本文旨在探討集團企業之組織型態差異是否存有不同的盈餘管理行為，並進一步觀察會計師簽證網絡關係之影響。實證發現，在四大之查核樣本中，發現相較於水平整合，垂直整合企業較會使用裁決性應計數進行盈餘向下之管理，且在主簽二階與副簽一階之迴歸結果，也發現垂直整合企業會透過過度生產之方式操作盈餘；在交乘項上，發現主簽簽證網絡能有效抑制垂直整合企業使用應計項目盈餘管理，且在四大查核之樣本中，發現若有較廣之會計師簽證網絡，能讓集團企業會計師充分發揮其查核知識與技能，能更進一步限制垂直整合企業進行過度生產之行為。

This study explores whether different business organizational types exhibit different earnings management behavior and further investigates the effect of auditor signing networks. Empirical results from subsamples of the "Big Four" CPA firms show that compared to horizontal integration, vertically integrated affiliated business groups utilize negative discretionary accruals for downward earnings management. Moreover, regression analysis of the second stage of lead audit partners and the first stage of concurrent audit partners indicates that vertically integrated affiliated business groups use overproduction to manipulate earnings. Observations of the interaction between integration strategies and signing networks of CPAs reveal that lead auditor networks can effectively suppress the use of accrual-based earnings management by vertically integrated groups. Real earnings management results from sub-samples of the Big Four demonstrate that broader signing networks allow affiliated business group audit partners to fully utilize their auditing knowledge and skills to limit a company's overproduction behavior.
