摘要
笔者以2007年至2016年A股上市公司为样本,检验管理层过度自信对会计信息可比性的影响。研究发现,过度自信的管理者具有提高会计信息可比性的动机,表现为管理层过度自信与会计信息可比性显著正相关,并且按融资约束程度、是否为高科技企业以及媒体关注度高低分组检验发现,在高融资约束、高科技企业以及媒体关注度高的样本中,管理层过度自信对会计信息可比性的正向影响更强。这表明:为缓解融资约束而改善信息环境以及自我实现心理是过度自信的管理者提高会计信息可比性的内在动机。本文从管理层动机视角为会计信息可比性的影响因素研究提供了经验证据。
Taking the listed A-share firms during 2007 to 2016 as samples. We investigate the impact of managerial overconfidence on accounting information comparability. We find that managerial overconfidence has a positive effect on accounting information comparability. We also find that the positive relationship between managerial overconfidence and accounting information comparability is more significantly in firms with high financial constraint,high-tech firms and firms with high media coverage. The results show that improving the information environment to mitigate financial constraint and satisfy their self-fulfilling demand is the main motivation for top managers to improve accounting information comparability.
