Employees serve as a crucial driver for enhancing the competitiveness of firms,and their treatment and protection have increasingly garnered attention from stakeholders and the capital market.Taking the A-share listed companies in the nine key regulated industries in China's Shanghai and Shenzhen stock exchanges from 2008 to 2020 as research samples,this paper empirically examines the impact of workplace safety on audit pricing for the first time,and explores its mechanism based on the perspective of audit risk.The results show that negative workplace safety incidents in firms can significantly increase audit pricing;After considering endogeneity and robustness tests,the conclusion remains valid.Mechanism tests find that negative workplace safety incidents increase the operating risk,financial risk and legal risk of firms,which affects audit risks and leads to increased audit pricing.Further research shows that the relationship between negative workplace safety incidents and audit pricing is more significant in the case of larger-size accounting firms and regions with higher level of rule of law.This paper enriches the relevant research on audit pricing from the perspective of employee treatment.The paper expands the theoretical basis for audit decision-making,and also provides useful reference for investors and regulators to understand the consequences of workplace safety.
