IPO上市公司承销费用的影响因素摘要论文从国内外研究现状出发，对前人的研究成果进行了简单的介绍，这些也是论文研究的理论基础。论文第二章重点介绍了当期收益理论和市场份额理论，从当期收益角度来说，承销商压低新股上市价格的程度越大越好，但从市场份额的角度来讲，新股上市前后股价差异过大会直接影响承销商的声誉，进而影响到其市场份额，最终影响到其经营状况。第三章是对IPO上市公司承销费用的分析，介绍了承销费用的组成，主要影响因素，并对一些主要影响因素进行了分析，这同时也是论文后期研究的基础。第四章在第三章的基础上进行了变量设定、研究假设、模型选择，介绍了样本的选择和数据来源。第五章是论文的重点部分，对论文的实证结果进行了描述性分析和独立T检验，第六章是全文的总结，对上述研究成果进行了归纳，并说明论文的不足之处及后期的主要研究方向。关键词：IPO上市公司；承销商；影响因素AbstractThispaperfromthedomesticandforeignresearchpresentsituation,hascarriedonthesimpleintroductionofpreviousstudies,whichisthetheoreticalbasis.Thesecondchapterfocusesonthecurrentincometheoryandmarkettheory,fromthecurrentincomeperspective,theUnderwritersholdingdownthepriceoftheIPOdegreebiggerisbetter,butfromamarketperspective,pricedifferencebeforeandafterthelistingofnewshareswilldirectlyinfluencetheunderwriterreputation,thusaffectitsmarketshare,andultimatelyaffectthetheoperatingstatus.ThethirdchapteristheanalysisoftheIPOlistingCorporationunderwritingfee,introducestheunderwritingfee,themaininfluencingfactors,andtosomemaininfluencefactorsareanalyzed,whichisalsothefoundationoflaterresearch.Inthefourthchapter,thethirdchapteronthebasisofthevariables,researchhypothesis,modelselection,thesampleselectionanddatasources.Thefifthchapteristhekeypartofthethesis,theempiricalresultofpapermakesdescriptiveanalysisandindependentTtest,thesixthchapteristhesummaryofthispaper,theresearchachievementsaresummarized,andthemainresearchdirectionofdeficienciesandlaterinthe.Keywords:IPOlistingCorporation;underwriter;influencingfactors目录摘要...............................................................11引言..............................................................31.1研究背景....................................................31.2主要研究方法................................................31.3国内外研究现状..............................................31.3.1国外研究现状...........................................31.3.2国内研究现状..........................................41.3．3文献评述..............................................52相关理论基础......................................................72.1“当期收益”理论分析........................................72.2“市场份额”理论分析........................................73IPO上市公司承销费用分析..........................................93.1承销费用及其组成............................................93.2IPO上市公司承销费用影响因素分类简述.........................93.2IPO上市公司承销费用影响因素分析............................114．研究设计.......................................................124.1变量设定...................................................124.2研究假设...................................................124.3模型的设定.................................................124.4样本选择与数据来源.........................................135实证结果分析.....................................................145.1各变量的描述性分析.........................................145.2独立T检验...............
