公司特征、外部审计与内部控制信息的自愿披露——基于沪市上市公司2003—2005年年报的经验研究

本文利用沪市非金融业上市公司2003—2005年年度报告中自愿披露的内部控制信息相关数据,立足于公司特征和外部审计角度,针对上市公司自愿披露内部控制信息的决定因素进行了经验研究。研究发现:我国上市公司自愿披露内部控制信息的总体水平较差,但在2003—2005年间有逐年增加的趋势;上市公司是否自愿披露内部控制信息与是否在海外交叉上市、是否聘请"四大"进行外部审计、资产总规模、资产净利率、独立董事人数占董事总人数的百分比显著正相关,与外部审计意见类型显著负相关,与监事会规模、是否设立审计委员会以及样本年度正相关;在影响上市公司内部控制信息自愿披露的因素中,是否海外交叉上市、独立董事占董事总人数百分比和资产净利率是比较一致的显著因素,相对而言,外部审计尚未起到显著的促进作用。     

The extent of corporate governance disclosure and its determinants in a developing market: The case of Egypt

This paper assesses the extent of corporate governance voluntary disclosure and the impact of a comprehensive set of corporate governance (CG) attributes (board composition, board size, CEO duality, director ownership, blockholder ownership and the existence of audit committee) on the extent of corporate governance voluntary disclosure in Egypt. The measurement of disclosure is based on published data created from a checklist developed by the United Nations, which was gathered from a manual review of financial statements and websites of a sample of Egyptian companies listed on Egyptian Stock Exchange (EGX). Although the levels of CG disclosure are found to be minimal, disclosure is high for items that are mandatory under the Egyptian Accounting Standards (EASs). The failure of companies to disclose such information clearly shows some ineffectiveness and inadequacy in the regulatory framework in Egypt. Moreover, the phenomenon of non-compliance may also be attributed to socio-economic factors in Egypt. Therefore, it is expected that Egyptian firms will take a long time to appraise the payback of increased CG disclosure. The findings indicate that that—ceteris paribus—the extent of CG disclosure is (1) lower for companies with duality in position and higher ownership concentration as measured by blockholder ownership; and (2) increases with the proportion of independent directors on the board and firm size. The results of the study support theoretical arguments that companies disclose corporate governance information in order to reduce information asymmetry and agency costs and to improve investor confidence in the reported accounting information. The empirical evidence from this study enhances the understanding of the corporate governance disclosure environment in Egypt as one of the emerging markets in the Middle East.     

Institutional Investor Protection Pressures versus Firm Incentives in the Disclosure of Integrated Reporting

Corporate disclosures aim to decrease the expectation gap between investors, decrease the advantage of informed investors and consequently reduce information asymmetry. However, the existence of higher numbers of companies’ reports makes the decision making of firms’ stakeholders difficult. To avoid these problems, companies have started to disclose integrated reports. Previous studies have observed that this voluntary corporate disclosure is a consequence of large firms’ incentives associated with preventing abnormal earnings. In this paper, we examine whether these internal factors have a lower/higher impact than institutional contracting pressures. Our results are evidence that firms’ incentives are the main determinants of the voluntary disclosure of integrated reports, and we observe that there is a substitutive role between institutional country pressures and firms’ transparency decisions. However, the contracting environment plays a complementary role when firms suffer from lower asymmetry problems.     

Mandatory CSR disclosure,monitoring and investment efficiency: evidence from China

This study investigates the effect of mandatory corporate social responsibility (CSR) disclosure on firms’ investment efficiency in China. Using the CSR regulation that mandates a group of listed firms to disclose stand‐alone CSR reports after 2008 as a natural experiment, we find that firms subject to the mandatory CSR regulation have decreased investment inefficiency subsequent to the mandate, especially in cases of overinvestment. This effect is more pronounced for firms with a control‐ownership wedge, state‐owned enterprises (SOEs), and firms having lower institutional ownership. Further analyses find that the reduction of overinvestment is much more significant in industries with high pollution and that the reduction in investment is not due to the CSR spending siphoning off capital used in other projects. We argue that mandatory corporate social responsibility disclosure improves monitoring over firms in China, especially when firms are characterised as having severe agency problems.     

Effects of audit partners on clients’ business risk disclosure

We empirically investigate audit engagement partners’ involvement in business risk disclosure. Specifically, we examine whether the quality of business risk disclosure is influenced by engagement partner tenure and knowledge. We also examine whether the effects of partner tenure and knowledge are similar for Big 4 audit firms and non-Big 4 firms. Since fiscal year 2003, listed companies in Japan have been required to disclose business risk information. Although the business risk information is not audited, auditors concerned about their audit quality may seek to influence clients’ business risk disclosure practices. Giving advice to management on the narrative business risk disclosure can contribute to improving the perceived value of the auditor’s services which can be a competitive advantage. Using a sample of Japanese listed companies from 2003 to 2010, we find that if the engagement partners’ tenure is shorter, a company discloses more business risk information and the disclosure is more detailed. Furthermore, companies with audit partners who have a larger number of client engagements disclose larger amounts of business risk information in more detail. However, the engagement partner effects are mitigated if they belong to a Big 4 firm.     

Comparative analysis of environmental,social, and governance disclosures

We examine the level of environmental, social, and governance (ESG) sustainability disclosure by firms between two regimes where disclosure is mandatory versus voluntary. We use the regulatory environment between the United States (US) and European Union (EU) to compare ESG disclosures. Firms in the US are currently under a voluntary disclosure regime. In contrast, EU members are under a mandatory disclosure regulatory regime that began in 2017. We find that EU firms outperform US firms under voluntary disclosure requirements (2007–2016), and the ESG disclosure of EU firms further improves relative to US firms after the implementation of the mandatory disclosure in Europe in 2017. Our results suggest that the 2017 adoption of disclosure guidelines in the EU is associated with improvements in EU firms' ESG disclosure. Our results regarding the value-relevance of ESG disclosure support a move toward mandatory ESG disclosures. Results support current initiatives that have been taken by global regulators and stock exchanges in recommending and requiring globally listed companies to disclose their ESG sustainability information to portray accurate and comprehensive corporate reporting. The results further our understanding of how firms from different institutional environment settings may have disclosed their ESG practices, thus providing opportunities for future research.     

The Impact of Audit Committee Characteristics on CSR Disclosure: An Analysis of Australian Firms

This study examines the influence of audit committee (AC) characteristics on voluntary corporate social responsibility (CSR) disclosure in the corporate annual reports of Australian listed firms. It develops hypotheses about the relationship between voluntary CSR disclosure and AC characteristics such as size, frequency of meetings, independence, independent chair, financial expertise and gender diversity. Using multiple regression analysis on data collected from the corporate annual reports of 300 listed firms, the study finds that AC characteristics such as size, frequency of meetings, committee independence and gender diversity have a significant positive influence on the level of CSR disclosure. However, there is no evidence that AC characteristics such as independent chair and members’ financial expertise affect CSR disclosure in Australian firms. Based on an additional analysis, the study also sheds some light on the effect of AC characteristics on environmental disclosure. The findings of this study may be of particular interest to regulators, shareholders, investment analysts and managers in assessing CSR disclosure in annual reports, and in strengthening the monitoring and oversight role of ACs.     

企业社会责任:“真心”抑或“幌子”?——基于高管内幕交易视角的研究

企业承担社会责任究竟是“真心”还是“幌子”?与现有研究聚焦于考察社会责任对企业行为的影响不同,本文基于高管个体行为视角,实证检验企业社会责任对高管个体证券交易行为的影响。基于2008～2014年中国沪深A股上市公司高管10338个内幕交易样本的实证结果显示:(1)企业承担社会责任不仅能抑制高管内幕交易的规模,更能显著降低高管内幕交易获利性,这表明作为社会责任的谋划者,企业高管并未以社会责任为“幌子”牟取个人证券交易的私利,在一定程度上提供了企业“真心”承担社会责任的证据;(2)进一步从“信息模型”和“声誉模型”双重视角探究发现,在企业信息不透明和高管个人声誉较差的情况下,企业社会责任对高管内幕交易获利性的抑制作用更为显著;并且相较于高管个人声誉较差的情况,企业社会责任在信息不透明的情况下对高管内幕交易获利性的抑制作用更强。总之,本研究从高管个体行为视角提供了企业社会责任具有积极治理作用的证据,不仅丰富了企业承担社会责任经济后果的研究,同时,对利益相关者也具有实践指导意义。     

Voluntary Disclosure and Information Asymmetry: Evidence from the 2005 Securities Offering Reform

In 2005, the Securities and Exchange Commission enacted the Securities Offering Reform (Reform), which relaxes “gun‐jumping” restrictions, thereby allowing firms to more freely disclose information before equity offerings. We examine the effect of the Reform on voluntary disclosure behavior before equity offerings and the associated economic consequences. We find that firms provide significantly more preoffering disclosures after the Reform. Further, we find that these preoffering disclosures are associated with a decrease in information asymmetry and a reduction in the cost of raising equity capital. Our findings not only inform the debate on the market effect of the Reform, but also speak to the literature on the relation between voluntary disclosure and information asymmetry by examining the effect of quasi‐exogenous changes in voluntary disclosure on information asymmetry, and thus a firm's cost of capital.     

企业社会责任:“真心”抑或“幌子”?——基于高管内幕交易视角的研究

企业承担社会责任究竟是“真心”还是“幌子”?与现有研究聚焦于考察社会责任对企业行为的影响不同,本文基于高管个体行为视角,实证检验企业社会责任对高管个体证券交易行为的影响。基于2008～2014年中国沪深A股上市公司高管10338个内幕交易样本的实证结果显示:(1)企业承担社会责任不仅能抑制高管内幕交易的规模,更能显著降低高管内幕交易获利性,这表明作为社会责任的谋划者,企业高管并未以社会责任为“幌子”牟取个人证券交易的私利,在一定程度上提供了企业“真心”承担社会责任的证据;(2)进一步从“信息模型”和“声誉模型”双重视角探究发现,在企业信息不透明和高管个人声誉较差的情况下,企业社会责任对高管内幕交易获利性的抑制作用更为显著;并且相较于高管个人声誉较差的情况,企业社会责任在信息不透明的情况下对高管内幕交易获利性的抑制作用更强。总之,本研究从高管个体行为视角提供了企业社会责任具有积极治理作用的证据,不仅丰富了企业承担社会责任经济后果的研究,同时,对利益相关者也具有实践指导意义。     

Do Economic Incentives of Controlling Shareholders Influence Corporate Social Responsibility Disclosure? A Natural Experiment

We evaluate whether voluntary corporate social responsibility (CSR) disclosure is influenced by the economic incentives of controlling shareholders. To examine this research question, we apply the natural experiment setting based on the Split Share Structure Reform in China. Following this Reform, Chinese state shareholders are allowed to trade their shares in the stock market, which increases their incentives to maximize the market value of the firms that they control. We present empirical evidence of increased CSR disclosure among listed state-owned enterprises after this Reform. This evidence suggests that the economic incentives of key stakeholders are associated with voluntary CSR disclosures.     

Do Financial Markets Care about Corporate Social Responsibility Disclosure? Further Evidence from China

Corporations increasingly define their corporate social responsibility (CSR) activities as a part of their business. However, is this trend beneficial to investors? Based on an event study methodology and a sample of Chinese listed companies, we extend the literature on voluntary disclosure by exploring the role of CSR disclosure in reducing stock market information asymmetry, as proxied by share price volatility and liquidity. Our results show that the share price volatility after CSR disclosure is lower than before CSR disclosure; however, the trend is that it decreases first and then increases for three months following disclosure. Stock liquidity also significantly improves after CSR disclosure; however, it increases first and then decreases. Additionally, by dividing CSR disclosure into economic (hard) disclosure and generic (soft) disclosure, we find that the reduction in information asymmetry is higher for hard disclosure than soft disclosure, suggesting that although CSR disclosure does indeed have an impact on investors’ behaviour in China, an economic‐based disclosure contributes more substantially. Finally, to better understand the characteristics of the Chinese financial market, we also explore the role of marketisation with results that show that the effect in reducing information asymmetry is greater for companies located in a region with a higher degree of marketisation.     

Less timely earnings announcements and voluntary disclosure

The release of earnings information has become less timely in recent years partly because firms increasingly disclose earnings concurrently with their periodic reports (e.g., 10-Ks, 10-Qs). We examine whether firms use voluntary disclosure to mitigate the negative economic consequences of less timely earnings announcements (EAs). We find that firms with less timely EAs are more likely to provide voluntary 8-K filings over the period leading to the EA. We also find that investors’ demand for timely information, the nature of earnings news and litigation risk affect the extent to which firms provide voluntary disclosure to compensate for less timely EAs. The negative effect of less timely EAs on information asymmetry is attenuated when firms provide voluntary 8-K filings prior to EAs. Overall, our findings suggest that firms voluntarily communicate with investors using voluntary disclosure when their EAs are less timely.     

中期财务报告自愿审计的动机和市场反应分析——基于中国上市公司的经验数据

作为外部治理机制的审计是公司信息披露质量的重要保证,目前法规对上市公司中期财务报告的审计并无强制性法规要求,许多上市公司选择中期财务报表自愿审计,其行为是一种主动传递信息的过程。本文通过对我国上市公司2007至2010年证券市场自愿中报审计的经验数据分析,对公司自愿中报审计的动机和市场反应进行了实证研究。研究发现:公司中期财务报表自愿审计与公司的成长性和公司规模显著相关,且公司的财务状况和股权性质对公司的自愿审计有一定影响;同时,市场对上市公司中期财务报告自愿审计行为有一定的正面反应,但这种反应效力不足,且持续力较低。     

Going green: Market reaction to CSRwire news releases

Voluntary disclosure theory predicts that an optimal disclosure decision should produce an overall net benefit for shareholders, and that such net benefit should decrease in public information availability. This study supports the predictions of voluntary disclosure theory in the context of climate change. Using voluntary disclosures made through the CSRwire news service, we find that managers’ disclosure decisions involving greenhouse gas emissions produce positive returns to shareholders. This response varies negatively with company size and public information availability. For small companies in a limited public information environment, we find that mean market-adjusted share price increases significantly by 2.32% over days −2 to 2 around the CSR newswire release date. Our sample of disclosing companies received an aggregate market value boost from their CSR news releases of approximately ten billion dollars, independent of differences in public information availability.     

Capital market liberalisation and voluntary corporate social responsibility disclosure: Evidence from a quasi-natural experiment in China

This paper investigates the impact of the Shanghai–Hong Kong Stock Connect (SHSC) scheme on voluntary corporate social responsibility (CSR) disclosure in China. Using a difference-in-differences (DiD) design, we find that companies that participate in the SHSC scheme are more inclined to voluntarily issue CSR reports. This effect is more pronounced for companies that have limited access to international markets and those with weak corporate governance. Additional analyses show that SHSC-connected firms also produce higher quality CSR reports and achieve a better CSR performance. Our findings imply that capital market liberalisation promotes voluntary corporate disclosure for investors.     

Adjustment costs of institutional tax changes from the audit pricing perspective: Empirical evidence from the VAT reform

Institutional changes inevitably impose adjustment costs on firms while also generating benefits. However, empirical evidence regarding the adjustment costs of institutional changes is limited, with much of the focus centered on benefits. Using data on China’s A-share listed companies from 2010 to 2018 and the nation’s staggered adoption of the “business tax to value-added tax reform” (hereafter, “VAT reform”) as a natural experiment, we examine the impact of this reform on a particular corporate cost: audit fees. We find audit fees to be 8.11% higher for VAT reform firms than for non-VAT reform firms. This difference does not exist before or after the reform year. That is, it is only observed in the year of VAT reform implementation. This indicates the existence of an adjustment cost specifically related to the VAT reform. Furthermore, we observe larger fee increases among firms audited by Big 4 international audit firms, firms that require more audit work, firms that are more complex, and firms with weak internal controls. From the audit pricing perspective, we provide evidence of the economic consequences of tax reform. The corporate adjustment costs that arise from institutional changes deserve more attention from decision-makers.     

Corporate Social Responsibility,Institutional Environments,and Tax Avoidance: Evidence from a Subnational Comparison in China

We examine the association between mandatory corporate social responsibility (CSR) disclosure and economic contribution (tax payments) in China, where we expect this association to be affected by a region's institutional attributes. Exploiting a dataset that shows cross-regional variations in institutions, we find that in regions with lower institutional quality, firms claiming to be socially responsible actually avoid taxes, whereas CSR disclosure in other regions is more aligned with the social responsibility aspect of tax compliance. Our study contributes to the literature by demonstrating that in the absence of proper institutions, CSR disclosure is likely to remain a form of window dressing.     

Book Reviews

This paper examines factors affecting the owner-manager's voluntary decision to hire an auditor in small firms. Using a random sample of 412 small private companies in Finland responding to an Internet survey, we first probe the institutional boundaries of a prior UK study [Collis, J., Jarvis, R., and Skerratt, L., 2004. The demand for the audit in small companies in the UK. Accounting and business research, 34 (2), 87–100] and conclude that its main findings can be generalised to a different regulatory setting (Finland) typical of many Continental European countries. Second, we broaden the prior research by testing new hypotheses regarding the drivers of an audit among small companies. We hypothesise and find evidence that outsourcing of critical accounting functions creates information asymmetry between the owner-manager and the external accountant, which may arouse the need for monitoring the external accountant through a voluntary audit. In addition, we find, as hypothesised, that tax advisory services provided by the external accountant reduce the likelihood of a voluntary audit. Moreover, we hypothesise that receiving a qualified opinion from the auditor reduces the likelihood of hiring an auditor voluntarily, whereas firms experiencing financial distress would be more willing to have their financial statements audited. We find evidence consistent with these hypotheses.     

公司特征与公司社会责任信息披露——来自我国上市公司的经验证据

本文在自愿性信息披露的研究框架下,结合公司社会责任理论,对我国上市公司的公司特征与公司社会责任信息披露之间关系进行了实证分析。文章选取了1999年到2004年在上海和深圳证券交易所上市交易的石化塑胶行业的A股公司作为研究样本,通过对年报进行内容分析,构建了公司社会责任信息披露指数。实证检验发现:(1)规模越大、盈利能力越好的公司越倾向于披露公司社会责任信息;(2)公司财务杠杆和再融资需求不影响公司社会责任信息披露;(3)包括上市地点和披露期间在内的披露环境对公司社会责任信息披露有显著影响。文章还对公司社会责任信息的提供者、使用者和监管者提出了建议。
