For the multi-purposes of professional management, diversifying investment risk, implementing asset allocation, and increasing investment profit, Labor Pension Fund undertook domestic discretionary operation on Aug. 21, 2007 at first time. As the size of Labor Pension Fund increases rapidly, the mandated percentage of the assets allocation of Labor Pension Fund gets higher year by year. In this study, we investigate the factors that may influence the effectiveness of the discretionary investment of Labor Pension Fund. Our sample data is monthly, dated from Oct. 2007 to Jun. 2013. We estimate with Panel Data Model, investment trust enterprises, fund managers and investment strategy aspects to measure the discretionary investment of LPF. Our major empirical findings are as follows: 1. Investment trust enterprises：Inventors trust larger size, can gain economies of scale efficiency, enhance performance. However the larger the scale of investment trust is, the more easier to bring administrative jobs negligence. The punished number of investment trust enterprises is positively correlated with Jensen ratio, Sharp ratio and portfolio returns and returns TAIEX gap, i.e. three performance indicators, respectively. 2. Fund Managers：The fund managers’ seniority and turnover are negatively correlated with Jnsen ratio. It suggests that LPF investment contract may include specification of the manager during operation of the restrictions and replacements. 3. Investment Strategy：β coefficient is negatively correlated with the returns of investment portfolio, Jensen ratio and Sharp ratio, respectively. It suggests that LPF and fund manager should comply with the principles of security and steadiness. Buying turnover rate is positively correlated with the returns of investment portfolio, jensen ratio and sharp ratio, respectively. Selling turnover rate is negatively correlated with the returns of investment portfolio, and is positively correlated with portfolio returns and returns TAIEX gap. Our empirical findings show that the turnover rate can improve the investment performance, while it also increases the transaction cost.CONTENTS 摘要 i ABSTRACT ii CONTENTS iv 表目錄 vi 圖目錄 vii 第一章 緒論 1 1.1 研究背景 1 1.2 研究目的 4 1.3 研究方法與限制 6 1.3.1 研究方法 6 1.3.2 研究限制 6 1.4 研究架構 7 1.5 研究流程 8 第二章 勞工退休基金與委託經營 9 2.1 勞工退休基金監理會 9 2.2 勞工退休基金介紹及業務 11 2.2.1 新舊制基金制度說明 11 2.2.2 新舊制基金投資運用範圍 14 2.3 新制勞工退休基金業務概況 17 2.4 新制勞工退休基金國內委託經營現況 19 2.4.1 委託經營概述 19 2.4.2 勞退基金全權委託投資作業流程 20 2.5 新制勞退國內委託經營現況 22 2.6 勞工退休基金委託經營制度的問題 25 第三章 文獻探討 27 3.1 委託經營所產生代理問題之相關文獻 27 3.2 基金績效衡量指標 31 3.3 影響基金績效因素相關文獻 34 3.3.1 國內文獻 34 3.3.2 國外文獻 36 第四章 實證模型設定與樣本資料 40 4.1 資料來源與樣本定義 40 4.2 樣本資料處理 44 4.3 計量方法與步驟 46 4.3.1 混合迴歸模型（Pooled Regression Model） 46 4.3.2 固定效果模型(Fixed Effect Model) 47 4.3.3 隨機效果模型(Random Effect Model) 48 第五章 實證結果與分析 50 5.1 敘述統計量 50 5.2 迴歸模型檢定 52 第六章 結論與建議 58 6.1 結論 58 6.2 建議 59 參考文獻 61 附錄 65591612 bytesapplication/pdf論文使用權限：不同意授權勞退基金委託經營績效橫斷面時間序列分析法thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/263375/1/ntu-102-P00323008-1.pdf
