2004年可以說是我國的金控元年，而這樣的現象也對我國金融產業的整體環境與原有的金融產業市佔率造成巨大的改變，也使得我國的金融產業跨入一個新紀元。
然而，2008年全球金融風暴越演越烈之際，我國的股市加權指數也伴隨著各國不斷重挫的股市一路下滑至4000點。也因此，不論是對政策制定者或者是投資者來說，金控制度是否能降低系統性風險並為我國本土其餘產業提供穩定的資金，都勢必成為探討財務績效外一個非常重要的議題。
而本研究主要目為探討金控制度對於國外股市與我國金融產業股市關聯性影響。
本研究指出台灣金融產業股價指數與道瓊工業指數、S&P500指數的關聯性受到實施金控制度的影響而減弱，而在歐洲與亞洲股市方面，只有與HIS的關聯性受到影響。此外，本研究也發現不同的金控經營主體的確會為其股價與國外股市的關聯性帶來不同影響。

2004 was the first year that financial holding corporation systems were operating in Taiwan. This event caused the entire finance environment and the market share rates in the financial industry to change acutely; moreover, it led the financial industry into a new era.
However, the Taiwan stock market index has declined continuously down to 4000 as a result of the global stock market financial crisis that started in 2008. It lead that financial holding corporation systems can reduce system-risks, but financial performance been an important issue for both policies makers and investors.
In this research, we discuss the impact of financial holding corporation systems on the correlation between Taiwanese financial industry stock prices and foreign countries.
This research mention the correlation between stock price of Taiwanese financial industry and American stock markets, including the Dow Jones Industrial Average (IDNU) and the S&P 500, is affected by the impact of financial holding corporation system processes. However, there are no influences on Asian and European stock markets but HIS. Moreover, we find the impacts are different accompanying the different main businesses operating individually
