本研究探討雙簽制度下，產業專精對查核任期與會計重編間關係之影響，使用數據 來自於台灣上市櫃公司。現有文獻對於查核任期與盈餘品質間關係並不一致，並存有兩對立觀點，本研究檢驗查核任期與會計重編間關係是否為非線性關係，查核任期超過某一特定門檻後，是否會損害會計師獨立性，增加會計重編機率而傷害盈餘品質，而此非線性關係，是否能透過產業專精解釋。台灣相關法規規定，上市櫃公司財務報導須經二位會計師查核簽證，並於查核報告簽名，共同負連帶保證責任，即「雙簽制度」。本研究以台灣數據特色，將事務所層級產業專精觀點延伸至會計師層級觀點，探討雙簽制度下，查核任期於會計師專業知識水準不同時，對會計重編所造成影響是否不同。預期相較於非產業專家，產業專家之查核任期與會計重編間為更顯著負相關，且主要影響為會計師層級產業專精，更進一步比較主查會計師與副查會計師，預期主查會計師影響力較大。;This study examines the effects of industry specialization on audit tenure and accounting restatements in the Dual Attestation System.
