應用DEA/AR模式評估港埠經營效率之研究－－以基隆、臺中及高雄三港為例：評論意見

APPLYING THE DEA/AR MODEL TO EVALUATION OF THE OPERATIONAL EFFICIENCY OF PORTS－ AN EMPIRICAL STUDY OF KEELUNG, TAICHUNG, AND KAOHSIUNG PORTS: A COMMENT

應用資料包絡分析法於評估廠商之績效時，有若干細節應特別留意，本文對於林彬等人 （2006） 發表於本刊第35 卷第4 期頁391-414 的文章提供若干評論意見，按該文中作者應用資料包絡分析法與限定權重範圍模式以評估臺灣三個主要港埠的經營效率，本文指出該文在變數選取、規模效率衡量、視窗分析及文獻回顧等方面的若干缺失，期盼能使資料包絡分析法之應用更為洽當及更為清晰。

This paper provides critical remarks and remedies to a recent article publishedin this Journal, volume 35, number 4, page 391-414, by Lin, Yu and Yang(2006). In their article, the authors employed the data envelopment analysis(DEA) and assurance region (AR) approaches to investigate the operational efficiencyfor three major ports in Taiwan. The present paper points out the faultsor errors found in their article in terms of variable selection, scale efficiencymeasurement, window analysis, and some erroneous statements in literature reviews.It is hoped that this will make more appropriate and much clearer theDEA applications to port’s performance evaluation.
