摘要 半導體產業在科技開發上投資龐大,技術與生命週期短,屬於技術與資本密集產業,每年為台灣創造高額經濟附加價值與營運價值,在半導體產業與資訊產業價值鏈中位居重要的地位。該產業需要透過專利以保護研發中所取得的技術優勢,因此討論專利相關議題具有重要性。 在公司內財務報表中所展現的訊息是最直接且明白可以展現企業的利益與公司獲利的狀況讓關係人了解,然而在公司報表上不易獲取研發投入或投資的相關紀錄。本研究以專利品質的角度探究其與公司獲利能力的關聯性,期能對公司獲利能力之評斷,有更好的解釋能力。本研究同時利用橫斷面與縱斷面之公司專利與財務資料,以考慮時間因素的影響。 本研究之目的在探討專利品質與公司獲利能力間的關係,利用可同時處理橫斷面與縱斷面資料之方法來檢視專利品質與公司獲利能力的關聯性。以1996至2002年美國半導體產業(SIC 3674)上市公司之資料作為研究樣本,研究結果發現: 1. 各年度企業擁有的專利品質與和獲利能力間具關聯性,並以代表獲利能 力的資產報酬率較為明顯。 2. 平均專利引證數與資產報酬率有顯著的正向關係。 3. 技術強度與資產報酬率的有顯著的負向關係。
Abstract The investment of R&D in semiconductor industry is huge. The life cycle of semiconductor technologies are short, so lots of technological innovation and capital offering are necessary. It contributes primary part of GDP for Taiwan every year. Taiwanese semiconductor industry stands significant position in the world. Patent protection of technology in this industry is strongly recommended, therefore it constructs the important issues for further study. The financial statements of the company should be represented directly and clearly for which the stakeholders could understand the profits of the company. However the records of R&D input or investment are not easier acquired. This research focuses on the relation between patent quality and profitability of the company. This study expects the patent quality will be a good predictor for profitability. Cross-section and time series data of patent citation and financial materials were collected for further analysis. The purpose of this research is to verify the relation between patent quality and profitability of the companies. Cross-section and time-series data are calculated the relation in statistical manner. The data of U.S. semiconductor industry (SIC 3674) between 1996 and 2002 are selected as samples, then the results after analysis are: 1.The relation between the patent quality and profitability of the company were statistically significant. 2.The indicator of cites per patents is positively related to ROA. 3.The indicator of technological strength is negative related to ROA.
