中文摘要：

按照形成原因——作用机理——解决机制的路径,对抑制盈余管理有效途径的实证研究表明：机会主义偏误和技术性错误是盈余管理的主要形成原因,公司治理通过降低代理问题导致的机会主义偏误,能够显著抑制上市公司的盈余管理;内部控制通过降低控制失误导致的机会主义偏误和技术性错误,能够显著抑制上市公司的盈余管理.具体来讲,公司治理和内部控制能够抑制应计盈余管理和真实活动盈余管理,但对酌量性费用操控方式的真实活动盈余管理的影响并不显著.

英文摘要：

Through causes-formation mechanism-solution mechanism, an empirical study on the effective ways of controlling earnings management shows that opportunistic biases and technical errors are the main causes of earnings management. Corporate governance can significantly restrain the earnings management of listed companies by reducing opportunistic biases caused agency problem. And the internal control can significantly restrain the earnings management of listed companies by reducing opportunistic bias and technical error caused by control error. Specifically, we find that corporate governance and internal control can reduce real and accrual-based earnings management, but the influence is not significant on earnings management controlled by discretionary expenses.
