【摘要】 信息环境是影响公允价值相关性的一个重要因素。以相对信息效率测量上市公司的信息环境,采用Ohl-son模型对公允价值信息价值相关性进行研究,结果表明:当相对信息效率较高时,公允价值对股票价格没有增量影响;当相对信息效率较低时,公允价值对股票价格具有增量的影响作用;而当相对信息效率低于一定程度时,公允价值就不再对股票价格具有增量影响。更多还原

【Abstract】 Information environment is an important factor for fair value relevance.By using relative information efficiency to measure the information environment of listed companies and the Ohlson model,this paper studies fair value and the stock price relevance.The result shows that the fair value have no incremental impact on the stock price when the relative information efficiency is high,the fair value have incremental impact on the stock price when relative information efficiency is low,but the fair value will no longer have incremental impact on the stock price when the relative information efficiency falls below a certain level.更多还原
