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.

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.
