| 摘要: | 本論文探討台灣電力公司轄內24個區營業處90年至92年的經營效率。首先藉資料包絡分析法( DEA )效率衡量模式，評估電力公司各區營業處之相對效率值，包括技術效率、純粹技術效率、及規模效率；再由差額變數分析評估各區營業處在各年度對於資源的使用情形，和可能改善的方向與幅度；最後以敏感度分析探討各區營業處之投入產出項中，何者是其關鍵因素，及如何提升效率值。研究結果顯示： 一、桃園、新竹、台中、彰化、嘉義、高雄、屏東、台東、花蓮、澎湖、鳳山、雲林、新營等13個區營業處在90至92年度三年當中，其效率值都為1，屬於相對有效率單位。其共同特性為經營20年以上之區營業處。二、金門、馬祖2個區營業處，其相對效率值不為1，且明顯偏低，屬於相對無效率單位，但轄區為國家軍事要地，有其地域特性。 三、基隆、北市、北北、苗栗、金門等5個區營業處，其效率值自90年至92年度連續三年，每年效率值皆下降，囿於配合政府公共政策加強資本支出執行，致影響效率值。四、北市、北南、北北、北西、台南等區營業處，由其固定資產、裝置變壓器容量之差額變數分析，顯示有投資過多的現象，最明顯的原因是配合捷運的興建與用電需求；還有台南科學園區的成立須相關配電線路之規劃設計施工，雖目前短期投資過多，但以長期而言仍是必須的。
This thesis probes the operation efficiency of 24 branches of Taiwan Power Company (TPC) for the period from 2001 to 2003 to compare the relative efficiency among the branches. The Data Envelopment Analysis, which is capable of dealing with multiple inputs and multiple outputs, was employed. The purposes of this study are: 1. to measure the relative efficiency of 24 branches of TPC in Taiwan, including technical efficiency, pure technical efficiency, and scale efficiency; 2. to evaluate the usage of resources in each branch for each year by the slack variable analysis and to find out the possible direction and coverage of improvement; 3. to probe which key factor is among the input and output items of each branch. The outcomes from the study show: 1.The efficiency measures is 1 for the 13 branches of Taoyuan, Hsinchu, Taichung, Changhua, Chiayi, Kaohsiung, Pingtung, Taitung, Hualien, Penghu, Fengshan, Yunlin, and Hsinying for the three years from 2001 to 2003, meaning that these branches are relatively efficient units.2.The efficiency measures is not 1 and is significantly, low for the 2 branches of Chinmen and Matsu, meaning these branches are relatively inefficient units. But since these two areas are the strategic points of national military bases, they have their own specific characteristics.3.The efficiency measures for the 5 branches of Keelung, Taipei City, north of Taipei City, Miaoli, and Chinmen have been consistently decreasing year by year from 2001 to 2003, which became worse year after year. These branches should be thoroughly reviewed and should aggressively find the right strategy to manage with the circumstances in order to improve the efficiency measures.4.From seeing the slack variables of fixed assets and installed transformer capacity at the branches of Taipei City, south of Taipei City, north of Taipei City, west of Taipei City and Tainan, it is understood that they are over invested. The most obvious reason is to meet the construction of MRT and the demand for electricity and to cope with the design and the construction of relevant transmission lines needed by the establishment of Tainan Science Park. For a long-term point of view, even though they are over invested at present, they are essential in the future. |
