民营控股的混合所有制与非混合所有制企业的RD研究摘要所有制改革是改革开放以来经济体制改革的重点与难点,从限制私有制经济到承认非公有制经济,再到发展混合所有制经济,混合所有制经济已被确认为社会主义市场经济的主要实现形式。然而,在经济社会发展的新时期,混合所有制经济发展还有许多关键问题尚待解决。并不是所有类型和所有行业的国有企业都适合发展成为混合所有制企业,以金融、电信为代表的竞争性领域应当完全放开发展混合所有制经济,以石油、稀土为代表的稀缺资源领域应该进行必要的限制,以铁路和电力为代表的规模经济行业应区分产业链上不同环节,有选择地发展混合所有制经济,而公益性领域则不适合发展混合所有制经济。本文总结并评价了我国混合所有制的认识发展过程,分析了发展混合所有制经济的范围、治理结构、行业选择和规制设计,以期为国企发展混合所有制的健康有序提供理论依据与经验支持。关键词：混合所有制；非混合所有制；对比研究AbstractOwnershipreformistheemphasisanddifficultyofthereformoftheeconomicsystemsincethereformandopeningup,fromtherestrictionofprivateownershipeconomytoadmitthenon-publicsectorsoftheeconomy,andtodevelopthemixedownership,themixedownershipeconomyhasbeenrecognizedasamajorformofrealizationofsocialistmarketeconomy.However,inthenewperiodofeconomicandsocialdevelopment,developmentofthemixedownershipeconomytherearemanykeyproblemstobesolved.Notalltypesandallsectorsofthestate-ownedenterprisesaresuitablefordevelopmentintomixedownershipenterprises,competitivefieldtothefinancial,telecommunicationsastherepresentativeshallbefullyliberalizeddevelopingmixedownershipeconomy,scarceresourcestooilfield,rareearthastherepresentativeshouldbethenecessaryrestrictions,industryscaleeconomytorailwayandpowerastherepresentativeofthetodistinguishbetweenthedifferentsectorsoftheindustrychain,selectivelydevelopthemixedownershipeconomy,andthepublicdomainisnotsuitableforthedevelopmentofthemixedownershipeconomy.Thispapersummarizedandourunderstandingofthedevelopmentofthemixedownershipofprocessevaluation,analyzesthedevelopmentofmixedallrange,economicgovernancestructure,industryselectionandregulationdesign,inordertoprovidetheoreticalbasisandexperiencetosupportorderlymixedownershipforthehealthdevelopmentofstate-ownedenterprises.Keywords:mixedownership;nonmixedownership;comparativestudy1.绪论..............................................................21.1研究背景....................................................21.2研究目的及意义..............................................21.3基本概念的界定..........................................31.3.1民营控股混合所有制与非混合所有制的区别................31.3.2企业业绩..............................................42基本理论概述......................................................42.1RD的定义.....................................................42.1.1RD的构成及主要特征.....................................52.1.2RD投入主要影响因素....................................53.1研究假设（股权结构影响RD的投入）...........................63.2模型设计（投入与产出模型）..................................63.2.1样本选取..............................................63.2.2变量定义..............................................73.2.3数学模型..............................................74.RD投入与民营控股企业业绩相关性实证分析..........................74.1描述性统计分析..............................................84.2变量的相关性分析............................................84.2.1RD投入力度与股权结构的相关性分析...........
