制度环境、股改进程与会计盈余的信息含量研究

A Study on Institutional Environment, Process of the Share-splitting Structure Reform and Information Content of Accounting Earnings

本文从股改进程的角度出发,结合上市公司所处的制度环境,研究了股改进程中会计盈余的信息含量问题。研究发现,地区制度环境越好,率先完成股改的上市公司其会计盈余的信息含量越低。对于这一研究结果,进一步运用行为金融学的"噪音交易理论"进行了解释。本文的研究对于认识股权分置改革的经济后果以及理解我国证券投资者的市场交易行为具有一定的意义。
