浙江上市公司总体分析

浙江上市公司从数量上看，占了相当优势，排在全国的第4位，而且至今还未曾有退市的公司；从质量上看，也有较突出的特征，该板块的平均净资产值较高，按上市公司数量排的全国前10位中，排在第1位，达3．23元；从市盈率来看也说明了浙江板块的业绩较好，平均市盈率已达17．66倍。但也存在不足的一面，从对社会贡献的总量来看，还不是很突出，缺乏规模效益。

从美国公司财务假帐丑闻看公司治理和社会制约的完善

美国公司财务假帐频繁产生的原因有：公司管理制度和公司治理结构方面的变化对企业的约束力下降在社会中介机构的独立审计制度下部分中介机构与造假公司同流合污，法律制度的缺陷与不完备，以及政府对企业投资银行和征券行业的监管机制不健全等。有鉴于此，我国公司应建立、健全监音管理机制，并加强公司内部控制。

上市公司利润泡沫的剖析

利润是企业经营成果的集中体现,也是衡量企业经营管理业绩的主要指标之一。随着财务报告信息在市场经济中地位的不断提升,部分上市公司为了寻求对自己有利的财务成果,不惜一切手法操纵利润,甚至采用欺诈手段不合法地调整企业的利润,形成了泡沫利润,损害了投资者的利益,影响了我国证券市场的正常发展。本文针对目前上市公司财务报表的利润浮夸现象,就企业泡沫利润的形成原因、手段进行分析,并对如何识别泡沫利润的手段提出了初浅的看法,最后提出了相应的防范措施。

Sample Design and Allocation for Random Digit Dialling

Sample design and sample allocation methods are developed for random digit dialling in household telephone surveys. The proposed method is based on a two-way stratification of telephone numbers. A weighted probability proportional to size sample allocation technique is used, with auxiliary variables about the telephone coverage rates, within local telephone exchanges of each substrata. This makes the sampling design nearly “self-weighting” in residential numbers when the prior information is well assigned. A computer program generates random numbers for the local areas within the existing phone capacities. A simulation study has shown greater sample allocation gain by the weighted probabilities proportional to size measures over other sample allocation methods. The amount of dialling required to obtain the sample is less than for proportional allocation. A decrease is also observed on the gain in sample allocation for some methods through the increasing sample sizes.     

Robustness issues in multilevel regression analysis

A multilevel problem concerns a population with a hierarchical structure. A sample from such a population can be described as a multistage sample. First, a sample of higher level units is drawn (e.g. schools or organizations), and next a sample of the sub‐units from the available units (e.g. pupils in schools or employees in organizations). In such samples, the individual observations are in general not completely independent. Multilevel analysis software accounts for this dependence and in recent years these programs have been widely accepted. Two problems that occur in the practice of multilevel modeling will be discussed. The first problem is the choice of the sample sizes at the different levels. What are sufficient sample sizes for accurate estimation? The second problem is the normality assumption of the level‐2 error distribution. When one wants to conduct tests of significance, the errors need to be normally distributed. What happens when this is not the case? In this paper, simulation studies are used to answer both questions. With respect to the first question, the results show that a small sample size at level two (meaning a sample of 50 or less) leads to biased estimates of the second‐level standard errors. The answer to the second question is that only the standard errors for the random effects at the second level are highly inaccurate if the distributional assumptions concerning the level‐2 errors are not fulfilled. Robust standard errors turn out to be more reliable than the asymptotic standard errors based on maximum likelihood.     

浅议管理审计与公司治理

管理审计是公司内部审计的重要组成部分,是一项基于受托管理(经营)责任关系的以审查管理信息为中心任务的证实行为。公司治理是现代公司制的棱心,是以内部监督为挂心的制度安排,包括权力制衡、激励约束及信息反馈等内在机制。管理审计对于公司治理具有极其重要的作用,应充分发挥它的这种作用。
