产业集群成长和升级的制度经济学研究

结合生命周期理论,从制度经济学的角度出发对产业集群的制度成因、产业集群发展和成熟的制度绩效、产业集群的制度风险和产业集群升级的制度创新等进行深入的剖析,得出结论:要使产业集群保持长久的生命力,构建集群制度创新系统是十分重要的。     

论可持续发展的代价调控与实现

可持续发展战略是人类在面临一系列冲突和矛盾时所作的一种选择,任何一种选择都不会是无代价的,可持续发展战略也不例外。面对可持续发展选择下的代价及其产生的根源,我们可以做积极的调控努力,一方面可以从发展伦理学中汲取有益的启示,同时在代价调控的宏观目标设定上要保持代价与创价的博弈均衡。     

浅议当前农村养老保障体系中的缺陷和问题

目前农村家庭养老矛盾重重 ,面临农村养老保障由家庭养老向社会养老逐渐过渡的问题。在统筹社会养老基金时 ,应考虑农村养老保障体制转换成本问题 ,应由集体经济和国家负担部分转换成本。家庭养老以精神激励为主 ,但也要实行有效的监督。社会养老基金统筹可采用浮动制的收费办法 ,以弥补保费收缴水平偏低的矛盾     

工业革命时期英国卫斯理宗(1740-1840)

卫斯理宗(又称循道宗)诞生于18世纪的英国,它是国教牧师约翰·卫斯理创立的,卫斯理宗既是一场宗教革命--福音主义运动,又是一场声势浩大的群众运动,广泛地影响了英国工业革命前后时期的社会生活,具有巨大的社会整合功能.     

论马克思的产权理论

产权是财产主体对财产所拥有的排他性、归属性的关系和权利,体现了人与人之间的经济关系或经济权利.产权由所有制决定,受到一定的法律保护,体现了一定的历史范畴.     

论当代中国政府经济职能的战略性重构

政府经济职能战略性重构的内涵是 :防止、纠补“政府失灵”和克服、弥补“市场失灵”。相应的对策 :一是限制和约束政府权力和职能 ,包括以政企分开为突破口 ,加快现代企业制度建设 ;规范政府干预职能及行为 ;加强对政府调控行为的监督 ;在政府经济职能重构的基础上 ,精简政府机构等。二是提升政府能力特别是宏观调控能力 ,包括财政宏观调控能力、金融宏观调控能力和行政组织调控能力 ;提高政府决策的科学化程度 ;将成本—效益观念和竞争机制引入政府调控的某些领域等 ,从而积极、适度、有效地行使政府对市场运作的宏观调控职能 ,充分发挥政府干预与市场调节二元机制的优势互补作用     

Choice Functions: Rationality re-Examined

On analyzing the problem that arises whenever the set of maximal elements is large, and a selection is then required (see Peris & Subiza 1998), we realize that logical ways of selecting among maximals violate the classical notion and axioms of rationality. We arrive at the same conclusion if we analyze solutions to the problem of choosing from a tournament (where maximal elements do not necessarily exist). So, in our opinion the notion of rationality must be discussed, not only in the traditional sense of external conditions (Sen 1993), but in terms of the internal information provided by the binary relation.     

Characterizations based on conditional expectations

For given real functionsg andh, first we give necessary and sufficient conditions such that there exists a random variableX satisfying thatE(g(X)|X≥y)=h(y)r _x (y),∀y ∈ C _x , whereC _x andT _X are the support and the failure rate function ofX, respectively. These extend the results of Ruiz and Navarro (1994) and Ghitany et al. (1995). Next we investigate necessary and sufficient conditions such thath(y)=E(g(X)|X≥y), for a given functionh. Support for this research was provided in part by the National Science Council of the Republic of China, Grant No. NSC 86-2115-M-110-014 and NSC 88-2118-M-110-001     

A class of weighted dependence measures for bivariate failure time data

This paper considers a class of summary measures of the dependence between a pair of failure time variables over a finite follow-up region. The class consists of measures that are weighted averages of local dependence measures, and includes the cross-ratio-measure and finite region version of Kendall's τ; recently proposed by the authors. Two new special cases are identified that can avoid the need to estimate the bivariate survivor function and that admit explicit variance estimators. Nonparametric estimators of such dependence measures are proposed and are shown to be consistent and asymptotically normal with variances that can be consistently estimated. Properties of selected estimators are evaluated in a simulation study, and the method is illustrated through an analysis of Australian Twin Study data.     

A general central limit theorem and a subsampling variance estimator for α‐mixing point processes

We establish a central limit theorem for multivariate summary statistics of nonstationary α‐mixing spatial point processes and a subsampling estimator of the covariance matrix of such statistics. The central limit theorem is crucial for establishing asymptotic properties of estimators in statistics for spatial point processes. The covariance matrix subsampling estimator is flexible and model free. It is needed, for example, to construct confidence intervals and ellipsoids based on asymptotic normality of estimators. We also provide a simulation study investigating an application of our results to estimating functions.
