【摘要】 双重上市(Dual listing)是指一家公司的股票在一个以上的证券交易所挂牌上市的行为。相对于西方企业,中国企业的双重上市活动起步较晚,但是近年来,中国企业的双重上市活动日益增多,不仅越来越多的境外上市中国企业返回境内证券市场双重上市,而且境内证券市场上市的中国企业也开始选择到境外证券市场双重上市。双重上市对于投资者、上市公司、证券市场的影响日益增强。本文按照首次上市发行地点将企业的双重上市行为分成“先外后内”、“先内后外”以及“同时上市”三种模式,分别分析了采取“先外后内”双重上市模式和采取“先内后外”双重上市模式的两类企业双重上市前后公司治理和公司绩效的变化,在此基础上探讨了双重上市对企业公司治理和公司绩效的影响。基于研究结果,本文对投资者、上市公司管理层和政府管理部门提出了相应建议。首先,本文回顾和梳理了国内外学者的有关企业双重上市的研究,并对双重上市所涉及的公司治理理论、法律渊源理论和约束假说等理论进行阐释,在此基础上提出了一个双重上市对公司治理与企业绩效影响的分析框架。其次,本文分析了中国境内企业双重上市的历程和政策背景,并对在香港地区上市的境内双重上市公司的特征进行分析。第三,本文比较分析了中国内地和香港地区两地上市公司的法律制度环境的差异,包括两地法律渊源的差异、公司法和证券法的差异以及有关公司治理准则的差异,并对两地的执法质量进行了比较。第四,本文以境内首家采取“先内后外”模式双重上市的公司——中兴通讯公司为例,分析中兴通讯公司到香港地区双重上市后公司治理、公司绩效的变化,讨论双重上市对公司治理与公司绩效的影响。第五,本文从纵向和横向两个维度对采取“先外后内”模式双重上市企业的公司治理与企业绩效进行比较研究。在纵向维度,本文选择了10家双重上市公司为样本实证检验其双重上市前后公司治理、企业绩效的变化。在横向维度,本文选择29家双重上市公司以及29家仅在境内证券市场上市的同类匹配公司为样本实证检验两类公司的公司治理差异、公司绩效差异以及双重上市对于调节公司治理与公司绩效关系的影响。最后,对本文的案例研究和实证研究的结论进行总结,根据研究结果对投资者、上市公司管理层和政府管理部门提出了相应建议。同时,指出本文的研究局限以及未来进一步的研究方向。更多还原
