企业数字化转型、预判性信息披露与股价暴跌风险

在数字经济发展热潮下,资本市场对企业数字化转型的热情与憧憬是否酝酿了股价泡沫?年报中的数字化信息披露是否导致未来股价暴跌风险提高?基于2012—2019年A股上市公司的年报文本和财务数据,本文采用自然语言处理中的依存句法分析,创新性地将年报中的数字化相关信息划分为与宏观环境和未来展望相关的预判性内容,以及反映过去数字化行为的行动性内容。实证结果发现,上市公司披露的数字化相关信息将提高未来股价暴跌风险,并且该影响主要体现在预判性数字化信息披露上。进一步研究表明,普通投资者受从众心理影响,盲目追捧“数字化”相关概念,对预判性内容中的数字化信息过度反应、错误预期,是引发股价暴涨暴跌的主要原因。而这种不加甄别的高度关注显著降低了股价信息含量,加剧了股市同涨同跌,并且其引发的股票市值上涨也难以维持。本文的政策建议是,要加强投资者教育,防范市场过度反应,在经济数字化转型中维护金融市场稳定,更好地促进传统产业转型升级。     

环境信息披露对股价崩盘风险影响分析

伴随社会进步,人们的环保意识不断提高,环境信息逐渐成为投资者评判一家企业的重要参考。此背景下,环境信息披露的重要程度进一步上升。股价崩盘是一种股市极端现象,对行业、市场以及整体经济的发展有较大负面影响。相关研究证实,环境信息的披露可以影响股价崩盘风险。为进一步了解环境信息披露与股价崩盘之间的关系,文章在概括环境信息披露、股价崩盘的基础上,从环境信息披露的透明度、环境信息披露的内容以及相关监管入手,对环境信息披露对股价崩盘的影响进行分析并提出相应建议,旨在提高环境信息披露质量、抑制股价崩盘风险。     

浅谈创业板上市公司股价暴跌的原因及应对

创业板是指专为暂时无法在主板上市的中小企业和新兴公司提供融资途径和成长空间的证券交易市场,是对主板市场的重要补充,在资本市场有着重要的位置.现如今,创业板市场的发行价越定越高,但是由于公司本身原因、外部投资者环境或者宏观经济环境的影响,导致创业板市场的上市公司股价出现暴跌现象,本文从这三个方面对创业板市场上市公司股价暴跌现象的原因作简要的分析并提出一定的应对建议.

交易所问询函监管对公司避税的影响

本文以上市公司避税行为为切入点,探讨了证券交易所问询函监管制度的外部治理效应.研究发现:问询函监管能缓解收函公司的避税程度,问询函次数与公司避税程度显著负相关.当问询函属于财务报告问询函时,问询监管能显著缓解公司避税程度.进一步研究发现:问询函监管可以通过降低信息不对称来缓解企业的避税程度.     

上市公司信息透明度与股价同步性关系的研究述评

公司信息透明度是影响股价同步性的关键因素。二者之间的关系一直是学术界广泛关注的焦点,基于我国的金融发展背景,不同的学者通过不同的研究方法采用不同的数据得到的结论是不一致的。本文通过对该领域的研究文献进行梳理,归纳两者关系存在的原因及传导机制,并对如何提高上市公司股票价格信息含量提出政策建议。     

会计信息透明度与股价崩盘风险关系实证研究

基于信息不完全假说,以我国2007-2012年A股上市公司作为研究样本,实证检验了会计信息透明度对股价崩盘风险的影响。实证结果表明,会计信息透明度越低,未来股价崩盘风险越大;相反地,会计信息透明度越高,未来股价崩盘的可能性越小。提高会计信息透明度是降低股价崩盘风险的有效方法之一,良好的会计信息透明度可以有效地提高资本市场稀缺资源的配置效率,有助于保护投资者的投资利益。     

经营现金流透明度、市场关注度与股价崩盘风险

选取2008—2015年A股上市公司数据,实证分析经营现金流透明度与公司股价崩盘风险之间的关系,结果表明,相比于应计会计盈余,经营现金流具有更多的信息含量,对股价崩盘风险具有更强的解释力。进一步,考察市场关注度对经营现金流透明度与公司股价崩盘风险关系的调节效应,发现市场关注度对股价崩盘风险存在双重影响,主要表现为:一方面,市场关注度的提高增大了企业管理层的经营压力,使其更倾向于操纵现金流信息,进而导致现金流透明度降低,股价崩盘风险升高;另一方面,随着市场关注度的逐步提高,投资者消化、吸收与理解信息的能力也在不断提升,企业隐藏坏消息的能力受到限制,从而降低了经营现金流透明度对股价崩盘风险的影响,即表现为市场关注度越高,经营现金流透明度对股价崩盘风险的影响越弱。     

社会信任与股价崩盘风险

本文以我国2000-2014年沪深两市A股、非金融行业上市公司为样本,实证考察地区社会信任水平和股价崩盘风险的内在联系,以及正式制度如何影响这种内在联系.研究发现,上市公司所在地区社会信任水平越高,公司股价在未来崩盘的风险越小.这说明社会信任作为一种非正式制度,抑制了管理层隐藏坏消息的机会主义行为.进一步的研究发现,信任对股价崩盘风险的抑制作用仅在市场化程度较高和法律环境较好的地区存在.本研究不仅从学理上揭示了非正式制度、正式制度如何影响股价崩盘风险,而且为监管部门如何通过制度建设促进金融市场稳定提供了决策参考.     

企业内部监督与股价崩盘风险——基于代理成本和信息透明度的中介效应检验

文章以2007—2017年我国沪深A股上市公司为样本,探究了企业内部监督对股价崩盘风险的影响及其作用机制。研究结果显示,企业的内部监督程度越高,股价崩盘风险越低;企业的内部监督通过降低代理成本和提高信息透明度来降低股价崩盘风险,即代理成本和信息透明度是内部监督与股价崩盘风险之间的两个中介变量。进一步研究表明,企业内部监督对股价崩盘风险的降低作用在两职分离时更为显著。文章从企业内部监督的角度对股价崩盘风险进行研究,具有一定的理论价值和实践意义。     

资本市场开放与企业避税——基于沪港通和深港通交易制度的准自然实验

利用沪港通和深港通交易制度实施提供的准自然实验情境,以2008-2019年沪深两市A股上市公司为研究样本,考察资本市场开放对企业避税行为的影响.研究发现,资本市场开放对企业避税行为具有显著的抑制作用,即沪港通和深港通交易制度实施后,试点公司避税程度显著下降,该结果在经过一系列稳健性检验后仍然成立.作用机制分析结果表明,资本市场开放主要通过缓解融资约束、强化对管理层的监督以及提升信息透明度等途径抑制企业避税行为.异质性检验结果显示,资本市场开放对企业避税行为的抑制效应主要存在于代理问题和融资约束较为严重的企业中,即在机构投资者持股比例低和企业融资需求大的样本中,资本市场开放对企业避税行为的负向影响更强.     

Corporate Philanthropy and Stock Price Crash Risk: Evidence from China

How to mitigate stock price crash risk has become a focus in the theoretical and practical fields. Building on the work of Kim et al. (J Bank Finance, 43:1–13, 2014b), this paper investigates the relation between corporate philanthropy and crash risk under the unique Chinese institutional background. The results show that both state ownership and the 2005 split share reform attenuate the mitigating effect of corporate philanthropy on crash risk. Specifically, the negative relation between corporate philanthropy and crash risk is less pronounced for state-owned enterprises than for non-state-owned enterprises, and it is also less pronounced after firms accomplish the split share reform. Further, this effect is more pronounced for firms with greater financial risks and poorer performance. Our paper contributes to the growing literature on the determinants of stock price crash risk and the economic consequences of corporate philanthropy. It also offers useful guidance to firms that are seeking to reduce stock price crash risk in emerging markets.     

Large Shareholder Tunneling and Risk of Stock Price Crash： Evidence from China

Although several studies have examined the economic consequences of large shareholders＇ tunneling behavior, little attention has been paid to the negative effects of tunneling on firms＇ extreme events. In this article, we investigate how tunneling behavior affects firm-level stock price crashes. The findings indicate that the probability of stock price crashes is positively associated with the extent of tunneling behavior by large shareholders. The positive relationship is more pronounced after the split of share structure reform and is moderated by the firm＇s financial conditions. This study contributes to the emerging body of literature focusing on the economic consequences of tunneling and stock price crashes. The conclusions drawn from the study also provide a frame of reference for investor protection and investment portfolios based on large shareholders＇ tunneling behavior in China.

Family Firm Heterogeneity and Tax Aggressiveness: A Mixed Gamble Approach

Few studies try to understand how the unique preferences of family firms affect tax strategies, and how family firm heterogeneity drives variation in tax activities. Drawing on the mixed gamble approach, this study examines the tax aggressiveness of different types of family firms, considering how various sources of heterogeneity alter the perception of potential gains and losses to socioemotional and financial wealth. Based on a panel dataset of 242 private family firms for the period 2012–2014, this study shows that strong family-owned firms, family firms with a family CFO, family-founder firms, and family-named firms display lower levels of tax aggressiveness. These findings demonstrate that family firm heterogeneity is a crucial factor in the mixed gamble calculus of tax aggressiveness.     

Multinational Tax Avoidance: Virtue Ethics and the Role of Accountants

The techniques that some large multinational corporations use to reduce their tax liability have come under increasing public scrutiny in recent years, alongside governmental investigations and international commitments aimed at curbing opportunities for tax avoidance. Although discussion of tax avoidance activities, and their regulatory responses, is often conducted with reference to moral concepts (such as ‘fairness’), philosophical analysis of the ethics of multinational tax avoidance remains limited. In particular, the virtue ethics tradition that emphasises the agent (and his/her character) and the performance of specific roles has not been considered in detail. This paper examines how the contemporary virtue ethics of Alasdair MacIntyre can be applied to the issue of multinational tax avoidance, and considers the role that accountants play in these activities. It argues, firstly, that MacIntyre’s approach provides a more useful philosophical analysis of the issue (when compared to utilitarian and deontological approaches for example) and, secondly, that the main parties involved (MNC accountants and regulators) are likely to agree with the main tenets of this approach. The paper also contributes by reconceptualising, using MacIntyre’s scheme, the issue of tax avoidance in relation to Donald Cressey’s ‘fraud triangle’.     

税收征管、企业避税与企业全要素生产率——基于2002年企业所得税分享改革的自然实验

提高全要素生产率(TFP)是加快转变经济发展方式的关键。税收征管力度的高低会直接影响企业的生产经营决策,从而影响企业的发展转型。本文基于2002年实施的企业所得税分享改革自然实验,采用双倍差分法(DID)探讨了税收征管对企业TFP的影响。研究发现:(1)税收征管力度的下降会降低企业的TFP水平;(2)机制探讨过程发现,降低税收征管力度会增加企业避税行为,而避税增加会减少企业的研发投入,从而对企业TFP产生负面影响;(3)异质性分析发现,税收征管对非高新技术企业、非民族自治区域企业以及高避税程度企业的TFP的负面影响更大。本文的研究结论对于未来的税收体制改革具有重要启示。     

Fear Linkages Between the US and BRICS Stock Markets: A Frequency-Domain Causality

Abstract

We employ a spectral causality approach to uncover short-, medium-, and long-run causal relations between the US implied volatility index and the five individual implied volatility indexes of BRICS markets from 16^th March 2011 to 31^st January 2018. We show that the volatility causal relations differ between the short and long run in many cases. Although the results indicate the dominant role played by US uncertainty in shaping uncertainty in all BRICS markets, there is also evidence of a feedback effect from Brazil, Russia, and China to the US that differs across the spectrum. The implications for hedging and risk management practices are explored.
