摘要
选取深交所的信息披露考核结果作为衡量上市公司信息披露质量的指标,对有证券分析师预测2013年度盈利状况的深市A股上市公司进行实证研究。结果表明,上市公司信息披露政策越透明,证券分析师的跟进数量越多,预测的分歧度越小,准确度越高。说明证券分析师的预测依据主要来自上市公司的会计信息,会计信息披露不全面或者虚假披露,会直接影响证券分析师的盈利预测,进而影响投资者对上市公司未来发展前景的评价。
The evaluation results of information disclosure of Shenzhen Stock Exchange were taken as measure index of information disclosure quality of listed companies. Earning performance in year 2013 of these list companies was empirically investigated. Results show that the more transparent of the listed companies＇ information disclosure policy,the more the number of securities analysts to predict; the smaller the difference of degree,the higher the accuracy. This shows that securities analysts＇ forecasts are mainly based on the accounting information of public companies. If accounting information disclosure is not comprehensive or false announced,it will directly affect the securities analysts＇ forecasts,and will also affect investors＇ evaluation of the company＇s future development prospect.
