【摘要】 本论文探讨了我国经济发展中出现的一个重要问题——上市公司的盈余管理行为以及由此引发的会计信息失真现象。证券市场在我国经济中起着越来越重要的作用。上市公司是证券市场的主要组成部分，上市公司对外提供的财务报告成为投资者等利益关系人作决策的重要依据。在证券监管部门评价上市公司的经营业绩时也常常将净资产收益率（ROE）等财务指标作为主要的参考标准。盈余信息在证券市场上具有重要的信号作用。过度的盈余管理会造成严重的经济后果。为了达到配股等目的，管理当局积极的采取各种盈余管理措施，使盈余信息遭到扭曲，误导资源的流向。盈余管理广泛的存在于各国的证券市场上，本文将中美两国证券市场上的盈余管理现象进行对比，分析得出两国盈余管理在动机、方式、手段等方面的异同，并进行了背景分析。论文从应计会计制和委托代理关系等角度，从理论上分析了盈余管理产生的内在原因。然后从制度经济学等角度分析了制度安排中存在的激励和约束因素，得出影响盈余管理行为的主要因素。论文在研究原有的盈余管理识别模型的基础上，通过引进新的盈利预期模型，提出了新的盈余管理识别模型。尽管上市公司进行盈余管理的目的有所不同，但是他们一定有一些共同特征。因此，本文对实施盈余管理行为的上市公司进行实证分析，得出了一些初步的结论。在最后，提出了笔者的一些旨在弱化过度的盈余管理的建议。本文发现：①盈余管理存在于各个证券市场。在不同的环境下，盈余管理有一定的共性，也表现出不同的动因和手段。②由于应计会计制和委托代理关系等因素的存在，盈余管理是不可能完全杜绝的。③现行制度安排中存在盈余管理行为的激励因素和约束因素，但是约束因素的作用很弱，因此上市公司管理当局倾向于实施盈余管理行为。④实证研究确实发现在有盈余管理行为的上市公司中存在一些共同的特征。更多还原
