公司盈余质量:董事会微观治理绩效之考察——来自我国独立董事制度强制性变迁的经验证据 总被引:3,自引:0,他引:3
本文选用我国上市公司董事会结构变迁背景下的经验数据,系统地考察了董事会特征对公司盈余信息披露质量的治理效应问题.研究结果表明,董事会的独立性、专业性特征是影响我国上市公司财务呈报质量的重要因素,即:公司拥有更高比例的独立董事、拥有财务独立董事、或者设立审计委员会,均能更好地抑制公司的盈余管理行为;但作为表征董事会行为特征的变量,如董事会持股水平、董事会年度会议频率和兼任控股股东职务等,却与公司盈余质量之间没有显著关系;而且,在认同审计委员会与独立董事制度能够发挥财务报告监督作用的同时,亦要避免其形式上的装饰现象。 相似文献

为了探讨独立董事在我国上市公司中的作用和运作机制,本文构建了一个博弈模型,来反应在大股东与市场上的出资人之间的博弈中,独立董事所发挥的间接的信号作用.模型中,由于出资人不能区分公司大股东是否有侵吞中小股东资产的意图,在没有任何信号(包括独立董事制度)的情况下,无侵吞意图的公司的资产会被低估,而有侵吞意图的公司则会被高估.无侵吞意图的大股东有可能通过聘请较多的独立董事来将自己和有侵吞意图的公司区分开来,使得高的独立董事比例成为一个正的信号,向出资人显示自己没有侵吞中小股东资产的意图. 相似文献

针对多指标描述的一类社会事物群体,提出了一种基于客体优势识别视角的自主式竞优评析方法。该方法以最大程度的尊重事物客体的内质差异为出发点,将竞优评析过程分为个体优势识别、竞优模式识别和模式话语权重确定三个阶段。首先在不违背群体公共价值观念的前提下,从最有利于事物个体的角度识别其优势特征;其次利用聚类分析的方法,从优势特征集中识别群体竞优行为的模式特征;然后以各竞优模式包含的个体数量和评价信息的差异程度为基准确定各模式的话语权重,并得到最终的评价结果。最后以一个算例证明了方法的可行性和有效性。 相似文献

研究聚焦董事会内部沟通网络,基于独立董事信息共享机制探讨对高管薪酬的监督效果。研究发现,独立董事相互之间通过共享信息来增强对高管自利行为的抑制能力,有效降低了高管薪酬。同时,管理者权力对独立董事信息共享机制的监督效力起到调节作用,具体表现为随着管理者权力的增强,独立董事信息共享对于高管薪酬的约束作用被弱化,这一结果说明独立董事信息共享机制的监督有效性受到管理者权力的限制。研究构建了独立董事信息共享指标,并基于董事会监督博弈过程分析信息共享对高管自利行为的约束过程,最后运用A股上市公司数据加以验证。研究拓展了对独立董事监督机制的认识,为打开董事会“黑箱”、提升董事会绩效提供新视角,促进公司治理机制由静态结构研究向动态过程研究转化。 相似文献

审计委员会的设立与公司治理——基于审计收费的实证研究 总被引:3,自引:0,他引:3
采用非参数检验方法和回归分析方法,本文从审计费用率视角研究了审计委员会的设立对上市公司治理的影响。本文发现,在设立审计委员会的样本和未设立审计委员会的样本之间,董事会的规模和独立性、独立董事规模和报酬存在显著差异,且这些变量及独立董事规模、审计任期与审计费用率的相关性不同。结果表明,审计委员会在加强独立董事责任和董事会、外部审计师独立性的同时,也改善了公司内部控制系统,但整体上并没有改变审计师的任期。 相似文献

This work studies voting according to the veto model used by a board of directors to choose between several ways of development of a corporation. Several rules for choosing are considered, including the possibility of a certain player determining the order of the other players’ moves. The specified task is to find the most advantageous preferences of the voters from the viewpoint of the player who makes his choice first. Of special interest is a situation in which one of the players predominates and can determine the order of the other voters’ moves. The problem is solved for three players both in a case of strict preferences and in a case where the voters decide between several equally preferable ways of developing the corporation. 相似文献

In this article, we focus on the conflict among the manager, the controller and the board of directors of a company. We model the problem as a three-player polymatrix game. Under a set of assumptions, we identify five potential Nash equilibria. We prove that the Nash equilibrium is unique, despite its changing structure. Next, we analyze the influence of the manager’s and controller’s bonuses and penalties on the Nash equilibria. Finally, we explain how the manager and the controller may decrease or maintain their performance, when their bonuses or penalties increase. 相似文献

This study seeks to determine the effectiveness of corporate governance by analyzing the impact of board structure on firm
technical efficiency. Resampling methods and bootstrapping techniques applied in Data Envelopment Analysis are used to evaluate
firm performance. Truncated regressions are estimated to determine the effect of five board characteristics—board size, board
independence, board reputation, board diversity and board activity—on efficiency. The result of this empirical study shows
that business technical efficiency increases with a heterogeneous board with a limited number of directorships per director
and with a limited activity specified in a reduced number of annual board meetings with a higher number of specialized committees. 相似文献

We formulate the static mechanical coupling of a geometrically exact Cosserat rod to a nonlinearly elastic continuum. In this setting, appropriate coupling conditions have to connect a one-dimensional model with director variables to a three-dimensional model without directors. Two alternative coupling conditions are proposed, which correspond to two different configuration trace spaces. For both, we show existence of solutions of the coupled problems, using the direct method of the calculus of variations. From the first-order optimality conditions, we also derive the corresponding conditions for the dual variables. These are then interpreted in mechanical terms. 相似文献
