本研究之問題在於探討：是否研發投入與專利產出較高的科技廠商其經營績效也會較佳？本研究蒐集台灣IC設計、IC製造、IC封裝與IC測試所有上市上櫃廠商在2001-2007年的追蹤資料，應用Färe, Grosskopf, Lindgren, & Roos (FGLR, 1989)的實證模型來估算這四個產業的Malmquist指數，以評估台灣IC廠商的生產效率。接著，本研究估算這四個產業的投入資本報酬率(ROIC)以分析其獲利能力。最後，本研究以整合Malmquist指數及資本報酬率(ROIC)的經營績效矩陣，來分析這四個產業在經營績效上的差異性。本研究有以下結論：（一）IC設計產業研發密度與人均專利產出高於其他三個產業，其獲利能力表現也最佳，IC製造產業在生產效率與獲利能力的平均表現次之，IC測試產業在生產效率的表現雖位居第三名，但其獲利能力均為殿後；（二）研發投入越多的產業，其生產效率與獲利能力也會較佳，產業獲利能力受研發投入的影響高於生產效率，但不見得有助於產業整體經營績效。

This study aims to investigate if the operation performance of technology firm, with higher R＆D input and patent output, would be better? First of all, this study employs panel data, including IC design, IC manufacturing, IC assembling, and IC testing industries, from 2001 to 2007 and develops empirical models, proposed by Färe, Grosskopf, Lindgren, ＆ Roos (FGLR, 1989), to calculate the Malmquist index for evaluating the productivity of IC industry. In addition, the rates for Return-On-Invested-Capital (ROIC) are showed for evaluating the profitability. Finally, this study proposes a performance-matrix, integrated by Malmquist index and ROIC rate, to value changes of both productivity and profitability of Taiwan’s IC firms. The empirical results show that, firstly, the R＆D density and patent output of IC design industry are in the first place. The profitability of IC design industry is also the best. The productivity and profitability of IC manufacturing are in the second place. The productivity of IC testing is in the third place but its profitability is in the last place. Secondly, the productivity and profitability of industry are getting better while it takes more R＆D input. The influence of R＆D input on industrial profitability is higher than industrial productivity, but it is not necessarily contributive to industrial operation performance.
