集团共同审计能提升劳动收入份额吗?

Does the Common Signing Auditor within a Business Group Increase Labor Income Share?

作为我国经济发展的重要力量,企业集团的内部要素配置效率一直是理论与实务界的重要议题。基于外部信息治理视角,本文探析了共同审计对集团劳动要素分配的提升效应和作用机制。研究发现,集团上市公司共用会计师事务所能够显著提升劳动收入份额,且在资本—劳动替代弹性更小、多元化程度更高以及共用会计师事务所为“四大”时更为明显。机制检验表明,集团共同审计能够改善公司治理、优化投资效率并促进劳动力升级,且对劳动收入份额的提升效应主要体现在员工而非高管层面。本研究拓展了劳动收入份额的微观影响因素及共同审计师的“外溢效应”,以期为提升集团效率、深化收入分配改革、实现共同富裕提供有益参考。

As an important driver of China’s economic development,business groups’resource allocation efficiency has always been an important research topic in the current theoretical and practical circles.Based on the perspective of external information governance,this paper explores the promotion effect of common auditors on the distribution of labor factors in business groups and analyzes the possible mechanism.We find that the group listed companies sharing the same audit firm can significantly increase labor income share.The above effects are more significant in companies with lower capital-labor substitution elasticity,higher degree of group diversification and the“big four”audit firms as auditors.The mechanism test shows that sharing audit firms within the business group can improve the internal governance of the group,optimize the investment efficiency and promote the upgrading of labor force.The increasing effect of labor income share brought by group audits is mainly reflected in employees rather than executives.The study expands the micro-influencing factors of labor income share and the spillover effect of common auditors.It also provides reference for improving business group’s efficiency,deepening income distribution reform and achieving common prosperity.
