企业战略差异度会影响分析师盈余预测吗？

随着我国资本市场的发展,证券分析师的作用日益凸显,关于分析师盈余预测的研究一直是各界关注的重点。采用我国沪深两市A股上市公司2011—2015年分析师盈余预测数据,检验了企业战略差异度对分析师盈余预测精度和分析师跟踪偏好的影响。实证结果表明：（1）企业战略差异度越大,分析师盈余预测准确度越低;（2）企业战略差异度越大,分析师盈余预测分歧度越大;（3）企业战略差异度越大,分析师跟踪人数越少。进一步研究还发现：国有产权会削弱战略差异度对分析师盈余预测准确度和跟踪人数的不利影响。     

Earnings disaggregation and analysts＇ forecasts

Accounting concepts dictate that separately disclosed components should contain separate useful information. This paper examines the relations between income statement components and analysts＇ earnings forecasts and forecast errors. Regressions explaining earnings forecasts using earnings components provide a better fit than regression using just aggregate income to explain forecasts. We interpret this as consistent with the hypothesis that analysts use incremental information in components not available in aggregate income. However, additional tests based on predictability of forecast errors indicate that analysts do not incorporate all information available in components into earnings forecasts. In addition, this inefficiency appears to increase at longer forecast horizons.     

其他综合收益、管理防御与分析师预测

以2009—2013年A股非金融上市公司为研究对象,基于管理防御视角,研究了其他综合收益（OCI）对分析师预测的有用性。研究发现,分析师盈余预测时更充分反映了正值其他综合收益,对负值其他综合收益反映不足;其他综合收益为负值时,分析师会向下修正预测值,且会造成预测误差;而其他综合收益为正值时,却没有向上修正预测值,也没有导致预测误差。进一步研究发现,相对于管理防御程度高的情况,仅在管理防御程度低时,其他综合收益才对分析师预测有用。     

Improvements onthe Earnings Forecast Model——Based on Correlation between Financial Ratio, Auditor Opinion and Future Earnings

This paper aims to find evidence for the improvements on the present earnings forecast models through analyzing the correlation among financial ratios, auditor opinion of listed companies and their future earnings. This paper uses two statistical regression methods including Logistic model and Linear model to examine the inner interaction between financial ratios and future earnings from qualitative and quantitative perspectives respectively. Empirical tests find that financial ratios, especially ROE, can help to predict future earnings. Then we add auditor opinion variable into Logistic model to test whether going concern opinion in the auditor reports can be helpful for earnings forecast. Result shows the degree of optimistic statement of going concern opinion is significantly correlated with future earnings but with the disturbance of earnings management.     

证券分析师跟踪:决定因素与经济后果

以会计信息的价值相关性模型为基础,探讨了分析师跟踪上市公司的决定因素及其对盈余信息价值相关性的影响。研究发现,分析师更倾向于选择盈余平滑程度较高且盈余操纵较少的公司。在分析师市场形成后,投资者将分析师的预测作为估计公司未来盈利的主要依据;对没有分析师跟踪的公司,投资者仍然倾向于运用以往的盈利作为公司未来盈利预测基础。     

Earnings forecasts in enterprise information systems environment

With the globalisation and integration of world financial markets, the application of enterprise information systems has become more and more popular in the financial service sector. This paper examines the analyst's decision regarding allocation of effort to the precision and timeliness of earnings forecasts with financial decision support systems. Once an analyst decides to follow a firm, the analyst must choose the level of effort to devote to generating outputs, such as earnings forecasts. This paper provides insights into this by examining three issues concerning the forecasts of the individual analyst. First, forecast accuracy and frequency are modelled simultaneously. Then, whether these two effort allocation choices are complements or substitutes is tested. Finally, how competition affects these two characteristics is examined. The accuracy and frequency are examined with simultaneous equations. Results from this analysis suggest that analysts allocate effort among these two forecast criteria in a complementary way. Finally, empirical results reveal a positive association between competition and forecast frequency by the individual analyst. However, a significant association between competition and the individual analyst's forecast accuracy is not found.     

资产减值与会计盈余稳健性的实证分析

本文考察了我国近年来资产减值会计制度的变迁对会计盈余稳健性造成的影响。研究发现,尽管存在较大的盈余管理空间,但我国资产减值会计制度的不断强化促进了更加稳健的会计盈余,并且盈利公司会计盈余的稳健程度高于亏损公司。表明资产减值会计制度的改革在提高会计信息质量方面是有效率的。

证券分析师业绩预测和投资评级准确性实证分析

文章以国内证券分析师业的业绩预测和投资评级为研究对象,从投资评级的准确性、投资建议赢利性、业绩预测误差及其来源等几个方面进行了实证分析。研究结果表明,证券分析师的投资建议无论在短期还是中长期均不能产生显著的超额收益,业绩预测误差是导致投资评级失误的原因之一,而业绩预测误差主要源于分析师对公司层面信息的错误判断。

盈余管理的概念及辨析

本文对盈余管理的概念作了界定,并对相关的概念——会计政策选择和财务舞弊作了辨析。本文认为,盈余管理是在法律和会计准则的范围内进行的,其方法主要是会计方法,但也包括非会计方法。盈余管理与会计政策选择的主要区别在于实施盈余管理的企业管理当局有操纵盈余的动机,而盈余管理与财务舞弊的区别在其合法性上。     

年报核心竞争力信息披露具有信息含量吗？——基于分析师视角

以2012—2018年A股上市公司为研究对象,实证检验年报核心竞争力信息披露的信息含量。实证结果表明：年报核心竞争力信息披露长度与分析师盈余预测准确度无关,但年报核心竞争力信息披露中的特质性信息却与分析师盈余预测准确度相关;在非国有企业以及公司治理较强的企业中,核心竞争力信息披露更有利于提高分析师盈余预测准确度;核心竞争力信息披露与公司盈余具有相关性,因而有利于提高分析师盈余预测准确度;分析师盈余预测准确度与公司和同行业核心竞争力信息披露的相似度相关,而与公司当年和上一年核心竞争力信息披露的相似度无关。     

The effect of earnings forecast precision on firm value and insider trading under voluntary disclosure in Taiwan

Taiwan changed its earnings forecast policy from mandatory to voluntary disclosure in 2005. In this study, the inferences of voluntary earnings forecast are examined based on forecasts issued by listed firms. This study suspects that insiders have a temptation to strategically manipulate financial forecast information to influence markets and thus receive extra rents. Under the new earnings forecast disclosure policy, the number of disclosing firm decreases but the precision of earnings forecast increases. The empirical result from dynamic panel data evidences the forecast error of voluntary disclosure may negatively impact firm values. Furthermore, there is a positive relationship between insiders＇ trading profit and manipulation of earnings forecasts. As volatility in insider manipulation increases, it is difficult for the investors to predict the real intention of insiders, and insiders may achieve greater benefits from trading. This study also observes that many listed companies hold investor conferences to provide earnings guidance in Taiwan. The reason may be that investor conference is more flexible and has less forecast error cost than the formal financial forecast. This study provides important insights into earnings forecast policy in emerging markets. The competent authority should improve corporate governance and develop monitoring functions to abate forecast manipulation.

信息分享对原始设备制造商与其合同制造商竞争的影响

研究了原始设备制造商的预测信息分享对一个原始设备制造商和一个与其同时有合作和竞争的合同制造商组成的供应链系统的影响,建立制造商间信息分享的模型,该模型包括一个原始设备制造商和一个合同制造商。研究发现,原始设备制造商关于市场潜在需求预测信息的分享对其预期利润是不利的,同时需求信息预测的精度对原始设备制造商信息分享的决策也有影响,原始设备制造商没有动机与其供应链成员进行信息分享,但信息分享使得供应链整体利润增加。最后,建立一个信息分享补偿机制分享供应链利润的增加量,以期通过信息分享补偿机制促使原始设备制造商有动机进行信息分享,从而实现其与合同制造商的“双赢”。

定向增发下证券分析师评级乐观性研究

定向增发是目前上市公司股权再融资的重要手段,受到了资本市场的广泛关注。以我国2013—2015年A股市场的定向增发股票为研究样本,分别从外部环境影响角度和分析师自身角度实证分析分析师股票评级乐观性倾向的影响因素,结果表明：承销关系、分析师声誉和分析师盈利预测的乐观性与分析师评级乐观性正相关,而声誉高、规模大的券商以及分析师的努力程度则会对其评级的乐观倾向产生反向抑制作用。分析师评级报告发布日距定增报告公布日的时间间隔也会对分析师评级乐观性产生负向影响,但这种影响并不显著。
