事务所规模与年报会计政策“类准则”披露——基于文本分析的经验证据

Research on the Audit Firm Size and the“Standard-like”Accounting Policy Disclosure in Annual Reports:Empirical Evidence Based on Text Analysis

通过计算上市公司年报会计政策披露的“类准则”程度,讨论会计师事务所规模是否为影响上市公司会计政策披露行为的重要因素。研究发现:(1)由规模较大的会计师事务所审计的上市公司,年报会计政策披露的“类准则”程度较低,会提供更多公司会计政策的个性化信息。(2)在上市公司风险增强和会计准则重大变化的两大类场景中,事务所规模与年报会计政策披露“类准则”程度之间的关系都得到增强,说明事务所的风险压力和事务所能力是重要的机制路径。(3)由同一事务所审计的上市公司会计政策披露的“类准则”程度更一致,具有同所效应。(4)基于会计师事务所变更的检验发现,若变更后的事务所规模更大,则会计政策披露的“类准则”程度会降低;若变更后的事务所规模更小,则会计政策披露的“类准则”程度会提高。

This paper discusses whether the audit firm size will be one of the important factors affecting the accounting policy disclosure behavior of listed firms by calculating the degree of“standard-like”of accounting policy disclosed in annual reports.The findings are as follows:(1)The accounting policy disclosed in the reports of companies audited by large-size audit firms are less“standard-like”,which will provide more personalized information about the accounting policy of the companies.(2)The relationship between the audit firm size and the degree of“standard-like”of accounting policy in annual reports will be strengthened when the risk of the firm rises or when the accounting standards change significantly,indicating that the risk pressure and the ability of audit firm are important influence paths.(3)Further research finds that the degree of“standard-like”of accounting policy in annual reports of companies audited by the same audit firm is more consistent with each other.(4)In the robustness test,the result is also consistent with the main hypothesis when the audit firm changes,which means that the degree of“standard-like”of accounting policy will be reduced if the size of the changed audit firm is larger,and will increase if the size of the changed audit firm is smaller.
