CEO变更对会计信息可比性的影响研究

The Effect of CEO Turnover on Accounting Information Comparability

本文主要研究中国上市公司的CEO变更如何影响会计信息可比性。研究发现,CEO变更会导致公司的会计信息可比性降低,表明CEO的变更会引起离任和继任CEO的报告动机和背景特征的变化,进而影响其执行准则的动机和行为。从产权性质的角度,国有企业的CEO变更比非国有企业对可比性的不利影响更加显著。就继任CEO的来源而言,相较于内部继任者,外部继任的CEO对可比性的影响更为明显。本文的结论为从微观层面提高会计信息可比性提供了经验证据。

This research mainly investigates that how CEO turnover effects on accounting information comparability and finds that CEO turnover will results in the decrease of comparability. The conclusion shows that CEO turnover will changes incentives and characteristics between pre-and-post CEOs and thus influences their intention and execution for following the accounting standard. Considering the equity nature,the CEO turnover of SOEs has more influence on comparability than of non-SOEs. Then,comparing with the successors who from inside company,the successors who are recruiting from outside will cause significantly negative impact on comparability. The research provides empirical evidence from microcosmic view to improving accounting information comparability.
