創新無論在經濟成長或是企業競爭中，都扮演非常重要的角色，其中專利權又是保護創新的重要關鍵，但基於專利價值分佈呈離散且偏態的特性，企業在從事研發活動時，必須重視專利品質，以避免專利與技術貿易收支之矛盾情形。過去在專利品質的研究上，被引證次數是最有效的衡量指標，但目前作法卻僅考慮直接被引證次數，而忽略間接被引證次數，此作法造成三個問題：忽略了間接引證資料的攸關性、未考慮各個被引證次數的品質差異、未考慮引證專利的品質差異。因此，本研究以實證研究方法，探討間接被引證次數對企業價值的影響，進而評估間接引證資料於專利品質評估的應用。 本研究以在美積極從事專利活動的美國公開上市企業為樣本，期間為1980年至2002年，以二因子固定效果模型，觀察化學、電腦與通訊、電子與電機產業的創新活動對企業價值的影響。本研究有兩點重要發現：一、研發強度與專利產出效率與企業價值相關性低，甚至呈負向相關，而兼顧量與質的專利指標則與其呈現正向相關，表示研發必須值、量並重；二、間接被引證次數具有價值攸關性，且其影響力會逐層遞減，此結論不僅提供未來相關研究的重要基礎與新的研究方向，更表示在從事專利分析或專利指標設計時，需將間接引證資料納入考量。 / Innovation always plays an important role in both economic development and corporate competition, therefore patents that protect innovation are key. But because patent values are highly dispersed and skewed, corporations must focus on quality and not merely on quantity in R&D management to prevent a technology trade deficit while increasing the quantity of patents granted. Much literature has found that the number of citations received is a good proxy for patent quality. But most people only consider direct citations and ignore indirect citations in their research and practices. These people ignore three important facts: the value relevance of indirect citations, the weight difference of each citation count, and the quality dispersion of citing patents. As a result, this study utilizes empirical methods to discuss the influence of the number of indirect citations received on corporate market value and then assesses the relevance of indirect citation in patent indicators. The samples used in this study are 1,624 U.S. listed firms that have been active in applying for for patents in three areas: chemical, computer and communication, and electric and electronics between the years 1980 and 2002. This study uses two-way fixed effect model to evaluate the influence of innovation activities on corporate value. The first conclusion suggests that patent indicators based on quantity and quality has positive correlation with corporate value while R&D intensity and R&D efficiency based on patent quantity both have low correlation and sometimes even a negative correlation with corporate value. This implies that corporations must develop a R&D strategy that focus both on quantity and quality at the same time. The second conclusion confirms the value relevance of the number of indirect citations received and finds the progressively declining influence of ascending citation orders. This study not only offers an important basis and brings up new issues for future related research but also confirms that taking indirect citation data into consideration is necessary.

顯示器在日常生活中應用廣泛，未來市場發展朝向大尺寸、畫面精緻度兩方面發展，在畫面精緻度方面，目前主要發展技術有二：OLED及量子點，由於OLED尚有產品壽命短、畫面殘影、成本較高等缺點待克服，且在製程上與現今主流LCD相差甚多，因此本研究針對另一可能發展之技術－量子點進行研究，了解產業現況、技術發展趨勢，並給予台灣相關企業建議。 本研究蒐集與專利品質相關的專利量化指標－專利家族規模、申請專利範圍項數、引用專利數、被引用次數及專利年齡，並利用主成分分析法計算專利品質方程式，以針對研究範圍內的專利進行品質排序，並且蒐集專利權人相關市場及專利活動資訊。在專利分析部分將產業區分上、中、下游三區位進行分析，每一產業區位包含重點專利、重要專利權人分析，在中游部分，另進行專利權人研發專利佈局分析，以專利活動程度與專利品質兩軸向衡量市場競爭者之地位。 研究結論首先將總結如何以專利量化指標衡量專利品質，接者以專利分析結果說明量子點顯示技術整體產業發展現況，並歸納台灣企業未來策略。近年投入研究之企業、申請專利數量漸增，但目前尚無企業在此技術領域處於領導者之地位，上游企業的研發方向多是改善LED背光源各波長強度不均的問題，可加強與量子點研發製造商的合作；中游企業需注意韓國廠商大量申請專利所帶來的效果及部分專利權人專利活動程度低，然而握有高品質專利，對其他企業可能造成威脅；下游企業則須思考如何以其他關鍵技術搭配量子點顯示器，研發符合消費者需求之產品。研究最後，針對以專利量化指標進行專利品質分析的過程進行檢討，給予未來研究建議。 / Nowadays displays have wide applications in our daily life, people are looking forward to large size displays and high image performance displays. OLEDs and Quantum dots are the most important technologies which may enhance the image performance. However, OLEDs have some key disadvantages, including the high price, the motion blur and the short lifespan. Therefore, this study focused on Quantum dots. By looking into the industry and realizing the development of Quantum dots, this study gave advice to related companies in Taiwan. To measure the value of patents, we collected five quantifiable indicators of each patent－the patent age, the size of patent family, the amount of claims, forward and backward citations. Then, we calculated the weight of each indicators by Principal Component Analysis（PCA）. As the result, the value of patents were estimated. In the chapter of patent analysis, we classified patents and patentees to the upper, middle and lower stream, each category included the analysis of important patents and patentees. In the middle stream, we also analyzed the patent portfolio, according to two axis－the patent activity and the patent quality proposed by Ernst in 1998. In sum, this study found that companies invested and researched in the industry increasingly; however, there was no company at the leader position. In the upper stream, companies were improving the intensity of different wavelengths in the backlight, cooperating with quantum dot suppliers could be a good strategy for those companies. In the middle stream, Taiwan companies should pay attention on competitors locating in the high patent activity and the low patent activity but high patent quality. In the lower stream, products disposed quantum dots should also fit in needs of customers. Finally, this study reviewed the analysis of patent quantifiable indicators and gave suggestions for the future research.
