本研究在於探討台灣上市櫃公司的公司治理特徵與盈餘穩健性之關聯性，並以C-Score衡量。本研究係以臺灣2009年至2012年之上市櫃公司為研究對象，盈餘穩健性是採用C-Score
衡量個別企業年度穩健性。
實證結果顯示，CEO雙重性、獨立董事比率、經理人持股比率、董事持股比率以及大股東持股比率與盈餘穩健性呈現顯著負相關。董事會規模以及偏離程度與盈餘穩健性呈現顯著正相關。董事持股比率與家族企業的交乘項對盈餘穩健性呈現顯著正相關。實證結果說明，董事會專業能力強，監督效率高，因此管理階層不易支配董事會，同時股東也越有誘因去監督公司的管理階層，使得盈餘穩健性上升。當管理階層持股比率越高時，基於自我利益和鞏固自身權利的動機之下，管理階層會
過度的操弄盈餘，降低公司績效，使盈餘不具穩健性。
