上市公司股权结构与股利政策相关性实证分析——西北五省区的数据

本文以2002年~2004年西北五省区有股利分配的上市公司作为样本,采用多元回归分析方法,验证股权结构自变量与股利之间的线性关系,用非线性回归方法检验未通过线性关系检验的自变量与股利之间的关系。结果发现,西北五省区股利偏低,股东对现金股利有不同偏好。     

上海A股市场股价波动相互影响能力实证研究

股票市场中股票价格的波动是相互影响的,但不同的股票其价格波动时对其他股票价格行为的影响能力是不同的。本文通过对我国上海A股市场的实证分析表明,有少数股票其价格波动时对其他股票价格行为有很强的影响能力,而大多数股票的这种影响能力很小。此外,单个股票价格波动时引起其他股票价格涨、跌的能力一般都有显著差异。     

论煤炭企业物流管理体系建设

经济结构转轨时期,物流管理在煤炭企业的运营中起着承前启后的作用。它必然是煤炭企业经济外向型转化的一个标志。但是不容怀疑的是:注入了新元素的现代化的煤炭企业物流管理,需要一个科学的体系来维护,而这个体系本身就是一个新的利润源。在避免煤炭的生产、供应、转换、存储、运输、仓储等条件的制约后,如何转化成一个快速的,稳定的资源体系,使其能够形成稳定的利润增长和煤炭运销工作,对外供应的一个新局面,也就成了新时期煤炭物流管理的工作重点,恰恰也正是我们需要研究的重点。     

The e-integration dilemma: The linkages between Internet technology application, trading partner relationships and structural change

The evidence from an empirical study involving 281 Australian organizations suggests that the availability, open nature, and (comparative) ease of implementation of Internet technologies for integration with trading partners, whilst on the one hand providing the means by which organizations can integrate processes and systems in a cost effective way, can amplify the need for both structural change and closer collaboration with trading partners. The relationships proposed and tested in the model are justified and explained based on a number of theoretical perspectives. These include Transaction Cost Economics, Socio-technical Systems, Resource Dependency, Knowledge Based View, Stakeholder Theory and Organizational Learning. The implications of the findings for Transaction Cost Theory are noteworthy firstly because they support the appropriateness of the inter-organizational governance structure in the context of this study, and secondly because although application of these technologies may reduce information search and related costs, whether this necessarily leads to reduced coordination costs is problematic. The potential benefits from improved coordination may be constrained by the perceived costs, and risks, of transition to new structural forms. The implication for practice is that increased use of Internet technologies creates substantial pressure to invest in organizational change. The attractiveness of investing in technologies that place managers in a position where they need to promote organizational change in order to extract adequate returns creates a significant dilemma. On the one hand Internet technologies enable extensive sharing and integration of data among trading partners, but at the same time they create conditions requiring managers to embrace fundamental organizational change in order to leverage the potential of such integration.     

A network experiment in continuous time: The influence of link costs

In recent work on non-cooperative network formation star-shaped networks play an important role. In a particular theoretical model of Bala and Goyal (2000) center-sponsored stars are the only strict Nash networks. In testing this theoretical model, Falk and Kosfeld (2003) do not find experimental evidence that players select the center-sponsored star. Based on a slight modification of Bala and Goyal’s model, we design a network formation experiment in which, depending on link costs, periphery-sponsored stars and the empty network are the only strict Nash networks. We observe that almost all groups not only reach a strict Nash network once but also switch the center player in periphery-sponsored stars several times. The main innovation in our experiment is to use a continuous time framework which we believe to be a more realistic setting to study behavior in network formation situations and which makes coordination on stars much easier than simultaneous strategy adaptation in discrete time.

会计信息与公司治理结构分析

公司治理结构与会计信息都产生于委托代理理论、契约理论和产权理论的需要,理论基础的交叉重叠使会计信息与公司治理结构具有内在的逻辑性。会计信息质量决定公司治理效率,目前由于会计信息的有效需求不足和供给质量不高导致信息供需不均衡,从而使会计信息与公司治理陷入恶性循环,本文通过剖析信息供需机制不均衡的原因,提出完善的对策和建议。

社会资本外部性的经济分析——以信任关系为例

以往理论研究与经验研究均指出社会资本具有正面的效应,但对这种效应是怎样取得的并无共识.我们尝试建立一个不完全信息动态博弈模型,说明社会资本-信任如何产生正的外部性,亦即产生超出个体理性计算之外的利益.我们的分析得出这样的结论,在一个多人互动的环境中,能否达到彼此合作或彼此信任,虽然会受到欺骗者所遭到的惩罚与欺骗利益多少的影响,但主要受到所处环境中具有社会资本者人数比例的影响.因此,可以说社会资本具有正的网络外部性,信任者人数越多,信任者所享受到的利益越大.     

动态效率、生产性公共支出与结构效应

利用1979-2008年三次产业的数据和误差修正模型,本文估算了我国政府生产性公共支出与经济动态无效的长期关系,考察了政府生产性公共支出对三次产业的生产要素积累所产生的影响。研究发现:在结构效应为正的条件下,当期公共支出的增加能够影响资本和劳动在三次产业之间,以及三次产业内部不同行业之间的要素积累方式,起到改善经济结构、优化资源配置的作用;我国经济的投资拉动型增长方式及与之相伴随的公共品供给机制,通过"租金"创造机制诱导特定产业的发展,从而能够提升产业结构,促进资源和生产要素的优化配置,符合赶超型经济的目标要求。     

基于网络环境的会计教学问题探究

随着互连网与通讯技术、计算机软硬件设备与科技的快速进步,信息技术将是会计教育与教学中的必要元素,信息技术与会计学科领域整合将是未来会计教育的主流。新的教育环境要求会计教育必须转变教育理念,改变传统的教学模式、更新教学内容、探究新的教学方法。本文就网络环境下的会计教育理念、教学模式、教学内容、教学方法等进行了研究。
