In the past, most of the literature focused on the impact of Big N accounting firm mergers, while the impact of non-Big N accounting firm mergers is quite limited. This paper is different from the past, through the existing literature of accounting firm mergers, to analyze whether its impact is still used in non-Big N accounting firm mergers. In this study, there are three non-Big N accounting firm mergers, DIWAN merges on June 1, 2009, Crowe Horwath merges on January 1, 2013 and January 1, 2016.And then measure the impact of the mergers on audit fees, discretionary accruals, and stock price reactions. The empirical results indicate that after the mergers of non-Big N accounting firm, there is a significant positive correlation with audit fees. Second, the results show that after the mergers of non-Big N accounting firm, the amount of audit clients discretionary accruals decreased significantly, representing a significant positive correlation with audit quality. However, there was no consistent evidence under investigation that the stock price of the audit clients had significantly positive abnormal returns during the event of mergers case. en_US DC.subject 會計師事務所合併 zh_TW DC.subject 審計公費 zh_TW DC.subject 審計品質 zh_TW DC.subject 裁決性應計數 zh_TW DC.subject 客戶股價反映 zh_TW DC.subject 事件研究法 zh_TW DC.subject accounting firm mergers en_US DC.subject audit fees en_US DC.subject audit quality en_US DC.subject discretionary accruals en_US DC.subject stock price reactions en_US DC.subject Event study en_US DC.title 事務所合併對審計公費、審計品質與客戶股價之影響-以非大型事務所合併案為例 zh_TW dc.language.iso zh-TW zh-TW DC.title The Effect of Accounting Firm Mergers on Audit Fees、Audit Quality and Stock Price Reactions en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
