资本市场开放与企业真实盈余管理——基于“陆港通”的经验证据

资本市场开放不仅是扩大国际融资、更好地利用国际金融市场的需要,而且对我国资本市场发育和上市公司行为具有多重外部治理效应。本文借助我国内地与香港资本市场互联互通机制这一准自然实验,研究资本市场开放对企业真实盈余管理的影响。研究发现:(1)总体上,“陆港通”机制的实施显著降低了标的公司真实盈余管理程度。(2)委托代理问题是企业进行盈余管理的重要原因,而“陆港通”机制开通后,能够缓解标的公司代理矛盾,进而约束管理层的真实盈余管理行为。(3)当资本市场信息环境改善、管理层面临较大股票抛售压力以及大股东监督力度较强时,“陆港通”抑制企业真实盈余管理行为的治理效果更强。本文结果表明,资本市场开放有助于提高我国上市公司财务信息披露质量及公司治理水平。

会计准则变迁、公司治理对盈余管理的影响分析——基于结构方程模型的实证研究

本文应用结构方程模型分析了2006年新会计准则实施前后会计准则变迁和公司治理对盈余管理的共同作用。结果表明:会计准则的应用仅改变了上市公司盈余管理的具体方法如从固定资产减值准备转回改为构造债务重组收入,却无法从总体上约束这些企业的盈余管理行为。且新会计准则实行后的2007-2009会计年度,上市公司的盈余质量有降低趋势,但对亏损公司调减利润的行为有改进。     

公司治理、盈余管理与企业成长

我国上市公司在治理结构方面的缺陷使得资本市场上盈余管理成为一种普遍现象,对公司的发展造成不利的影响。公司治理与盈余管理负相关,与企业增长正相关,而盈余管理与企业增长负相关。     

Corporate governance practices in emerging markets: The case of GCC countries

This paper examines the corporate governance (CG) practices in emerging markets with special reference to the listed firms in the Gulf Cooperation Council's (GCC) oil rich countries. It develops an un-weighted Corporate Governance Index (CGI) model for non-financial firms using recent data. The usefulness of the model is demonstrated with a specific country example. The index identifies thirty internal governance attributes which are abridged in three categories of all the selected firms to form the best CG practices in the region. The results demonstrate that GCC companies adhere to 69% of the attributes addressed in the CGI. The results also show that the firms listed in the United Arab Emirates stock markets exhibit the best adherence to the CG attributes examined in the study followed by Oman, Saudi Arabia, Qatar and Kuwait, respectively. The current paper offers valuable recommendations to policy makers to gradually embed strong and specific governance practices. Special emphasis is placed to board effectiveness and structural and organizational frameworks in order to ensure a sustainable quality of CG practices in the region.     

盈余管理的实证研究综述

盈余管理的实证研究渐亦成为盈余管理研究的主要方面,而实证研究的具体内容却极其庞杂。通过对国内外学者盈余管理实证研究具体内容的探寻,进而发现盈余管理实证研究的发展趋势。盈余管理的实证研究内容正在从早期的专注于盈余管理动机手段等向注重于盈余管理与会计政策、关联交易、公司治理、审计、企业并购的关系等具体方面发展。     

中国证券市场机构投资者与上市公司盈余管理关联性的研究

本研究从中国证券市场机构投资者与上市公司盈余管理之间关系这一视角出发,来说明机构投资者在公司治理中的作用,通过对相关理论的归纳和分析,构建了研究假设,在此基础上,利用中国上市公司数据,设计实证模型,对研究假设进行了论证.研究发现了在中国证券市场当机构投资者持股比例高时抑制盈余管理,机构持股比例低时加剧盈余管理,即倒U型的关系。研究应用截面数据分析、面板数据分析、单变量分析等方法,从2005年和2007年的数据验证出倒U型的拐点在机构持股6%,说明机构持股6%以后,在公司治理中发挥了抑制操纵盈余的盈余管理的积极作用。利用2004～2007年的数据,进一步的研究发现,随着近年机构投资者的发展和国家的政策导向,机构投资者对盈余管理的抑制作用越来越强,在公司治理中越来越显示出重要的作用。     

Adverse selection and corporate governance

This paper examines the impact of corporate governance on the adverse selection component of the bid-ask spread of stocks listed on the Singapore Exchange. These companies have been identified by Credit Lyonnais Securities Asia (CSLA) with the highest level of corporate governance among 25 emerging markets. We measure corporate governance by several criteria: discipline, transparency, independence, accountability, responsibilities, fairness, and social awareness. The results show that corporate governance has an inverse relationship with adverse selection. However, only the transparency dimension exhibits a significant inverse relationship with adverse selection. In addition, Government-Linked Companies (GLCs) are shown to have a smaller adverse selection component than non-GLCs.     

Bank Deregulation, Supervision, and Agency Problems

This article argues that the financial instability of the 1980s following financial deregulation in Australia can be partly traced to a lack of attention to agency problems in banking. Because the market for corporate control and corporate governance structures in banking were unsatisfactory, the benefits of increased competition in financial product markets were offset by inadequate monitoring and controls on bank management. It is also argued that the current emphasis of prudential supervision on capital adequacy requirements can provide only a partial solution to achieving efficiency and stability in the financial sector—because it focuses only upon the agency relationships between owners and government/depositors. Complementary developments in corporate governance and control are required to address agency relationships involving bank management. Some recent developments in this area and in supervision of non-bank financial markets are assessed from the perspective developed in this article.     

机构投资者持股和会计盈余质量

本文从会计盈余质量的角度来研究机构投资者(’在公司治理中的作用。我们从盈余管理程度、盈余信息含量和盈余稳健性等三个方面来衡量会计盈余的质量。三方面的研究结果显示,机构投资者持股有助于改善会计盈余的质量:机构投资者持股公司的会计盈余质量显著高于其他公司,并且会计盈余的质量随着机构投资者持股比例的增加而增加。进一步研究发现,机构投资者还能够缓解大股东对会计盈余信息含量的恶化,起到一定的制衡作用。本文的研究表明,机构投资者能够在一定程度上改善上市公司的盈余质量,其快速成长有助于公司治理结构的改善,也有助于资本市场信息披露环境的良性发展。     

The frequency and magnitude of earnings management in China

Earnings management is an indicator of the corporate governance quality and investor protection standard. We study the frequencies and magnitudes of earnings management under two different thresholds, zero earnings and prior earnings, in the Chinese market from 1997 to 2004. We model earnings as a mixed-normal distribution and obtain parameter estimators that measure the frequency and magnitude of earnings management. We show that the practice of earnings management has gone up both in frequency and magnitude during the post-2000 period. We also find that the frequency and magnitude of earnings management are higher when firms try to avoid negative earnings than when firms try to report earnings increase. Our findings reflect the current economic environment in China and caution investors on the low-disclosure quality in the Chinese stock market.     

公司治理、现金股利变化与盈余变化持续性——基于中国上市公司的分析

考察了中国上市公司治理结构、现金股利变化与盈余变化持续性之间的关系。研究发现,现金股利变化对盈余变化持续性的影响有类似成熟资本市场所呈现的预测作用,但作用较弱;而且这种预测作用的强弱受到公司治理结构的影响;现金股利变化对盈余变化持续性的预测作用表现直接,并非通过股利变化的市场反应表现出来。该结论为市场参与者客观准确地判断上市公司业绩及其投资价值提供了良好的参考。     

第一大股东对公司治理、企业业绩的影响分析

本文以 1 997年以前在中国上市的 50 8个上市公司 1 997— 2 0 0 0年 4年间的2 0 3 2个观察值为样本 ,研究了第一大股东的所有权性质、第一大股东的变更对公司治理效力和企业业绩的影响。本文的研究发现 ,上市公司第一大股东的所有权性质不同 ,其公司业绩、股权结构和治理效力也不同。第一大股东为非国家股股东的公司有着更高的企业价值和更强的盈利能力 ,在经营上更具灵活性 ,公司治理的效力更高 ,其高级管理层也面临着更多的来自企业内部和市场的监督和激励。另外 ,本文的研究还发现 ,对于不同性质的公司 ,第一大股东的变更带来的影响也有所不同 ,但基本上都是正面的。第一大股东的变更有利于公司治理效力的提高 ,有利于公司规模的扩大和管理的更加专业化。本文的研究为国有股减持和股权多元化提供了经验证据 ,论证了控制权转移市场对深化改革和完善公司治理的重要性     

公司治理结构与盈余管理研究——基于我国ST公司的经验证据

本文以我国ST上市公司为研究样本．从股权结构、董事会和监事会方面，对盈余管理与公司治理结构之间的关系进行了实证分析。结果表明．流通股与盈余管理无相关关系．股权集中度与盈余管理正相关．独立董事与盈余管理负相关。此外．由于我国股权结构相对比较集中．致使股权制衡度与盈余管理正相关．没有发挥其约束作用。这些结果表明．股权适度集中．有相对控股权的大股东的公司盈余管理较轻．治理效果较好。     

公司治理视角的中国上市公司盈余管理研究

盈余管理是一个令全球投资者和政府关注,但一直未能得到有效解决的问题。使用修正的Jones模型对1999—2010年中国上市公司的盈余管理进行估计,可以看出中国上市公司存在较为严重的盈余管理,盈余水平与总资产之比的平均值为7．6％左右。对公司治理变量与盈余管理之间关系作进一步的实证研究发现,第一大股东持股比例对盈余管理存在显著的正向影响,第二到第十大股东持股比例和高管持股比例对盈余管理的影响显著为负;民营控股企业进行盈余管理的倾向高于国有控股企业。这些结果意味着,中国需进一步完善上市公司治理机制,降低盈余管理的幅度。     

Directors network centrality and earnings quality

This study examines whether firms with network central boards of directors behave differently from other firms in terms of financial reporting quality. We find that earnings quality among firms is low when board networks are channels of incorrect information transmission (including earnings management information) and for firms whose directors are awarded equity-based compensation have connections through boardroom networks, but earnings quality is better for firms with good performance in spite of their networks. These results are robust to controlling for firm information environment, growth, size, age, leverage, performance, volatility in firm operations, and corporate governance.     

Compliance and multidimensional firm performance: Evaluating the efficacy of rule-based code of corporate governance

This study seeks to evaluate the efficacy of the Pakistani Code of Corporate Governance by finding out its impact on firm's performance and efficiency. This exploration is done in the context that Securities & Exchange Commission of Pakistan's choice of corporate governance regulations is heavily influenced by Anglo-Saxon approach, whereas de-facto realities of Pakistani corporate environment are quite in contrast.Using a panel data of 119 firms for the period of 8 years i.e. 2003 to 2010, and using a multidimensional performance framework i.e. financial performance and technical efficiency, we find that the extent of compliance has increased since the issuance of code in 2002. After controlling for firm size, growth, dividend payout, age and leverage, we find significant positive impact of compliance on firm's performance (ROA, ROE and ROCE). We also find a weak positive relationship between compliance and technical efficiency. We suggest that compliance is not linearly related with financial performance and we find that high compliant firms are less profitable than average or low compliant firms. This implies that one-size-fit all approach along with mandatory compliance is a questionable approach for Pakistani firms.This study is first in Pakistan in providing empirical evidence on efficacy of the rule-based Code of Corporate Governance and also adds to growing but underdeveloped literature on compliance and firm performance in emerging/developing economies. Further, this study offers insight to policy makers on the efficacy of current corporate governance regulations and offers a research framework for assessing the extent of compliance, effectiveness and economic impact of code of corporate governance.     

Debt markets and corporate debt structure in an emerging market: The South African example

This is a first attempt at gauging the effects of corporate public debt issuance on the debt structure, risk profile and valuation of firms in an emerging market. We find that financial services firms, along with government institutions, are important early supporters of an organized public debt market. Firms in this market use equity, public debt and private debt funds simultaneously as need be. Consistent with predictions of the corporate debt structure literature, public debt-issuing firms are larger, older, more profitable, and less informational opaque than non-public debt-issuing firms. Moreover, public debt-issuing firms experience significant reductions in both overall and systematic risks, and incur lower cost of capital following issuance than non-public debt issuers. These and other findings of the study suggest deepening national debt markets can be a fruitful financial market development exercise for emerging markets.     

数字经济能否缓解管理层短视行为?——来自真实盈余管理的经验证据

管理层短视行为是学术界和管理实践关注的焦点。数字经济究竟对管理层短视行为有何种影响尚无明确结论。本文以表征公司短视行为的核心变量真实盈余管理为研究情境,检验数字经济对真实盈余管理的作用及影响机制。研究发现:数字经济显著抑制真实盈余管理,缓解了管理层短视行为。中介机制的检验结果表明:数字经济通过降低委托人和代理人之间的信息不对称程度和缓解融资约束两条路径抑制真实盈余管理。进一步研究显示,公司所处行业的市场竞争程度越激烈,数字经济越能在信息流传递层面“精准施治”,抑制真实盈余管理的效果越显著。本研究明晰了数字经济对微观公司治理领域的影响,为解决管理层短视行为,抑制真实盈余管理提供了重要的经验证据和理论启示。     

Trade openness and the informational efficiency of emerging stock markets

This paper examines the empirical link between trade openness and the informational efficiency of stock markets in 23 developing countries. Our fixed effects panel regression results document a significant negative relation between trade openness and stock return autocorrelations only when the de facto measure is used. On this basis, we argue that a greater level of de facto trade openness is associated with a higher degree of informational efficiency in these emerging stock markets because the former signals higher future firm profitability, and investors tend to react faster to information when there is less uncertainty about a firm's future earnings or cash flows. Further analyses find no significant association between the extent of financial openness and the degree of informational efficiency.
