External Communication of Audit Institutions and Governance Efficiency of State-owned Enterprises
As national audit goes across field,section and region,the external communication of audit institutions are increasingly important in their role of serving governance.We use the sample of listed state-owned enterprises at provincial and below levels from 2013 to 2019,and manually collect data of external communication interaction among audit offices and municipal governments,audit offices at different levels,and audit offices in different regions,to explore how external communication of audit institute affects the governance efficiency of SOEs.We find that communication both among audit offices at different levels as well as among audit offices in different regions can improve the economic value added(EVA)ratio of SOEs by increasing audit depth.The effect of communication between audit offices and municipal governments is not significant.The effect of communication among audit offices at different levels as well as among offices in different regions is stronger in regions where audit independence and government transparency are lower,but appears differently on audit coverage and audit result conversion.This study expands the research on governance efficiency of SOEs,and provides empirical evidence for national audit's micro-governance effect and its mechanism.
