本研究以臺灣八家生物科技公司為研究對象，探討公司於民國85年到88年之間的經營效率評估。本研究應用資料包絡分析法（data envelopment analysis, DEA）來計算相對效率值。投入要素包括：資本額、研發支出、員工人數，及員工素質共四項；產出項目則為公司營業額一項。 研究結果顯示，效率排名以杏輝表現最佳，其次依序為濟生、葡萄王、永日、永信、生達、中化、五鼎。依年度區分的平均效率值分析，可觀察到的共通現象，皆是從民國85年一路衰退到88年，顯示八家生技公司的營運效率在此期間總體表現不佳。另外，從全體生技公司來看，可以發現公司效率值與獲利能力呈現正相關，即經營效率較好的公司，獲利能力也較好。

Utilizing Data Envelopment Analysis (DEA), this paper examines the relative efficiency of 8 companies over a period of 4 years in Taiwan biotech industry. The study has indicated how to use DEA to identify individual companies that are less efficient than other comparable units of output factors relative to input factors. The research shows that Sinphar Pharm. Corp. is ranked first in efficiency, and then Chi Sheng Chemical Corp., Grape King Corp., Yung Zip Chemical Corp., Yung Shin Pharm. Corp., Standard chemical & Pharm. Corp., China Chemical & Pharm. Corp., and Apex Biotech Corp. in order. Average efficiency of these eight companies declined from 1996 to 1999. The comparison of profitability and operating efficiency indicates that most efficient companies can have good profitability.
