本文章所探討的研究對象是於台灣證券交易所上市的電子廠商，並採用自2000年至2008年為觀察年間。使用「台灣經濟新報(TEJ)」的財務統計資料，連結廠商於「美國專利暨商標局(USPTO)」申請核准的專利權，建構相關的資料，以分析台灣電子廠商在R&D及授權費用對於自身技術及創新能力的影響。
本研究的實證模型主要是參考Johnson D. K. N. (2002) 加以修改，使用Fixed effect與Random effect分別進行估計，探討不同變數對於廠商技術提升與創新能力的影響。而經由實證結果顯示，隨著廠商在R&D費用投入及授權費用的增加，廠商的科學創新能力隨之上升，同時也提高專利取得的機率。除此之外，本研究於實證模型中也加入了R&D的外溢、廠商大小、廠商資本、R&D的落後期及不同類別廠商的虛擬變數，以觀察其它因素對於廠商在技術提昇及創新能力上的影響。

This study uses the patents acquired from 2000 to 2008 in the Taiwan Stock Exchange-listed company as the raw data. The patents are approved by "United States Patent & Trademark Office (USPTO)" standard. We combine the "Taiwan Economic Journal (TEJ)" financial statistical information with "United States Patent & Trademark Office (USPTO)" to construct the data base that employed in this research. The purpose of this study is to analyze the effect of electronics manufacturers’ R&D and licensing expenses on technology and innovation capability in Taiwan.
The empirical model is based mainly on Johnson D. K. N. (2002) with modification that meets the needs of this article. We estimate the data under Random effect and Fixed effect to examine the effects of different variables on the firms’ improving technology and innovation ability. The empirical analysis shows that firms’ increasing investment in R&D expenditure and licensing fees not only leads to increasing technology and innovation, but also bring a positive influence on patent application. In addition, this study also use several variables such as the R&D spillovers, firm size, firms capital, R&D lag and the different types of firms’ dummy variables to observe their impact on the upgrade of technology skills and innovative ability in Taiwan.
