本文以中国新兴市场为例,研究了可扩展商业报告语言(XBRL)对信息不对称的影响。我们专注于XBRL和信息不对称之间的关联(代理后盈利公告漂移[PEAD])在两个所有权结构:国有企业(SOEs),这是在中国占主导地位,和非国有企业(非国有企业)。我们发现,信息不对称显着减少,反映了PEAD的显着下降,强制采用XBRL后,它减少了更显着的国有企业比非国有企业。在我们控制了可能影响PEAD的市场和会计因素后,我们的业绩仍然强劲。我们的论文不仅支持XBRL在提高新兴市场的市场效率的作用,但也首次文件的影响,政府所有权的实施XBRL。
ABSTRACT In this paper, we test the impact of XBRL (eXtensible Business Reporting Language) on information asymmetry in the emerging market of China. We focus on the association between XBRL and information asymmetry (proxied by Post-Earnings-Announcement Drift [PEAD]) across two ownership structures: state-owned enterprises (SOEs), which are dominant in China, and non-state-owned enterprises (non-SOEs). We find that information asymmetry diminishes significantly, as reflected by a significant decline in PEAD, after the mandatory adoption of XBRL, and it diminishes more significantly in SOEs than non-SOEs. Our results remain robust after we control for market and accounting factors that may influence PEAD. Our paper not only supports XBRL's role in improving the market efficiency of the emerging market, but also first documents the impact of government ownership on the implementation of XBRL.
