统计监督是我国政府统计机构的三大职能之一。党的十八大以来,新时代统计监督职能作用得到进一步发挥,统计监督规范化、制度化、法治化水平持续提升。本文系统梳理了我国统计监督职能内涵的拓展深化过程,分析其随经济社会发展目标演进深化的实践逻辑基础,通过建立统计法治监督生态体系,使用现代信息技术手段进行全流程统计数据质量监督,发挥支撑理论创新和科学决策作用三个实例,对新时代统计监督实践探索进行方法论层面的提炼。从实现路径来看,新征程上应进一步发挥统计监督协同配合机制作用,加强对高质量发展情况的统计监督,以现代化统计监督体系全方位支撑中国式现代化发展。 相似文献

文章基于系统性风险指数SRISK方法,结合我国金融机构的实际上市情况,利用DCC-GARCH模型,分别推导了A股、H股的长期资本短缺公式,并计算SRISK实际数值.然后以上市银行、保险、证券等金融机构等的交易数据为样本,确定了金融机构系统重要性的排名,并将其与基于同一分析框架的MES分析法进行对比分析.结果发现,度量我国金融机构的系统重要性,需要在MES分析的基础上,结合动态相关性和波动性,根据SRISK模型法评估排名.我国金融机构的系统重要性层次分明,保证了监管机构宏观审慎的有效性. 相似文献

国民经济核算对于不少读者,其中也许有不少工作在第一线的统计人员来说,它的重要作用可能是难以理解的,但是它作为广大统计人员最终的成果,在国家生活与发展中具有独特的作用,仅想借《中国统计》来谈一谈这项工作的重要性。国民经济核算是反映国民经济运行状况的有效工具国民经济是一个极其复杂的运行系统,不同部门,不同环节之间存在着复杂的经济联系,准确地了解和把握这个系统是不容易的,需要借助一种行之有效的工具,国民经济核算就是这样一种工具。它通过一系列科学的核算原则和方法把描述国民经济各个方面的基本指标有机地组织… 相似文献

Abstract In the area of goodness-of-fit there is a clear distinction between the problem of testing the fit of a continuous distribution and that of testing a discrete distribution. In all continuous problems the data is recorded with a limited number of decimals, so in theory one could say that the problem is always of a discrete nature, but it is a common practice to ignore discretization and proceed as if the data is continuous. It is therefore an interesting question whether in a given problem of test of fit, the “limited resolution” in the observed recorded values may be or may be not of concern, if the analysis done ignores this implied discretization. In this article, we address the problem of testing the fit of a continuous distribution with data recorded with a limited resolution. A measure for the degree of discretization is proposed which involves the size of the rounding interval, the dispersion in the underlying distribution and the sample size. This measure is shown to be a key characteristic which allows comparison, in different problems, of the amount of discretization involved. Some asymptotic results are given for the distribution of the EDF (empirical distribution function) statistics that explicitly depend on the above mentioned measure of degree of discretization. The results obtained are illustrated with some simulations for testing normality when the parameters are known and also when they are unknown. The asymptotic distributions are shown to be an accurate approximation for the true finite n distribution obtained by Monte Carlo. A real example from image analysis is also discussed. The conclusion drawn is that in the cases where the value of the measure for the degree of discretization is not “large”, the practice of ignoring discreteness is of no concern. However, when this value is “large”, the effect of ignoring discreteness leads to an exceded number of rejections of the distribution tested, as compared to what would be the number of rejections if no rounding is taking into account. The error made in the number of rejections might be huge. 相似文献

本文将消费习惯引入Lucas (1987)模型,采用农村五等份收入户的人均消费数据进行数值模拟,结果发现: 消费增长比消费平稳更重要,且收入等级越高,这种相对重要性就越突出。相对风险规避系数一定时,两类福利成本之比随习惯强度变化的轨迹呈倒U型; 习惯强度一定时,两类福利成本之比随相对风险规避系数的增大而递减。相对于其他等级的收入户,促进消费增长的经济政策为高收入户带来相对较多的福利,而平抑消费波动的经济政策能为低收入户带来较多的福利。因此,政府在促进农村居民消费增长的同时,也应重视消费波动给低收入群体造成的福利成本。 相似文献
