本研究使用固守職位理論(Entrenchment theory)解釋在經理人更替後因風格不同及代理人問題造成繼任者有現金持有動機的轉換，此項交乘效果將造成公司現金持有決策的轉變。同時本研究使用多角化公司的財務決策轉變作為例子，解釋在能力配對理論(Ability-matching theory)中不同公司性質造成CEO更替之後決策轉變的原因。研究結果顯示在兩種理論之下，被強制替換或自動離職的狀況將會帶來經理人風格轉變、前任代理人問題減輕或在公司狀況不同下使得現金持有因素有顯著的增減。然而整體實證結果因增減效果彼此抵消，CEO更替對於現金持有的影響並不顯著。

Our research used entrenchment theory to explain the changing in cash holding after CEO turnover can be caused by different managerial style and agency problem. The interaction of turnover and entrenchment effect will transform motivations of holding cash and further changing the liquidity policy. Meanwhile, we used the ability-matching theory to explain the changing of financial decision in diversified companies to show how different company characteristics affect corporate financial strategy after CEO turnover. Our results showed that based on the two theory, CEO characteristics, agency problem and firm characteristic will significantly affect the financial variables. However, the total effect of CEO turnover on cash holding policy is insignificant because the different effects off set the total effect.
