Auditors’ response to earnings management after split-share structure reform in China

Purpose This study aims to investigate whether and how auditors responded to the documented increases in earnings management after split-share structure reform (SSSR) in China, as manifested in auditors’ propensity to issue modified audit opinions (MAOs) after the SSSR. This study further investigates how client importance and auditor size influence auditors’ response to earnings management after the SSSR. Design/methodology/approach This study adopts logit regression models to investigate auditors’ propensity to issue MAOs to their clients that appear to manage earnings after the SSSR. Initially, including all Chinese publicly listed firms from the CSMAR database, the sample for final analyses consists of 21,904 firm-year observations for 1,290 unique listed firms during the period 2001–2020. The sample period surrounds the implementation of the SSSR, which started in 2005, allowing the examination of auditors’ propensity to issue MAOs after vis-à-vis before the SSSR. Findings The authors find that non-Big10 auditors in China were less likely to issue MAOs to their economically important clients who appear to manage earnings after SSSR. However, in the years of non-tradeable shares being released to the markets, both Big10 and non-Big10 auditors were less likely to issue MAOs to their economically important clients who appear to manage earnings. The findings suggest that auditors may have compromised auditor independence in response to earnings management after the SSSR, likely due to the pressure from their economically important clients. Originality/value This paper contributes to the literature, specifically the practice and theory in auditing, by shedding light on ever-changing auditors’ reporting behaviour, especially with regard to auditor independence. It also adds to the growing body of literature on the impact of institutional changes on auditing practices worldwide. The findings of this study further suggest that the recently documented declining demand for high-quality audits after the SSSR may be motivated by the clients’ intention to manage earnings after the SSSR.
