本文主要研究企業研發活動對企業經營績效之影響，在重視研發的高科技產業，研發投入是否能幫助企業產生未來經濟效益，同時研發活動累積的專利權是否能帶來企業的效益。本研究將進一步探討企業的寬裕資源對於企業研發活動與公司績效之調和效果。本文之研發活動包括研發支出與累積之專利權。
本文之研究對象為2003年至2007年之台灣上市上櫃高科技公司。實證結果發現，企業研發投入與累積專利權數之研發活動將會對企業經營績效產生正面效益，且研發投入具有二年的遞延效果。而寬裕資源對於研發投入活動與公司績效之間將產生負向顯著的調和效果且有一年遞移的影響；然而，寬裕資源對於專利權與公司績效的調和效果則不顯著。本研究的結果支持企業的寬裕資源將調和研發活動與公司績效之關聯性。

This paper mainly investigates relationships between R&D activities and firm performances. In the high-tech industrials, it is worthwhile to study that whether R&D expenditures affect firm future performances and whether accumulated patents also improve firm performances? Furthermore, this paper considers the moderating effect of the slack resources on the relation between R&D activities and firm performances. R&D activities are considered to include R&D expenditures and accumulated patents.
Our sample is targeted at Taiwan listed companies in high-tech industries from 2003 to 2007. The empirical results indicate that R&D expenditures and accumulated patents will have a positive effect on firm performances, which R&D expenditures have lag effect on firm performance for two years. Regarding the moderating effects of firm’s slack resources, firm’s slack resources would decrease the positive relationship between R&D expenditures and firm performance, which the impact have one year lag effect. However, slack resources have no significant moderating effect on the relationship between accumulated patents and firm performances. The finding implies that slack resources would harm the effectiveness of R&D expenditures.
