現今的知識經濟時代，企業所面臨的競爭環境正歷經重大的改變，同時技術更新速度也日益加快，企業皆期望能在攫取消費者青睞之際一併擺脫同業競爭對手的糾纏，研發策略的制定應建構在策略性資源上，以求在激烈的競爭局勢中拓展自身競爭優勢。因此，本研究將以研發策略為中心，以過去相關研究為基礎，採用資源基礎理論之觀點建立一整合性架構，深入探討新的研發策略類型，更進一步探討何種研發策略類型，在資源的投入與競爭優勢的取得，具有正增強的效果。

　　本研究根據研究目的與研究假設，針對高科技產業的研發部門進行問卷的發放，並且使用因素分析、相關分析、迴歸分析及差異性分析等資料分析方法，將問卷結果加以分析、歸納與解釋經由迴歸分析驗證研究假設，並得到以下結論：
一、本研究結合組織之核心能力以及研發流量整合性的探討其對企業研發策略之影響，以歸結出核心資源中的「無形資產」為影響企業研發策略的因素。
二、經實證結果發現外溢效果中的「利潤外溢」對於企業達成競爭優勢有正向且顯著的影響。
三、經實證結果發現，核心資源中的「無形資產」主要影響知識流動中的「知識擴散度」，而核心資源中的「組織能力」則主要影響知識流動中的「知識成長度」，除此之外，「知識成長度」對於研發存量有顯著的影響，而「知識擴散度」則對於研發存量及外溢效果有顯著的影響，更進一步證實，「知識擴散度」有助於研發策略的發展，並達成競爭優勢。
四、本研究實證探討可知「研發費用」及「研發人力」對於研發存量、外溢效果皆不存在任何顯著關係，因為重點不在於資金及人力的投入，而在於資金投入後，能否產生更多的技術知識，進而提昇外界技術資訊的認知能力與應用能力，以及人力投入後的員工教育訓練，因為組織擁有優質的人才，才有益於認知與吸收外部資訊。
五、本研究實證結果給予企業界制定研發策略時的一個新方向，一個有助企業達成競爭優勢的研發策略類型－「高研發存量」及「高外溢效果（利潤外溢）」。

　In recent knowledge economy era, there is considerable change in the competitive environment firms face as well as rapidly increasing development of technology. Firms not only want to catch customers’ attention, but also to get rid of competitors’ chasing. To enhance their own competitive advantage in highly competing situation, the R&D strategy should be developed and decide on the basis of strategic resources. Thus, basing upon previous related studies, this research focuses on R&D strategies and employs resource-base theory to build an integrated framework to investigate new emerging types of R&D strategies. Additionally, we further explore what type of R&D strategies will have positive impact on investing resources and gaining advantages.

　According to research purposes and hypotheses, this research use Factor Analysis and Reliability Analysis, Correlation analysis, Regression analysis and ANOVA to analyze, summarize, explain the data derived from questionnaires, and then test hypotheses by regression models. Finally, we reach/obtain conclusions as follows:
1.These research attempts to integrative explore how the combination of organizational core competences and R&D flow has effect on the R&D strategies to, and the result is that intangible assets are the key affecting factor.
2.According to the empirical analysis results, we found that rent spillover has the significantly positive effect on competitive advantage.
3.Our empirical findings confirm that the intangible assets can affect the diffusion of knowledge, and the organization capacity affect the growth of knowledge. Additionally, the growth of knowledge has the positive effect on R&D store, and the diffusion of knowledge positively affect R&D store as well as spillover effect. Hence, it also provides evidences that the diffusion of knowledge contributes to developing R&D strategies and, so as to achieve the competitive advantages.
4.The empirical analysis also reveals that R&D expenditure and R&D human resource have no significant association with the R&D store and spillover effect. Therefore, the key point is that firms should focus on the technology and knowledge generating from the input of capital and the human resources, rather than how much capital and the human resources they must invest.
5.Finally, we pave the way for firm to develop R&D strategies, and offers an ideal type of R&D strategies: high R&D store and high spillover effect.
