【摘要】 该文将会计差错的发生和更正作为上市公司进行利润操纵的一种信号行为进行研究。从利润操纵存在的根源和客观条件入手，分析上市公司进行会计差错及其更正的原因和动机；然后，以有效市场假说的基本理论和资本资产定价模型为基础，对2001年沪市A股所有进行会计差错更正的上市公司进行会计差错的发生和更正的市场传导效应研究，通过检验发现，公司年度报告披露前后时窗内的股票交易量和股票价格并未存在显著差异。将实证研究分解为会计差错的发生年度和差错的更正年度两部分进行，将在2001年进行了会计差错更正的公司作为实证研究的测试样本，选取与测试样本规模大致相同以及盈余指标相当的公司作为差错更正年度的控制样本，而差错发生年度的控制样本采用剩余挑选法。分别在会计差错的发生年度和差错的更正年度中，通过测试和控制样本的股票交易量、平均超额收益率和累计超额收益率在报表公布日前后各30天的时窗内的检验，说明我国证券市场的投资者对这类信息未予以特别关注，即我国上市公司的会计差错及其更正行为不具有市场传导效应，并进一步从理论上分析了这种现象产生的原因。然后，从动态博弈的观点出发，站在经济学的角度分析上市公司与注册会计师和证券监管机构之间的博弈行动选择，并将博弈结果与前面的实证结果进行比较，分析我国证券市场的实际表现与理论结果不符的原因。最后，文章从提高投资者自身的水平、建立良好的投资者教育体制、营造良好的投资环境以及完善监管体系、加大监管力度、提高监管效率等角度提出防范公司进行利润操纵的几点建议。更多还原

【Abstract】 This article takes the corrections of accounting errors as one of the profit-manipulate. It begins with the root and the objective condition of the profit-manipulate, to analysis the reason and motivation of the corrections of accounting errors. Then, on the base of the effective market content and the CAPM theory, this paper analyses empirically the market conductibility of corrections of accounting errors with all "A" shares in 2001, and discovers there is no difference on stockjobbing amount and price.This paper classifies empirical analysis in two parts: the year of corrections and errors. It takes the corrections of accounting errors in 2001 as studied sample, and takes corporations who have the same unexpected earnings divided assets with studied sample as control sample. In the years of errors and corrections respectively, through the empirical analysis on stockjobbing amount and price, it researches there’s no difference on studied sample and control sample in appointed areas, and the investors of our securities business have no specially attention on these information. On the other word, we validate the corrections of accounting errors have no market conductibility. Later, it analysis the reasons. Afterwards, form the dynamic Game Theory, it gets the action choices between corporations with CPA and supervisory institution. Contrasting this to empirical analysis, it researches the causation of difference.At last, this paper gives some material advice to keep it away.更多还原
