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.

由於國內金融（包括銀行、保險、證券商等）家數過度膨脹，形成惡性競爭，導致金融服務品質低落，而且獲利式微，面對金融市場自由化與國際化之趨勢，政府為改革金融體制，引進金融控股公司制度，使金融機構跨業經營機制更具規模，滿足顧客得一次購足金融商品，促使金融機構朝大型化發展，發揮金融綜效與規模經濟，以提升國際競爭力。 本文主題「論金融控股公司保險子公司之經營策略與內部稽核」，理論與實務並行探討，先論述控股公司之相關法律問題、金融控股公司之立法例。其次以「五力分析術」探討保險子公司經營環境之優劣勢及風險，提出創新之經營策略，並實例引證美國花旗集團異業聯盟之成功經營策略。為確保投資大眾及保戶之權益，同步探討公司治理制度及內部稽核制度之重要性。 本文「結論」：評述政府金融政策之缺失，成立金融控股公司推動金融改革，保險子公司應強化競爭力。「建議」：金融控股公司及各子公司均應加強風險管理，政府並應建置金融監理制度。 關鍵字：保險子公司、金融改革、控股公司、金融控股公司、跨業經營、一次購足商品、金融綜效、規模經濟、五力分析術、異業聯盟、公司治理、內部稽核、風險管理、金融監理 / Due to the over-supply and severe competition among financial institutions (namely banks, insurance companies and security firms), the quality of finance service deteriorates and the profit margin of financial industries decreases. To cope with the global trend of liberalization and internationalization of financial services, the Government has undertaken the reform in the aspect of financial service system and enacted the “Financial Holding Company Act”. Under new current mechanism, a financial conglomerate can sell its products by means of cross selling. Not only it may benefit consumers with a “one-stop shopping”, but also may create a synergy in economies of scale to enhance financial institutions in global competition. The main theme of this thesis focuses on the managerial strategy and internal auditing in an insurance subsidiary under a financial holding company. It addresses in the first place the legal issues related to a holding company and a financial holding company. Then the author adopts five factors approach to analyze the business environment of an insurance subsidiary under a financial holding company. As a successful case for its' strategic alliance,the CitiGroup experience in the United States is also examined. In addition, to protect the interest of investors and policyholders, corporate governance and internal auditing issue is also explored. In the conclusion, it is observed that under the new era of financial conglomeration, an insurance subsidiary still needs to enhance its competition ability. It is suggested that the government should continue to reform the financial regulatory system and to require financial holding companies and their subsidiaries to implement a comprehensive risk management.
