An econometric model based on a natural experiment and the difference-in-differences method is introduced to empirically investigate the impact of split share structure reform on capital structures. A total of 1026 listed companies in Chinese A-share during 2001–2011 are used as the sample for the research and interest-bearing debt ratios (BDRs) are taken as a representative indicator for capital structures. The theoretical and empirical analysis indicates that both market expansion effect and corporate governance effect caused by the split share structure reform are associated with an increase in BDR. As far as the timeliness is concerned, the effects of split share structure reform on capital structures will last 3–4 years.  相似文献

通过文献调查并结合案例的描述性分析,提出数字技术时代价值网络中不同行为主体之间的赋能内涵、关键维度以及基于赋能跨层次效应的价值共创行为分析框架。将"赋能氛围""主体赋能"分别作为价值网络中赋能的宏观维度和微观维度进行概念化。界定了两个维度的关键组成要素,分别包括信息共享、开放性结构、协同规则以及主体关系、资源整合和影响。构建了赋能的跨层次效应模型,分析了赋能的宏观-微观跨层次效应及其对价值网络生态和主体价值创造的影响。  相似文献

This research tests the mediational roles of hedonic and utilitarian values consumers receive from using mobile data services (MDS) on the relationship between mobile commerce experience and mobile provider brand equity. A theoretical model was developed based on a review of the existing literature, and a survey was developed to test the model using a sample of 371 students in major universities in Jordan. The structural findings showed that MDS experience positively influence MDS provider image, which positively influenced both utilitarian and hedonic values, the effect being stronger for the utilitarian value. Moreover, both types of perceived values from using the MDS fully mediate the effect of MDS provider image on mobile equity.  相似文献

China's new Corporate Income Tax Law was passed in March 2007 and took effect on 1 January 2008. We take advantage of this tax law change and use a difference‐in‐differences approach to empirically estimate the impact of taxation on asset structure. Employing the Chinese Industrial Enterprises Database from 2002 to 2008 to implement the analysis, we find evidence suggesting the presence of tax bias against investments in fixed assets. We address two potential concerns about our analysis and argue that our conclusion is not China‐specific; it is a general lesson for modern finance theory that is portable to developed countries.  相似文献

When employees are empowered to continuously record their employment-related frustrations—doing so on accessible, visually prominent media—process improvement becomes upgraded to operate in a truly continuous mode. Frustrations are a superior target of process improvement in that they get at deep-seated concerns of people who have first-order process awareness and are most directly impacted by process failings. Recording frustrations not only provides a sound basis for pressing on to solutions, but it is also cathartic. The act of recording frustrations prominently on company-sanctioned media provides a positive outlet for the frustrations themselves.  相似文献

The objective of this study was to explore the relationship between promoter ownership and capital structure of firms’ using a sample of Indian publicly listed firms for the period from 2006 to 2013. We find that the relationship between promoter ownership and leverage is inversely U-shaped in group-affiliated firms, whereas in stand-alone firms there is a U-shaped relationship. We argue that a substantial presence of family owners and the selection of managers from within the family play some role for such relationship in group-affiliated firms. On the other hand, the argument for observed relationship in stand-alone firms follows from alignment hypothesis, entrenchment hypothesis, managerial risk aversion hypothesis, and active monitoring hypothesis.  相似文献

This paper investigates the impact of rating agencies in a market with asymmetric information. In particular, the role of credit rating agencies as an intermediary between investors and bond issuers is discussed. We model this setting in a dynamic framework in which both rating agencies and bond issuers are of heterogeneous quality. Rating agencies can apply costly research technology to reveal the fundamental nature of bond issuers and engage in rating smoothing. We show that rating smoothing can compensate for low research quality, even though it is accompanied by a quality deterioration in the rating market and market clustering. Moreover, low-quality bond issuers have a general tendency to match with low-quality rating agencies. If investors place a strong emphasis on the reputation of rating agencies, rating markets also tend to be strongly clustered.  相似文献
