【摘要】： 審計(jì)意見是注冊(cè)會(huì)計(jì)師完成審計(jì)工作的最終成果,我國(guó)的獨(dú)立審計(jì)準(zhǔn)則將審計(jì)意見分為標(biāo)準(zhǔn)無保留意見和非標(biāo)準(zhǔn)無保留意見兩類。本文針對(duì)注冊(cè)會(huì)計(jì)師簽發(fā)審計(jì)意見這一事件對(duì)資本市場(chǎng)的影響作實(shí)證研究,重點(diǎn)探討了資本市場(chǎng)對(duì)非標(biāo)準(zhǔn)無保留意見的反應(yīng),分析投資者得知上市公司被簽發(fā)非標(biāo)準(zhǔn)無保留意見時(shí)對(duì)該公司股價(jià)的反應(yīng)。 本文分析了審計(jì)意見及其與資本市場(chǎng)的關(guān)系,并且對(duì)2000年至2007年中國(guó)上市公司被出具的審計(jì)意見進(jìn)行了描述性統(tǒng)計(jì),分析了其表現(xiàn)出的特證。實(shí)證研究以年報(bào)公布日為事件日,以Mikkelson和Partch的事件分析法為本文的研究方法,研究的觀察期為事件日的前后15天,共計(jì)31天,選取了2005、2006年和2007年年報(bào)中265個(gè)非標(biāo)準(zhǔn)無保留意見作為樣本。通過分析平均累計(jì)異常收益來檢驗(yàn)注冊(cè)會(huì)計(jì)師出具的非標(biāo)準(zhǔn)無保留意見是否對(duì)股票收益有影響。 本文從四個(gè)角度進(jìn)行了實(shí)證研究。首先,檢驗(yàn)不分類型非標(biāo)準(zhǔn)無保留意見的平均累計(jì)異常收益顯著性水平;其次,分別檢驗(yàn)違反會(huì)計(jì)準(zhǔn)則、審計(jì)范圍受限、持續(xù)經(jīng)營(yíng)、強(qiáng)調(diào)其它重大事項(xiàng)的保留四種類型非標(biāo)準(zhǔn)無保留意見的平均累計(jì)異常收益顯著性水平;再次,檢驗(yàn)首次出現(xiàn)非標(biāo)準(zhǔn)無保留意見的平均累計(jì)異常收益顯著性水平;最后,檢驗(yàn)連續(xù)類型非標(biāo)準(zhǔn)無保留意見的平均累計(jì)異常收益顯著性水平。 通過實(shí)證研究發(fā)現(xiàn),當(dāng)非標(biāo)準(zhǔn)無保留意見被簽發(fā)的時(shí)候,具有信息含量存在。雖然不會(huì)立刻對(duì)股價(jià)產(chǎn)生負(fù)面的影響,但是在事件日以后的10天左右股價(jià)會(huì)下降,異常收益水平顯著,說明資本市場(chǎng)對(duì)非標(biāo)準(zhǔn)無保留意見的反應(yīng)比較緩慢。
[Abstract]:The audit opinion is the final result of the audit work completed by CPA. The independent audit standard of our country divides the audit opinion into two categories: standard unqualified opinion and non-standard unqualified opinion.This paper makes an empirical study on the impact of the audit opinion issued by CPA on the capital market, and focuses on the response of the capital market to the non-standard unqualified opinion.Analyze the investors' reaction to the company's stock price when they know that the listed company has been issued a non-standard unqualified opinion.This paper analyzes the audit opinion and its relationship with the capital market, and makes descriptive statistics on the audit opinions issued by Chinese listed companies from 2000 to 2007.The empirical study takes the annual report publication day as the event day, Mikkelson and Partch's event analysis method as the research method, and the observation period is 15 days before and after the event day, a total of 31 days.Selected 265 non-standard unqualified opinions in 2005, 2006 and 2007 annual reports as samples.This paper analyzes the average accumulated abnormal return to test whether the non-standard unqualified opinion issued by CPA has influence on the stock return.This article carries on the empirical research from four angles.First of all, to test the significant level of the average cumulative abnormal income regardless of the type of non-standard unqualified opinion; secondly, to test the accounting standards violated separately, the audit scope is limited, and the business is going on.Emphasizing the significant level of the average cumulative abnormal return of the four types of non-standard unqualified opinions reserved for other material matters; thirdly, testing the significant level of the average cumulative abnormal return of the first non-standard unqualified opinion; finally,Test the significant level of average cumulative abnormal return of continuous type of non-standard unqualified opinion.The empirical results show that there is information content when non-standard unqualified opinions are issued.Although it will not immediately have a negative impact on the stock price, the stock price will fall about 10 days after the event date, and the abnormal return level is significant, indicating that the capital market's response to the non-standard unqualified opinion is relatively slow.
