【摘要】：權益資本成本是企業(yè)通過發(fā)行股票獲得資金而付出的代價,同時也是投資者要求的必要報酬。因此,權益資本成本的高低不論是對企業(yè)還是對投資者都至關重要。通過發(fā)行股票進行股權融資具有融資規(guī)模大、融資約束小、財務風險小的優(yōu)點,因而在實務中被眾多企業(yè)所偏好。在理論研究中,權益資本成本的影響因素眾多,內(nèi)部因素包括公司規(guī)模、產(chǎn)權性質(zhì)、經(jīng)營及財務風險、盈利能力、股票流動性等,外部因素包括系統(tǒng)風險因素、行業(yè)因素、市場監(jiān)管因素等。會計師事務所獨立審計制度是資本市場中進行市場監(jiān)管的重要力量,因而是影響權益資本成本的重要外部制度因素。本文研究思路是從高審計質(zhì)量具有增強上市公司會計信息質(zhì)量、降低投資風險的信息價值出發(fā),結合信息相關理論,提出會計師事務所審計質(zhì)量的提高具有降低上市公司權益資本成本作用的假設,并進一步從產(chǎn)權性質(zhì)、公司規(guī)模兩個維度,基于不同產(chǎn)權性質(zhì)和規(guī)模的上市公司在經(jīng)營目標、公司治理、融資約束、破產(chǎn)風險等方面的差異性,探討這些差異對于審計質(zhì)量降低權益資本成本作用的影響。文章使用實證研究方法,選取2012-2015年我國A股上市的393家公司為研究樣本,采用預測約束較少的OJ模型測算權益資本成本,采用盈余質(zhì)量和會計師事務所規(guī)模兩個指標共同衡量審計質(zhì)量,對本文的研究觀點進行實證檢驗。通過理論分析和實證檢驗,得出本文的研究結論:第一,會計師事務所審計質(zhì)量的提高可以降低上市公司的權益資本成本,這說明會計師事務所獨立審計制度在資本市場中的信息鑒證和監(jiān)督作用得到了有效發(fā)揮,獨立審計具有經(jīng)濟價值;第二,較國有控股上市公司,提高審計質(zhì)量對權益資本成本的降低作用在非國有控股上市公司中發(fā)揮的作用更大;較大規(guī)模公司,提高審計質(zhì)量對權益資本成本的降低作用在小規(guī)模公司中發(fā)揮的作用更大。本文的研究豐富了權益資本成本影響因素的研究文獻,同時將資本市場與審計市場聯(lián)系在一起,對于會計師事務所審計地位的提升,審計質(zhì)量的提高,審計質(zhì)量標準的建立都具有積極的意義。
[Abstract]:The cost of equity capital is the enterprise through the issuance of shares to obtain funds and pay necessary remuneration, but also the requirements of investors. Therefore, the cost of equity capital or whether on business or for investors is crucial.
