根據民國88至90年教育部統計處出版的資料，本文首先利用資料包絡分析法評估個別國立大學之技術效率；然後，以Tobit截斷迴歸模型探討可能造成國立大學技術效率差異之因素。技術效率評估結果顯示，在不同投入產出組合下，國立大學整體的技術效率平均值介於115.30﹪與122.17﹪之間，並且，規模效率平均值大於1，代表：台灣國立大學在產出上仍存在改善空間；且造成其不效率之原因，主要歸咎於純技術無效率及規模無效率。Tobit截斷迴歸實證結果顯示，大學部學生比例與技術效率之關係為負向，競爭程度的提高可提昇國立大學的經營效率，師範與科技類大學的技術效率低於其他大學。 關鍵詞：技術效率、資料包絡分析法、Tobit截斷迴歸方法 JEL Classification：L83、M11、M21

近年來台灣筆記型電腦產業，在廠商延續過去多年的擴張競爭力下，在產值與產量上皆有大幅度的成長。但也由於低價風潮的盛行與全球景氣蕭條，使得該產業的獲利大不如從前；加重了國內廠商經營的困境與競爭程度，此時惟有掌握經營績效之廠商才可維持競爭優勢；以因應高度的競爭環境。在此同時，南韓已從金融風暴的創傷下逐漸走出；並挾帶著全球最大TFT-LCD及DRAM的量產國，並從輕薄型機種切入市場以及加入代工訂單的爭奪戰中。而日本擁有全球頂尖的設計創新能力，筆記型電腦自製率仍偏高。因此日、韓一直是台灣的主要競爭對手。 首先藉由資料包絡分析法評估我國筆記型電腦商於2000年至2003年間的經營效率；並為彌補DEA無法做跨時期的分析，應用Malmquist生產力指數予以分析；接著用Tobit迴歸分析來探討廠商無效率的原因。得到以下的結論： (1)於這4年間的技術效率平均值呈現年年上揚的情況，且規模較大的廠商不意謂著經營績效會較好。(2)這4年間的生產力亦是逐年提昇，主要是技術變動所致。(3)在Tobit迴歸分析中，存貨週轉率、總資產週轉率與品牌對效率有正向影響；而TCRI有負向影響。 接著對台、日、韓進行比較分析，得到以下結論：(1)台、日、韓三國的經營績效，以日本最優、韓其次、台最差；但日、韓的整體效率值逐年下滑，而台灣有逐漸改善的趨勢。(2)三國於2000~2001年間生產力皆下降，這與全球景氣蕭條及九一一事件有相當的關聯；2001~2002間由於無線上網的新技術致使消費性機種熱賣，因此於該期間，生產力呈提昇現象。(3)由Tobit迴歸分析得知存貨週轉率、總資產週轉率與經營年限對效率值有正向影響。 / In the recent years, Taiwanese Notebook manufacturers last the past years, extensions to make productive values and production grow up enormously. Due to the low price trend and global business trend stagnancy, resulting to profitability be not as good as the before for this industry. It deepens to operate and complete hard for the domestic manufacturers. At the same time, only the manufacturers that seizing operating the performance will maintain completing advantage to deal with highly completing enviornment. At the same time, South Korea has already got over from the shadow of 1998 crisis; and took along the most global productive country of TFT-LCD and DRAM; going into the market of frivolous type and join a battle of OEM/ODM orders. Japan owns global excellent design and capability of innovation and self-made ratio is still high. Therefore, Japan and South Korea are constantly Taiwanese major rivals. Firstly, it estimates how Taiwan Note Book manufacturers operate in 2000 to 2003 by Data Envelopment Analysis;In order to making up DEA not undertaking time-series analysis, using Malmquist Productivity Index to analyze; utilizing Tobit regression to analyze the factors that producers operate inefficiently. It gets the following conclusions:(1) In these four years, average technical efficiency is taken on rising year by year, and large scale producers do not imply better operating efficiency. (2) In these four years, the productivity is also rised year by year. This is due to technical change. (3) In Tobit regression analysis, there is a positive influence that inventory turnover, total asset turnover and brand affect efficiency; there is a negative influence that TCRI affects efficiency. This study gets the following conclusions;(1) For Taiwanese, Japanese and South Korea’ operating performance, Japan is the excellent, South Korea is the next, Taiwan is the worst. But Japanese and South Korea’ overall efficiency is worse year by year; Taiwan operating performance is gradually improved. (2) These three countries’ productivity decline from 2000 to 2001. It is concerned with global economic recession and 911 incident. The productivity is raised from 2001 to 2002. It results from WLAN type to sell briskly. Turnover ratio of inventory and turnover ratio of total asset tighter operating years all have a positive influence on efficiency.

台灣產業的發展一向與國際市場的脈動相連，光電產業也不例外，近幾年來在國際的夾擊之下依然發展得極為出色，與其他部分高科技產業共同支撐起台灣科技產業的命脈。所以本研究藉著資料包絡分析法 (data envelopment analysis, DEA) 的應用，透過計算整體技術效率、純粹技術效率、規模效率與 Malmquist 生產力指數，具體衡量出各廠商的生產效率值與跨期變化情形以供廠商參考。另外將光電產業依產品特性分成幾個次產業，為各次產業提出客觀的經營建議。最後由 Tobit 迴歸分析影響效率的重要因素，提供提升效率的參考，希望能對我國的光電產業有所幫助，而繼續為台灣科技產業的成長努力。 本研究以國內 30 家光電產業廠商於 2000 年至 2003 年之資料為研究範圍，選取的投入變數為：員工人數、固定資產、營業成本與營業費用四項，產出變數為營業收入淨額與稅前淨利。另外迴歸分析中使用的解釋變數為董監員工紅利率、存貨週轉率、負債比率、研發費用率、 TCRI 信用評等與董監持股比率。 研究結果顯示，整個光電產業整體無效率的原因較多是技術無效率導致，小部份是規模無效率造成的；而就每個次產業而言，以其四年平均值來看亦是受技術無效率影響較多。而在 Malmquist 生產力指數分析中發現，整個光電產業只有在 2000 年至 2001 年間，因技術退步的影響大於綜合技術效率進步的影響，而使得生產力衰退，往後的期間皆呈現進步的態勢。而在次產業方面，綜合技術效率的退步導致光通訊產業在 2001 年至 2002 年間的生產力衰退；技術的退步使得 2002 年至 2003 年間的光輸出入產業產生生產力的衰退。 最後，在迴歸分析中的結果為存貨週轉率對於整體技術效率有著顯著的正向影響；研發費用率是顯著的負向影響。而在純粹技術效率部份，存貨週轉率有顯著正向影響；TCRI評等越佳，TCRI 值越低，純粹技術效率越好。 / Taiwan's industries are always connected closely with international market, and optoelectronic industry is no exception. Through keenly competence these years, it is still brilliant and boosts the lifeline of Taiwan's Technology industry with other Hi-tech industries. So this research uses data envelopment analysis as objective references to enhance production efficiency. First we divide the whole optoelectronic industry into several sub-industries according to the characteristics of their products, and calculate every firm and sub-industry’s values of technical efficiency, pure technical efficiency, scale efficiency and Malmquist index definitely. Then we analyze the key factors influencing production efficiency and offer references for helping optoelectronic industry better. This research is based on the data of 30 optoelectronic firms in Taiwan during the 2000-2003 periods. We use the number of employee, fixed assets, operating costs and operating expenses as input variables; net sales revenue and net income before taxes as output variables. Besides, the explanatory variables in regression analysis are the percentage of bonus accounting for operating net amount, inventory turns, debt ratio, the percentage of R&D expenses accounting for operating net amount, TCRI, share holding on directors. The result shows that inefficiency in the whole industry and sub-industries mainly comes from technical inefficiency. MPI demonstrates that productivity of the whole industry is declined only during 2000-2001 period and it is because of declined technology. And declined technical efficiency results in the declined productivity of fiber-communication industry between 2001-2002; declined technology results in the declined productivity of optical input/output devices industry between 2002-2003. Under regression analysis, the result shows that inventory turnovers have a significant positive effect on efficiency; the percentage of R&D expenses accounting for operating net amount has a significant negative effect on efficiency. And about pure technical efficiency, inventory turn has a significant positive effect; TCRI has a significant negative effect.

為了因應國內金融產業多元化、跨業經營的發展，立法院於民國90年6月27日通過「金融控股公司法」，截至2003年底止，我國一共有14家金融控股公司成立，而國內金融界也隨著一家一家金融控股公司的成立，掀起一波波合併及併購的風潮，由於金融機構未來互相合併、朝向大型化及多元化的趨勢明顯，因此，金融控股公司多角化的經營是否能夠發揮其效益是值得我們去探討的。 本文利用非參數邊界法，以及Ferrier et al.（1993）所提出的多角化經濟程度指標，來評估2002與2003年包含銀行、證券及保險營收三項產出的6家多角化金融控股公司之相對效率，並分析其無效率之來源，以及衡量其是否存在多角化經濟。另外，本文以投入導向的MPI評估台灣金融控股公司2002至2003年生產力變動的情形。 實証結果發現，6家包含銀行、證券及保險營收三項產出的多角化金融控股公司，都存在有多角化經濟的現象，表示金融控股公司多角化的發展與跨業經營確有其成本上的效益。另外，比較生產力變動的各項數值，多角化金融控股公司均低於非多角化金融控股公司，顯示多角化的效益並未反應在效率以及生產力的成長上。 / This paper adopts a nonparametric frontier method and the measure define by Ferrier et al. (1993) to evaluate efficiency and economies of diversification of 6 diversification financial holding companies which contain banking, security and insurance in Taiwan in 2002 and 2003. In addition, we use input-oriented Malmquist productivity index to study the productivity change of financial holding companies in Taiwan during 2002-2003. Empirical results indicate that 6 diversification financial holding companies all exhibit economies of diversification. Product diversification of financial holding company indeed has its effect on cost. In addition, compare every component of productivity change, we find non-diversification financial holding companies have better performance than diversification financial holding companies. The effect of diversification has not exhibit on the growth of efficiency and productivity.

台灣的IC設計產業總產值全球僅次於美國，自從九零年代中期成為我國極受矚目的產業。因此本研究所探討的主題為全球IC設計產業的生產效率分析，以2003年全球營收前卅大IC設計廠商為樣本。透過資料包絡法(Data Envelopment Analysis，DEA)，針對不同地區與個別廠商進行2000年至2002年的效率分析，最後進行Tobit迴歸分析，求得影響廠商生產績效的因子，提供本國廠商改善效率的參考，實證結果為： 1.DEA跨國比較的結果顯示，在2000年至2002年整體技術效率值最高的地區為美國，在2000年與2001年為台灣整體技術效率值僅次於美國，但在2002年卻落居第三。觀察個別廠商績效，Qualcomm、MediaTek、Marvell、ICS、Lattice、Pmc-Sierra與DSP Group等廠商績效最好，其整體技術效率值為1。 2.Malmquist生產力指數(MPI)跨國比較的結果顯示，臺、美、加三國總要素生產力均呈現退步的情形，2001至2002年，臺、加總要素生產力呈現進步，美國呈現退步。就個別廠商而言，在2000年至2001年間有四家廠商總要素生產力進步，在2001至2002年年則有十五家廠商總要素生產力呈現進步的狀況。 3.Tobit迴歸分析的結論為：存貨週轉率inventory turnover對整體技術效率有顯著的正向影響；負債比率與平均收帳期間均對整體技術效率有顯著的負面影響。研發費用率、經營年限與整體技術效率呈現正向關係，至於每人配備率則呈現負相關。 / The total output value of Taiwanese IC design industry is the globally second following United States. It had become the domestic gazed industry since mid 90s. Therefore, this research studies the production efficiency of global IC design industry and chooses the firms which sales globally ranked top 30 as samples. Through DEA, this thesis analyzes the efficiency focused on different regions and individual firms from 2000 to 2002. And finally, the Tobit regression model is proposed to find out the factors that influenced performances of firms and it could be reference for the domestic firms to improve their production efficiency and productivity. The results display: 1. By comparison with regions, the DEA results display that U.S.A. United States has the highest overall technical efficiency(TE) value during 2000 to 2002. Taiwan ranked behind U.S. both in 2000 and 2001 but dropped to the 3rd position in 2003. Observing performances of individual firms, Qualcomm, MediaTek, Marvell, ICS, Lattice, Pmc-Sierra and DSP Group performed as the best and their efficiency value is 1. 2. By comparison with regions, Malmquist Productivity Index(MPI) results display that the U.S.., Taiwan and Canada showed their Total Factors Productivity (TFP) to degenerate from 2000 to 2001. However, Taiwan and Canada showed their progressive TFP, progress in TFP but U.S.A. had a regressive TFP from 2001 to 2002. For one individual firm, there were only 4 firms’ TFP being aggressive from 2000 to 2001 and there are 15 firms’ TFP aggressive from 2001 to 2002. 3. The result from running Tobit regression models display that Inventory Turnover has significant positive effect to TE; Debate Ratio and Average Collection Period have significant negative effect to TE; R&D Ratio and Incorporated Period have direct relation with TFE and Equipment Per Employee has negative relation with TE.

本研究是第一篇針對台灣IC設計業的研發活動進行效率分析的論文。文中對研發的投入及產出變數作深入的探討，不僅以研發資本而非研發費用及加權研發人力為投入並且加入公司知識累積存量的概念。其中自有知識存量以自有公司前期累積專利申請數為替代變數。而產出部分也不僅考慮當年申請專利數核准數量還包括下一年度營業毛利。使用兩階段資料包絡分析法探討研發投入的運用效率。第一階段使用投入導向DEA-CCR與DEA-BCC模式評估2000年到2002年台灣上市上櫃IC設計業者運用研發資源能力所得出的研發效率值並作差額變數分析，第二階段採用Tobit迴歸分析尋找可能影響研發整體效率影響因子。最後，本研究依據研究結果提出對管理者及未來研究給予建議。 實證結果發現，〈聯發科〉是連續三年被評估相對整體效率為1的廠商，〈威盛〉與〈立錡〉為表現其次的廠商。就整體產業而言，三年的研發效率呈現低效率狀況，表示其研發資源有嚴重浪費與錯置的情形。效率分析中可看出研發資本（RK）對加權研發人力（RL）比值相對高的廠商，相對整體效率值呈現逐年負向趨勢。經過Tobit迴歸參數推估檢定本研究六大假說，人力素質、每人年約收入及研發人力密集度都與研發效率成正向關係。而員工平均年資與研發效率值呈現負向關係，與研究的預期關係不同。為第一線晶圓代工廠（聯電或台積電）轉投資的IC設計公司，研發效率並不因此網絡關係而有所影響。公司規模大小也不影響研發效率的表現。

我國全面開放保險市場後，壽險業所面臨市場競爭更加激烈，經營風險亦隨之增加，甚至影響其經營績效。本文以資料包絡分析法（DEA）評估2002年至2004年我國人壽保險公司的經營效率，並找出相對無效率壽險公司改善空間,再以Tobit截斷迴歸模型探討可能造成壽險公司之間經營效率差異的影響因素。其中由DEA技術效率評估結果發現：(一) 壽險公司整體技術效率平均值介於50.98﹪與70.15﹪之間，代表我國壽險公司在投入資源運用與配置上仍存有改善空間，在產出不變下，平均而言，可以節省29.85%至49.02%的資源使用量。（二）純技術效率值大於規模效率平均值，顯示造成壽險公司技術無效率之來源，資源浪費及生產規模不適當所造成的情況均有，但大部分來自於前者。迴歸實證結果顯示：（一）外勤兼職人員比率與技術效率具正向關係，顯示壽險公司僱用兼職人員招攬業務，相對專職人員可減少人事成本，可提昇經營績效。（二）國外投資比例與技術效率具正向關係，即壽險公司因國外投資商品多樣化選擇，可靈活運用資金，提昇技術效率。（三）佣金率與技術效率具正向關係，代表壽險公司支付業務員佣金及津貼愈高，愈能激勵業務員積極招攬業務，增進公司業務績效，以提高技術效率。（四）逾期放款比率與技術效率為負向關係，即壽險公司逾期放款比率愈高，績營效率愈差。（五）市場占有率與技術效率為正向關係，顯示壽險公司市場占有率愈高，對市場的控制能力較佳，在產品銷售亦具有規模經濟，可提昇經營效率。（六）外內勤人員比例與技術效率為負向關係，表示外內勤人員比例愈高，壽險公司易忽略內勤行政人員在核保、理賠及客服等作業品質，將影響公司產品創新及保戶後續權益等，不利公司經營績效。

本研究利用資料包絡分析法探討被併購標的銀行於購併前後是否能增加效率，以及具有何種特徵之銀行較易成為金控公司併購之對象。 研究結果發現標的銀行於購併之後，雖能促進效率，但結果並不顯著，顯示合併之後效率提升是綜合標的銀行之高資產品質、高獲利能力、低利率風險及分行數少才使購併後效率提升。在標的銀行的特徵方面顯示當銀行處於非遞減規模報酬、財務上呈現弱點，但銀行資本結構較佳、利率風險較低時，容易成為金控公司購併的對象。 / This paper tried to apply Data Develop Analyis (DEA) to examine whether M&A could promote the targeted banks’ efficiency and the criterions when financial holding companies choose the targeted bank. The experical resoults suggested that although the targeted banks denoted higher efficiency gains, however, the gains do not achieve statiscally signicant level. The results implied that the higher efficiency gains might come from the targeted banks’ high quality assets, greater profitability, lower interest risk and less number of branches. On the other hand, the banks operated under non-decreasing return to scale, financially vulnerable banks, better capital structure, and lower interest risks were more likely to be the acquisition targets.

中國大陸於1986年申請重新加入WTO，經過15年的長期努力及多方談判，並且在各種產業上做出重大讓步之後，於12月11日正式成為第143個正式的會員國。加入WTO之後，在大陸金融市場規模龐大且成長迅速的吸引之下，市場的開放必然會吸引大量的國際保險業者進入大陸。另外，與一般開發中國家的情況相似，大陸的金融產業相對於其他產業而言是發展較為遲緩的產業，金融機構進駐後造成的衝擊必然十分嚴重，因此大陸當局應儘早加以準備與因應。 本研究採用資料包絡分析法進行效率值之計算，並使用大邊界法建構出單一效率邊界，探討大陸產險業在加入WTO前後的效率變動情形。本研究的結果如下:1.根據單變量無母數統計分析，整體產險業在加入WTO前後三個效率值雖呈正向關係但不顯著，表示階段性的開放是較理想的措施。2.非中資公司的整體技術效率值、純技術效率值與規模效率值均高於中資公司，顯示非中資公司其全球化的經驗較中資公司更好、更成熟。 / Mainland China reapplied in 1986 to join WTO, passed through 15 years long-term endeavor and negotiates in every way, and made the significant concessions after each industry, on December 11, 2001 officially became the 143rd official member nation. After joining the WTO, the mainland's financial market scale and rapid growth attract, opening of the market will attract a large number of international insurance industry to the mainland. Furthermore, with most developing countries in similar circumstances, the mainland's financial industry compared to other industries in terms of development is relatively slow industries, financial institutions stationed after the impact is inevitable, therefore, the mainland authorities should be prepared as early as possible and to respond. This research applied Data Envelopment Analysis (DEA) to measure efficiency scores, and applied Grand Frontier to measure the trend of the efficiency change before and after joining WTO. The results of this study are as follows: 1. Based on the univariate statistical analysis, overall in the property insurance industry after joining the WTO three efficiency values have shown a positive relationship but not significant, said the gradual opening is a relatively ideal measures. 2. Non-Chinese company's overall technical efficiency, pure technical efficiency and scale efficiency were higher than the value of Chinese-funded companies that show non-Chinese-funded companies in their global experience are better and more mature than those Chinese-funded companies.

本研究採用資料包絡分析法球員效率與NBA官方網站效率值來探討其對球員薪資之關聯性。本研究除探討外籍球員與美國籍球員間效率及高薪球員與低薪球員間效率差異，並同時比較資料包絡分析法(DEA)所計算之效率值與NBA官方網站所提供之效率值何者與薪資之關聯性較高。 實證結果發現，外籍球員與美國籍球員效率無顯著差異；但是高薪球員的效率顯著的優於低薪球員。另外也發現薪資與國籍間之關聯，及國籍與效率間之關聯性並不顯著。最後，在Vuong test比較資料包絡分析法之效率與NBA效率值與球員薪資間之關聯性的測試，雖然兩類效率值前一期與薪資之關聯性都成正相關，但是DEA所計算之前一期效率值高於NBA官網之前一期效率值與薪資關聯性，顯示DEA所計算之效率值可以比官網之效率值更能做為球員薪資談判之指標。 / This research applies Data Envelopment Analysis and examines the relationship between NBA players’ salaries paid and efficiency performance. The research not only compares the efficiency difference between players paid for different salaries, Local players and Foreign players, but also construct a model to examine the explanatory ability about player’s salaries between DEA efficiency scores and NBA official efficiency scores. The empirical results suggest that there is no difference between the local players and the foreign players, but the efficiency performance of high-paid players is better than the low-paid players. After we controlled the other variables, the empirical results illustrated that player’s nationality and salaries has no significant influence in player’s efficiency. The Vuong test results reveal that the pervious period DEA efficiency score demonstrated a higher explanatory ability than the pervious period NBA official efficiency score. The finding suggests that the DEA efficient approach could be a better index for players’ salaries negotiation than NBA official efficiency score.
