关于增列审计学一级学科的设想

审计是党和国家、各类组织监督体系中的重要组成部分，是一种依法监督经济权力行使的制度安排，具有鲜明的法学学科属性。推进国家治理体系和治理能力现代化，迫切需要构建中国特色社会主义审计学科体系、学术体系和话语体系，构建现代审计人才培养体系。审计学具有确定的研究对象，形成了相对独立、自成体系的理论、知识基础和研究方法，已经具备设置为一级学科的条件，应该在法学学科门类下增列审计学一级学科。     

拆分招标的供应商数量研究

许多企业在采购时,常常将整笔业务拆分为两个合同:较大的第一合同和较小的第二合同,通过分批二级价格封闭式招标来选择不同的供应商供货。本文通过建立分批招标模型分析了供应商的投标策略和买方的采购策略,得出了当参加第一合同竞标的供应商数目和第二合同新引入的供应商数目满足一个不等式时,拆分招标的采购成本小于整体招标的采购成本,并且指出了拆分比例对拆分招标的采购成本的影响。     

股票投资价值的灰色多层次评价

股票投资价值的评估是一个多目标、多层次和多因素组成的复杂系统,对其进行综合评价对投资决策是至关重要的。本文根据灰色系统理论,以灰色关联度为测度,提出了股票投资价值的灰色多层次评价模型,并通过实证研究和理论分析,表明该模型对投资者的决策有较高的参考价值。

中低层灵活就业群体的异同分析与对策

中低层灵活就业群体主要由下岗工人与农民工组成,他们是就业群体中的弱势群体,如何对他们进行更好的制度安排,促进灵活就业的发展,对于缓解就业压力有着积极的意义.中低层灵活就业中的两大类群体在就业方面既存在共性又存在区别,对此进行分析能更好地促进他们实现灵活就业,并为政府采取有针对性的措施提供参考.

Monotonicity of Rank Statistics in some Non–parametric: Testing Problems

For some non–parametric testing problems (one–sided two–sample problem, k –sample trend problem, testing independence against positive dependence) a partial ordering, denoted by ≥, over the alternatives is defined. This partial ordering expresses the strength of the deviation from the null–hypothesis. All familiar rank tests turn out to become more powerful under "increasing" alternatives; that is, all familiar rank statistics preserve the ordering stochastically in samples whenever it is present between underlying distributions. As a tool, the sample equivalence of ≥ is introduced as a partial ordering over pairs of permutations. Functions, defined on pairs of permutations, which preserve this ordering are studied.     

上市公司如何在非理性世界中确定股权回报率

确定股权回报率是进行长期投资决策的关键步骤,但在现实非理性世界中难以直接运用传统财务理论所推荐的资本资产定价模型来确定股权回报率。针对FAR与NEER方法,本文首先探讨这两类方法的理论依据并揭示其本质内涵,然后说明:在非理性世界中,如果上市公司管理者追求公司价值最大化目标,那么就应该基于公司项目的基本风险来确定股权回报率;相反地,如果管理者追求近期股价最大化,那么就应该基于市场投资者的预期来确定股权回报率。     

Modelling of repairable systems with various degrees of repair

The availability of a stochastic repairable system depends on the failure behaviour and on repair strategies. In this paper, we deal with a general repair model for a system using auxiliary counting processes and corresponding intensities which include various degrees of repair (between minimal repair and perfect repair). For determining the model parameters we need estimators depending on failure times and repair times: maximum likelihood (ML) estimator and Bayes estimators are considered. Special results are obtained by the use of Weibull-type intensities and random observation times.     

Testing equality of variances in the analysis of repeated measurements

The problem of comparing the precisions of two instruments using repeated measurements can be cast as an extension of the Pitman-Morgan problem of testing equality of variances of a bivariate normal distribution. Hawkins (1981) decomposes the hypothesis of equal variances in this model into two subhypotheses for which simple tests exist. For the overall hypothesis he proposes to combine the tests of the subhypotheses using Fisher's method and empirically compares the component tests and their combination with the likelihood ratio test. In this paper an attempt is made to resolve some discrepancies and puzzling conclusions in Hawkins's study and to propose simple modifications.
The new tests are compared to the tests discussed by Hawkins and to each other both in terms of the finite sample power (estimated by Monte Carlo simulation) and theoretically in terms of asymptotic relative efficiencies.
