中文摘要：

文章利用2007-2010年深交所上市公司的数据检验实际控制人对公司信息披露质量的影响。研究发现：当实际控制人为民营单位时，公司信息披露质量较差；实际控制人的股权比例与信息披露质量正相关；实际控制人的控制彬所有权分离度与公司信息披露质量没有明显的相关性。研究结论表明，对公司信息披露质量的研究及规范，不能仅仅停留在直接控股股东层面，而应追溯至实际控制人。

英文摘要：

This paper examines the relationship between the actual controlling shareholder and quality of information disclosure by use of panel data of listed companies from 2007 to 2010 in Shenzhen Stock Exchange. The result shows that a corporation＇ s quality of information disclosure becomes worse when its actual controlling shareholder is a private unit. And the equity ratio of the actual controlling shareholder is positively related to the quality of information disclosure. However, the divergence of controlling rights from cash flow rights is not statistically related to the quality of information disclosure.
