This thesis first applies the event study analysis method to examine the impacts and the restorations of the operating incomes of the 15 firms of the textile industries in Taiwan after the impact of the 2008 U.S. subprime financial crisis. Then the firms are categorized into two groups based on four different shareholder structures to compare the capabilities of coping with the adverse external impact. The empirical event studies have shown that firms characterized with syndicate and diversification performed better and that groups with higher proportions of shares held by the board members performed better than those with lower proportions of shareholdings. On the contrary, firms with lower proportions of shares in the hand of the top ten largest shareholders and those with lower proportions of shares held by the domestic institute investor and the foreign institute investors performed better.
