传闻消息对我国上市公司股价影响的实证分析

本文通过有关我国上市公司的传闻消息对上市公司股价影响的实证分析,得出在消息公布日前2天以及后3天的时间段里,传闻消息对股价有正影响,从而给投机者带来了非正常收益,但是从长期来看,传闻消息不会给投资者带来任何非正常收益。另外,通过对各类传闻消息对股价影响的进一步分析,发现在诸类传闻消息中,主力类传闻对上市公司股价的影响最为显著,能给投机者带来很大的非正常收益。     

上市公司收益质量评价问题的探讨

收益是衡量企业经营情况、盈利能力以及未来发展前景的一个重要指标,能否真实公允地评价一个企业的收益状况对于投资者的投资决策,经营者的经营管理,供应商对回收货款风险的判断以及债券人的信贷决策都有着重大影响.本文从影响上市公司收益质量的影响因素出发,分析了上市公司进行收益质量评价时应注意的问题,进而提出上市公司收益质量评价的主要方法.     

对《信息披露、收益不透明度与权益资本成本》一文的评论

黄娟娟和肖珉的论文《信息披露、收益不透明度与权益资本成本》(以下简称信文)以1993年至2001年间我国证券市场进行股权再融资的上市公司为样本,考察了我国证券市场上市公司信息披露质量与公司权益资本成本的关系。作者发现,在控制其他一些影响因素之后,上市公司信息披露质量与公司权益资本成本呈显著的负相关关系。而且,上市公司权益资本成本不仅受到前一年     

其他综合收益的列报会提高上市公司的市盈率吗?

其他综合收益与净利润一起构成企业的综合收益,综合收益观是收益报告的主流趋势.通过分析,我们认为列报其他综合收益,有利于提高会计信息透明度、提升会计信息质量,抑制企业盈余管理行为,帮助委托人了解受托责任履行情况和财务报告使用者预测企业未来收益做出决策.这与财务报告目标的受托责任观和决策有用观也是一致的,进而提高投资者对公司股票的信心,促进上市公司市盈率的提高.     

股权结构、行业管制与收益平滑——基于中国A股上市公司的经验证据

本文利用2003—2009年我国A股上市公司为样本,考察上市公司收益平滑的存在性,然后对影响上市公司收益平滑的因素作实证分析。在对收益平滑的影响因素考察中发现,股权集中度假说、股权制衡度假说均通过了检验,而行业管制假说没有通过检验。这说明,在我国A股上市公司中,第一大股东持股比例越高、第一大股东与第二大至第十大股东持股比例之比越低更有可能进行收益平滑。     

其他综合收益的列报与披露——基于上市公司2009年年度财务报告的分析

财政部在《企业会计准则解释第3号》和《关于执行会计准则的上市公司和非上市企业做好2009年年报工作的通知》中引入了其他综合收益的概念,同时对利润表、所有者权益变动表格式进行了相应调整,并要求上市公司于2009年1月1日起执行。本文将在探讨其他综合收益的实质和具体项目界定标准的基础上,通过对上市公司2009年年报其他综合收益列报与披露情况的分析,总结其他综合收益披露存在的主要问题,并就此提出建议,以益于提高上市公司其他综合收益披露的信息质量。     

我国每股收益中配股问题探讨

<正>从2007年1月1日起实施的新会计准则对每股收益的计算和披露进行了重大调整,使每股收益披露模式从"摊薄-加权"演进为"基本-稀释"模式,对上市公司的财务报表的披露产生了重大影响。为了使每股收益指标能够更真实准确的反映财务信息,下面结合我国上市公司的配股问题来分析每股收益的计算,为其完善提出更好的建议。     

我国上市公司的收益质量分析

本文是通过对收益质量的概念和特征的分析,研究得出影响上市公司收益质量的因素以及如何对收益质量来进行评估。根据问题,分析产生问题的原因,提出相对应的解决对策。     

海润光伏股份有限公司收益质量分析

上世纪末开始,国内外资本市场频频曝出上市公司财务丑闻,使利益相关者逐渐意识到上市公司收益质量的重要性,相关研究也日益受到国内外学术界重视。本文以海润光伏股份有限公司作为研究对象,选取2013~2015年财务数据,从成长性、稳定性、现金保障性、持续性、安全性五方面分析了海润光伏的收益质量,然后对公司管理层和投资者提出建议。     

市场化程度、股权结构与IPO时的无形资产剥离

以1993至2009年上市公司IPO过程中无形资产的剥离和付费信息为基础,本文分析了IPO时资产重组的影响因素及其经济后果。我们的研究发现,大股东后续获取控制权收益的成本越低,就越有可能在IPO时保留无形资产的所有权,并在IPO后安排更多与之相关的关联交易。本文的研究结果表明,大股东在IPO时和上市后如何从上市公司获取收益最终都取决于其获取控制权收益的成本,因此,保护中小股东的利益要从完善制度环境、改善公司治理以提高大股东获取控制权收益的成本入手。     

Corporate social responsibility and earnings forecasting unbiasedness

We investigate the relationship between corporate social responsibility (CSR) and I/B/E/S analysts’ earnings per share (EPS) forecasts using a large sample of US firms for 1992–2011. Based on literature findings, we decompose the CSR effect into four factors: accounting opacity, corporate governance, stakeholder risk, and overinvestment. We find that all of them significantly affect both the absolute forecast error on EPS and its standard deviation controlling for forecast horizon; number of analysts and forecasts; and year, industry, and broker house effects. Consistently with our ex ante hypotheses, overinvestment, stakeholder risk, and accounting opacity have a positive effect, increasing both dependent variables, while corporate governance quality has a negative effect. A crucial aspect of our findings is that high CSR quality in terms of the four factors (i.e., accounting transparency, high corporate governance quality, stakeholder risk mitigation, and absence of overinvestment) contributes to making earnings forecasts unbiased as unbiasedness is generally met in the subsample of the Top CSR quality companies and markedly violated in the subsample of the Bottom CSR companies. We also document that overinvestment and stakeholder risk are sufficient to produce this effect.     

The Effect on Financial Reporting Quality of an Exemption from the SEC Reporting Requirements for Foreign Private Issuers

We test for differences in financial reporting quality between companies that are required to file periodically with the SEC and those that are exempted from filing reports with the SEC under Rule 12g3-2(b). We examine three earnings quality measures: conservatism, abnormal accruals, and the predictability of earnings. Our results, for all three measures, show different financial reporting quality for companies that file with the SEC than for companies exempt from the filing requirements. This paper provides empirical evidence of a link between filing with the SEC and financial reporting quality for foreign firms.     

资产减值:稳健性还是盈余管理

本文研究了我国上市公司资产减值的计提动机。很多研究已发现减值准备的两种计提动机:经济因素和盈余管理因素,但本文发现,稳健性因素也能影响资产减值准备的计提。在同样的毁损情况下,"坏消息"公司将比"好消息"公司计提更多的减值准备。此外,本文还发现,在利用减值准备进行利润操纵时,盈余管理动机的不同会影响减值类型的选择。扭亏和大清洗公司会采取各种类型减值准备进行盈余管理,而平滑和管理层变更公司只使用长期资产减值准备,而且是不影响营业利润的减值准备。     

Do corporate governance recommendations improve the performance and accountability of small listed companies?

This study examines whether the implementation of the 2003 Australian Securities Exchange Limited governance recommendations influenced the governance choices of small companies and whether compliance improves their accounting and market performance and earnings quality. Our analysis examines small and large companies because we are interested in the different effects of the governance recommendations on the two groups. The analysis shows a significant shift by small and large companies to comply with the recommendations around the time of their introduction. We find that formation of an audit committee surrounding the reform period is significantly associated with improved earnings quality for small and large companies. However, compliance with other governance recommendations is not systematically associated with improved performance or earnings quality.     

盈余管理、盈余管理属性与审计意见——基于中国证券市场的经验证据

过去的文献一直把盈余管理看成同质风险,而本文把盈余管理按属性划分为决策有用性盈余管理和机会主义盈余管理,采用1999年至2008年A股上市公司作为研究样本,研究了审计师能否对不同属性的盈余管理做出差别反应,并表现在审计意见决策上。研究结果发现,在同样进行了盈余管理的样本中,审计师能够区分不同属性的盈余管理,对高风险的机会主义盈余管理应计额出具非标意见的概率大于低风险的决策有用性盈余管理的应计额。     

Economic policy uncertainty and bank earnings opacity

Using a sample of U.S. banks and an index for economic policy uncertainty developed by Baker et al. (2016), we investigate whether economic policy uncertainty is systematically related to bank earnings opacity. When economic policy is relatively uncertain, it is easier for bank managers to distort financial information, as unpredictable economic policy changes make assessing the existence and impact of hidden “adverse news” more difficult for investors and creditors. Economic policy uncertainty also increases the fluctuation in banks’ earnings and cash flows, thus providing additional incentives and opportunities for bank managers to engage in earnings management. Our results show that uncertainty in economic policy is positively related to earnings opacity, proxied by the magnitude of discretionary loan loss provisions and the likelihood of just meeting or beating the prior year’s earnings, and negatively related to the level of accounting conservatism (i.e., the timeliness of recognition of bad news relative to good news). Collectively, our results suggest that economic policy uncertainty leads to greater earnings opacity. We also find that the impact of economic policy uncertainty on financial reporting distortion is less pronounced for stronger banks (i.e., banks with high capital ratios).     

业绩快报的信息含量:经验证据与政策含义

业绩快报是上市公司2004年报披露中的一项制度创新。本文旨在研究业绩快报是否具有信息含量,以及业绩快报的披露是否会减少盈利公告的有用性。我们选取了2005年1月至4月间披露的70份2004年度业绩快报作为样本进行了实证研究。研究结果表明:业绩快报的披露提高了会计信息质量;业绩快报具有显著信息含量;业绩快报的披露并没有减少盈利公告的信息含量,是盈利公告的一种有益补充形式,值得提倡和推广。     

Timing earnings

Since the opening of China’s securities market, there have been a number of bull and bear cycles. This paper discusses how executives use the market timing approach to manage earnings in different cycles to maximize firm value. We find that Chinese listed companies choose to release more earnings during bull markets and this phenomenon is more evident in companies that are more profitable and have higher valuations. We also find that executives who do not release more earnings during bull markets are more likely to be dismissed.     

Where do firms manage earnings?

Despite decades of research on how, why, and when companies manage earnings, there is a paucity of evidence about the geographic location of earnings management within multinational firms. In this study, we examine where companies manage earnings using a sample of 2,067 U.S. multinational firms from 1994 to 2009. We predict and find that firms with extensive foreign operations in weak rule of law countries have more foreign earnings management than companies with subsidiaries in locations where the rule of law is strong. We also find some evidence that profitable firms with extensive tax haven subsidiaries manage earnings more than other firms and that the earnings management is concentrated in foreign income. Apart from these results, we find that most earnings management takes place in domestic income, not foreign income.     

私募股权资本与创业板企业上市前盈余管理

本文考察了私募股权资本对我国创业板企业上市前盈余管理活动的影响,对私募股权投资者进行了界定和区分,采用多种指标衡量盈余管理程度,用工具变量两阶段回归等方法控制自选择偏差。研究发现,根据持股时间不同划分的长、短期私募股权资本对企业上市前盈余管理行为影响的方向和程度均不相同,长期持股的PE机构显著降低了企业的盈余管理程度;相反,上市前一年内突击入股的PE机构显著增加了企业的盈余管理程度。这种不同PE机构对企业创业板上市前盈余管理行为的差异化影响,在创业板的一级市场和二级市场上已被投资者给予区分。本文进而提出了政策建议。
