中文摘要：

本文以2007—2009年发生控制权转移的公司为样本，采用截面Jones模型、DD模型、真实盈余管理模型计算控制权转移公司的盈余管理。研究发现，尽管市场环境（股权分置改革、会计准则）发生改变，上市公司控制权转移中仍然普遍存在盈余管理行为，控制权转移公司的盈余管理程度较高。进一步分析控制权转移特征后发现，协议转让的公司、最终控制人发生变化的公司、董事长发生变更的公司更偏好盈余管理。

英文摘要：

This paper uses Jones model and DD model to measure accrual earnings management and the model applied in Roychowdhury （2006） to measure real earnings management in the sample period of 2007-2009. It＇s found that earnings manipulation still exists in control right transfer and earnings are more manipulated in companies with control right transfer despite of changes in capital market structure and accounting standards. Further study finds that earnings management is preferred by companies with negotiation transfer, ultimate owner changes or chairman changes of the board.
