This paper attempts to inspect the relationship between Chief Executive Officer (CEO) share-holding and the financing decisions in Taiwanese stock-listed company. In this paper, we firstly separate the samples into two groups based on the 25% share-holding ratio of insider. Then, we use ANOVA, ANCOVA, time series cross section regression methods to testify the difference between above two groups from the aspects of debt ratio, current ratio, interest coverage ratio and dividend payout ratio. And we use the above results to discuss whether the phenomena of agency problems have existed in Taiwan or not. Because the ratio of the insider-owned company in Taiwanese stock-listed company has approached above one-half, therefore the empirical result reveals that the influence of agency problem on the financing decisions of corporation is not so significantly.
