摘要

當企業面臨各種危機時，不同的危機管理指導原則將會給企業帶來截然不同的後果。企業管理當局因憂心經營績效未達到目標而導致股價下跌，大多會採取盈餘管理的動作來操作盈餘數字，使得財務報表被窗飾及美化。
運用財務比率來預測企業經營績效預警模式不斷地在進化，公司治理有助於建全企業之經營及追求股東最大利益，因此建全公司內部控制制度、強化資訊公開透明度、建立獨立董監事制度，期能更客觀輔助財務指標之衡量。
本研究以公司治理為出發點，並有鑑歷年來企業舞弊案層出不窮，因此，本研究以公司股價變動率為衡量公司價值之指標，探討股權結構、董事會品質、董監事特質及管理架構對公司股價之影響。
以2011年至2015年之台灣證券交易所期間內曾全額交割及股票管理之公司為研究對象，以迴歸模式進行分析。實證結果顯示，當經營權與所有權合一時，在個人的自利動機下，董事長兼任總經理則董事會品質較差，管理當局盈餘分配操緃的程度愈大。

We are taking the samples of cross sectional firms from various industries in Taiwan as the study subject.
