本文以1991-2001年期間工研院執行的372個年度科專計畫爲研究對象，蒐集其專利資料並輔以問卷，運用計量方法來探討其研發行爲。本文的主要實證結果爲：（1)以國內專利數爲被解釋變數的模型所得的R&D支出彈性值爲 0.354。然而若以美國專利數爲被解釋變數的模型所得的R&D支出彈性值會提高為0.555，此與Hausman, Hall and Griliches  (1984) 的研究所得之0.49相當接近。(2)工研院科專計畫的專利品質呈逐年上升趨勢，是一可喜現象。（3)經過品質調整的研發人力對研發產出有正向的影響。而科專計畫執行年期越長者，其研發成效越顯著，其中尤以11~12年者爲最。電子類科專計畫之技轉案例屬於製程相關技術之比重增加時，對專利表現有正向影響；然而化工材料類和機械自動化類科專計畫則剛好相反；（4）參與計畫廠商規模和區位對計畫執行成效的影響端視產業別而定。

This paper evaluates the R&D production behaviors of 372 public science & technology projects conducted by ITRI during 1991-2001 using an econometric model. Our major findings are: (1) On average, the elas­ticity of R & D expenditures to domestic patents is 0.354, while it is 0.555 for US-granted patents, which is close to the results of Hausman, Hall and Griliches (1984); (2) Our evidence shows that the patent quality of ITRI S & T projects improved over time; (3) The effects of quality­-adjusted R & D personnel and project length on patents are positive; (4) The influence of the percentage of process innovation, size and location of participating firms on patent performance varied among different fields'S & T projects.
