審計(jì)師變更與審計(jì)質(zhì)量基于簽字注冊(cè)會(huì)計(jì)師未變更的經(jīng)驗(yàn)證據(jù)一、本文概述Overviewofthisarticle本文旨在探討審計(jì)師變更與審計(jì)質(zhì)量之間的關(guān)系，特別是基于簽字注冊(cè)會(huì)計(jì)師未變更的經(jīng)驗(yàn)證據(jù)。審計(jì)師變更是公司治理結(jié)構(gòu)中的一個(gè)重要環(huán)節(jié)，其背后的動(dòng)因可能涉及多個(gè)方面，如事務(wù)所間的競(jìng)爭(zhēng)、客戶需求的變化、審計(jì)質(zhì)量的要求等。然而，簽字注冊(cè)會(huì)計(jì)師未變更的情況下，審計(jì)師變更是否會(huì)影響審計(jì)質(zhì)量，這一問(wèn)題在學(xué)術(shù)界和實(shí)務(wù)界都存在廣泛的爭(zhēng)議。Thisarticleaimstoexploretherelationshipbetweenauditorchangesandauditquality,especiallybasedonempiricalevidenceofsignedcertifiedpublicaccountantsnotchanging.Auditorchangeisanimportantlinkincorporategovernancestructure,anditsunderlyingfactorsmayinvolvemultipleaspects,suchascompetitionbetweenfirms,changesincustomerneeds,andrequirementsforauditquality.However,thereiswidespreadcontroversyinbothacademicandpracticalcirclesoverwhetherthechangeofauditorwillaffectauditqualitywithoutthechangeofregisteredaccountant.本文首先對(duì)審計(jì)師變更和審計(jì)質(zhì)量的相關(guān)理論進(jìn)行梳理，明確審計(jì)師變更的定義、分類及其對(duì)審計(jì)質(zhì)量可能產(chǎn)生的影響。在此基礎(chǔ)上，本文利用簽字注冊(cè)會(huì)計(jì)師未變更的經(jīng)驗(yàn)證據(jù)，通過(guò)實(shí)證研究方法，深入剖析審計(jì)師變更與審計(jì)質(zhì)量之間的內(nèi)在聯(lián)系。通過(guò)收集相關(guān)數(shù)據(jù)，建立合適的計(jì)量模型，本文旨在揭示簽字注冊(cè)會(huì)計(jì)師未變更的情況下，審計(jì)師變更對(duì)審計(jì)質(zhì)量的具體影響及其作用機(jī)制。Thisarticlefirstreviewstherelevanttheoriesofauditorchangeandauditquality,clarifiesthedefinition,classification,andpossibleimpactofauditorchangeonauditquality.Onthisbasis,thisarticleusesempiricalresearchmethodstodeeplyanalyzetheinherentrelationshipbetweenauditorchangesandauditquality,basedontheempiricalevidenceofunchangedsignedcertifiedpublicaccountants.Bycollectingrelevantdataandestablishingasuitableeconometricmodel,thisarticleaimstorevealthespecificimpactandmechanismofauditorchangesonauditqualityintheabsenceofchangesinthesigningregisteredaccountant.本文的研究具有重要的理論和實(shí)踐意義。從理論層面來(lái)看，本文有助于豐富和完善審計(jì)師變更與審計(jì)質(zhì)量關(guān)系的理論體系，為相關(guān)領(lǐng)域的研究提供新的視角和思路。從實(shí)踐層面來(lái)看，本文的研究結(jié)果可以為監(jiān)管機(jī)構(gòu)、上市公司和審計(jì)機(jī)構(gòu)等提供有益的參考，有助于指導(dǎo)他們?cè)趯?shí)踐中更好地理解和應(yīng)對(duì)審計(jì)師變更對(duì)審計(jì)質(zhì)量的影響，從而提高審計(jì)質(zhì)量，保護(hù)投資者利益，促進(jìn)資本市場(chǎng)的健康發(fā)展。Theresearchinthisarticlehasimportanttheoreticalandpracticalsignificance.Fromatheoreticalperspective,thisarticlehelpstoenrichandimprovethetheoreticalsystemoftherelationshipbetweenauditorchangesandauditquality,providingnewperspectivesandideasforresearchinrelatedfields.Fromapracticalperspective,theresearchfindingsofthisarticlecanprovideusefulreferencesforregulatoryagencies,listedcompanies,andauditinstitutions,helpingthembetterunderstandandrespondtotheimpactofauditorchangesonauditqualityinpractice,therebyimprovingauditquality,protectinginvestorinterests,andpromotingthehealthydevelopmentofthecapitalmarket.二、文獻(xiàn)綜述Literaturereview審計(jì)師變更與審計(jì)質(zhì)量之間的關(guān)系一直是審計(jì)領(lǐng)域的重要議題。眾多學(xué)者對(duì)此進(jìn)行了深入研究，提出了不同的觀點(diǎn)和理論。本文將從審計(jì)師變更的動(dòng)因、審計(jì)質(zhì)量的影響因素以及簽字注冊(cè)會(huì)計(jì)師未變更的經(jīng)驗(yàn)證據(jù)三個(gè)方面對(duì)相關(guān)文獻(xiàn)進(jìn)行綜述。Therelationshipbetweenauditorchangesandauditqualityhasalwaysbeenanimportantissueinthefieldofauditing.Numerousscholarshaveconductedin-depthresearchonthisandproposeddifferentperspectivesandtheories.Thisarticlewillreviewrelevantliteraturefromthreeaspects:themotivesforauditorchanges,factorsaffectingauditquality,andempiricalevidenceofsignedcertifiedpublicaccountantsnotchanging.關(guān)于審計(jì)師變更的動(dòng)因，學(xué)者們普遍認(rèn)為主要包括客戶需求、審計(jì)師自身因素以及市場(chǎng)環(huán)境等?？蛻粜枨罂赡苁怯捎诳蛻魧?duì)審計(jì)師的服務(wù)不滿意，或者尋求更具競(jìng)爭(zhēng)力的報(bào)價(jià)。審計(jì)師自身因素可能包括審計(jì)師的專業(yè)能力、獨(dú)立性以及聲譽(yù)等。市場(chǎng)環(huán)境的變化，如監(jiān)管政策的調(diào)整、審計(jì)市場(chǎng)的競(jìng)爭(zhēng)格局等，也可能影響審計(jì)師變更的決策。Scholarsgenerallybelievethatthereasonsforauditorchangesmainlyincludecustomerneeds,auditorfactors,andmarketenvironment.Thecustomer'sdemandmaybeduetodissatisfactionwiththeauditor'sserviceorseekingmorecompetitivequotes.Theauditor'sownfactorsmayincludetheauditor'sprofessionalability,independence,andreputation.Changesinthemarketenvironment,suchasadjustmentsinregulatorypoliciesandthecompetitivelandscapeoftheauditmarket,mayalsoaffectthedecisiontochangeauditors.審計(jì)質(zhì)量的影響因素的研究廣泛而深入。審計(jì)質(zhì)量是指審計(jì)師發(fā)現(xiàn)并報(bào)告客戶財(cái)務(wù)報(bào)表中錯(cuò)誤和舞弊的聯(lián)合概率。影響審計(jì)質(zhì)量的因素眾多，包括審計(jì)師的專業(yè)能力、審計(jì)程序的執(zhí)行、客戶特征以及審計(jì)師與客戶的關(guān)系等。其中，簽字注冊(cè)會(huì)計(jì)師的專業(yè)能力和獨(dú)立性對(duì)審計(jì)質(zhì)量具有重要影響。Theresearchontheinfluencingfactorsofauditqualityisextensiveandin-depth.Auditqualityreferstothejointprobabilityofauditorsdiscoveringandreportingerrorsandfraudinclientfinancialstatements.Therearemanyfactorsthataffectauditquality,includingtheprofessionalcompetenceofauditors,theexecutionofauditprocedures,customercharacteristics,andtherelationshipbetweenauditorsandcustomers.Amongthem,theprofessionalabilityandindependenceofthesigningcertifiedpublicaccountanthaveasignificantimpactonauditquality.關(guān)于簽字注冊(cè)會(huì)計(jì)師未變更的經(jīng)驗(yàn)證據(jù)，學(xué)者們通過(guò)實(shí
