ABSTRACT

This paper performs topic modeling using all publicly available CSR (Corporate Social Responsibility) reports for all constituent firms of the major stock market indices of 15 industrialized countries included in MSCI Europe for the sample period from 1999 to 2016. Our text mining results and LDA analyses indicate that ‘employees safety’, ‘employees training support’, ‘carbon emission’, ‘human right’, ‘efficient power’, and ‘healthcare medicines’ are the common topics reported by publicly listed companies in Europe and the UK. There is a clear sector bias with industrial firms emphasizing ‘employee safety’, Utilities concentrating on ‘efficient power’ while consumer discretionary and consumer staples highlighting ‘food waste’ and ‘food packaging.’ To produce these results, we used a battery of python code to organize the hundreds of reports downloaded from Bloomberg and the internet, the latest R-algorithm to estimate LDA (Latent Dirichlet Allocation) model and the LDAvis interactive tool to visualize and refine the LDA model.  相似文献

A plethora of governance measures has been developed to assess governance capacity in different countries. Choosing one indicator over another involves discretionary decision issues. This article presents a new unified measure of governance capacity for the administrative and political dimensions. The unified measure provides a more accurate understanding of governance than single indices.  相似文献

金融集团的公司治理:典型模式的案例分析   总被引:2,自引:1,他引:2  
于东智 《金融论坛》2005,10(1):3-10
本文对花旗集团、德意志银行集团以及三菱东京金融集团的公司治理实践进行了详细的比较分析。研究表明,三种金融集团治理模式之间存在着显著差异,但又不乏一些共性。比较分析后得到如下启示:国有商业银行应该进行股份制改造并成为上市公司;商业银行的公司治理应该以“长期股东价值最大化”为目标;要进一步明确以风险管理原则为基础构建商业银行治理结构的重要性;应该进一步强化监事会的功能,保证监事会的独立性,并使监事具备任职的积极资格;实现责任人的绩效与薪酬额度的有机结合是我们构建高效的激励机制的努力方向;要实现我国银行业的国际化、集团化与多元化。  相似文献

We investigate the impact of social media data in predicting the Tehran Stock Exchange variables for the first time. We consider the closing price and daily return of three different stocks for this investigation. We collected our social media data from Sahamyab.com/stocktwits for about 3 months. To extract information from online comments, we propose a hybrid sentiment analysis approach that combines lexicon‐based and learning‐based methods. Since lexicons that are available for the Persian language are not practical for sentiment analysis in the stock market domain, we built a particular sentiment lexicon for this domain. After designing and calculating daily sentiment indices using the sentiment of the comments, we examine their impact on the baseline models that only use historical market data and propose new predictor models using multi‐regression analysis. In addition to the sentiments, we also examine the comments volume and the users' reliabilities. We conclude that the predictability of various stocks in the Tehran Stock Exchange is different depending on their attributes. Moreover, we indicate that only comments volume could be useful for predicting the closing price, and both the volume and the sentiment of the comments could be useful for predicting the daily return. We demonstrate that users' trust coefficients have different behaviours toward the three stocks.  相似文献

This study investigates whether corporate governance affects the impact of the relationship between fundamental signals and stock returns using Taiwanese data. The study employs the endogenous switching model (ESM) of Hu and Schiantarelli (1998), which combines the response equation and governance index equation simultaneously. We divide the sample into strong and weak governance regimes. Our results suggest that stock returns respond differently in different governance regimes. The beneficial response is greater in the strong governance regime than in the weak one, suggesting that it is worth improving governance for firms.  相似文献

Advances in Deep Learning have drastically improved the abilities of Natural Language Processing (NLP) research, creating new state-of-the-art benchmarks. Two research streams at the forefront of NLP analysis are transformer architecture and multimodal analysis. This paper critically evaluates the extant literature applying sentiment analysis techniques to the financial domain. We classify the financial sentiment analysis literature according to the most used techniques in the area, with a focus on methods used to detect sentiment within corporate earnings conference calls, because of their dual modality (text-audio) nature. We find that the financial literature follows a similar path to NLP sentiment literature, in that more advanced techniques to define sentiment are being used as the field progresses. However, techniques used to determine financial sentiment currently fall behind state-of-the-art techniques used within NLP. Two future directions stem from this paper. Firstly, we propose that the adoption of transformer architecture to create robust representations of textual data could enhance sentiment analysis in academic finance. Secondly, the adoption of multimodal classifiers in finance represents a new, currently underexplored area of study that offers opportunities for finance research.  相似文献

证券信息网络披露使证券市场投资者能够便捷的获取全面丰富的证券信息,但浩如烟海的篇幅和晦涩难懂的专业词汇,常常使投资者特别是中小投资者陷入不知所措的境地。我国资本市场以中小投资者为主,为了切实保护其利益,有必要确立证券信息披露的简明性规则,即在信息披露中使用清晰、简单、易懂的语言,在能够使用普通语言的场合,避免使用专业的金融词汇,同时,信息披露文件的篇幅应当简短,避免冗长。信息披露简明性规则不会增加发行人的信息披露责任,不会影响信息披露的完整性,有助于保护中小投资者利益。  相似文献

There are two theories on the determinants of the control structure of the firm. The first theory postulates that the control structure is determined by company-specific characteristics. The second theory emphasises the importance of institutional characteristics in shaping this structure. In this paper, we test the validity of both theories in the context of a cross-listing, which causes a change to the company's legal environment. We find that the initial control structure, risk and size determine the control structure post cross-listing and that cross-listing on better quality markets facilitates the evolution of control towards more dispersed control. To conclude, company characteristics have a greater impact than country characteristics on the company's decision to cross-list and are also better at explaining the change in the control structure post cross-listing.  相似文献

Natural language processing (NLP) is a part of the artificial intelligence domain focused on communication between humans and computers. NLP attempts to address the inherent problem that while human communications are often ambiguous and imprecise, computers require unambiguous and precise messages to enable understanding. The accounting, auditing and finance domains frequently put forth textual documents intended to communicate a wide variety of messages, including, but not limited to, corporate financial performance, management's assessment of current and future firm performance, analysts’ assessments of firm performance, domain standards and regulations as well as evidence of compliance with relevant standards and regulations. NLP applications have been used to mine these documents to obtain insights, make inferences and to create additional methodologies and artefacts to advance knowledge in accounting, auditing and finance. This paper synthesizes the extant literature in NLP in accounting, auditing and finance to establish the state of current knowledge and to identify paths for future research.

我国上市公司债权人治理弱化及其对策   总被引:4,自引:0,他引:4  
我国公司治理准则的指导思想是利益相关者共同治理,它涉及股东、债权人、顾客、供应两等共同治理。但我国债权人作为公司外部治理的主要力量并没有发挥其应有的作用,特别是银行在公司治理中的作用非常有限。为此,重点研究我国上市公司债权人治理的现状,以及治理弱化的原因,并对完善上市公司债权人治理提出若干建议。  相似文献

从公司治理角度分析\"股利税\"的改革方向   总被引:1,自引:0,他引:1  
股利在公司治理中具有重要作用,股利税的不同设计对企业公司治理有重要影响。为有效利用税法完善企业的公司治理,建议对个人的股利所得适用较低税率的\"双重征税\"形式,以减少企业派发股利的税收成本,缓减\"自由现金流\"代理问题,同时发挥债权人和机构投资者的治理优势;对于公司间股利所得,按持股比例规定适用税率,以减少集团企业控制权与现金权分离的程度,缓解控股股东与中小股东的代理问题。  相似文献

公司治理与会计稳健性——基于上市公司的实证研究   总被引:8,自引:0,他引:8  
会计稳健性是财务报告的一个重要特征和惯例,已成为会计盈余的重要质量特征之一。本文运用basu(1997)模型,将会计稳健性定义为会计报告对坏消息的确认比好消息更及时,探讨了有关公司治理的几个重要因素对会计稳健性的影响。研究发现:在影响会计稳健性的治理因素中,银行借款比例与会计稳健性正相关,国家股比例与会计稳健性负相关,在国家股比例低的分组,会计稳健性较高。发行有B股的企业,会计稳健性与只有A股的企业没有显著差异。研究表明,会计稳健性作为会计报告质量的一种量度,随着会计制度和准则的国际接轨与完善,证券市场监管的加强,取得了一定成效,但是会计准则和会计制度不能保证会计报告的质量,尚需改革国内相关的制度背景,如公司治理、法律实施环境等。  相似文献

上市公司债务融资与公司价值的实证研究   总被引:1,自引:0,他引:1  
本文利用中国所有A股上市公司1998~2005年的数据,改进了汪辉(2003)实证模型,来检验上市公司债务融资与公司价值的关系,发现上市公司债务融资净额占总资产的2.27%;资产负债率在30~60%之间的上市公司的负债融资,有利于增加公司的市场价值,资产负债率小或者大的公司这种效应不显著;同时债务融资对传递公司的业绩具有很强的信号作用,公司价值越高的公司,未来进行债务融资的可能性越大。  相似文献

我国券商治理风险及对策   总被引:1,自引:0,他引:1  
我国证券公司经营户中存在多种委托-代理关系。在现行的治理框架下,股东相容性风险、股东-经营层代理风险和客户-经营层代理风险均居高不下,使得治理风险成为我国券行业的最大风险。以国有产权为主导的产权结构和激励不相容的外部治理机制是滋生治理风险的源头,也是解决问题的切入点。  相似文献

我国上市商业银行公司治理绩效的实证研究   总被引:1,自引:0,他引:1  
巩师恩 《海南金融》2009,(12):72-75
商业银行公司治理结构是现代银行制度的核心,对于商业银行的发展具有决定意义的作用。我国上市商业银行是按照现代企业制度的要求建立起来的,在公司治理方面相对我国其他类型银行具有一定的借鉴意义,因此对我国上市商业银行进行研究具有一定的理论和应用价值。本文采用实证研究方法,通过对于商业银行年报中披露的有关公司治理数据的统计分析,考察了公司治理结构中股权结构、董事会特征、监事会特征、高级管理层激励特征等各类治理指标对于商业银行公司业绩的影响关系。  相似文献

上市公司治理领域长期以来依照强制性法律规范来运行,然而,上市公司治理的规范诉求的特性决定了单一的法律规范体系的局限性。以或遵守或解释规则为核心的倡导性公司治理规范迎合了上市公司治理的需求,并取得了显著的执行率。中国《上市公司治理准则》可进行适当的改革:从法律规范转变为倡导性规范;通过证监会信息披露法律规范的形式强化上市公司关于准则遵守或者解释的程序上的披露义务;利用现有的法律机制确保准则的有效执行,并鼓励股东发挥评判监督作用。  相似文献
