡分析法，探討台灣自來水公司12 個管理處之經營績效，研究期間為2010 年至2012 年。根據自來水公司統計年報顯示，2014 年台灣轄區之漏水率高達18.04%，相當一年漏掉1.5 座翡翠水庫總有效蓄水量。然而目前並沒有相關文獻考慮「漏水率」對於自來水公司營運績效的影響，故本研究將首先考慮將漏水率視為非意欲產出變數來探討對自來水公司之影響。本文將採用2 個投入變數分別為用人費用及機械與設備修護費，2 個產出變數中1 個意欲產出分別為營業收入，1 個非意欲產出則為漏水率。實證結果顯示，非意欲產出項「漏水率」，確實對決策單位之經營績產生影響，且經過檢定結果證明為顯著，針對研究分析結果，試擬建議改善意見，以供台灣自來水公司管理階層及主管機關擬訂相關措施之參考。

The inherent performance indicators cannot adequately reflect the true performance of the organization due to the social environment changes. Therefore, the operating performance measurement of water companies should change the existing assessment model in response to environmental changes in the times. In this study, data envelopment analysis was used to investigate the performance of 12 management offices for Taiwan Water Supply Company during 2010-2012. According to the water company's annual report shows that the Taiwan's water leakage rate as high as 18.04% in 2014, quite missing 1.5 emerald reservoir storage capacity in a year. However, there is no relevant literature to consider the effect of ＂leakage rate＂ on the performance of WSC. Therefore, this study will first consider the leakage rate as an undesirable output to explore the impact on WSC. Empirical results show that the undesirable output impact on the performance of the WSC and the results show to be significant. The suggestions can provide the improvement policy to the management and authorities of the Taiwan Water Company.
