审计质量、产权性质与内部控制——基于中国上市公司的经验证据

对审计质量、产权性质与内部控制的关系进行了研究。结果表明，行业专著程度高的事务所审计与内部控制水平有显著的正相关关系；总体上国有企业比非国有企业的内部控制水平高，但在规模相同的条件下，非国有企业内部控制水平反而更高；与非国有企业相比，经过行业专著程度高的事务所审计的国有企业内部控制水平更高。另外，高质量审计与企业内部控制水平存在自选择问题，在运用处理效应模型控制了自选择偏差后，研究结论依然成立。

Audit Quality, Property Right and Internal Control:Empirical Evidence Based on Chinese Listed Companies

This paper studies the relationship among audit quality, property right and internal control. The research finds that the audit quality of Big 4 and those audit firms with their specialization in an industry has significantly positive correlation with internal control quality. Internal control quality is generally better in the state-controlled listed companies than in the non-state-controlled ones, however, after scale control, i.e. under the condition of the same scale, internal control quality is better in the non-state-controlled listed companies than in the state-controlled ones. The state-controlled listed companies audited by audit firms with specialization in an industry have a better internal control as opposed to the non-state-controlled listed companies. Besides, there is a problem of self selection between high quality auditing and internal control quality. Using the treatment effect model to control the deviation of self selection, the research conclusion is still robust.
