| 中文摘要: | IPO定价,反映了我国资本市场的市场化程度,特别是像在创业板这样一个具有特殊性的市场上,定价效率的高低关系到整个金融环境的有序运行。我国创业板市场的IPO抑价现象,是市场机制不完善的体现,新股发行的首日收盘价与发行价之间存在着较高的差异,本身就是一二级市场间不匹配的一种表现,会对资本市场的有序运行产生不利的影响。 风险资本,是指通过股权投资的形式介入目标公司,以各种形式为公司提供增值服务,并选择合适的时机、适当的方法退出目标公司,实现投资收益。风险资本是一种高风险、高收益的投资模式。 创业板作为风险资本最重要的退出方式之一,为我国风险资本提供了更受欢迎的退出机制,有利于促进后者的发展;而风险资本入股那些在创业板上市的公司,是对公司价值的肯定,有利于降低新股发行的抑价现象,提高定价效率。 本文在经典抑价理论和“认证功能假说”的基础上,选取了我国创业板市场上的相关数据,以风险资本为解释变量,并设置相应的控制变量,来衡量其对首日回报率所代表的IPO抑价程度是否会发挥显著性影响。经实证研究发现,风险资本对我国创业板市场上IPO抑价的现象并没有显著影响。稳健性检验的结果也支持了这一结论。 为了更进一步分析风险资本的存在对创业板IPO抑价影响的深度,本文通过将研究样本区分为有风险资本背景和无风险资本背景的一组,风险资本占前十大股东数量超过两家和不超过两家的一组,以及风险资本合并比例大于均值持股比例和小于均值持股比例的一组,通过各组之间的对比分析和对子样本进行相应的多元线性回归分析,来具体探讨风险资本在降低创业板IPO抑价中所发挥的作用。实证研究的结论表明,中国风险资本在创业板市场上发挥的作用还较弱,无法证明风险资本的存在和首日回报率所代表的IPO抑价程度存在显著的相关关系。 | |
| 英文摘要: | IPO pricing reflects the degree of marketization of China's capital market, particularly on such a special market of the gem.The level of pricing efficiency relates to the orderly running of the financial environment. GEM IPO underpricing phenomenon is a manifestation of market mechanisms are not perfect. Venture capital is a form of intervention the target company through equity investments, providing value-added services to companies in various forms, and select the appropriate time and appropriate way to exit the target company to achieve return on investment. The gem as one of the most important ways of venture capital is conducive to promoting the development of the latter, and venture capital investing in those companies listed on the gem, would reduce the IPO underpricing phenomenon and improve price efficiency. This article based on classical theory of underpricing and "certification function hypothesis" choose venture capital as explanatory variables, and set the key variables, measure its impact on the first-day return. Empirical studies have found that venture capital had no noticeable effect on the gem IPO underpricing. To more further analysis the effect of venture capital on IPO underpricing phenomenon, this article divide samples for groups of venture capital background and no venture capital background,to specific discussion the role venture capital played in reduced IPO underpricing phenomenon. | |
