智力资本价值创造效率与股权资本成本——基于注册会计师会计报表审计鉴证意见中介效应的研究

摘要

本文以注册会计师会计报表审计鉴证意见为中介变量,利用2008-2015年我国上市公司A股有关数据,检验智力资本价值创造效率对股权资本成本的影响.研究发现:注册会计师在出具审计意见时受到企业智力资本价值创造效率的影响;企业智力资本价值创造效率的提高可以改善注册会计师会计报表审计鉴证意见,降低其股权资本成本;注册会计师会计报表审计鉴证意见是人力资本价值创造效率影响股权资本成本的有效传导路径之一,但不是结构资本价值创造效率降低股权资本成本的有效中介变量.企业应重视智力资本并基于不同类型智力资本的特征对其进行有效管理,以降低其股权资本成本.%Taking the CPA audit opinion report as an intermediary variable,this paper explores how Intellectual Capital Added Efficiency affects the cost of equity capital based on the data of China′s listed companies from 2008 to 2015.
