摘要

實務上普遍存在著初次查核公費折價的疑慮，但最早的研究並沒有發現此情況，而國外學者Simon and Francis (1988) 研究發現：查核最初三年公費有折價的現象，至於台灣審計市場中，由於以往有關台灣市場審計公費的研究，多數資料都是以問卷調查方式取得，造成非常多研究限制，而自從我國主管機關規定自2002年的年報起，符合一定條件下之公開發行公司必須揭露公費資料，以使投資人能夠評估會計師提供非審計服務是否影響其獨立性，因而引發本研究探討審計公費相關議題之動機。再加上審計市場競爭日趨白熱化，更進一步想探討會計師事務所間首次查核訂價以及其查核效率之關聯，探究台灣審計市場實務上是否也存有公費折價的現象。
本研究發現（一）台灣上市（櫃）公司存有首次查核公費折價的現象，且其折價的幅度為18.97%；（二）就整體公費折價迴歸模式而言，影響公費折價的因素，以技術效率此一自變數最具顯著效果，且技術效率變數明確衡量出首次查核效率與審計公費訂價之關聯，實證結果得知，會計師事務所本身成本優劣勢與審計公費折價幅度具有顯著正向關係；（三）就CHGEXP2自變數而言，若改以會計師事務所市場佔有率20%(CHGEXP2a)做為區分產業專家的標準，另外執行敏感度分析，實證結果顯示，以會計師事務所審計市場佔有率超過20%(CHGEXP2a)視為產業專家的迴歸模型，更具統計上的意義。

The practice of discounting on initial audit fee commonly raises public’s concerns, but such a condition has not been found in prior literatures. Simon and Francis (1988) shows that audit fees are often discounted in the first three years’ engagement. For Taiwan, previous studies related to audit fees in the audit market mostly collect their data through questionnaire surveys, which causes a lot of research limitations. As the Taiwan authority requires that from 2002, listed companies under certain conditions are obliged to disclose their audit fees in the annual report, investors are enabled to assess whether the non-audit services provided by auditors have impaired their independence, and this paper is also motivated to explore the related issues on audit fees. In addition, the daily fierce competition in the audit market interests the author to explore further into the relationship between initial audit pricing and auditor efficiency among CPA firms and study whether the practice of discounting on initial audit fee also exists in Taiwan audit market.
The findings show as follows: (1) Initial audit fee discounting is practiced in Taiwan listed companies and with an average range of 18.97 percent. (2) As to the regression model of overall audit fee discounting, technical efficiency is the most important determinant of audit fee discounting, and the technical efficiency variable can explicitly indicates the relationship between initial audit efficiency and audit fee pricing. As the empirical results show, the advantages and disadvantages of an accounting firms’ own cost and the discount range of audit fees have significant positive correlation. (3) As to the independent variable CHGEXP2, a 20 percent market-share of CPA firm (CHGEXP2a) is treated as the classification standard of industry specialist and a sensitivity analysis is performed. As the results show, a regression model that classifies industry specialists by finding CPA firms who have a market share over 20 percent is more statistically meaningful.
