創新能力是近年產業發展的趨勢，過去文獻常只單用專利數量來衡量研發效率，方法直觀卻無法真實反應專利價值。本研究嘗試利用專利數量及專利價值指數一起衡量廠商研發投入與產出間的效率，研究對象為2005年至2007年間中國規模水準以上廠商，利用其專利總價值指數與該公司所投入的資本要素與勞動要素探討該公司資源錯置的現象。有鑑於中國積極引進外資企業進駐中國，本研究依公司註冊登記類型將公司分為國有企業、民營企業及外資企業三大類，藉以研究中國經濟發展政策對此三類企業研發效率發展的影響。結果顯示，國有企業的研發效率優於民營企業與外資企業。因為政府積極實施產業政策以促進國內研發創新能力，給予國有企業相當多的政策優惠，故國有企業擁有較高的研發生產力；而民營企業因核心技術的不足，多以替國外大廠代工為主要經營模式，研發創新能力較低。中國改革開放後，積極引進外資企業進駐中國，而當時外資企業看中的是中國低廉的勞動成本與廣大的潛在市場，核心研發技術並未引進中國，導致外資企業研發能力在資料區間內呈現最為低落的情形。 / Innovation has become the trend for the industrial development nowadays. In the past, little research can measure the industrial outcome due to inadequate knowledge on patent value index. In this paper, I compute the patent value index based on the surveyed data of the manufacturing firms in China from 2005 to 2007. The misallocation between research output and input is computed as the major result. Based on firm registration data, I divided firms into three categories, state-owned firms, private firms and foreign firms. Our result shows that state-owned firms have higher innovation efficiency than others. The high research efficiency belonging to state-owned firms benefited from many industrial policies and preferential policy implemented by government. Due to the lack of innovation technology characterized by OEM (Original equipment manufacturer) model, private firms record lower research performance. Other than domestic firms, foreign firms simply utilize cheap production inputs and the larger market size as a base for process trade. Innovation activities are only conducted by parent companies. That is why foreign firms’ record lower innovation efficiency in this research.

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.

本研究從DNA定序產業之美國專利侵權訴訟，了解該產業中廠商的訴訟行為與系爭專利之特性。本研究由商用資料庫取得DNA定序產業之美國專利侵權訴訟共100件及其系爭專利共168件，分析訴訟資訊、訴訟主體資訊(原告及被告)和訴訟客體資訊(系爭專利和被控侵權產品)。本研究也由次級資料中歸類各廠商在DNA定序產業鏈中之位置和其各世代產品技術之發展。由訴訟主體資訊可得知在DNA定序產業中，主要發起美國專利侵權訴訟之廠商為中游的儀器平台廠商，被控專利侵權的廠商也多為具有相同商業模式在同樣產業鏈位置上的競爭者。而由訴訟客體資訊中，除了以產品技術結構定位系爭專利之保護標的和技術特徵外，也從專利的被引證數、專利家族大小、所有權移轉次數、國際分類號分佈等指標比較系爭專利和一組同樣專利權人在相同時間間隔內申請的同技術領域之對照組專利，可發現系爭專利和對照組專利相比屬於較有價值的專利。 / The present research analyzes the U.S. patent infringement cases of the DNA sequencing industry to understand the features of patent-in-suit and litigation behaviors in said industry. The present research obtains 100 U.S. patent infringement cases and 168 patent-in-suit from commercial databases. The litigation history, parties in the litigation (plaintiff and defendant), subject matter of the litigation (the patent-in-suit and the infringing products) are analyzed. The present research identifies the position of different corporate entities in the DNA sequencing industry chain and the development of each generations of DNA sequencing technology. By analyzing the parties in the litigation, the present research identifies that most of the plaintiffs are corporate entities developing sequencing instrument, and most of the defendants are competitiors having the same business model with the plaintiffs. By analyzing subject matter of the litigation, the present research identifies the technical features and subject matter of the patent-in-suit. The present research compares the citation, patent family size, number of ownership transfer and IPC distribution between the patent-in-suit and a control group patents of the same technical field within the same time frame. The patent-in-suit is more valuable than the control group patents.

專利和創新是近年產業發展極重要的趨勢，但是在過去對於中國產業的資源錯置相關研究中，卻沒有發現以專利來做為衡量產出的標準。因此本研究蒐集了中國2005到2007年的水準以上製造業廠商資料，並將Mtrends專利檢索平台資料庫中之專利資料加以整合，建構出中國水準以上製造業廠商之美國專利資料的資料庫。並依據文獻所提出之資源錯置模型，以資料庫中之專利資料作為創新研發產出之代表，計算出廠商之效率值與資源錯置的程度。根據廠商之專利數量及專利價值指標兩種衡量方式來討論中國東部沿海三大經濟區，環渤海經濟區、長三角經濟區及珠三角經濟區之效率值及資源錯置問題。研究結果發現珠三角經濟區因開放年代較早，在人力及知識累積下，研發效率值相對較高，資源錯置問題亦相對較不嚴重的，而長三角與環渤海經濟區由於產業多集中於高科技產業，部分廠商之技術尚未成熟，因此在研發效率值的表現上較為落後且資源錯置問題亦相對較為嚴重。 / Innovation and patent applications have become the central issue for the industrial development nowadays. In the past, there’s little research to measure the innovation outputs by patents. Thus, in this paper, I collected the data for the manufacturing firms in China from 2005 to 2007 and combine with the patent data in Mtrends database. Based on my misallocation computation, I use patent as the R&D output and measure the innovation efficiency and the misallocation level. Based on my result, the efficiency is higher in Pearl River Delta Economic Zone due to its earlier development and low in Bohai Bay Economic Zone & Yangtze River Delta Economic Zone because of industrial concentration. Thus, the misallocation is much more severe in Bohai Bay Economic Zone & Yangtze River Delta Economic Zone and is much lighter in Pearl River Delta Economic Zone.
