境外上市对公司盈余管理的影响及其路径研究

境外上市能否促进企业会计信息质量的提升尚无定论，本文以盈余质量衡量企业的会计信息质量，研究结论支持境外上市能有效提高公司的盈余质量和减少盈余管理现象，支持绑定理论对中国境外上市企业成立。本文进一步探讨绑定理论发挥效果的具体路径，通过对内部公司治理因素和外部投资者监督因素的分析，发现内部因素（审计委员会人数和聘请会计师事务所质量）和外部因素（分析师覆盖率）均对盈余质量的提高有显著影响，以此表明绑定效应是通过法律监督和外部市场监督两个方面同时发挥作用，内部动因和外部压力均会产生绑定效应。

On the Impact of Cross-listing on Earnings Management and Transmission Channel

It is inconclusive about the effect of cross-listing on the increase in accounting information quality. This paper takes earnings quality as the indicator of accounting information quality and confirms the significant effects of cross-listing on the increase in earnings quality and the decrease in earnings management and the application of the bonding theory into Chinese cross-listed companies. It further discusses the specific routes of the function of the bonding theory. By the analysis of factors of internal corporate governance and external investors supervision, it arrives at the conclusion that internal factors such as the number of audit committee and the quality of accounting firms and external factors like analyst coverage have significant effects on the increase in earnings quality, showing that the bonding effect plays a role through legal supervision and external market supervision, and internal motiva- tion and external pressure have bondin~ effects.
