本篇論文應用Rubin (1973)、Rosenbaum and Rubin (1983、1985a,b)所發展的配對方法(Matching Method)探討兩個議題，其一是評估企業從事社會責任行為是否可以改善績效，另一則是探討銀行加入金控後對其績效的影響。 / 針對第一個議題，我們將FTSE All-share 指數中被收錄於英國FTSE 社會責任指數的成份股定義為社會責任企業，未被收錄者定義為非社會責任企業，應用配對方法，根據特性變數是否相近為依據進行樣本配對。實證結果發現，不論使用配對前或是配對後的樣本進行分析，皆找不到社會責任企業的平均績效優於非社會責任企業的證據；相反地，部分的證據顯示社會責任企業的財務績效相對較低，因此我們的分析結果傾向支持焦點移轉假說，社會責任行為對財務績效的影響效果為負。 / 另外，我們以遠見雜誌於2006 年公佈的企業社會責任調查為基礎，將衡量企業社會責任績效的三個層面－社區參與、環境保護與財務透明，透過投資組合分析與迴歸分析來評估公司承擔社會責任與財務績效之間的關聯性。實證結果發現，第一，平均來說，公司的社會責任評分愈高，在評比結果公佈後的股票報酬愈低，兩者之間呈現負向關係；第二，公司在不同層面的社會責任行為對於股價報酬的影響具有差異性；第三、透過公司的長期財務資料發現，社會責任評分高的公司其長期平均會計績效相對較佳，但長期平均的股票報酬相對較低，表示社會責任型公司不一定是一個好的投資標的；最後，我們找不到支持社會責任行為可以做為公司績效保險的證據。本文使用各別層面的評比指標，更廣泛地評估社會責任行為對財務績效的影響，改進既有文獻中僅使用單一指標的不足之處。 / 就第二個議題而言，同樣地應用配對方法，根據銀行的特性變數是否相近為依據進行樣本篩選，利用台灣上市上櫃的銀行在2002 年第1 季至2006 年第2季的資料，我們發現在樣本配對前，平均來說，金控銀行在15 個CAMEL 績效指標的表現上皆相對較佳；樣本配對後，金控銀行除了在費用比率之外，其他的評比指標仍相對優於獨立銀行；不論使用配對前或配對後的樣本做分析，皆未出現金控銀行績效顯著較差的證據，因此，我們的實證結果偏向支持綜效假設，銀行加入金控對績效的影響效果為正向。 / 我們的研究架構與方案評估與政策衝擊分析文獻中的方法相一致，而貢獻則在於我們考慮樣本之間特性變數的差異性，進而以樣本配對的方式修正這個差異性，將有效降低既有文獻中在檢驗上述兩個議題上的選擇偏誤問題。 / In this thesis, we apply several matching methods, develop by Rubin (1973)、Rosenbaum and Rubin (1983, 1985a,b), on examing the effects of Corporate Social Responsibility (CSR) on firm financial performance (CSR-effect) and on evaluating the effects of banks being subordinated to FHC on CAMEL indicators (join-FHC effect). / For the former application, two competing hypotheses, social impact hypothesis and shift of focus hypothesis, are proposed, where the former suggests that CSR has a positive relation with performance and the latter are opposite. To ensure the CSR-effect is not contaminated by other factors or the sample is randomly drawn, we employ four matching methods, Nearest, Caliper, Mahala and Mahala Caliper to match the characteristics of the firms with CSR (CSR-firms) and without CSR (NonCSR-firms) to get rid of sample selection bias. Although the four methods yield slightly different results, to our surprised, firms engaging in CSR activities obtain lower values on the return on assets, return on equity, return on sales and earnings per share. Therefore, CSR at the very least does not improve the firm performance, supporting the shift of focus hypothesis. Engaging in CSR activities lead to more pain than gain, at least in the short run. / On the CSR topic, using a set of disaggregated social performance indicators for community participation, environmental protection and fiancail transparency from the Global Views Monthly, we examine the relationship between CSR and financial performance of TSE listing companies. Our main results show that first, scores on composite social performance indicators are negatively related to stock returns and this relationship cannot be rationalized by multi-factor models for explaining the cross-sectional variation in stock returns. Second, the effects of three disaggregated social performance indicators on stock returns are differenct among industries. Third, aggregated social performance indicator is positively related to long-term accounting performance but negatively related to long-term market performance, and thus implies that good companies are good in books, but not good investments. Finally, firms with high CSR ratings do no exhibit smaller decline of their financial performance during stagnations and thus not support the view that CSR is insurance of financial performance. / The second application, two hypotheses, synergy hypothesis and specialization advantage hypothesis, are raised too, where the former suggests that FHC-banks performer better and the latter are contrary. Above four matching methods are still used to fix the characteristics of two groups of banks in order to correct for sample selection bias. Based on after-matching samples, most of our empirical results suggest that FHC-banks, on average, outperform independent banks on most of indicators on capital adequacy, asset quality, earning ability and liquidity but not on management ability and being FHC-banks at the very least does not deteriorate the performance of banks, making our conclusion favors the synergy hypothesis and against specialization advantage hypothesis in Taiwan. / Our framework is identical to many applications of matching method such as Persson (2001), Hutchison (2004), Glick, Guo and Hutchison (2006), and are also parallel to standard medical and biological research.

知識經濟時代，智慧財產權已經成為公司經營的策略重點，不再只是著重於法律與科技等構面，觸角更擴張為經營管理、商業競爭、企業併購、財務規劃與驅策新事業的重要工具。新的專利侵權原告（The New Breed of Patent Infringement Plaintiffs）便趁此一熱潮悄然誕生，美國稱之為「Patent Troll」，其不為營運研發、純粹在全球購買專利，以創造利潤與策略佈局考量為主，挾著專利持有人的地位大張旗鼓尋找「交易」對象，以訴訟為手段作為談判的籌碼，到處發警告函以獲取權利金。「Patent Troll」不僅在法律制度上引發爭議，更提高企業在智財管理方面的困難度，其對專利體系上的影響是全面性的。 本文第一章主要說明本論文之研究動機，包含專利訴訟新趨勢、新的商業營運模式，以及順應而生的「Patent Troll」之情形，闡述其所造成與被授權人間議價能力失衡之現象，接著闡述其對交易關係的影響以及美國法上相應適用的法律原則之變化，最後針對台灣的現況做一說明並向企業提出策略上之建議。 第二章蒐集並整理國內外與「Patent Troll」相關問題的爭議及探討。首先針對智慧財產服務業(IP Service Corporation)及智財控股公司(IP Holding Company)等名詞作一基本介紹。次對「Patent Troll」之名詞、定義、由來及分類做一整理介紹，接著說明「Patent Troll」之特徵、功能及商業模式。最後則針對各方文獻對於專利管理流程以及企業營運策略等建議做一整理分析。 第三章針對「Patent Troll」此一名詞做全面性的介紹與探討。首先對「Patent Troll」的定義、名詞爭議、發展歷史及與類似名詞的區辨為一概括式的介紹，本文將「Patent Troll」定名為「專利地痞」，並認為分析特徵可歸納為下列七項，只有當七項特徵都符合時才是本文所指涉之專利地痞：（一）為專利權人的個人、獨立發明人或公司；（二）藉由購買專利（如MercExchange）或進行技術創新(如Lemelson)；（三）不製造生產產品；（四）非提供專利服務；（五）鎖定目標公司（Target Company）：該目標公司必須是獨立發明製造技術，真正使用該專利，欠缺專利授權，在商業上成功，並且出現且已投入不可回復的損害；（六）以訴訟與禁制令作為要脅；（七）以達和解授權以獲取權利金等創造利潤及策略布局。接著說明「Patent Troll」的分類，以掌握其可能存在的不同態樣，本文將專利地痞分類為「發明型」專利地痞」，以及「購買型」專利地痞。然後就其特徵、優勢及商業模式加以闡述，歸納出一些共通的特徵，本文認為專利地痞的商業模式可以分成下列幾個步驟，第一階段為累積專利期，第二階段為授權協商期，第三階段則為專利訴訟期。各階段之間有其前後順序，並且環環相扣，除了第一階段需投入成本外，另外兩個階段均以創造利益為最終目的。最後再就全球各主要國家關於「Patent Troll」的現況進行討論並提出結論，以此部分的撰寫與結論作為第四張及第五章關於法律面與管理面相關議題批評檢討的基礎。 第四章探討「Patent Troll」在美國法上涉及的相關法律爭議問題，期以此觀察緣起環境變遷的方式了解國內外法制環境的差異，並定位台灣在此一進程中所處之發展位置，以解析台灣關於「Patent Troll」此議題重視之必要與否以及應該採取的態度與方法。首先以美國法上針對「Patent Troll」此一議題在行政、立法和司法的變革為引，帶出此一議題影響層面的全面性。次專注於美國法上關於立法上「專利改革法案」對於解決「Patent Troll」問題所做的努力，如前已提及之專利先申請原則、專利侵權損害賠償計算基礎、惡意侵權損害賠償、專利核可後非經訴訟程序的異議制度（Post-Grant Opposition）和專利侵權訴訟管轄權等。接著以法院判決的變化演進，如前述主要提及之2006年eBay v. MercExchange一案中對於禁制令核發原則的確立、2007年KSR v. Teleflex一案中對於可專利性原則（Patentability）的解釋運用，2007年MedImmune,Inc. v. Genentech一案對於確認判決（Declaratory Judgment）行使範圍的解釋。2007年Microsoft v. AT&T 針對域外效力（Extraterritorial Impact）的確立，以及2007年In re Seagate一案對於惡意侵權(Willful Infringement)的認定等。最後針對個別修正法案或法院判決的變遷對專利地痞的影響做一說明。 第五章提出企業面對「Patent Troll」此一威脅時所能採取的因應策略。將以第三章所分析之專利地痞商業模式三步驟為本，針對專利地痞行使各該步驟時，企業可能採取的因應策略。第一階段的累積專利期，包含有專利資訊管理、專利購買與公司併購、延攬IP專業人才、保險分擔機制與提撥準備金、技術創新設計、專利交叉授權、專利策略聯盟、契約條款規劃和其他新型態的因應策略等；第二階段的授權協商期，包含有專利評估、和解授權，確認訴訟；第三階段的侵權訴訟期，則有專利訴訟程序、侵權認定程序、善用迴避設計、提出異議制度、提出專利再審查、慎選繫屬法院，以及採取團體訴訟以資因應等。期以一相關流程使企業得以瞭解其現階段落在何種情況時應採取何策略始得降低風險並妥善因應。 第六章為本論文之結論建議，結論部份，將前述第三章、第四章和第五章所提出之觀點作一概括性的總結。建議部分，即就我國產官學各界及現行法制面對「Patent Troll」問題可能適用之解決方式加以檢討並提出建議。 / In the knowledge-based economy era, intellectual property has become the focus of business management strategy. The concerns of intellectual property management extend from law and technology to management, market competitions, mergers and acquisitions, financial plans, and start-ups. The trends also bring forth a new breed of patent infringement plaintiffs, Patent Troll, who do not undertake R&D and purchase patents worldwide as their main profit and business strategy. Those patentees utilize litigation as measures to bargain with their “clients” to obtain loyalties. The issue of Patent Troll is influential in the Patent system. It rouses controversy in legal system and increase difficulty for industry in intellectual property management. Chapter I describes the main concern of this thesis, including new trends of patent litigation, new business model, and “Patent Troll.” The chapter will elaborate an imbalance of bargaining power between licensors and licensees cause by patent troll, the influences of patent troll to IP transactions, and the changes of legal principles under U.S. patent law and judicial decisions. The chapter will outline the current situation in Taiwan and propose some strategy to industries. Chapter II involves relating issues on "Patent Troll" in Taiwan and abroad. First, the chapter will introduce the definition of IP Service Corporation and IP Holding Company. Then the chapter will elaborates and discuss patent troll from the name, definition, classification, origin, features, functions and business models. At last, this chapter will analyze the patent managerial process and operating strategies for the industries. Chapter III focuses on a comprehensive introduction towards patent troll. First, the article elaborates the disputes on the definition, the term, the history and the differences between similar terms of patent troll. A Patent troll should meet all the following seven characteristics, (a) patent owner/independent inventor/company; (b) Compare purchase of rights (MercExchange for example) vs. invention (Lemelson for example); (c) Does not Make, Use, Sell, Offer to Sell, Or Import Patented Article/ Does not Use/Practice Patented Method; (d) no IP Service; (e) Target company (infringer): The target company must be an independent inventor of the technology, has real use of the patent, lacks of patent license, has successful business and devotes substantial investments; (f)Threat of litigation & Injunction; (g) Demand for licensing fee. Then the article describes the classification of patent troll in order to grasp the potential types of it. Patent troll in this chapter will be classified as "inventor" one and "purchaser" one. The business model of patent troll can be divided into three stages: (a) cumulative period ;(b) licensing and consolation period and (c) patent litigation period. The three stages are of time sequence and closely linked together. The “Patent Troll” needs to invest money only in the first stage and take profit creation as the ultimate goal in the other two stages. Finally, the chapter describes and discusses the developments and current status of patent troll in some major countries in the world. The observation and discussion will be served as the foundation for further discussion in the following chapters. Chapter IV focuses on the legal principle changes under U.S. patent system in three dimensions: administration, legislation and jurisdiction and illustrates the effects that occur to patent troll. The changes of administration focus on three parts: the limitation of continuation application, the limitation of divisional application and the limitation of claims. In legislation, the changes focus on “Patent Law Reform Act”, including the first-to-invent to first-to-file principle, the calculation basis of damages, enhanced damages, post grant review procedure, and venue and jurisdiction. The changes of jurisdiction focus on five verdicts and cases, eBay v. MercExchange, KSR v. Teleflex, MedImmune, Inc. V. Genentech, Microsoft v. AT & T, and In re Seagate. The chapter will elaborate the influences of those changes and decisions on the business model of patent troll. Chapter V proposes some possible solutions and strategies to industries when they are confronted with the threats of patent troll. This thesis takes the three stages of patent troll’s business model as a foundation and proposes the strategies for industries against patent troll during different stages. The strategies for first stage are IP information management, patent purchase, mergers and acquisitions of companies, IP professionals recruitment, insurance mechanism, technology R&D, patent cross-licensing, patent alliances, contract planning and other new types of strategies and so on. The strategies for the second stage include patent evaluation, authorization of reconciliation and declaratory judgment. The strategies in the third stage are patent litigation, infringement procedures, patent design around, patent re-examination, choose of venue and jurisdiction and group litigation. The thesis expect to enable industries to understand what stage they fall on and what strategies they can adopt, with the proposal of management procedure. Chapter VI will be the conclusions of this thesis and will include suggestions on the issue of patent troll to industries, government and academia.

過去許多企業，將企業原本擁有的智慧財產（例如：專利、商標、營業祕密…）與企業的其他資產、負債，分離出來，成立智慧財產控股公司，並透過智慧財產供股公司的經營管理，獲取大量的租稅利益。此一租稅規劃工具雖然已引起稽徵機關的注意，但運用得當，仍可為企業創造可觀的利潤。 智慧財產控股公司的設立架構，母公司通常會在低稅率的國家或州，設立一完全控股的子公司，由智慧財產控股公司自行創設、或自母公司繼受智慧財產。智慧財產控股公司授權的對象，可能是母公司、亦可能為不相干的第三人。 智慧財產控股公司的租稅效益，來自智慧財產控股公司通常選在低公司稅率（甚至零稅率）的地區設立，對於權利金收入予以免稅的地區。母公司付給子公司的權利金費用，母公司可作為費用扣除，藉以降低母公司的所得稅。智慧財產控股公司可透過發放股利，或對母公司融資等方式，解決母公司的資金需求。 透過智慧財產控股公司進行租稅規劃，最重要面臨『移轉定價』與『避免濫用租稅協定』，因此智慧財產控股公司進行的關係人交易，不能是純為獲取租稅利益的假交易，必須有商業實質。 / Over the last decade or so, many businesses generating significant revenue from intellectual property such as patents, copyrights, trade names and marks, software and know-how (the IP Assets) have organized intellectual property holding companies (IPHCs) to reduce federal and state taxes while separating valuable IP Assets from other corporate liabilities. Recently, states have started to aggressively challenge this tactic. However, substantial state and federal tax savings can still be realized if IPHCs are organized and operated correctly. The structure of an IPHC is fairly simple. The parent corporation typically creates a corporate subsidiary in a state or in a foreign country where little or no taxes are imposed . IP Assets are created by or transferred to the subsidiary. The subsidiary enters into license agreements under which the parent corporation and non-related corporations agree to pay the IPHC royalties in exchange for an exclusive or non-exclusive right to use the IP Assets. Since most IPHCs are organized in jurisdictions with no income tax, the royalties received by the IPHC are generally tax-free. In addition, the parent corporation that paid the royalty typically can deduct the payment as a deductible expense, thereby reducing the parent's income or franchise tax liability. In some circumstances, IPHCs can make tax-free dividend distributions or loans to the parent corporation. The key issue IPHC should consider is “Transfer Price Issue” and “Anti Treaty Shopping Issue”. Transactions between related parties can’t be shame transaction, business substance is required.

本研究主要探討日本企業於90年代面臨泡沫經濟、金融風暴、全球化、資訊經濟以及服務經濟的變革。許多大企業過去因為追求成長而組織逐漸膨脹，使得面臨外部環境快速變遷時，發生反應遲鈍、人員創新力不足、資源過度分散的現象。在這一波變革當中，日本企業一方面要重整組織，一方面要踏入新的事業領域，使得變革格外艱困。90年代的泡沫經濟，正好提供日本企業深思反省的機會，也讓研究學者提供了企業變革的最佳樣本。 由於日本政府正式將獨占禁止法的純控股公司禁令解除，預計2001年進一步更改稅法為連結經營的模式，因此被禁止五十年的控股公司經營模式將被許多大企業多所採用。本研究藉由三大綜合電機廠商－株式會社日立製作所、株式會社東芝、三菱電機株式會社－的探討，逐步了解日本企業這一波組織變革的手法，以及控股公司組織架構在企業變革上所扮演的角色。 本研究從策略思維、組織架構、經營系統著手探討，發現在各個環節上都是企業變革的重要考量。日本企業的經營策略逐漸轉型為以中期規劃為主；原本製造導向轉變為以服務為導向；80年代過張造成的的資源分散，現在則努力執行選擇與集中企業資源；面對著資訊時代的來臨，投資網路與通訊新事業；隨著全球化的變化，企業不只有著重於日本市場，更以策略聯盟的方式以拓展全球市場。 由於控股公司架構的施行，可以幫助企業易於事業重組與進入新事業、企業轉變成為以策略為重點、權力分配朝向大幅授權與分權自主。就管理制度而言，為了適應mega-competition的競爭環境，反應速度是重要的考量，因此除了維持生產效率之外，經營效率亦是訴求重點。強調創新精神、加速決策過程、採用績效制度、藉助資訊系統等，以搭配控股公司的組織架構，期待能創造出另一波為人稱道的日本式經營。 本研究的結果，正是吾人探索二十一世紀經營之典範。對於台灣企業而言，台灣企業一直和日本企業保持著亦師亦友的角色，日本企業所面臨的大小問題，似乎都是台灣企業未來極有可能遇見的狀況，透過日本企業的深入了解，不但給予台灣企業警惕，也提供台灣企業良好的教材。 / The research studies Japanese firms' changes in face of bubble economy, financial crisis, and globalization as well as digital and service economy. Due to rapid growth in the 1980s, while facing the fast changes of business environment in the past decade, most of Japanese companies suffered from slow responses, insufficient innovation, and over diversified resources. To revitalize the organizations, they are willing to invest in new businesses on the other hand. Because of the lift of pure holding company and reform of consolidated tax system, many Japanese companies are announcing that they will transform themselves to new organizations in form of holding company that had been banned for fifty years. Through the search of three giant general electric firms- Hitachi, Ltd., Toshiba Corporation, and Mitsubishi Electric Corporation, the research discusses how the Japanese enterprises change and how the holding company structure plays in organizational changes. In terms of strategic rethinking, organizational adaptation, and managerial revitalization, Japanese companies are transforming from long term planning to midterm, from manufacturing orientation to service, from diversified resource to selection and focus, and from general electric businesses to network and communications. Not only is Japanese market emphasized, but international markets also are exploited by numbers of global strategic alliances. The introduction of holding company structure helps companies enter new businesses easily, focus efforts on strategies rather than on operations, and delegate more authorities to lower levels. Under the new structure, management system should be changed simultaneously. To survive in new business environment called mega-competition, fast response and managerial efficiency are points. Moreover, entrepreneurship, speedy decision making process, performance-based evaluation, and information system are adopted to fit both strategic rethinking and organizational adaptation. Scrutinizing Japan's adaptation to environment can give Taiwanese companies more understandings of new Japanese business operations. What the research reveals can warn Taiwan of falling into the same path as of Japan.

在當前競爭態勢下，台灣金融市場的發展，勢必朝向跨業經營的方向前進。我國亦於民國九十年六月二十七日通過金融控股公司法，賦予台灣金融業跨業經營的法源，為國內金融業創造成為金融集團的契機，以達成金融跨業經營現代化、國際化的目標。雖然金融機構業務營運多樣化，但金融機構承擔風險亦隨之增加，金融監理機制在面臨這樣的挑戰下勢必得做一番調整，才能持續扮演健全及穩定國內金融體系的重要角色。 我國主管機關對於金融控股公司要求以合併基礎計算資本適足比率，並訂定了「金融控股公司合併資本適足性管理辦法」，以期能發揮適度的監理功能。然該辦法中僅以簡單的加減乘除運算求得之資本適足率，是否為反映集團資本需求的良好指標實不無疑問。因此，本文除了研究國際監理官組織所發布的相關報告外，並藉由介紹和討論歐盟指令對金融集團的補充監理原則和措施，如：資本適足性、集團內部交易、風險集中等問題，以及美國對於金融控股公司之相關監理規範，加以比較研究後，來探討我國現行規範是否妥當，並提出相關監理制度改善之建議，以期能作為我國建構健全金融市場之參考。 / Under current competitive circumstances, the development of Taiwan’s financial market will be bound to move forward in the direction of cross-sector business. In Taiwan, Legislative Yuan also has passed the “Financial Holding Company Act” in June 2001. With the passage of the act, it not only gives Taiwan’s financial institutions authority to operate cross-sector activities, but also creates a trigger for financial institutions to become financial conglomerates in order to meet the objectives of financial modernization and globalization. Although financial institutions may diversify their business, additional risks may arise. Financial regulatory mechanisms have to adjust their function to ensure the safety and soundness of financial system. Our competent authorities demand financial holding companies calculating their capital adequacy ratio on a consolidated basis, and enact “Regulations Governing the Consolidated Capital Adequacy of A Financial Holding Company.” However, in this regulation, the ratio was calculated in simple aggregated method, and it is doubtful that such ratio is a good index to reflect consolidated capital requirement. Therefore, this thesis not only studies on related publications issued by international supervision organizations, but also introduces EU Financial Conglomerate Directive with regard to some supervisory issues (e.g. capital adequacy, intra-group transactions and risk concentrations etc.) and U.S. framework for financial holding company supervision. After investigating and comparing different models, this study tries to find whether current regulation is appropriate or not, and make some suggestions concerning the supervisory system in order to construct a sound financial market as a reference in our country.

綜觀國內外探討金融產業經營效率之相關文獻，多數針對銀行、證券、保險中其一產業進行獨立實證研究，較無法將金融控股之綜效表現加以捕捉並體現在估計效率值中，也因此在本文中，將同時涵蓋銀行業務與證券業務，並以納入金控體制與否加以區分為不同子集合進行探討，透過數理方法聯結金控體制下銀行與證券業務部門兩者間因多角化經營所產生之綜效，以修正傳統方法上表現綜效法上之不足，使估計效率值具有更高的參考依據。 此外，研究產業效率所參考之研究方法，在相關文獻中無參數法乃以資料包絡分析法(Data envelopement analysis, DEA)為多數研究者所採用；參數法則以隨機邊界模型(stochastic frontier approach, SFA)為主要研究方法，進一步在不同群組技術效率之比較中，Battese et al. (2004) 與 O’Donnell et al. (2008)提出為多數研究者所接受之共同邊界模型(Metafrontier)，而Huang et al. (2013)所提出之修正模型使共同邊界模型在效率研究上更加完備，本文則希望以此修正模型作為主要研究模型，並同時引用Battese et al. (2004)傳統模型加以比較：(1)考慮綜效前後 (2)傳統模型與修正模型間效率值的差異，期待為後續相關研究者在方法論上提供參考依據。 關鍵字：經營效率、技術效率、共同邊界、計量方法、關聯結構法、金融控股銀行 / This study aims to discuss the evidence suggested that synergy improve the operating performance of Taiwan’s commerical banks and securites firms. Furthermore, efficiency comparisons amongst two basis metafrontier models, Haung et al.(2013) and Battese et al.(2004), and copula-adjusted metafrontier. The empirical results suggest that copula-adjusted metafrontier could significantly improve the efficiency of financial holding companies based on the data of sample period 2001-2012. On the framework of copula-adjusted metafrontier, the evidence also imply that financial holging companysubsidiary technical efficiency is better than non-financial holding company compared to the framework of Haung et al.(2013) and Battese et al.(2004), the conclusion emphasis that synergy is perhaps one crucial key factor influenced the efficiency estimation. Otherwise, this study appears to support the copula-adjusted metafrontier model is also well-adjusted compared to programming techniques because not only it enables the statistical inferences to be drawn, but also provides more efficiency estimations.

La société holding est une réalité économique dont l’importance ne cesse d’augmenter. Plusieurs États offrent des régimes de faveurs fiscales pour attirer les holdings sur leurs territoires. Le système fiscal turc n’offre pas un tel «régime holding» mais il comporte plusieurs dispositions qui offrent certains avantages aux participations turques et étrangères. Une fiscalité avantageuse pour les holdings est intéressante pour un État dans la mesure où elle lui permet d’attirer les entreprises. Les dispositions fiscales peuvent rendre un territoire attractif et compétitif mais elles peuvent inciter une évasion fiscale à l’intérieur même du territoire. Le second risque engendré par le régime fiscal avantageux est l’établissement d’une concurrence fiscale déloyale. Les éléments clés d’une fiscalité idéale pour la société holding prennent en compte, d’une part la distribution des bénéfices de la holding, et d’autre part, les bénéfices provenant de ses propres participations, notamment les dividendes provenant de ses filiales et les plus-values de cession de ces participations. Par ailleurs, le régime fiscal holding doit être attractif et compétitif tout en restant compatible avec les principes reconnus du droit fiscal international. / The holding company is an economic reality whose importance is still increasing. Several countries offer tax benefits plans to attract holdings in their territories. The Turkish tax system does not offer such a "holding plan" but it contains several provisions that provide certain benefits to Turkish and foreign investments. Tax advantages for holding companies are important for the State to the extent that it attracts businesses and group companies. The tax provisions can make an attractive and competitive territory, yet they may increase tax evasion within the same territory. Another risk caused by the advantageous tax regime is harmful tax competition. The key elements of an ideal tax system of holding companies are about, first of all, the distribution of profits of the holding company and secondly, income from its own shares, including dividends from its subsidiaries and the capital gains disposal of their shares. Furthermore, the holding company tax system must be both competitive and attractive and at the same time it must be compatible with the principles acknowledged by international tax law.

Taxation of permanent establishments is one of the most complicated areas within international tax law. The system of permanent establishment is based not only on the national legislations of relevant states, but also (mainly) on the international double taxation treaties. This diploma thesis analyses those issues in the taxation of permanent establishments, which are the most up-to-date or can be considered as the key questions of the whole concept and therefore can be significant for the future development of the permanent establishments. However the technically perfect system of permanent establishments should come hand in hand with the practical feasibility and overall efficiency. This assumption is nowadays challenged by several trends like the growing popularity of offshore tax heavens or the development of information technologies, which complicate the determination of (fixed) place of business through which the business of an enterprise is wholy or partly carried on. The technical analyses in this thesis are, therefore, supplemented by the objective evaluations from the perspective of valid legislation, possible approaches of the tax authorities, as well as of the enterprise considerations and also the global international taxation picture. This involves also the aspects of tax policies at the level of sovereign states, especially the Czech Republic.
