本研究探討公司治理內外部機制強度對決策者研發和廣告支出裁量權之影響，亦即探討公司治理程度與裁決性支出間之關係。並且探討不同成長機會及規模之公司，其公司治理機制與裁決性支出之關連性。以2001年至2004年為研究期間，樣本為我國上市電子公司。研究結果發現： 1. 在研發支出整體樣本中，董事席位數及會計師查核意見與研發支出呈正向關係，應收關係人款項則與研發支出呈負向關係。 2. 在高成長機會公司樣本中，董事席位數及會計師事務所審計品質與研發支出呈正向關係；應收關係人款項與研發支出呈負相關，與廣告支出則呈正相關。 3. 在大規模公司樣本中，董事長兼任總經理及應收關係人款項與研發支出間以及董監事持股比率及會計師查核意見與廣告支出間皆呈負相關；而會計師事務所審計品質與研發支出則呈正相關。 4. 在小規模公司樣本中，機構投資人持股比率與研發支出呈顯著負相關。 綜合本研究的實證結果發現，公司治理機制對研發支出具有干擾效果，而廣告支出與公司治理間線性相依程度甚低，另高成長機會公司及大規模公司，公司治理機制對其裁決性支出有一定程度之影響。 Prior researches were focused on better corporate governance, but were not considered whether the stronger corporate governance will affect the discretionary power of managers.
