This thesis first applies the event study analysis method to examine the impacts and the restorations of the operating incomes of the 17 firms of the exporting 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 that continue upgrading their production process or extend their business in other areas performed better and those groups with higher proportions of shareholdings by the board members performed better than those with lower proportions of shareholdings. On the contrary, firms with lower proportions of shares in the hands of the top ten largest shareholders and those with lower proportions of shareholdings by the domestic institute investor and foreign institute investors performed better.
