本科论文摘要永续债券,是非金融企业(发行人)在银行间债券市场注册发行的“无固定期限、内含发行人赎回权”的债券,在国际资本市场上,永续债是比较成熟的金融产品,由于永续债具有发行期限长、延期支付利息及美化报表的特点,受到发行人的追捧,同时由于高息吸引了众多投资者,但是风险和收益是一把双刃剑,投资者在考虑高收益的过程中应当识别投资风险,作为国家监管部门应当加强投资者权益保护,避免因此引起的系统性风险。本文将对永续债投资的风险、风险成因以及如何规避风险进行研究和分析。关键词:永续债,投资人,投资者权益本科论文AbstractSustainablebondsisthebondswithnofixedtermandcontainingtheissuer'sredemptionrightswhichisthenon-financialbusiness(publisher)registeredIssueintheinter-bankbondmarkets.Intheinternationalcapitalmarkets,Sustainablebondsismuchmoreripefinancialproducts,becausesustainablebondshavethefeatureoflongissueperiod,deferredinterestpaymentsandbeautificationstatements.Anditisfamousinpublishers,meanwhile,itattractsmanyinvestorsbecauseofthehighinterest,buttheriskandtheincomearethedouble-edgessword,sotheinvestorsshouldidentifytheriskwhentheyarecontractedbythehighreturns,Astheregulatoryauthorityofanational,weshouldstrengthentheprotectionofinvestors'rightsandinterests,avoidthesystemicrisksbecauseofit.Thisarticlestudyandanalyzetherisk,andalsothecausesoftherisk,weshouldknowhowtoavoidtheriskofsustainablebondsinvestment.Keywords:Perpetualdebt,Investor,Investorequity本科论文目录前言.................................................................................................................................11.综述.................................................................................................................................21.1研究目的及意义..................................................................................................21.1.1研究目的..................................................................................................21.1.2研究意义..................................................................................................21.3国内外研究现状..................................................................................................31.3.1国内研究现状............................................................................................31.3.2国外研究....................................................................................................31.4研究内容..............................................................................................................31.4.1论文框架..................................................................................................31.4.2研究方法..................................................................................................42永续债基本理论和概念..................................................................................................52.1永续债的定义......................................................................................................52.2永续债的基本特征..............................................................................................52.2.1期限长、发行人具有续期选择权或赎回权..........................................52.2.2高票息和高利率......................................................................................52.2.3利息递延支付及利惠推动机制..............................................................52.2.4无担保及与普通债...
