For as long as managed mutual funds have been in existence there has been a desire to accurately assess their relative performance against each other, and also their respective performance in relation to an appropriate stock market index. There has been a specific interest in whether the expensive, professionally managed mutual funds can justify their high cost with respect to low cost, simple index trackers by producing superior, post-cost performance, and this proposition is implicitly tested within this thesis. The aim of this thesis is to undertake an empirical assessment of the managerial performance of mutual funds utilising a three-stage DEA-SFA-DEA methodology which combines linear mathematical programming (DEA) and stochastic frontier analysis (SFA). Specifically, this thesis focuses on evaluating the managerial performance of UK domiciled open-ended investment companies (OEICs) and unit trusts (UTs) over a three year period from 1st January 2008 to 31st December 2010. Various DEA models are utilised including CCR, BCC and SBM DEA models with various orientations, and also versions of these DEA models which make use of the SORM procedure. These are used to carry out an initial evaluation of the managerial performance of the OEICs/UTs, before two of these DEA models are combined with SFA regression analysis in a three-stage DEA-SFA-DEA methodology to purge the influence of environmental factors and statistical noise, thus leading to a more robust evaluation of the true managerial performance of the OEICs/UTs under assessment. The results of this thesis extend support to the premise of the Efficient Market Hypothesis (EMH) that financial markets are information efficient , and thus it is not possible, given the information available when the investment is made, to consistently obtain returns in excess of the average market return on a risk-adjusted basis, and this thesis does so through the use of a novel approach.

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.

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.

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。

本研究旨在運用資料包絡法(data envelopment analysis, DEA)分析「教育部公私立大學校務資訊評鑑系統」中90至92學年度我國50所大學校院在研究與教學上之經營效率。研究問題有四：(1)國內大學校院教學與研究之投入與產出性指標系統分別為何？(2)國內各大學校院之相對效率值為何？改進策略為何？(3)國內各大學校院之發展類型為何？(4)國內各大學校院之發展趨勢為何？本研究考量投入項與產出項之重要性，編製「評估我國大學校院之發展策略指標權重專家調查問卷」以國內30位高等教育行政主管為調查對象進行層級分析取得指標相對權重，並套用於確定區域模式進行效率值之估算。指標係依據文獻探討與積差相關的同向性檢定，在研究效率上選擇6個投入項及5個產出項；在教學效率上選擇7個投入項及2個產出項。所使用之統計分析包括：積差相關、層級分析法、資料包絡法(效率分析、差額變數分析、參考集合分析、Malmquist 生產力指數)、Kruska-Wallis H檢定、Mann-Whitney U檢定、Tobit迴歸。 本研究得到以下六項結論： 一、本研究依大學生產關係架構所擬定之20項指標經相關分析、專家權重以及資料包絡法三種層面之分析，可作為以效率觀點評估我國經營效率的指標系統。 二、研究投入資源重專任副教授以上人數，研究產出重專任教師發表重要期刊論文篇數；教學投入資源重專兼任教師人數，然而，授課時數與約當畢業生人數在教學產出上同等重要。 三、三個學年度間，研究面向中有5校均為整體技術有效率，40校均為整體技術無效率；教學面向中有1校均為整體技術有效率，48校均為整體技術無效率。研究與教學無效率之原因均導因於純技術無效率，分別約浪費22.4%-27.2%以及26%-27.3%的投入資源，規模無效率影響較小。 四、不同權屬別對於整體技術效率之影響，主要源自於純技術效率；不同學校規模對於整體技術效率無影響，其係綜合學校規模越大純技術效率越差，但相對規模效率越佳的結果。 五、國內各大學校院發展，研究型大學以國立大學與醫學校院為主；教學型大學以師範校院與私立大學為主。 六、就三個學年度發展趨勢，整體而言研究效率提升，教學效率衰退，而各大學發展趨勢除整體技術效率略有消長外，35校在三個學年度發展類型均為一致。 / The purpose of this study is to assess the research and teaching productivities of 50 Taiwanese universities and colleges over the period of academic years 2001-2003. Research questions include: (1)What is the index system to assess school performance? (2)How many efficiency scores do these schools get? Inefficient units can implement what kinds of improvement to achieve efficiency? (3)What are their development styles? (4)What are their development tendencies? In order to consider weight restriction on inputs and outputs, author compiles “the expert questionnaire of assessing development strategy in Taiwanese universities and colleges”, and invites 30 specialists to answer, including 15 principals in higher education institutes and superintendents from Ministry of Education and 15 professors majoring in this field. Assurance region model with weigh indexes is used to calculate the whole efficiency scores. According to the result of literature reviewing and isotonicity test, author picks out 6 inputs and 5 outputs in research dimension and 7 inputs and 2 outputs in teaching dimension. Some statistic methods are used, including Pearson correlations, analytic hierarchy process, data envelopment analysis, Kruska-Wallis H test, Mann-Whitney U test and Tobit regression. Results based on data show as follows: 1. Through statistic analysis, those indexes the author drafts can be used to assess the productivity of Taiwanese higher education institutes practically. 2. In research dimension, the most important input is the number of assist professor, output is academic paper accepted by prestigious journals. Besides, in teaching dimension, the most important input is the number of faculty; however, the amount of class hours is equal to the amount of graduates on output part. 3. In research dimension over three academic years, 5 schools were efficient in each year; however, 40 schools were inefficient in each year. Furthermore, in teaching dimension, only 1 school was efficient in each year; in contrast, 48 schools were inefficient. Both of research and teaching inefficiency mainly came from pure technical inefficiency, wasted 22.4%-27.2% and 26%-27.3% separately. 4. The effect of different authorities upon the efficiency mainly came from the pure technical efficiency. In addition, because of the effect mixed pure technical efficiency (PTE) with scale efficiency (SE) the effect of the different school scale upon the efficiency was non-significant. 5. Research universities are mostly from national universities and medical colleges. In contrast, teaching universities are mostly from private universities and normal colleges. 6. As a whole, research efficiency score grows but declines in teaching. Beside of some fluctuations on efficiency score, there are 35 schools maintain their development styles stably.

雖然國內論文對企業併購的研究不在少數，範圍涵蓋併購的動機、類型、績效、策略與法律等，但針對敵意併購的研究則甚少，且研究大多著重於目標公司反接管策略的探討，鮮少對敵意併購後的績效進行討論。因此，本研究欲藉由資料包絡分析法，衡量我國敵意併購目標公司於併購發生後的經營效率變動的情況，及探討國內企業敵意併購之動機。 本研究以1986年至2001年台灣的併購活動為研究對象，實證發現主併者在選擇善意或敵意併購目標時有所差異；主併者選擇在善意併購目標公司時，對於目標公司之經營績效並無特別偏好；但在選擇敵意併購目標公司時，則以經營效率不佳者為對象，並透過敵意併購改善其經營效率；此外，敵意併購目標公司在替換掉管理能力不佳的管理者後，其效率進步的程度大於善意併購目標公司。因此，本研究樣本顯示台灣敵意併購支持懲戒式接管的動機假設。 / / Many scholars did researches on merger and acquisition (M&A) before, and the research scope involved motives, types, performance, strategies and laws of M&A; however, few of them mentioned hostile takeovers. Besides, most of hostile takeovers researches focus on anti-takeovers defenses of target companies, only a few researches discussed about post-takeover performance after hostile takeovers. This research attempts to measure the efficiency change of target companies after hostile takeovers, and discuss the motives of hostile takeovers in Taiwanese enterprises. The sample year includes Taiwan from 1986 to 2001. The research findings reveal that in the samples of friendly takeovers, there were no specific preference for choosing the targets companies. On the other hand, in the samples of hostile takeovers cases, the research findings denote that most of the target companies were underperformance, which triggers the takeover action. Moreover, the result demonstrates that hostile takeovers present better performance improvement than friendly takeovers do. The findings support hostile takeovers disciplinary motives implication in Taiwan.

近年來台灣景氣持續低迷，台灣綜合商品零售業的成長也受到不小的衝擊，在市場漸趨成熟與飽和的情況下，產業內競爭也漸趨激烈。如何在外在經濟環境欠佳，內在市場飽和下，有效提升經營效率，加強產業競爭能力，是目前台灣綜合商品零售業者最重要的課題。 　　本研究以資料包絡分析法（Data Envelopment Analysis）為基礎，並結合Metafrontier分析法，針對台灣地區2000年到2006年25家綜合商品零售業者，以客觀的投入產出資料進行廠商的經營效率分析。本研究結果顯示： 　　1.整體而言，連鎖式便利商店的經營績效平均處於相對有效率狀態，購物中心的經營績效平均處於相對無效率狀態。 　　2.廠商技術無效率的原因主要為純粹技術效率的問題。廠商的規模報酬狀態與所屬業態關聯不大，而與廠商是否屬於連鎖集團較有關聯。 　　3.比較metafrontier模型與group frontiers模型所評估的效率值，顯示各業態廠商的平均技術水準有顯著差異，連鎖式便利商店的效率水準較接近metafrontier的效率邊界。 　　4.依據Norman and Stoker（1991）的效率值強度分類方法，發現在兩模型之下，各業態廠商屬於「邊緣無效率單位」與「確實無效率單位」的比例都較大，表示經營績效有很大的改善空間。 　　5.差額分析與敏感度分析方面，百貨公司業與超級市場業在兩模型之下的結論不一致，推論應是兩者評估的廠商樣本，其衡量的技術水準不同。各廠商依循group frontiers模型所得結論改善經營績效，將可以在業態內成為相對有效率的廠商，但如果想要進一步提高效率，則必須改變廠商本身所處的業態環境所造成的技術水準限制，便可依循metafrontier模型所得結論改善經營績效，所以選用何種結論，仍須由業者依據廠商未來發展自行判斷。 / Since the recession in Taiwan economy has arrived in recent years, it has a great effect on the growth of the Taiwan retail sale of general merchandise. Because the market has been saturated, the competition has become fierce in this industry. How to improve the management efficiency and the industrial competitiveness in the present economic environment is the most important issue of the Taiwan retail sale of general merchandise. 　　This study uses inputs and outputs data of 25 DMUs of the Taiwan retail sale of general merchandise from 2000 to 2006, applying Data Envelopment Analysis with Metafrontier model to evaluate the operational efficiency of those firms. The findings of this study are as below: 　　1. On average, the chain convenience store industry shows more technically efficient than the shopping mall industry. 　　2. The main source for the firms being inefficient is pure technical inefficiency. The returns of scale of the firms are not much related to the types of business operation, but to the firms being the chain store ones or not. 　　3. Comparing meta-frontier model with group frontiers model, we find that there are significant differences in the average technical efficiency levels among the various types of business operation, and the chain convenience store industry is most close to meta-frontier. 　　4. According to the classification of the efficiency by Norman and Stoker (1991), we find a major part of the firms is marginally inefficient and distinctly inefficient. It implies there is a great room for the firms to improve their managerial performance. 　　5. The slack analysis indicates there are differences in the resource wastes between the department store industry and the supermarket industry. The differences mainly come from the technological differences between the two industries. The information generated from the group frontier model is helpful to improve the firms’ efficiency within the group. However, if the firms want to further improve their efficiency, they should rely on the information from the meta-frontier model, which sheds light on the technology gap among sub-industries.

有鑑於我國與大陸方面是否應簽訂ECFA仍有許多疑慮，本研究欲就香港與大陸所簽訂之CEPA協定對香港銀行業經營效率有何影響加以探討，以便對台灣未來可能簽訂ECFA時提供台灣銀行業相關參考及對策。 本研究針對2000年至2007年的18家香港地區銀行以及30家台灣地區銀行，採用資料包絡分析(DEA)計算業者之經營效率，最後控制銀行業者本身之財務特性及總體經濟環境因素，應用Tobit迴歸比較分析實施CEPA對香港銀行業之影響及台灣與香港業者之差異。 研究結果顯示港銀行業之經營效率八年間均較台灣銀行業為佳，此外CEPA協定之採用整體而言對台灣以及香港銀行業均無顯著影響，雖然協定採用後之第三、四兩年，香港銀行業之效率顯著高於實施後之前兩年與台灣銀行業者，亦即CEPA之效益要到協議三及四之後才顯現出來。因此可知CEPA簽訂後，效益不會立即顯現，須有更多的開放例如CEPA三及四對營業額及資本額的放寬才有可能顯現直接之效益。此點應可作為台灣未來與大陸談判時應考慮之因素。 / Since Taiwan still disputes whether to sign Economic Cooperation Framework Agreement, (ECFA) with mainland China or not, this research tries to analyze the efficient change of Hong Kong banking industry before and after singing Closer Economic Partnership Agreement (CEPA) with mainland China. And hope to gain some understandings about the effect of singing CEPA, so that to provide some strategic references for singing EFCA in the future. The research data draw from 2000 to 2007 of the 18 regional banks from Hong Kong and 30 regional banks from Taiwan. The research applies data envelopment analysis (DEA) to evaluate the operating efficiency of the banks. After controlling banks’ financial characteristics and macro economics variables, the Tobit regression denotes the following suggestions. The efficient of Hong Kong banking industry showed a better efficiency than Taiwan banking industry. After signing CEPA for two years, Hong Kong banking industry finally revealed a significant improvement than first two years as well as Taiwan’s banking industry. The results suggest that signing CEPA does not immediately increase the efficiency of the industry; the agreement might need fewer restrictions, such as fewer amounts of sales restriction and less capital restriction in CPEA III and IV, in order to boost the performance of the industry. The results should provide a good strategic consideration about the future EFCA talk for Taiwan.
