摘　　要：内部审计与外部审计、董事会及高管层共同构成了公司治理的四大基石,彼此之间的良性互动对公司治理发挥的作用也越来越得到企业家和学者的认可。但是关于内部审计质量的衡量标准以及内部审计发挥治理效应的途径,专家学者并没有得到统一的结论,这些方面仍然有待探索。笔者在研究过程中采用规范研究和实证研究相结合的方式。在规范研究过程中,我们以委托代理理论和内部控制理论为理论基础,分析了内部审计与外部审计、董事会及高管层的互动关系,揭示了内部审计通过发挥咨询与确认服务,从而实现公司治理效应、提高绩效水平的路径。在实证研究方面,从内部审计部门规模以及内部审计执行力度两个方面衡量内部审计质量,并通过回归分析研究它们与公司绩效水平的关系。此外我们引入公司规模作为调节变量,从而更加深入地探讨了内部审计对公司绩效的影响机制。实证结果证明,公司规模对内部审计部门规模、内部审计执行力度与公司绩效之间的关系具有显著的正向调节作用。Internal audit,external audit,board of directors and senior management together form the four cornerstones of corporate governance,the role of positive interaction between them on corporate governance is increasingly recognized by entrepreneurs and scholars. But,experts have not reached unified conclusion on internal audit quality metrics and internal audit governance effects. These areas still need to be explored. This paper is a mixture of normative and empirical research. In the part of the study specification,we analyze internal and external audit,relationship with the board of directors and senior management interaction,and reveal the internal audit and confirmation by an advisory service in order to achieve the effect of corporate governance,to improve the performance level of the path on the basis of agent theory and internal control theory. In the empirical study,this paper measures the quality of internal audit from the internal audit department size and internal audit enforcement,and study their relationship with the company＇s performance level by regression model. In addition,we introduce firm size as the regulated variable,and further in-depth discussion of internal audit on corporate performance impact mechanism. Empirical results show that the relationship between company scale and internal audit department scale,internal audit enforcement and corporate performance have significant positive regulatory effect.
