Internal Control Quality,Economic Policy Uncertainty and ESG Rating Divergence
With the continuous promotion of the"dual carbon"strategy,ESG concepts are gradually integrated into the company's operation and management,and it is of great practical significance to understand the mechanism behind the divergence of corporate ESG ratings and better utilize ESG information.This paper takes A-share listed companies in Shanghai and Shenzhen from 2015 to 2022 as research samples to empirically test the impact of internal control on ESG rating divergence and its mechanism.The research shows that internal control can restrain ESG rating divergence.The uncertainty of economic policy can enhance the inhibiting effect of internal control on ESG rating divergence.Internal control can improve the quality of information disclosure and reduce information asymmetry through supervision and management behavior,thus reducing ESG rating divergence.In non-Big Four audit enterprises and non-state-owned enterprises,the internal control has a more distinctive inhibiting effect on ESG rating divergence.Therefore,the government should strengthen supervision and evaluation and external audit supervision,and enterprises should also use information technology and automation tools to improve the quality of internal controls,so as to reduce the ESG rating divergence and promote the high-quality development of enterprises.
