本研究應用資料包絡分析法比較國內民用航空公司之營運績效，了解各航空公司相對經營效率表現及其差異所在，並針對無效率部分提出其改善方向與幅度。 研究結果顯示，技術效率方面，近兩年內各航空公司已能有效利用其投入資源；規模效率方面，長榮處於最適生產規模，華航處於規模遞減階段，遠東、立榮、復興處於規模遞增階段；整體效率方面以長榮與復興表現較佳；觀察期間內各家航空公司皆有參考其他公司或是作為被參考評量的依據，顯示彼此間不存在獨特而無法被模仿的特性。本研究整體效率值與獲利能力之間的相關係數並不顯著，即考量多項投入的綜合性整體效率與財務上的獲利能力不存在著必然的關連，表示航空公司雖然年度財報上獲利能力較其他廠商為高，但在考量綜合性指標下，仍存在可改善的空間。 This study employs data envelopment analysis（DEA） to evaluate the performance of five civilian airlines. We try to compare their efficiency. Based on the result, we would like to suggest the way to further improvement. We conclude as following: in the aspect of pure technical efficiency, all of the companies used their resources effectively during last two years. In the aspect of scale efficiency, EVA Airways Corp. is relatively efficient. China Airlines lies in the region of decreasing returns to scale, while the others lie in the region of increasing returns to scale. In the aspect of global technical efficiency, EVA Airways Corp. and TransAsia Airways Corp. performed comparatively better. During the time periods of observations, each company had others in its reference set or was compared with others. This comparative study shows there is no unique attribute that can not be learned among companies. The correlation coefficient between total efficiency and profitability is not significant. It reveals that some aspects still need to be improved according to comprehensive index even though profitability of the company is higher than others on the annual report.
