基于资源协同的企业能力提升机理研究

将协同学理论应用于企业资源及其能力的研究,通过对哈肯协同学原理的分析及扩展研究,构建资源相互匹配与不匹配时的协同模型,来分析企业各资源要素之间协同状况对其发挥效能程度的影响,以此提出资源要素是企业能力的基础,资源协同是促进企业能力提升的源动力。由探讨可知,资源匹配程度与资源协同稳定点之间存在逻辑关系,阐释了资源效能发挥和企业能力提升之间的关系。

Indirect estimation of randomized generalized autoregressive conditional heteroskedastic models

The class of generalized autoregressive conditional heteroskedastic (GARCH) models can be used to describe the volatility with less parameters than autoregressive conditional heteroskedastic (ARCH)-type models, their distributions are heavy-tailed, with time-dependent conditional variance, and are able to model clustering of volatility. Despite all these facts, the way that GARCH models are built imposes limits on the heaviness of the tails of their unconditional distribution. The class of randomized generalized autoregressive conditional heteroskedastic (R-GARCH) models includes the ARCH and GARCH models allowing the use of stable innovations. Estimation methods and empirical analysis of R-GARCH models are the focus of this work. We present the indirect inference method to estimate the R-GARCH models, some simulations and an empirical application.     

Stable growth in native‐dependent multistate population dynamics

Users of multistate life tables and projections have recognized that the Markovian assumptions underlying such models are unduly restrictive and should be relaxed whenever data permit. Efforts to include the influences of previous occupancies have included the incorporation of place‐of‐birth dependence. This paper addresses the stable growth properties of such generalized multistate models. It shows how place‐of‐birth‐specific stable growth measures can be calculated without projection simply by solving the characteristic equation. An example using Canadian data illustrates the argument.     

Distribution of the coates-diggle test statistic in case of replicated observations

A closed form expression for the distribution of a test statistic for comparing the spectral densities of stationary processes is given. This test statistic was introduced by COATES and DIGGLE ( 1986 ) for the unreplicated case and has been extended to the case of replicated observations by POTSCHER and RESCHENHOFER ( 1988 ). A simple method for computing approximate critical values in case of large numbers of replications is also provided. As a by-product an explicit expression for the distribution function of the range of independent variates each distributed as the logarithm of an F-variate i.e up to a factor of 2 each followin Fishers z-distriution is obtained     

Some properties of modified integrated squared error estimators for the stable laws

The estimation procedure of Paulson, Holcomb and Leitch (1975) for the parameters of the stable laws is shown to be similar in spirit to the modified X²minimum procedure. This observation suggests that a class of modified integrated squared error procedures may be developed for the stable laws as well as much more generally. For the stable case, some influence curves, asymptotic covariances, and efficiencies are given, and the robustness of maximum likelihood estimators is discussed.     

新冠疫情下我国人力资源服务效率分析

新型冠状病毒疫情给我国国民经济生产带来巨大影响,国家多措并举稳步推进企业复工复产,人力资源服务发挥着至关重要的作用。运用DEA和Malmquist指数方法分析疫情状态下我国人力资源服务的效率发现:综合效率整体表现良好,部分时间段内投入冗余致使资源浪费以及产出不足影响了服务效率,技术变化对全要素生产率造成较大影响,迁出人口、规模以上企业复工率和疫情环境对服务效率的影响最大。总结此次经验,将有助于完善我国人力资源服务模式、提升信息化水平和推动公共就业服务均等化进程。     

Bertrand双寡头对上游供应商行为的演化博弈分析

针对目前普遍存在的供应链上下游由于力量不对等而导致的强势一方向弱势一方转嫁成本的现状,研究力量不对等供应链上零售寡头对上游供应商的行为策略.建立竞争环境下的Bertrand寡头模型,得到双寡头采用不同行为策略的支付矩阵.在此基础上,应用演化博弈论中双种群演化模型进行分析,得到双寡头对上游供应商行为的演化稳定均衡.研究结果表明,由于零售寡头之间的竞争,随着寡头对供应商利益侵占数额的增大,双寡头对上游供应商的均衡策略依次为(转嫁成本,转嫁成本)、(转嫁成本,不转嫁成本)以及(转嫁成本,不转嫁成本)与(不转嫁成本,转嫁成本)共存的情况.同时进一步指出市场容量、寡头实力差距、侵占度等参数变化对演化稳定均衡的影响.
