The Establishment and Application of a Labor Quality Index: The Case of Taiwan’s Manufacturing Industry

The labor quality index (LQI) not only serves as an important reference for monitoring the progress of the sustainable development of a country, but it can also serve as an important parameter for economic analysis. To compile such an index for Taiwan, we conducted two large-scale surveys of 1000 major enterprises and 844 union leaders, respectively, to determine the appropriate weights for each key factor. We also searched for all the relevant statistics that were used to calculate the weighted sum of the 25 sub-indexes, in order to compile a LQI for Taiwan’s manufacturing industries covering the period from 1990-2000. Our calculations show that this LQI rose from 80.2 in 1990 to 117.5 in 2000, which reflected an impressive 37.3% increase in just one decade. This rate of growth has, however, been slowing down since 1997. Our results indicate that the LQI provides a valuable indicator for monitoring the enhancement of labor quality in this society.

Asymptotic Theory of Outlier Detection Algorithms for Linear Time Series Regression Models

Outlier detection algorithms are intimately connected with robust statistics that down‐weight some observations to zero. We define a number of outlier detection algorithms related to the Huber‐skip and least trimmed squares estimators, including the one‐step Huber‐skip estimator and the forward search. Next, we review a recently developed asymptotic theory of these. Finally, we analyse the gauge, the fraction of wrongly detected outliers, for a number of outlier detection algorithms and establish an asymptotic normal and a Poisson theory for the gauge.     

基于熵理论的河北省可持续发展水平评价研究

根据2000—2009年国家统计年鉴中河北省的有关数据，选取有代表性的指标，构造评价可持续发展水平的指标体系，并采用熵理论确定各指标的权重，以观察近10年来河北省经济社会可持续发展的具体情况。实证研究结果表明：河北省正逐渐迈向可持续发展的道路,但任重道远。根据省际具体情况，在实证研究的基础上，就河北省经济社会的长期可持续发展提出了若干建议。     

可行能力与农民工的福利状况评价

基于辽宁省沈阳市农民工调查数据,应用森的可行能力理论和模糊数学方法对农民工的福利状况进行整体评价。结果发现,农民工福利水平的总模糊指数为0.365,处于较低水平。分指标看,健康状况方面的福利状况处于较高水平,居住环境和精神感受方面的福利状况处于中间水平,其它功能性指标的福利水平较低。在影响农民工福利的主要因素中,工作环境和防护性保障的改善对提升农民工福利影响最大。运用OLS回归模型对农民工的福利状况进行扩展分析,发现农民工群体内部存在较强的异质性,并且不同特征的农民工群体福利水平相差很大。     

如何恰当地界定中国高技术制造业的统计范围

在简要考察美国商务部和OECD等国际组织对高技术产业的界定方法及其合理性的基础上,对中国官方界定的高技术产业统计范围及其演变过程进行了梳理,对能否从高附加值、高成长性和高效益等特征出发筛选高技术产业以及如何恰当地界定中国高技术产业的统计范围做了进一步的讨论。研究结果认为,应从中国所处的经济发展阶段和整体的技术水平出发,以"R&D经费强度"和"科技人员比重"二者之一高于中国制造业的平均水平为标准,确定中国高技术制造业的统计范围。     

网络舆情评估EHA三维指标体系的构建

随着网络在我国的兴起和发展,网络舆情的评估已经成为评价和预警社会形势的重要指标.通过对现有舆情研究的调研和分析,得出由舆情要素、舆情热度和舆情活性3个一级指标、7个二级指标以及14个三级指标共同构建的网络舆情评估的EHA三维指标体系,并对各级指标给出了详尽的分析和阐述.     

Bayesian nonparametric modelling of the link function in the single-index model using a Bernstein–Dirichlet process prior

This paper proposes the use of the Bernstein–Dirichlet process prior for a new nonparametric approach to estimating the link function in the single-index model (SIM). The Bernstein–Dirichlet process prior has so far mainly been used for nonparametric density estimation. Here we modify this approach to allow for an approximation of the unknown link function. Instead of the usual Gaussian distribution, the error term is assumed to be asymmetric Laplace distributed which increases the flexibility and robustness of the SIM. To automatically identify truly active predictors, spike-and-slab priors are used for Bayesian variable selection. Posterior computations are performed via a Metropolis-Hastings-within-Gibbs sampler using a truncation-based algorithm for stick-breaking priors. We compare the efficiency of the proposed approach with well-established techniques in an extensive simulation study and illustrate its practical performance by an application to nonparametric modelling of the power consumption in a sewage treatment plant.     

数字经济发展的评估指标体系研究——基于投入产出视角

发展数字经济是我国重要国策,对其评估指标体系的研究受到多方关注,但目前我国数字经济测度仅仅局限于数字化产业和数字化创新,尚未形成一个完整、系统的数字经济评价指标体系。文章在引入治理环境的基础上,基于经济学上的投入产出视角探讨我国数字经济发展的有效测度方法,在研究数字经济的发展效应中新添了数字化治理和数字知识型人才供给两项指标,构建了一套基于投入产出视角的数字经济发展评价指标体系,为衡量数字经济发展提供了一个系统的体系。为提升数字治理现代化水平,更好发挥数字经济在促进经济高质量发展中的作用提供了实践意义和政策参考。
