区域可持续发展及其人口安全策略研究

区域可持续发展是建立在社会、经济、资源、环境对人口系统的支撑之上,关键是要保持人口与社会、经济协调发展,并维持资源、环境对人口发展的持续支撑。基于此,建立了包括人口子系统、社会经济子系统、资源环境子系统和科技制度子系统的区域可持续发展指标体系框架,并用全国各省的横截面数据,对区域可持续发展各系统状态进行因子分析与评价,并根据结果提出区域可持续发展系统的人口安全对策思考。

On Exact Statistical Properties of Multidimensional Indices Based on Principal Components,Factor Analysis,MIMIC and Structural Equation Models

Recent empirical literature has seen many multidimensional indices emerge as well-being or poverty measures, in particular indices derived from principal components and various latent variable models. Though such indices are being increasingly and widely employed, few studies motivate their use or report the standard errors or confidence intervals associated with these estimators. This paper reviews the different underlying models, reaffirms their appropriateness in this context, examines the statistical properties of resulting indices, gives analytical expressions of their variances and establishes certain exact relationships among them.      

Determining the number of factors with potentially strong within-block correlations in error terms

ABSTRACT

We develop methods to estimate the number of factors when error terms have potentially strong correlations in the cross-sectional dimension. The information criteria proposed by Bai and Ng (2002 Bai, J., Ng, S. (2002). Determining the number of factors in approximate factor models. Econometrica 70:191–221.[Crossref], [Web of Science ®] , [Google Scholar]) require the cross-sectional correlations between the error terms to be weak. Violation of this weak correlation assumption may lead to inconsistent estimates of the number of factors. We establish two data-dependent estimators that are consistent whether the error terms are weakly or strongly correlated in the cross-sectional dimension. To handle potentially strong cross-sectional correlations between the error terms, we use a block structure in which the within-block correlation may either be weak or strong, but the between-block correlation is limited. Our estimators allow imperfect knowledge and a moderate misspecification of the block structure. Monte-Carlo simulation results show that our estimators perform similarly to existing methods for cases in which the conventional weak correlation assumption is satisfied. When the error terms have a strong cross-sectional correlation, our estimators outperform the existing methods.     

浙江省劳动收入比重变动的实证研究

本文以浙江省为例,对劳动收入比重变动的机理进行了分析。在机理分析中,对劳动收入比重的变化率进行了分解,得出三个主要因素:系数大小、人均资本及要素偏向型技术进步。与此同时,运用"动态最小二乘法"对浙江省的劳动弹性进行测算,并对浙江省1985-2007年的劳动收入比重变化进行了实证分析。通过研究发现:人均资本增长能够提高劳动收入比重,系数则缩小了资本对劳动收入比重的正向拉动作用,造成浙江省劳动收入比重下降最主要的原因是要素偏向型技术进步,提高私营企业投资占总投资比重以及人均资本存量可以提高浙江省劳动收入比重,而工业化进程加快、FDI以及劳动偏向性技术进步等因素则降低了浙江省劳动收入比重。     

组织行为与制度建构:非领导职务公务人员绩效考核影响因素探析——基于八省问卷调查数据的因子分析

绩效考核作为一种管理工具,对于提升公共组织的效率,建立现代意义上的公务员制度,具有重要意义。现行的《公务员法》明确了公务员绩效考核的地位,使绩效考核具备初步的制度基础,但其制度效力如何,仍然是一个悬而未决的问题。以问卷调查为主要研究方法,基于因子分析的定量技术来分析影响非领导职务公务人员绩效考核实际效果的各类因素,可以发现,考核指标的主观性、程序公正性的缺失、组织中的政治行为以及组织文化,对公务人员对绩效考核的满意度均有明显的影响。     

金融发展和全要素生产率:一个文献回顾

全要素生产率增长是经济可持续增长的重要保证。金融发展理论及其跨国经验研究的一个基本结论是,全要素生产率与金融发展有着重要的联系。作为一个新兴的市场经济国家,中国同时经历了经济增长和以银行中介为主体的金融发展过程。已有中国经验研究文献表明,加快银行体系改革、推动金融发展应该成为中国提升全要素生产率的长期战略选择。     

Review of the effects of Five Factor Model personality traits on network structures and perceptions of structure

We review recent research on Five Factor Model personality and social network analysis to assess how structures develop and are perceived. Extraversion and agreeableness relate consistently to personal but not workplace networks. Extraverts are more likely to seek connections, whereas agreeable individuals receive connections from others. Openness predicts network diversity and is marginally related to position when groups pursue collective goals. Conscientiousness is associated with maintaining certain personal relationships, but is strongly related to central positions in workplace networks. Neuroticism has no consistent relationship with network size or composition, and is differentially related to network positions, depending on the context.     

Analysis of the response structure to a set of questions with large number of scale points: a new combined metric and categorical approach

In the field of social sciences, certain tasks, such as the identification of typologies and the characterization of groups of individuals according to a set of questions, tend to pose a challenge for researchers. Further complications arise if the chosen rating scale is from 0 to 10, since the responses can be treated either as metric or categorical variables. This paper shows that neither treatment is able on its own to capture all the inherent properties of this type of data, and goes on to propose a bicriteria clustering approach, which captures both perspectives and enables the simultaneous analysis of mixed data using multiple tables.
