摘要
本文基于2009—2014年我国上市公司业绩预告和分析师盈利预测数据,从管理层信息披露和分析师预测的角度研究融资融券交易的信息治理效应。通过比较分析融资融券标的股票与非标的股票,以及股票加入融资融券标的前后上市公司信息环境的差异,我们发现融资融券交易同时具有内部信息治理和外部信息治理的作用。其中内部信息治理效应表现为,融资融券交易的推出有效促使了管理层对非强制信息和坏消息的披露,提高了管理层业绩预告的及时性和准确性;融资融券的外部信息治理效应体现在显著降低了财务分析师对目标公司盈利预测的偏差与分歧。在控制相关因素以及通过双重差分模型控制内生性后,以上结果依然稳健。本文的研究结果表明,融资融券交易通过影响管理层和分析师的信息行为进而影响公司的信息环境,这为融资融券交易改善股票市场定价效率和市场质量提供了新的解释。
