According to research by the Institute of Transportation, the operation of the Taiwan High Speed Rail(HSR) has had a significant impact on the national expressway transport industry since it opened in 2007. To explore the operational efficiency of the routes that have offered national expressway transport service in recent years, this research has applied Data Envelopment Analysis(DEA) and analyzed two-year data from ten transport service routes, including five national expressways, three provincial highways, and two service routes in Yilan County. By means of distinguishing the input-output discriminating power, it was concluded that estimating "seat-kilometer", "salaries of driving and maintenance staff", and "cost of materials caused by driving and maintenance" as the input measures and using "incomes" and "passenger-kilometers" as the output measures served as the best method to evaluate the efficiency of the ten routes. The analysis result shows that the average technical efficiency of the five national expressway routes is better than those of the provincial highways and the routes in Yilan County. The top three efficient routes of the ten all serve on the national expressway, including Taichung - Kaohsiung, Taipei - Taichung, whose two terminals are similar to the HSR’s but more convenient than the HSR for connection to other places, and the Keelung - Hsinchu, one serves more northerly locations than the HSR does. Nevertheless, the Taipei - Kaohsiung expressway route has not been so efficient as although its terminals are similar to the HSR’s it is not superior to the HSR in transport connections, furthermore, its one-way service is over twice the time spent on the HSR. Additionally, on average, the routes served by the provincial highways and Yilan County roads are even less efficient. By adopting CCR and BCC models the reason for the inadequacies of those provincial highways can be found to be pure technical inefficiencies while the cause of those in Yilan County is due to scale inefficiency. In addition to building up an evaluation model and exploring the efficiency of every route, this research also evaluated the causes for inefficiency and provided directions for improvement. However, subject to data limitations, there are still incomplete parts that would need to be adapted.論文口試委員審定書 致謝 I 摘要 II ABSTRACT III 目錄 V 圖目錄 VII 表目錄 VIII 第一章 緒論 1 第一節 研究動機與背景 1 第二節 研究對象 5 第三節 研究目的 7 第四節 研究流程圖 8 第二章 文獻回顧 9 第一節 運輸產業績效的定義 9 第二節 公路汽車客運業之績效研究的目的與方法 10 第三節 資料包絡分析 12 一. 理論起源與模式發展 12 二. 特性與限制 13 三. 以資料包絡法研究公路汽車客運業之績效曾採用的指標 14 第三章 研究設計 16 第一節 投入與產出導向模式之選擇 16 第二節 資料包絡法之分析流程 16 第三節 變數組合之挑選與其解釋力的確認 18 第四節 資料包絡法數學模型 18 第五節 效率來源與規模報酬傾向 21 第六節 參考群體與效率之改進 22 第四章 路線分析 23 第一節 決策單位之挑選 23 第二節 投入與產出變數之挑選 24 第三節 效率比較與規模報酬 29 一. 決策單位之效率表現 31 二. 不同性質之路線平均效率表現 34 三. 不同年度之路線平均效率表現 36 第四節 參考單位與差額變數 37 第五節 各路線之整體效率分類 40 第五章 結論與建議 42 第一節 結論 42 第二節 研究限制 44 第三節 未來研究建議 45 參考文獻 471153944 bytesapplication/pdf論文使用權限：不同意授權運營效率評估資料包絡法國道客運thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/262761/1/ntu-103-R01741025-1.pdf
