    会计报告的盈余信息(每股收益)是判断股票是否具有投资价值的重要指标,即便是具有相同盈余数字的上市公司,其股价(或股票收益率)也存在或大或小的差异,投资者在进行分析时除了关注盈余信息之外,还应关注财务报表中的基本面信息。通过分析基本面信息对盈余反应系数的影响,可以考察基本面信息在评价上市公司盈余质量中所起的作用。实证研究结果表明,基本面信息可以在一定程度上反映盈余质量,而依据基本面信息构建的盈余质量综合评价指标(EQ)可以作为评价上市公司盈余质量的参考标准

    Earnings Management and Investment Decisions:From the Perspectives of Accrual-Based and Real Earnings Management

    【中文摘要】本文以2004~2013年度中国A股主板非金融类上市公司为研究对象,从应计盈余管理和真实盈余管理的视角,着重考察真实活动盈余管理和应计项目盈余管理对企业投资决策的影响作用。研究结果揭示,经理人真实活动盈余管理会促使企业在当期,甚至下一期进行更多的过度投资活动;而应计项目盈余管理缓解了企业投资不足的问题。进一步的研究还发现,企业会计期末的异常销售行为和延迟可操控性费用记入当期这两种真实活动盈余管理对投资过度具有显著的影响。本文的研究结论在一定程度上说明,在中国资本市场的背景下真实活动盈余管理直接促使企业管理层做出投资过度的决策;而应计项目盈余管理则通过影响企业外部信息环境间接缓解了企业投资不足的问题。该研究结论扩展人们关于真实活动盈余管理对企业投资决策影响的认识,丰富真实活动盈余管理的经济后果方面的文献,也提供关于真实活动盈余管理对企业预期经营业绩带来负面影响的另外一种解释。 【Abstract】Based on a sample of listed Chinese companies from 2004 to 2013, this study investigates whether real earnings management activities may influence investment decisions.The result suggests that real earnings management may result in enterprises’ overinvestments.Specifically, this paper finds that the increased abnormal sales and the deferred discretionary expense may lead to overinvestment decisions. On the other hand, accrual-based earnings management may reduce enterprises’ under-investments. In sum, we argue that different ways of earnings management may have different impacts on enterprises’ investment decision process. Hence, this study sheds light on the economic consequences of real earnings management.国家自然科学基金项目“制度环境、公司治理与投资效率”(71262018)的阶段性成果。 云南财经大学科学研究基金项目“产权性质、盈余管理策略与非效率投资”和云南省创新团队“云南省公司治理研究”项目的资助
