基于我国沪深两市上市公司2002年至2005年的数据,对我国上市公司从董事会结构和董事会成员工作情况角度,对董事会在上市公司盈余质量上的控制作用进行了实证分析.实证发现:董事会规模较大、董事会中设立审计委员会对公司盈余质量的正面作用越大,且相对于基本盈余回报模型,有增量信息解释能力.董事会规模在13人时,董事会对盈余质量的正面效应最大.董事会成员工作情况(董事会开会的次数、独立董事的工作地点与公司所在地一致性、成立一年以上的审计委员会)对盈余质量的提高有一定的成效,且相对于基本盈余回报模型,有一定的增量信息解释能力.但实证不支持独立董事对盈余质量提高的正面作用.
Based on the data from 2002 to 2005 of the listed companies in Shanghai and Shenzhen, this paper makes an empirical analysis of the controlling role of the board of directors in the earnings quality of listed companies from the perspective of the structure of the board of directors and the work of the members of the board of directors.It is found that the board of directors The larger the positive effect of setting up an audit committee in the board of directors on the company’s earnings quality and the ability to explain the incremental information relative to the basic earnings model, the positive effect of the board on earnings quality is greatest when the size of the board of directors is 13. The work of the board of directors (the number of meetings of the board of directors, the consistency of the place of work of the independent directors with the company, and the audit committee established for more than one year) have some effect on the improvement of the earnings quality. Compared with the basic model of the return on earnings, Incremental ability to explain information, but the empirical evidence does not support the positive role of independent directors in improving the quality of earnings.
