電力事業是影響經濟最重要產業之一,50年來,台灣的電力均由台電公司所獨家供應,台電公司能否充裕供應高品質的電源攸關台灣經濟與產業興衰,此外,在21世紀,全球經濟型態邁向國際化、自由化的趨勢下,電業自由化亦成為現階段政策發展重心,故此時探討台電公司的經營效率情形及面對民營化衝擊下,提出改善經營效率的策略,實為當務之急。本研究決定採用DEA模式來衡量台電公司及各區營業處近年來的經營績效,經分析後,得到以下結論:一.時間數列分析 (一)台電公司技術效率偏低,最主要為規模的缺乏效率。 (二)台電公司在資本與人員投入上已有過剩現象,今後在資本投資與人員配置方面更應審慎。 (三)若不考慮規模不適的因素,依BCC所衡量之純粹技術效率=1的DMU有14個,即27年的資料在BCC的模式下有14年達到最佳效率。 (四)消費的明顯尖、離峰性及建廠時間較長,必須事先預測未來的負載需求,而預先開發電源等特性,容易造成人員的配置不當,且備用容量的成本又高,此均會造成技術效率的不佳,及無法處於最適規模狀態。二.台電公司所屬各區營業處經營效率之分析: (一)各區營業處的技術效率平均值=0.974,純粹技術效率平均值=0.992,規模效率平均值=0.981,都在0.950以上,績效不差。 (二)根據Norman and Stocker(1991)說法,將所有DMU依整體效率值強度予以分類為強勢效率單位、邊緣效率單位、邊緣非效率單位、明顯非效率單位4個集合,分類後可清楚的看出各區營業處的經營績效及84、85、86 三年來績效變化情形。 (三)在本研究中顯示整体效率值與地域間及業務量大小並沒有絕對相關,例如澎湖區處、台東區處84年度均被評選為強勢效率單位。 (四)三年來各區營業處效率值有下降的趨勢。 (五)在本研究中,顯示各區營業處各自擁有經營上的優勢與劣勢之投入、產出項目。
Electric industry can be one of a few most crucial industries to a nation. It is importance to a nation''s economy and the people''s living. In recent five decades, Taiwan Power Company (TPC) has been the sole electric utility in Taiwan. How the Company operates closely reflect to how the people and business be served. Since global trend internationalization and libera-lization, it is even more urgent for TPC to bring up its impro-vement strategy coping with situation related to business ope-rational inefficiency.Aiming at the goals mentioned above, this study decided to apply DEA model to evaluate the operational efficiency of TPC as a whole and its 22 District Officces. The findings through this study are listed as follows: 1.The results of time series analysis(1) The major reason of low technical efficiency of TPC is the lack of scale efficiency.(2)The input of capital and manpower of TPC has already been excessive, therefore, the investment of capital and the allocation of manpower must be careful.(3)If we don''t consider the factor of improper scale, According that the measure by BBC model, there are 14 DMU bring about the pure technical efficiency =1, in other words, there are 14 years arrive at optimum efficiency among the data of 27 years by BBC model.(4)Because of the clear distinction between peak and off-peak consumption characteristics and taking much time for building a power plant, we need foresee the future demand loading and develop some sources of electric power in advance. According to above reason, it is easy to make man power misallocation and have a high cost capacity margin. Hence, it causes a lower technical efficiency and the situation not to be in a optimum scale. 2.The results of efficiency analysis in the 22 district offices of TPC(1) The average value of technical efficiency of all district office is 0.974, the average value of pure technical efficiency is 0.992, the average value of scale efficiency is 0.981, therefore, the whole values are above 0.950 ,the performance is not quite bad.(2) According to the sense of Norman and Stocker (1991),all the DMU can be classified into four ranking criteria on the basis of the strength of overall efficiency: the robustly efficient unit, the marginal efficient units, the marginal inefficient units, the distinctly inefficient units. After the classification, we can clearly see the performance efficiencies and their some changes in district offices during the 1995 to 1997.(3) In this study, it appears no absolute relation between overall efficiency, either in the operational place or the amount of task . e.g. Penghu and Taitung district offices are still evaluated as the robustly efficient units based on the above ranking criteria .(4) Comparing to the performance value at 1995 to 1997, these values of all district offices have a descending trend in the recent 3 years.(5) Finally, the results of this study depict the district offices which have its own strength or weakness of input and out.
