盈余信息质量对企业创新的影响研究——基于债务异质性的中介效应检验

The Impact of Earnings Information Quality on Enterprise Innovation:A Test of Mediating Effect based on Debt Heterogeneity

信息是企业与资本市场沟通的重要渠道,影响企业的财务行为与决策。本文以2011-2018年我国A股上市公司为样本,实证检验了盈余信息质量对企业创新水平的影响以及债务异质性在其中所发挥的作用。结果发现:无论用应计盈余管理程度还是盈余透明度衡量,较高的盈余信息质量都能够促进企业创新,并且债务异质性在其中发挥部分中介效应作用。高质量的盈余信息通过提升债务来源的多元化、期限结构的丰富程度,缓解融资约束,促进企业创新。企业债务异质性同时也发挥了积极的治理效应,促进企业投资更为有效,提升创新水平。进一步研究发现:不同股权性质下,盈余信息质量对企业创新都存在显著正相关关系,但相比于国有企业,盈余信息质量对非国有企业创新的促进作用程度更大。本研究对提升企业盈余信息质量、提高创新水平,实施国家创新驱动发展战略具有一定启示意义。
