中國的開放式基金近年來高速發展，對中國資本市場的影響與日俱增。然而目前在中國境內對基金所採用的基金績效評價方法仍為較為傳統的方法，如夏普比率、特雷納指數等。而傳統的基金績效評價方法未能很好地顯示基金的真實績效情況。鑒於美國基金有較為先進的績效評價方法，本文利用DEA數據包分析法模型，構建一個包括從基金期初規模、風險收益情況、基金經理人能力及投資人風險偏好等多方面因素的基金績效評價體系。 本研究選擇中國181檔股票型開放式基金，從基金規模及投資風格兩個維度展開深入研究分析。此外，為比較交易量不同期間基金績效的表現情況，本研究依照深證、滬證市場交易量、交易額，將2012年至2015年此段實證期劃分為交易活躍期及交易低迷期兩個階段，對基金績效進行比較分析。結果顯示，交易活躍期的基金績效遠高於交易低迷期；並且無論是交易活躍期或是交易低迷期，小型基金及主動型基金績效表現最佳；而基金的相對績效情況於其基金管理人的資產規模並無顯著相關關係。 在文章最後部分，本文從投資人角度建議投資人在證券市場交易活躍期可增加股票型基金的投資額度，在基金選擇上無需盲目傾向選擇大公司的基金產品，而可以適當傾向投資於小型基金及主動型基金。 / With the rapid development of mutual funds in China in the past decades, open-ended funds have played an important role in Chinese capital markets. To overcome the limitations of traditional performance measurements, this paper establishes a new methodology to analyze open-ended mutual fund performance. This paper uses data development analysis model which considers asset size, risk return, managers’ ability and risk performance of the investors. By utilizing 181 open-ended stock fund data from 2012 to 2015, this paper yields conclusions as follows. First, fund performance is better in strong market periods than that in weak market periods. Second, small size and active funds are more efficient. Third, fund performance is not significant associated with fund asset size and fund units in the fund company. The findings in this paper suggest that investors could do more investment on the open-ended stock funds in the strong market periods. And investors are suggested to invest small size and active fund. What’s more, there is no necessary to consider if the fund’s management company is big enough.

隨著台海兩岸經貿往來密切，發展迅速，客觀上對銀行業提出了許多服務要求，為兩岸金融業的合作提供了廣闊的空間。本文通過採用數據包絡分析法和共同邊界成本函數比較分析了兩岸商業銀行的成本結構及效率差異，實證結果表示大陸商業銀行的成本效率要高於台灣銀行。對這一結果的可能性解釋是大陸銀行的資產規模要遠高於台灣銀行。銀行總資產越高，其獲取低投入要素價格的市場能力越強，因此生產成本更低，成本效率更高。台灣和大陸商業銀行有必要發揮自身的優勢，通過各種方式和渠道，加快兩岸銀行界合作的進程。 / With cross-strait rapid economic development and trade exchanges, huge business investments have induced a great demand for financial services and provided a broad space for cross-strait cooperation. This paper adopts data envelopment analysis and meta-frontier cost function to compare and analyze the different cost structure and efficiency of mainland and Taiwan commercial banks. The empirical results reveal that cost efficiency of mainland commercial banks is higher than Taiwanese ones, which is maybe caused by the larger bank size and total assets. The larger the size of banks, the higher the market power for reaping the benefits of low input prices, thereby resulting in a lower cost of production and a higher cost efficiency. It is necessary for mainland and Taiwan commercial banks to develop their own strengths to accelerate the process of cross-strait cooperation in the banking sector through various means and channels.

中國自改革開放以來，財政體系歷經了幾次重大的變革，其中財政分權為一個重要的階段，並且也被認為是促進中國經濟快速發展的關鍵因素之一。但中央將權力下放給地方，是否對地方政府效率造成正面的效益，許多文獻對此議題有著兩面的看法。因此，本文的研究目的主要探討中國財政分權對地方政府效率的影響。 首先，本研究採用DEA衡量中國31個省市的地方政府效率，並以財政收入的自主性衡量財政分權程度。接著，利用中國的省級追蹤資料（panel data），以及Tobit迴歸模型來進行實證分析。其實證結果指出，財政地方分權和地方政府效率之間存在非線性的關係，意即存在一個財政分權的臨界值。而其他解釋變數方面，各省市人口密度和人均實質GDP對地方政府效率為顯著且正面的影響。此外，時間趨勢變數對地方政府效率存在著顯著且負向的效果。 / The purpose of this study is to investigate the effect of fiscal decentralization on the efficiency of local governments in China. Fisrst, this study uses the data envelopment analysis to weigh the efficiency of local governments in China, and takes revenue-autonomy to the variable of finance decentralization. Then, by using the panel data in 31 regions during the period of 1996-2008, this study adopts the Tobit model to analyze whether or not the fiscal decentralization provides a non-linear effect on the local government’s efficiency. The empirical result explain why past papers have inconstant conclusions to this problem and provides some important policy implications.
