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 published in 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 efficiency for three major ports in Taiwan. The present paper points out the faults or errors found in their article in terms of variable selection, scale efficiency measurement, window analysis, and some erroneous statements in literature reviews. It is hoped that this will make more appropriate and much clearer the DEA applications to port’s performance evaluation.
