B股公司审计市场供给与需求研究

A Study on the Supply and Demand in Auditing Market: Evidence from Chinese B Share Companies

审计市场上收费定价的趋势及其影响因素越来越引起人们的注意,国内已有的研究文献主要是对审计市场中的供给与需求单独进行研究,忽视了供给与需求间的内生关系,这很可能对研究结果的准确性产生影响。本文选取影响审计定价的多种因素,采用联立方程的研究方式,对B股审计市场中的供给与需求进行综合研究,以期能对我国审计市场中审计供求关系和审计定价因素有所认识。研究结果表明,我国的审计定价中,往往只重视被审计公司的资产规模、拥有的子公司数量和经营活动所跨行业数量等表象指标,而对审计风险重视不够,这与审计市场成熟的西方国家的通行做法不一致。

Previous research on audit market primarily focused on the supply of audit services using single-equation models. Our study examines not only the supply hut also the demand for B share-company auditors in Chinese stock markets. This approach is used to account for the endogeneity between choice of auditor and audit fees. The results indicate that auditee's size, financial leverage, subsidiary numbers, and the industries covered by the auditee's business have significant effect on the audit fee charges. They also indicate that the variables stand for substantial auditing risks, such as ROA, Opinion, Loss, Stock, Recint and Invint are not significant, which is quite different from the usual practice of the Western developed countries' mature audit markets.
