本研究以台灣8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，比較孰優孰劣。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。研究中分別求解CCR效率和A&P效率，此外，亦將CCR效率進一步區分為純粹技術效率(BCC效率)與規模效率，除了效率值比較和衍生的相關討論外，還進行規模報酬分析、虛擬乘數分析、差額變數分析，與敏感度分析，最後則是獲利能力與經營效率之比較。 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。整體來看，投入項目需縮減幅度最大者為員工素質，資本額次之。表示八家生技公司在此期間高素質人力的投入，並無產生相當的營收，原因可能是公司開發的產品未能符合市場的需求，因此，未來在開發新產品方面應加強結合行銷功能，才能充分滿足消費者或客戶的需求。此外，資本額投入過多，造成資源的浪費，也需要公司管理者加強成本的控管，以期達到資源有效分配。從獲利能力與經營效率之比較分析得知，經營效率高的公司大多獲利能力亦較高。 / 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. These DEA models basing on the data of 1996-1999 provide CCR efficiency, and A&P efficiency. Furthermore, CCR efficiency is divided into pure technical efficiency (BCC efficiency) and scale efficiency. Besides the comparison of these efficiencies and the discussion about related content, the present study also performs scale analysis, multiplier analysis, slack analysis, and sensitivity analysis. Finally, the comparison of profitability and operating efficiency is conducted. 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. As a whole, the personnel Ability and Capital should be the first two input item that needs to be reduced. The comparison of profitability and operating efficiency indicates that most efficient companies can have good profitability.
