本研究是為了探討在董事長兼總經理的公司環境下，董監事會特性及審計品質對財務預測準確度的影響，藉以推論董監事會特性及會計師事務所規模抑制管理當局盈餘管理的效果。因為公司治理是需要內、外部控制機制雙頭齊下，才能真正見到成效，故本研究除擷取出董事會規模、外部董監事席次比例、董監事持股比例與董監事持股質押比例做為董監事會特性的變數，另外以事務所規模作為審計品質的衡量方法，加以探討其對財務預測準確度之影響。
其研究結果發現，董監事持股比例對財務準確度有正相關，而董監持股質押比例與審計品質對財務準確度則為負相關，因此本研究推論在董事長兼總經理的環境下，董監持股比例愈高、董監持股質押比例愈低，管理當局發佈的財務預測準確度愈準確，而審計品質愈佳，管理當局發佈的財務預測愈不準確。
