管理者团队中垂直对特征影响会计稳健性的实证研究

Empirical Study of Vertical Dyad Linkage Characteristics in Management Group on Accounting Conservatism

本文以深沪两市A股2007-2010年的数据为研究样本,实证检验了管理者团队中垂直对特征对会计稳健性的影响。研究发现,当团队性别与董事长保持一致且董事长为男性时,性别垂直对特征对会计稳健性的影响显著为负;当团队整体性别与董事长不一致且董事长为女性时,性别垂直对特征对会计稳健性的影响显著为正。年龄垂直对特征对会计稳健性没有影响。管理者团队—董事长学历和任期垂直对特征越大,会计稳健性水平越低,而董事长个人学历越高、任期越长,会在一定程度上削弱这两类垂直对特征影响会计稳健性的程度。管理者团队—董事长学历垂直对特征和任期垂直对特征对会计稳健性的影响,在国有上市公司和非国有上市公司中存在显著差异。这些研究结论对于优化高管团队的结构、提高会计信息的质量水平以及拓展研究的会计稳健性视野和丰富高阶梯队理论研究的内容都有着一定的启示意义。

Based on the data of Shenzhen and Shanghai A-share listed companies from 2007 to 2010, high-level theory as a starting point, from the angle of vertical dyad linkage characteristics of management group, this paper empirically tests vertical dyad linkage characteristics of management group of gender, age, degree, and tenure on accounting conservatism respectively. The research results show that, from the aspects of the total research sample, when the team gender is consistent with the president and the president is male, the effect of gender vertical dyad linkage characteristics on accounting conservatism is significantly negative; When the team gender is inconsistent with the president and the president is female, the effect of gender vertical dyad linkage characteristics on accounting conservatism is significantly positive. The age vertical dyad linkage characteristics of management team to the president have no effect on accounting conservatism. The higher the degree vertical dyad linkage characteristics of management team to the president, the lower the level of accounting conservatism, while higher president education degree will weaken vertical dyad linkage characteristics of degree on accounting conservatism. The higher the tenure vertical dyad linkage characteristics of management team to the president, the lower the level of accounting conservatism, while longer president tenure will weaken vertical dyad linkage characteristics of tenure on accounting conservatism. From the regression result of the comparison between the state-owned listed companies and non- state-owned listed companies, we find that the vertical dyad linkage characteristics of management team to the president degree and tenure are significantly negative in the state-owned listed compa- nies, while the two characteristics are not significant to accounting conservatism in non-state-owned listed companies. The conclusion of this study is helpful to optimize management team structure, improve accounting information quality, expand the vision of accounting conservatism and enrich the upper echelons theory content.
