台灣作為一海島型國家，缺乏許多天然的資源以及人力資源…等，所以一直以來台灣都屬於一個技術輸出的國家，尤其是台灣的科技重鎮「新竹科學園區」，幾乎每間公司都是以技術為導向，以2012年研發經費來說，第一名的台積電高達388億元，其次為宏達電的138億元以及聯發科的131億元，到了2014台積電的研發經費支出更高達了616億元，聯發科也高達470.47億元，再再顯示研發經費的支出對於台灣企業價值以及報酬率的重要性。
　　Louis K.C.Chan(2001)將各公司的研發費用支出分成五種程度，再將各個公司的SMB, HML, WML, UMD等數值帶入Fama-French 五因子模型，以判斷該區間的公司是否具有超額報酬，結果顯示R&D對公司是否有超額報酬的確有顯著影響；另外，林美倫(2005)也曾經以台灣資訊電子業公司為樣本，探討研發支出對經營績效及股權評價影響。
　　本研究利用類似的方法來驗證R&D是否對於股價的報酬率有影響，使用的資料為2005年至2014年間，829間電子業上市上櫃公司作為樣本。在模型的部分我們沿用郭啟賢(2013)的員工認股選擇權對公司市場價值的影響之模型，去除員工認股權之變數與年份等虛擬變數，另外加入研究與發展費用支出，使用內外生模型及樣本選擇全探討研究與發展費用支出對股票市場價值之影響。

To be an island country, Taiwan is really poor in natural resources and human resources.So Taiwan has being a technology export countries, especially the Hsinchu Science Park, almost every technology companies are oriented to research and development. In 2012, the most R&D funding company, TSMC is 38.8 billion dallars, followed by HTC, 13.8 billion dollars and MediaTek, 13.1 billion dallars,In 2014, TSMC's R & D expenditures increase to 616 billion dollars, MediaTek also up to 47.047 billion dollars,so R & D expenditure really show its important status in taiwan company.
These are five degree, which can be put into Fama – French Model, in R&D expenditure et al Louis K.C.Chan, It can help manager to judge the measure of excess profit. The results of paper show that the R&D indeed has influenced on excess profit. In addition, the research of Lin. M. L. (2005) shows that R&D has effects on business performance and equity evaluation under Taiwan electronic information industry.
Similarity, this thesis using this method to observe that the effect of R&D with excess profit, 829 company from 2005 to 2014. We also combine the model which provides by Kuo Q. X. (2013), which modify the model proposed by Olhson J.A. (1995).
