本研究首先從經營績效、公司特性及公司治理角度探討財務主管之異動行為，並分析財務主管異動與後續經營績效及財務危機之關聯性。相關實證結果發現，前期經營績效不佳與內部治理愈差之公司會傾向更動財務主管，且當公司經營績效及財務狀況逐期惡化時，財務主管異動會較頻繁，但未發現控股結構複雜度與財務主管異動有關。此外，財務主管異動後之公司經營績效並無改善之跡象，符合惡性循環假說。財務主管異動與財務危機之研究結果發現，財務主管異動頻率與財務危機呈正向關係惟並不顯著，但若以下市或全額交割定義財務危機時，實證結果顯示，財務主管異動較頻繁、公司內部治理較差之公司，發生下市或全額交割之可能性愈高。 / This thesis examines the determinants of chief financial officer (CFO) turnover behavior and whether CFO turnover signals the operating performance of subsequent period. In addition, the association between CFO turnover and financial distress is also investigated. The empirical findings show that CFOs of firms with poor operating performance and weak internal governance environment are more likely to have turnovers. Deterioration in operating performance and financial conditions leads increase in frequency of the CFO turnover. Moreover, the CFO turnover tends to precede a poorer subsequent operating performance. While there is no association between the frequency of CFO turnover and occurrence of financial distress, it is found that higher the frequency of CFO turnover and poorer the internal governance environment, higher the probability of delisting of firms.
