建立独立董事制度规范公司法人治理结构

随着经济全球化步伐的日益加快,加快建立独立董事制度,规范中国公司法人治理结构毋庸置疑.通过借鉴英美法系国家建立独立董事制度与规范公司法人治理结构的经验,本文就加快建立独立董事制度,规范中国公司法人治理结构的重大意义及应解决的若干问题略作探讨.     

公司治理结构与独立董事制度

公司治理结构模式的选择决定了监督机制生存的土壤 ,在不同的公司治理结构下所选择的监督结构模式各有其优点和不足。在我国“双层制”的治理结构中引入独立董事制度会存在与既有监事会制度的矛盾 ,如何协调并且尽最大可能发挥二者的功效是文章关注的重点     

独立董事制度质疑与公司监控机制的完善

我国证券管理机构在上市公司中推行独立董事制度的意向 ,忽略了不同国家的法律文化、法律传统等方面的制度差异 ,也缺乏相应的配套制度。要从根本上改变我国上市公司监控失灵、法人治理水平落后的局面 ,必须优化监事会功能 ,进行监督制度的创新 ,实现监控模式由内部单边监控向内部和外部多边监控的转变。     

董事会结构对行为影响的实证分析

董事会结构是企业的微观制度,董事会行为包括了战略行为与控制行为。以2006—2008年中国上市公司为样本,实证分析董事会结构对董事会行为的影响。回归结果发现,董事会专业性、总经理/董事两职合一、激励性、国际化程度分别与董事会战略行为显著正相关;董事会独立性、专业性、激励性分别与董事会控制行为显著正相关。研究表明,董事会结构是董事会行为的前提和基础,董事会行为是董事会结构有效作用的外在表现形式。     

我国多层次资本条件下转板机制的构建

转板是指根据信息披露质量、财务规模、股份构成等情况,公司可以在不同证券市场或同一证券市场不同层次市场之间转换上市或挂牌进行股份交易或转让。转板机制是我国当前加紧构建的多层次资本市场的核心制度。一个真正的多层次资本市场,不同板块之间的直接转板机制应该是畅通的。我国《证券法》目前对于转板存在一定的法律障碍。鉴于实际操作中还不允许转板,不利于多层次资本市场的建设,也不利于交易(场)所之间的竞争,因此,建议在修改《证券法》时扫除转板的法律障碍,增加转板的有关规定。     

Why and when female directors are less engaged in their board duties: An interface perspective

Female representation on boards is perhaps one of the most studied topics in board-governance research. At the same time, much is unknown about female directors' task engagement within boards. Drawing from psychological theory on societal gender beliefs, our study tests whether the impact of director gender on supervisory task engagement hinges on status dynamics in two relational interfaces: the director–board interface and the director–CEO interface. According to this perspective, female directors show less task engagement because gender is a diffuse status cue that creates status differentiation within the director–board interface. Multi-source board survey data (n = 61 boards, n = 315 directors) confirms that, within the confines of the boardroom, female directors do, indeed, receive lower-status ratings than male directors. This effect is weaker when boards have a female chair. Furthermore, lower status explains perceived lower task engagement of female directors, but this link critically hinges on the CEO–director interface. The impact of status differences is more pronounced when directors intersect with a relatively dominant CEO. All in all, the results demonstrate that relational interfaces play a key role for female directors’ task engagement in their board duties.     

A heuristic approach for component scheduling on a high-speed PCB assembly machine

The collect-and-place machine is one of the most widely used placement machines for assembling electronic components on the printed circuit boards (PCBs). Nevertheless, the number of researches concerning the optimisation of the machine performance is very few. This motivates us to study the component scheduling problem for this type of machine with the objective of minimising the total assembly time. The component scheduling problem is an integration of the component sequencing problem, that is, the sequencing of component placements; and the feeder arrangement problem, that is, the assignment of component types to feeders. To solve the component scheduling problem efficiently, a hybrid genetic algorithm is developed in this paper. A numerical example is used to compare the performance of the algorithm with different component grouping approaches and different population sizes.     

中国创业板和主板市场之间的相关结构分析——基于Copula函数的实证研究

了解创业板与主板市场间的关系,对于理解两个市场的互动关系以及证券组合的设计和风险评估至关重要。文章利用创业板指数、沪深300指数数据,借助ARMA-GARCH-Normal-Copula和ARMA-GARCH-T-Copula模型分析了创业板和主板之间的相关结构。研究表明:创业板市场的波动要大于主板市场,创业板和主板存在一定的正相关关系,并且存在非对称的尾部结构;在尾部(上尾和下尾)上,创业板对主板的变化反应比主板对创业板的变化反应更强。
