摘要美国安然公司和世界通信的丑闻，使得内部控制相关问题的研究也成为各界讨论的焦点, 这些事件的发生显示出公司内部制度的缺陷。受其影响，我国政府也逐步建立和完善企业内部控制体系,从2006年起我国便先后发布了多项内部控制信息披露的指引，引导企业进行规范化的内控信息披露。本文将以创业板市场为研究对象，选取披露了2014年度内部控制评价报告的公司,剔除披露日前后五日发布季报的和连续三天无股票交易的公司，最终产生195个公司为样本。构建包含内控披露信息及时性、完整性和有效性在内的内部信息披露指标体系，用事件研究法,通过建立超额收益率模型实证分析内控信息披露质量对股价波动的影响。所得结论表明当企业向外界披露质量较高的内部控制信息时能够给股价带来正向的波动，这说明企业在一定程度上能够通过改善公司内部控制来获取资本市场的支持。42790
