会计信息可比性、信用评级与股价信息含量

Comparability of Accounting Information,Credit Rating and Stock Price Information Content

通过引入信用评级这一中介变量,进一步明晰了会计信息可比性作用于股价信息含量的传导路径和情景机制。选取2010~2020年沪、深两市A股上市公司为样本进行实证检验,研究表明:会计信息可比性可以提高上市公司股价中的信息含量;信用评级在会计信息可比性与股价信息含量之间发挥了部分中介作用。

By introducing credit rating as an intermediary variable,this study further clarifies the transmission path and situational mechanism of accounting information comparability′s action on stock price information content.This study selects the A-share listed companies in Shanghai and Shenzhen from 2010 to 2020 as samples for testing.The research shows that the comparability of accounting information can enhance the information content in the stock price of the listed companies and credit rating partially plays an intermediary role between accounting information comparability and stock price information content.
