我国上市公司过度投资行为的识别 总被引:4,自引:0,他引:4
郑玲 《中南财经政法大学学报》2008,(4)
由于股东和经理之间存在信息不对称而产生的代理成本问题,使得经理有过度投资的倾向,但是原有过度投资的检验方法并未能准确地界定过度投资行为。本文在综合考虑项目投资的期限、投资的行业差异和投资收益情况因素后确定了过度投资行为的判断标准,在此基础上进行过度投资的识别可以更好地发现存在过度投资的企业,并为进一步研究过度投资的治理提供准确的数据支持。过度投资上市公司在负债比例、投资年度的收益以及是否处于战略扩张阶段等方面和其他上市公司存在显著差异。 相似文献

Revenge Exacerbates the Effects of Interpersonal Problems on Mentors’ Emotional Exhaustion and Work‐Family Conflict: A Self‐Defeating Perspective 下载免费PDF全文
Drawing on conservation of resources theory, this study examined the link between negative mentoring experiences (i.e., interpersonal problems) perceived by mentors and their work‐family conflict (WFC) by focusing on the mediating role of emotional exhaustion and the moderating role of revenge. The results of a field survey of 187 mentors in China supported all of our hypotheses, indicating that interpersonal problems perceived by mentors were positively related to their WFC. This relationship was also found to be mediated by the mentors’ emotional exhaustion. In addition, revenge against protégés was found to moderate the main effect of interpersonal problems on emotional exhaustion and the indirect effect of interpersonal problems on WFC. Specifically, revenge exacerbated the positive relationship between interpersonal problems and emotional exhaustion. Further, emotional exhaustion mediated the indirect effect of interpersonal problems on WFC when the level of revenge was high, but not when it was low. The findings of this study provide insightful theoretical contributions and managerial implications that indicate new directions for research related to mentoring and work‐family relationships. © 2016 Wiley Periodicals, Inc. 相似文献

本文结合博弈论和计量经济学的Eview5工具对我国城市污水处理过程中各投资主体和资金来源进行实证研究,结果表明:民间资本在城市污水处理投融资过程中的地位越来越重要,所起作用已经超过政府资本;政府资本效用的下降,说明了政府资本使用效率低的问题,但政府在整个过程中监督管理的角色不会变。接下来我国城市污水处理的投融资模式将以市场化为主,政府资本为辅这一基本思路进行选择。 相似文献

In this study, we revisit the relationship between analyst firm coverage and forecast accuracy. In contrast to the proposed negative association in Clement (1999) owing to the portfolio complexity effect, we hypothesize an ‘economy‐of‐scale effect’ that is likely to dominate when analysts rely mostly on public information. In support of the latter effect, we find a positive association between firm coverage and forecast accuracy after the enactment of Regulation Fair Disclosure (Reg FD), which substantially reduces the flow of material private information to analysts. Such a result survives a battery of robustness analyses. We further show that, in the post‐Reg FD period, covering more firms increases an analyst's probability of being selected as a star analyst in the subsequent year. Overall, our findings highlight the importance of the information environment in shaping the economic link between an analyst's firm coverage and forecast accuracy. 相似文献

This paper reviews accounting and accountability research in Fiji. The review is based on 47 papers published since 1978 in accounting refereed journals, professional journals, edited book chapters and theses and other refereed journals outside accounting. In addition to categorisation of the reviewed papers according to accounting topics, theories and methods of data collection, some themes to which the papers could be related are discussed. Financial reporting/accountability research is the most popular research in Fiji followed by new public management research, with sustainability accounting research the third most popular. The paper's findings suggest some directions for future accounting research in Fiji and where the data can possibly be sourced for such research. We conclude that more research is needed in the Fijian context that focuses on accounting and the state, performance auditing, indigenous accounting, SMEs and accountability. 相似文献
