摘　　要：超过120个国家要求上市公司采用国际会计准则(IFRS),然而对强制采用IFRS所带来的信息环境改善的实证研究结果往往是相互矛盾的,并且没有分离出强制采用IFRS所带来的信息可比性和信息质量效应的影响作用。本文通过研究强制采用IFRS对信息环境的影响,发现分析师对强制采用IFRS的公司的预测准确性高于其它类型的公司。通过控制相关的影响因素,对具体公司层面的预测数据进行分析,本文发现信息环境的改善与信息可比性和信息质量的提高相关。本研究表明强制采用IFRS提高了信息的可比性和信息质量,从而改善了资本市场中的会计信息的媒介作用和其信息环境。More than 120 countries require that publicly listed companies adopt the International Financial Reporting Standards（IFRS）. However, the empirical evidence about IFRS＇ presumed benefits are often conflicting and fail to distinguish between information quality and comparability. In this paper, the study examines the effect of mandatory IFRS adoption on firms＇ information environment. This study finds that after mandatory IFRS policy is adopted, more consensus forecast errors are decreased for firms that mandatorily adopt IFRS than for forecast errors of firms that do not mandatorily adopt IFRS. This study also holds constant for any information effect of IFRS adoption and finds that the increase in forecast accuracy is partly driven by comparability benefits. This study establishes this result by analyzing three groups of analysts. First, this paper studies the group of analysts who help companies report under a single local GAAP before mandatory adoption. After mandatory adoption is implemented, some firms switch to IFRS while other firms continue to report under local GAAP. For these analysts, the study expects the accounting comparability to decrease. Second, this paper studies another group of analysts who helped firms report under a single local GAAP before mandatory adoption and after mandatory adoption. All firms responsible by the group of analysts switched to IFRS. For these analysts, the study expects the accounting comparability to remain the same. Third, this study examines another group of analysts who helped firms report under multiple local GAAPs before mandatory adoption, but after mandatory adoption all firms switch to IFRS. For these analysts, the study expects accounting comparability to increase. If information effects exist for mandatory adopters, all three groups of analysts are going to be benefited. To eliminate the possibility that an analyst＇s choice to change firm coverage could affect the results, this study includes only mandatory adopters. Consistent with the presence of a c
