本研究發現博達案發生後，非四大事務所會計師對受查公司簽發繼續經營假設有重大疑慮查核意見之可能性，顯著高於博達案發生之前；但是對四大事務所之會計師而言，此項結果並未達到顯著水準，顯示四大事務所會計師對其客戶簽發繼續經營假設有重大疑慮查核意見之可能性，並未受到博達案之影響，其審計品質較具有一致性。另外，本研究亦發現，相對於博達案發生前之正向關係，博達案發生之後，受查公司資產規模與會計師簽發繼續經營假設有重大疑慮查核意見之可能性呈現顯著負向關係；而當受查公司當年度營業活動現金流量呈現淨流出時，則會提高會計師簽發繼續經營假設有重大疑慮查核意見之可能性。

The purpose of the study is to investigate the effects of the Procomp scandal (2004) on subsequent issuances of qualified audit opinions on the basis of going concern. To ensure the results reflect effects of the scandal on issuances of going concern opinions, this study includes several moderating variables reported in the literature. The empirical results indicate that non-Big 4 firms have issued more going concern audit opinions after the Procomp scandal than before the scandal while there was no significant difference in audit opinions issued by the Big 4 firms before and after the Procomp scandal. The Procomp scandal appears to have no effect on issuing going concern opinions by Big 4 firms, possibly a result of having a more consistent audit quality or having confidence on their audit practices and quality. The results also indicate that clients' assets have a negative relationship with the possibility of issuing going concern opinions after the scandal, compared to a positive relationship before the scandal, and when clients had net negative operating cash flows, more going concern audit opinions were issued by auditors.
