生技產業是一個具有豐富無形資產之產業，需透過研發活動創造無形資產，以增進產業價值。因此，生技公司所投入之研發費用係生技產業發展的重要關鍵因素。
本研究旨在探討生技公司所投入之研發費用與其股價報酬間之關係。本研究選取2003至2007年台灣40家上市櫃、興櫃之生技公司及美國76家NASDAQ之生技公司為樣本，將股價報酬作為生技公司績效之衡量變數。本研究運用敘述性統計、Pearson相關係數和複迴歸分析以達到研究之目的。
實證結果顯示，不論台灣或美國之生技公司，其研發費用、研發密度、研發生產力、市場佔有率及員工分紅，皆與股價報酬具有顯著正相關。研究結果亦證實，生技公司研發活動確實會影響股價報酬。此外，本研究亦發現，市場佔有率與研發密度之交乘項，以及員工分紅與研發密度之交乘項，皆與股價報酬呈現顯著相關。 / The biotechnology industry has abundance of intangible assets. It creates intangible assets through research and development activities to add value. Therefore, R&D plays a key role in the development of the biotechnology industry. This research aims to explore whether R&D is associated with stock returns of biotechnology companies in Taiwan and in the United States. The sample consists of 40 Taiwanese and 76 NASDAQ biotechnology companies with data from 2003 to 2007.
The empirical results are as follows. R&D, patents, market shares, and employee bonus are all significantly associated with stock returns both in Taiwan and in the United States, suggesting that R&D activities of biotechnology companies affect their stock returns. In addition, the interaction of market shares and R&D intensity and that of employee bonus and R&D intensity are both significantly associated with stock returns in Taiwan and in the United States.
