摘要

隨著世界經濟自由化、國際化的發展，公營事業民營化逐漸成為世界各國發展的趨勢。在台灣，中油公司面對油品自由化及民營化政策的挑戰與衝擊。因此，該公司必需了解本身的經營績效與同業間的差異，並設法提升自己的經營績效。對此本研究採用資料包絡分析法（DEA），對26個煉製單位進行經營績效之評估，選擇3個投入項目與7個產出項目，經由Frontier analysis軟體之運算，得到各單位之效率值分析結果。研究結果發現，根據效率分析，得知各單位均有成本浪費現象，應減少投入或增加產出，使各單位達到有效率。而根據規模效率分析，必須同時透過改善投入、產出的比率與調整生產規模，才能達到有效率境界。再篩選出最具相對效率的營業單位作為標竿學習的對象，改善經營方針達到最適規模報酬的效率化經營。根據差額變數分析，建議管理者在投入與產出項數量上應作改善。最後在敏感度分析，顯示中油公司之營業單位經營維持相對的穩定性，且該公司證明整體積極朝向效率化經營邁進。

Privatization has been the significant trend in the recent years in the world. One of the major reasons of privatization is that the private company is more efficient in carrying out economic activities and reducing the public debt. In Taiwan, Chinese Petroleum Corporation (CPC) will face some challenges and pressures of privatization policy and liberalization of oil industry. CPC must understand their differentiation from other competitors, and strive to improve their performance. with application of Data Envelopment Analysis (DEA) approach, this study conducts performance analysis among twenty-six reforming units. The input factors include three items; the output factors are seven items. While interacting the above factors and calculated by Frontier analysis. The findings of this study are as followings: According to the efficiency analysis, finds all units waste their costs, so they should decrease the inputs or increase the productivity to make all units effective. According to the scale efficiency analysis, it must improve the input, the ratio of the output, and adjust the scale of productivity to accomplish the efficiency. In addition, identify the most efficient unit as the model to help others to optimize management strategy and to maximize contribution. According to the slack variables analysis, it suggests managers should improve the numbers of inputs and outputs. According to the sensitivity analysis, it shows that CPC has persisted stability, and proving that the company is moving toward an efficient business.
