The main purpose of this paper is to investigate the association between corporate governance structure and top executive stock option. The core agency problem is between controlling shareholder and minority shareholders in Taiwan. We expect that poor mechanics of corporate governance will pay more top executive stock option. The empirical evidence shows that when firms are corporate governance with serious agency problem, their payment of stock option with CEO executive are too more. Meanwhile, we find that Ultimate controlling shareholder with deviation of cash rights to voting rights, larger voting rights, high percentage of directors holding and participated in supervisory committee is pay higher stock-based compensation to top executives. Finally, this study exhibits that family-controlled shareholders are more likely to pat more stock option to CEO. Our results suggest that firms with weaker governance structures have greater agency problem and pay greater top executive higher stock-based compensation. Moreover, the firms distributing prior stock bonus generate more current ROE.
