【摘要】 随着我国资本市场和会计市场的发展，目前有关上市公司盈余管理的问题已引起了前所未有的重视。 盈余管理是为了获得个人利益而对企业财务报告进行有目的的干涉，实际上是对上市公司所披露的会计信息的操纵，盈余管理行为会引起企业各个契约关系人之间财富的重新分配，甚至会引起他们之间新的利益冲突。加上过分的盈余管理行为很容易演变成舞弊、欺诈、内幕交易。在我国资本市场的发展历程中，诸如琼民源、郑白文、银广夏、麦可特等恶性事件时有发生，上市公司披露的会计信息是否真实?有无操纵盈余的问题?如何解决?这些问题一方面直接关系到证券市场能否有效发挥资源配置的功能，而且反映出政府监管政策的合理性以及能否保证我国证券市场健康、稳定、持续的发展。这不仅仅是一个单纯的经济问题，而且也是一个严肃的社会政治问题。因而，对中国上市公司盈余管理问题进行研究就显得十分必要和迫切。 本文采用实证研究的方法，选择中国A股上市公司1998—2000年度的净资产收益率(ROE)作为研究对象，对样本分布进行了定量的统计分析和假设检验，从理论和实践相结合的角度系统地论述了上市公司盈余管理形成的机制和实现方式，并对如何进一步健全我国证券市场提出了若干建议。 本文研究形成地结论如下：1．中国A股上市公司1998—2000年度确实存在严重的盈余管理行为并且具有明显的政策导向效应。2．盈余管理形成机制的主要因素包括：委托代理关系、债务契约关系、政治成本假设、非对称信息存在、会计政策选择、会计准则和会计制度的不完善、信息披露制度不完善、上市公司治理结构等。3．盈余管理实现的方式主要有关联交易、资产转让置换、巧用会计政策、资产重组、地方政府支持等。4．建议完善会计准则和会计制度、完善披露关联交易制度、修订暂停上市规定、改进配股资格的控制参数、完善证券市场相关监管政策等。更多还原
