会计师事务所异质性对财务重述的影响研究——基于媒介环境的调节效应分析

Based on the theory of agency cost, contract, information asymmetry, agenda setting and other classical theories, this program reveals the staus quo of financial restatement among Chinese listed firms, identifying the intention and influencing mechanism of financial restatement by listed firms. Following these, this program studies the effect of audit firm heterogenicity on financial restatement, considering the moderation effect of media environment. This program is based on accounting misstatement period and error correction period, and studies the influencing mechanism of audit firm heterogenicity on financial restatement by visiting and interviewing audit firm. Then the program empirically tests the effect of audit firm heterogenicity on financial restatement with descriptive statistics, logit regression and other econometric ways based on Chinese capital market, and examines whether this effect depends on media environment. Besides, this program focuses on whether factors influencing financial restatement are different between first restatement and repeat restatement, and tests the intentions of listed firms firing auditor following restatement announcement with Multinomial logit model, and analyzes the attitute of successor auditor to repeat restatement. This program helps to enrich and complete the theory of accounting information quality, providing evidence for clarifying the relationship between external audit, media environment and financial restatement.

本项目以代理成本理论、契约理论、信息不对称理论、议程设置理论等经典理论为基础，揭示我国上市公司财务重述的现状，识别上市公司发生财务重述的动机、影响机理，在此基础上研究会计师事务所异质性对其影响作用，并结合媒介环境的调节效应进行分析。本项目以会计差错发生期以及会计差错更正期为视角，通过对事务所的走访和访谈分析会计师事务所异质性对财务重述的影响机理；然后以我国全部上市公司为样本，通过描述性统计、logit模型等统计和计量方法测试会计师事务所异质性对财务重述的影响，并分析这种影响在不同媒介环境下的差异性。此外，本项目重点关注一次重述与二次重述时财务重述影响因素的异同情况，通过Multinomial logit模型检验上市公司在发生财务重述后解聘会计师事务所的动机，并分析继任事务所对二次重述的态度。本项目有助于会计信息质量理论的丰富与完善，为厘清外部审计、媒介环境与财务重述间的关系提供证据。

上市公司的财务重述行为不利于会计信息质量的提升，有碍资本市场的健康发展。以往的文献将财务重述与会计差错完全混淆在一起，未能考虑到会计差错发生与会计差错更正的分期。本项目以会计差错发生期以及会计差错更正期为视角，通过对事务所的走访和访谈分析会计师事务所异质性对财务重述的影响机理；然后以我国全部上市公司为样本，通过描述性统计、logit模型等统计和计量方法测试会计师事务所异质性对财务重述的影响，并分析这种影响在不同媒介环境下的差异性。此外，本项目重点关注一次重述与二次重述时财务重述影响因素的异同情况，通过Multinomial logit模型检验上市公司在发生财务重述后解聘会计师事务所的动机，并分析继任事务所对二次重述的态度。此外，本项目扩展了研究视角，对上市公司财务重述、高管薪酬、年报披露及时性等方面内容进行了研究。本项目的研究有助于改变会计差错发生期与更正期相分离的研究局面，本项目有助于会计信息质量理论的丰富与完善，为厘清外部审计、媒介环境与财务重述间的关系提供证据。
