面對接踵而來大型企業財務報表舞弊事件,會計師所出具的查核報告中,卻未明確指出財務報表中含有重大誤述或隱匿情形,導致社會大眾對於會計師之獨立性有所質疑,投資人亦對公司財務報表品質失去信心。故本文探討在資本市場中,是否經由具有外部監督機制的會計師所提供之審計服務,能讓資金提供者更相信財務資訊,以減低代理成本。 本研究以有發佈自結盈餘的企業做為樣本觀察值,以產業審計專家作為衡量審計品質的代理變數,主張產業審計專家具有較佳的查核技術與獨立性,經由查核品質的提昇能有效降低代理關係間之利益衝突,衡量是否較佳的審計品質能降低資金成本;更進一步以自結盈餘和公告盈餘差異衡量可信度,自結盈餘係由管理當局自行結算,而公告盈餘則是由會計師查核後之結果,二者之間的差異可衡量會計師與管理當局認知上的差距,探討財務報表可信度對資金成本的影響。 實證結果顯示經由產業審計專家查核之公司,資金提供者認同其擁有對該產業之專業查核技術,因此給予其所查核的公司較高的評價,故由產業審計專家查核的公司,其資金成本較低;可信度部份結果顯示,當公司自結盈餘和公告盈餘差異愈小,資金提供者認為管理當局事先編製之財務報表盈餘品質較佳,有較高的可信度,其所需承擔的違約風險相對較低,故財務報表可信度愈高,其資金成本愈低。
Facing the Major industry financial reporting to corrupting practices matter ensued, in accountant’s report, there was no clear indication in the financial reporting to include significant states or the concealment situation by mistake, causes the people to question the accountant’s independence, the investor also loses the confidence to the company’s financial statement quality.
