制度环境、管理者过度自信对成本粘性影响研究

Studies on the Impact of Institutional Environment and Managerial Over Confidence on Cost Stickiness

选取2018年至2021年沪深A股上市公司作为样本,研究管理者过度自信与成本粘性的关系,并进一步考察在不同市场化进程和法治水平的情况下,这种关系是否存在差异。实证结果表明:管理者过度自信可能会导致错误的成本决策,加剧公司成本粘性;而外部制度环境的改善能够在一定程度上缓解管理者过度自信造成的成本“粘性”加剧问题。这对于完善我国的职业经理人市场、强化对企业管理者的全面素质管理、改善绩效评估和薪酬管理体系、加强法律制度建设与人才培养具有深远的意义。

The paper selects A-share listed companies in Shanghai and Shenzhen from 2018 to 2021as a sample to study the relationship between manager overconfidence and cost stickiness,and further investigate whether there are differences in this relationship under different marketization processes and legal levels.The empirical results show that managers’overconfidence may lead to wrong cost decisions and aggravate the cost stickiness of the company.The improvement of external institutional environment can alleviate the aggravation of cost“stickiness”caused by managers’overconfidence to a certain extent.This is of far-reaching significance to promote enterprises to improve the supervision and incentive of managers,promote relevant national departments to improve the resource allocation of product market,and strengthen the construction of legal system and talent training.
