本研究利用複迴歸模型與追蹤資料模型，透過子公司市佔率探討金控子公司組合，與公司績效及風險之關聯性，期望能找出何種子公司組合，對於金控公司的績效與風險最有影響。依據2002-2015之季資料，本文主要研究結果如下： (一)若以全產業角度而言，壽險業、證券業與票券業市佔率，對於金控績效與風險影響較為顯著。壽險業市佔率增加，會提高金控之系統風險與個別風險，而證券業市佔率增加，會提高金控的總風險、系統風險與個別風險。本研究推測主要原因為壽險業與證券業的產業風險較高，容易影響金控之經營風險，故有此現象。 (二)金控若採用雙引擎策略，可以降低金控之總風險與系統風險，亦即雙引擎策略對金控之風險經營有穩健的效果。 (三)以銀行業與壽險業組合為探討對象時，則發現銀行業市佔率提高，可能使金控之破產風險上升，而壽險業的市佔率提高，金控之總風險與系統風險亦會提升。此結果顯示銀行與壽險業的子公司組合無法有效改善金控之風險因子。 (四)以銀行業與產險業組合為探討對象時，則發現銀行市佔率提升，可能使金控之各項風險因子增加，並且會降低風險調整後的報酬。而產險業市佔率增加，則會降低金控績效，並提高金控之破產風險。 (五)以銀行業與證券業組合為探討對象時，則發現證券業市佔率增加，僅會顯著增加金控之個別風險。 (六)以銀行業與票券業組合為探討對象時，則發現銀行業市佔率增加，可能使金控之績效下降，並提高金控之破產風險，然而若票券業市佔率提高，反而會增加金控之經營績效，並降低破產風險。 / This study analyzes the effect of the subsidiary combination and market share on the performance and risk of financial holding companies (FHCs). Based on the data of 2002Q1-2015Q4, the empirical result can be summarized as follows. 1. From the viewpoint of the whole industry, there is a significant relation between the market share of the subsidiaries and the performance and risk of FHCs. The result shows there is a positive effect of life insurance market share on systematic risk and idiosyncratic risk. And there is a positive effect of securities market share on total risk, systematic risk and idiosyncratic risk. 2. FHCs can reduce their total risk and systematic risk by taking dual-engine strategy. The result shows that dual-engine strategy is a sound strategy for FHCs’ operation. 3. For the subsidiary combination of bank and life insurer, there is a positive relation between bank market share and insolvency risk. And there is a positive relation among life insurance market share, total risk and systematic risk. 4. For the subsidiary combination of bank and property insurer, there is a positive relation among bank market share and FHCs’ risk. And there is a negative relation between property insurance market share and FHCs’ performance. 5. For the subsidiary combination of bank and securities company, there is a positive relation between securities market share and idiosyncratic risk. 6. For the subsidiary combination of bank and bills company, the increase of bank market share is unfavorable for FHCs’ operation, but the increase of bills company is beneficial for FHCs’ operation.

我國國立高級中等學校實施校務基金之目的除了提升績效外，尚期以增進各校自籌財源之動力，以減輕政府財政負擔，自2007年起開始實施校務基金後之績效為何?值得進一步探討。 本研究係以資料包絡分析法評估各國立高級中等學校2010年至2012年的經營績效，並運用麥氏指數衡量其跨期效率變動情形，最後以Tobit迴歸分析，探討外在環境變數對校務基金實施績效之影響。實證研究結果如下： 一、總技術效率分析：2010、2011及2012年平均總技術效率值依序為0.712、0.714、0.705，表示各該年度尚有28.8%、28.6%及29.5%的效率改善空間。若將各國立高級中等學校依照類別區分，普通高中平均總技術效率表現最佳，綜合高中的表現比職業學校佳，特教學校最差。 二、純技術效率分析：2010、2011及2012年平均純技術效率值依序為0.768、0.781、0.771，表示各該年度尚有23.2%、21.9%及22.9%的效率改善空間。普通高中平均純效率表現最佳，綜合高中的表現比職業學校佳，特教學校最差。 三、規模效率分析：2010、2011及2012年平均規模效率值依序為0.923、 0.908、0.908，表示各該年度尚有7.7%、9.2%及9.2%的效率改善空間。2010年以職業學校表現最佳，2011年以綜合高中表現最佳，2012年度以普通高中表現最佳。特教學校在三個年度的平均規模效率均為最差。 四、麥氏指數分析：2010至2012年度之總要素生產力變動值均小於1，呈現衰退現象， 2010至2011年度及2011至2012年度二個跨期均呈現衰退。 五、Tobit迴歸分析：除實施校務基金的年限無顯著影響外，學校區位、校舍面積及學校成立年限等三項外在環境對學校的經營績效均具有影響。 / The purpose of national senior high schools in Taiwan implementing National Senior High Schools Operation Fund is not only improving performance, but also enhancing the schools’ self-motivation of the financial resources to reduce the fiscal burden of government. How is the performance of implementing National Senior High Schools Operation Fund since 2007?It is worthy of further study. This study is based on Data Envelopment Analysis to evaluate the operating performance of national senior high schools from 2010 to 2012. In addition, this study uses Malmquist Index to measure the efficiency changes. Finally, Tobit regression analysis is used and tried to find effects of the external environment variables on the implemenetation performance of National Senior High Schools Operation Fund. The findings of this study are as follows: 1.Overall technical efficiency analysis：the average value of the overall technical efficiency is 0.712、0.714、0.705 in sequence of year 2010、2011 and 2012, and it means that the efficiency improvement is 28.8%, 28.6% and 29.5% each year. If we evaluate the performance of national senior high schools by category, the general high schools are the best, the comprehensive high schools are better than vocational high schools, and the special education schools are the worst. 2.Pure technical efficiency analysis.：the average value of the pure technical efficiency is 0.768、0.781、0.771 in sequence of year 2010、2011 and 2012, and it means that the efficiency improvement is 23.2%、21.9% and 22.9% each year. The general senior high schools are the best, the comprehensive senior high schools are better than vocational senior high schools, and the special education schools are the worst. 3.Scale efficiency analysis: the average value of the scale efficiency is 0.923、 0.908、0.908 in sequence of year 2010、2011 and 2012,and it means that the efficiency improvement is 7.7%、9.2% and 9.2% each year. The best performance is the vocational senior high schools in 2010, the comprehensive senior high schools in 2011, and the general senior high schools in 2012, the special education schools are the worst in all three years. 4.Malmquist Index analysis: the value of the total factor productivity change is totally less than 1 from 2010 to 2012, and shows the recession .And the inter-temporal total factor productivity changes show the recession from 2010 to 2011, and 2011 to 2012. 5.Tobit regression analysis: there is no significant impact in the factor of the years of the National Senior High Schools Operation Fund, but the external factors such as the size, the history, and the location of the schools, would affect the performance of national senior high schools.

建構一套健全的公司治理評等機制，為落實公司治理相關議題的核心工作。本研究以經濟暨合作發展組織之公司治理原則、世界銀行之公司治理架構與國內外公司治理相關實證文獻作為理論基礎，透過分析量化之公司層級衡量指標，嘗試建構一套可行且適合衡量台灣企業之公司治理評等指標，以作為投資人制定投資決策與授信機構評估企業債信風險時之參考。 本研究以2002年國內523家非金融業上市公司為樣本，利用LISREL方法 (線性結構關係模式統計方法)建構台灣公司治理評等指標。分析結果共得出：股權結構構面 (盈餘股份比、專業機構投資者持股率)；董事會職責構面 (盈餘席次比、外部董事席次比率、外部監察人席次數與外部董監持股率)；財務透明度構面 (盈餘管理幅度、損益平穩化程度與財報重編率)等3個構面、9項衡量指標。 透過與企業當期及次期經營績效、公司價值與投資人投資風險間之關聯性實證測試，本研究發現，前項公司治理評等指標與企業之經營績效、公司價值呈顯著正相關，而與投資人投資風險呈顯著負相關。此項實證結果一方面顯示，前項公司治理評等指標愈佳，企業當期與次期之經營績效與公司價值愈高，投資人之投資風險愈低；另方面亦表示本研究所建構之公司治理評等指標對於企業之經營績效、公司價值與投資人投資風險，具有一定程度之關聯性與預測能力。 / A well-developed corporate governance ranking system is essential to implantation of corporate governance. Base on principles proposed by OECD, a framework provided by the World-Bank and empirical literature on corporate governance, this research attempts to develop a workable TCGI (herein Taiwan Corporate Governance Index or TCGI) ranking system. The purpose of provision of TCGI is to help investors and creditors to make better decisions. Using data for 523 non-banking corporations publicly traded at Taiwan Stock Exchange in 2002, and LISREL as the analytical tool, this research constructs a three-aspect (including ownership structure, responsibility of the board and financial transparency) TCGI ranking system with 9 corresponding indicators in total. The empirical results of association tests show that TCGI indicators are significantly and positively (negatively) related to operation performance and market value (the occurrence of firms encountering financial difficulties). The findings thus imply that the TCGI ranking system developed in this research may be useful in investors and creditors decision-making.
