失业统计指标比较及其改进

失业问题日益成为宏观经济管理中的重大问题,高估或低估失业率都可能导致政策失当,影响社会稳定和经济发展。中国现行失业统计指标存在诸多问题如失业人员界定狭隘、统计口径仅限于非农业人员、官方公布的数据仅为城镇登记失业率、统计外延过窄、数据时效性差。应本着实事求是、循序渐进、分项统计、时效性的原则完善中国失业统计指标体系,即失业统计指标体系应由单一的城镇登记失业率改为城镇登记失业率和调查失业率共同组成。     

中国省际医疗财政支出效率比较研究——基于DEAMalmqusit指数分析法

基于DEA--Malmquist指数分析法,选择2002-2009年中国30个省（市、自治区）医疗财政投入产出指标为跨期面板数据,分析了省域间医疗财政投入效率的变化差异。结果显示：中国整体的医疗财政支出效率水平辖低。目前仍处于增长状杰。东部地区医疗财砖专出效率相对较高．西部相对较低．中部最低．     

综合英语教学模式研究

本文简要分析了以教师为中心的教学模式之后,指出现有的教学模式已不能适应时代要求,亟须进行教学模式的改革。我们采用以学生为中心,教师为指导的课堂教学模式,以求培养出具有听、说、读、写、译综合能力的英语人才。     

转轨以来中国经济增长质量的综合评价研究

高质量的经济增长既是数量的扩张过程,又是质量的提高过程,是数量扩张与质量提高的统一。自1978—2002年以来,中国经济以年均9.36%的速度增长,经济规模总量迅速扩张。但中国经济增长质量的综合评价结果表明,中国经济增长质量提高与数量扩张并不同步,即转轨以来经济规模总量迅速扩张的同时,并没有带来经济增长质量的同比提高。     

教育均衡视域下城乡学前教师资源配置研究

师资均衡配置是教育公平的核心。采用泰尔指数探究2006-2020年我国幼儿教育专任教师、专科及以上学历教师以及有职称教师资源在城乡的配置差异性状况及主要问题。结果表明我国专任和专科及以上学历幼儿教师资源配置差异性减小,专任数量和学历问题得到有效解决,组间贡献率是总体差异的主要来源,城乡间不公平问题仍存在;城乡有职称教师资源配置差异性增大,不公平问题严重,尤其是乡村内部和城乡间配置问题凸出。对此要从建立幼儿教师职称评选制度、转变乡村园所职业认知、完善城乡教师流动机制等方面缓解配置差异。

工业产业结构高度化水平的基本测评

本文构造了工业产业结构高度化水平评价指标体系,应用该指标体系评价了目前粤、苏、浙、鲁、京五省市的产业结构高度,评价结果显示,体现都市型工业特征的北京地区达到了最高的工业产业结构高度,江苏、广东的工业产业结构高度次之,其差距主要体现在产业间结构高度以及产业结构的持续升级能力。山东、浙江的工业产业结构高度化水平较低,其升级重点应分别在于产业链结构高度和产业间结构高度,另外两省尤需尽快提升产业结构升级转换能力。     

Residual‐Based Block Bootstrap for Unit Root Testing

A nonparametric, residual‐based block bootstrap procedure is proposed in the context of testing for integrated (unit root) time series. The resampling procedure is based on weak assumptions on the dependence structure of the stationary process driving the random walk and successfully generates unit root integrated pseudo‐series retaining the important characteristics of the data. It is more general than previous bootstrap approaches to the unit root problem in that it allows for a very wide class of weakly dependent processes and it is not based on any parametric assumption on the process generating the data. As a consequence the procedure can accurately capture the distribution of many unit root test statistics proposed in the literature. Large sample theory is developed and the asymptotic validity of the block bootstrap‐based unit root testing is shown via a bootstrap functional limit theorem. Applications to some particular test statistics of the unit root hypothesis, i.e., least squares and Dickey‐Fuller type statistics are given. The power properties of our procedure are investigated and compared to those of alternative bootstrap approaches to carry out the unit root test. Some simulations examine the finite sample performance of our procedure.     

Statistical considerations for assessing precision of heterogeneous duplicate measurements: An application to pharmaceutical bioanalysis

Duplicate analysis is a strategy commonly used to assess precision of bioanalytical methods. In some cases, duplicate analysis may rely on pooling data generated across organizations. Despite being generated under comparable conditions, organizations may produce duplicate measurements with different precision. Thus, these pooled data consist of a heterogeneous collection of duplicate measurements. Precision estimates are often expressed as relative difference indexes (RDI), such as relative percentage difference (RPD). Empirical evidence indicates that the frequency distribution of RDI values from heterogeneous data exhibits sharper peaks and heavier tails than normal distributions. Therefore, traditional normal-based models may yield faulty or unreliable estimates of precision from heterogeneous duplicate data. In this paper, we survey application of the mixture models that satisfactorily represent the distribution of RDI values from heterogeneous duplicate data. A simulation study was conducted to compare the performance of the different models in providing reliable estimates and inferences of percentile calculated from RDI values. These models are readily accessible to practitioners for study implementation through the use of modern statistical software. The utility of mixture models are explained in detail using a numerical example.     

"多维切分、开放扩展"原则与索引智能化--编写《民间故事类型索引》的媒介视角

民间故事数量的丰富性与形态的复杂性,决定了任何单向标准的分类皆有其片面性.由此,有必要引入编写<民间故事类型索引>的媒介视角,把纸媒介形态下的索引编写导入智能电子媒介形态,以"多维切分、开放扩展"的编写原则,继承原有索引的成果,充分利用智能电子索引的超文本性和数据库资源,实现相对全面的多维度把握故事,沟通类型与故事文本之间密切的生命关联.
