注册会计师的任期和强制轮换与会计盈余稳健性——来自沪深A股上市公司的经验证据

The Influence on Accounting Conservatism of Client betweem CPA's Tenure and Rotation——Evidence from Chinese stock market

本文实证检验了注册会计师定期轮换规定对我国上市公司会计报告盈余稳健性的影响。研究发现:签字注册会计师任期对客户公司的会计报告盈余稳健性的影响受到会计师事务所与客户公司经济依存度的作用,在事务所经济重要程度较低的客户公司中,签字会计师任期的延长显著降低会计报告的盈余稳健性;而在事务所经济重要程度较高的客户公司中,任期与会计盈余稳健性的关系则并不明确。同时,上市公司在按照《关于证券期货审计业务签字注册会计师定期轮换的规定》更替签字注册会计师后,会计稳健性并未发生显著变化。这表明尽管注册会计师定期轮换规定的实施在我国是必要的,但其实施规定对上市公司盈余稳健性的提高并不完善。本文建议未来轮换规定可以考虑在事务所轮换层面提供更细致的要求,削弱现有轮换规定下客户公司与事务所长期合作关系。
