本文收集了从开始授予博士学位以来至2004年我国经济与管理类统计学博士论文。对这些博士论文的选题及其研究内容进行考察与点评,分析其变动的轨迹和特点。     

Congruence in the assessment of service quality between employees and customers: A study of a public health care delivery system

Using social information processing theory, we examined the congruence between employee and customer assessments of organizations' service quality. The setting was a public health care delivery system. Contrary to expectations, employee assessments of service quality were lower than those of their customers. Also unexpectedly, employees with professional training had less congruent assessments than other employees. As expected, employees with longer tenure and those in departments with stronger customer service work climates had more congruent assessments relative to their customers. The results have implications for both management theory and for managers interested in developing customer-centered organizations.     

知识产权评估折现率的研究

在知识产权评估的常用方法中,收益法具有重要地位。而折现率是收益法中的重要参数之一,其细微的差异将会导致评估结果的显著不同。知识产权折现率的现有确定方法存在诸多缺陷。本文在分析知识产权折现率的特点与构成的基础上,创建了基于模糊数学理论、集值统计原理和层次分析法的知识产权折现率估算新模型——扩展资本成本模型,并通过评估案例探讨了该模型在实践中的应用。     

所有权原则、FDI利得与中美贸易差额

在发达国家大量通过FDI参与国际商业活动的背景下,基于所有权原则的贸易收支统计能够捕捉FDI对贸易收支的影响,从而反映出各国参与国际商业活动的实际利得。根据测算,美国自2000年以来外国直接投资净收益约占其贸易赤字的25%~30%。同时基于所有权统计原则调整后发现,中美贸易顺差根源于FDI,这与现有有关中美贸易不平衡的研究结论大相径庭。     

Decision theoretic estimation using record statistics

We consider the problem of estimating the scale parameter θ of the shifted exponential distribution with unknown shift based on a set of observed records drawn from a sequential sample of independent and identically distributed random variables. Under a large class of bowl-shaped loss functions, the best affine equivariant estimator (BAEE) of θ is shown to be inadmissible. Two dominating procedures are proposed. A numerical study is performed to show the extent of risk reduction that the improved estimators provide over the BAEE.     

建立民营经济统计的若干问题

最近几年以广东、江浙地区为代表的经济发达地区都是通过民营化战略而实现经济腾飞的.随着民营经济的迅速发展,其在国民经济中的地位愈发凸显,建立民营经济统计指标体系势在必行,这不仅是"中国特色"经济统计的要求,也是民营经济发展本身的需要.为此,必须统一对民营经济界定,从民营经济规模、水平、速度,民营经济对国民经济的贡献等方面构造民营经济统计指标体系,对民营经济的发展过程和状况进行经常的、制度性的反映和监督.     

加强和改进能源统计工作的思考

降低单位GDP能耗列入＂十一五＂期间的考核指标之后,能源统计数据受到了社会各界的高度关注。分析了当前中国能源统计制度方法实施中存在的矛盾问题,结合日常统计和经济普查工作经验,提出了改进和加强能源统计的建议,为提高中国能源统计数据质量提供决策参考。     

A statistical and probabilistic analysis of popular lottery tickets

We investigate statistical and probabilistic aspects of a data set of 2588 lottery tickets purchased for the German 6/49 lottery drawing of 16.10.1993 in Baden–Württemberg. Roughly speaking, each of these combinations was chosen at least 50 times above average. 288 of these most popular tickets represent past winning numbers (or modifications thereof) from various lotteries. The vast majority of the remaining tickets is filled out from aesthetic points of view. In this respect, some new random variables are introduced and studied.     

The Current Position of Statistics: A Personal View

Some current aspects of statistical work are reviewed under three broad headings, applied probability modelling, design of investigations and statistical analysis and interpretation of data. The emphasis is on applications in science and science-based technology, although some incidental comments are made about statistics in public affairs. While no technical details are given, there is some discussion of potential fields for development. The choice of topics reflects the author's personal interests.     

铁路行包运量分布的统计分析

近年来,我国行包运输发展很快,但是行包运量分布不均衡,逐渐呈现出集中化的趋势。通过对1997年—2001年行包办理站的数量、份额及运量变化的分类统计,说明行包运量集中化已形成趋势,同时分析了行包集中化车站的分布及地域分布特征。其结果对我国行包运输的市场营销及体制改革有参考价值。
