基于信任的供应链治理机制研究

针对供应链的治理难题,提出信任具有决策、协调、约束和简化等功能,信任机制是非垂直管理体系特别是供应链的理想治理工具,由此建构了多层次的供应链信任治理结构体系。     

中国经济增长模式转型：供给结构视角分析

公共产品供给机制创新及其法律规制

供给机制不完善是造成公共产品供求矛盾的一个根本原因。现行单向的决策机制、一元的供给主体和垄断性供给方式带来诸多弊端。创新供给机制,建立自下而上多利益中心决策机制、建立包括政府、市场和第三部门在内的多元化供给主体机制和供给方式。法律规制中应赋予不同利益组织参与决策权,主体间供给责任分配。规制法律既有公法还包括私法,并遵循双重利益平衡和充分竞争原则。

On an adaptive version of the Metropolis–Hastings algorithm with independent proposal distribution

In this paper, we present a general formulation of an algorithm, the adaptive independent chain (AIC), that was introduced in a special context in Gåsemyr et al . [ Methodol. Comput. Appl. Probab. 3 (2001)]. The algorithm aims at producing samples from a specific target distribution Π, and is an adaptive, non-Markovian version of the Metropolis–Hastings independent chain. A certain parametric class of possible proposal distributions is fixed, and the parameters of the proposal distribution are updated periodically on the basis of the recent history of the chain, thereby obtaining proposals that get ever closer to Π. We show that under certain conditions, the algorithm produces an exact sample from Π in a finite number of iterations, and hence that it converges to Π. We also present another adaptive algorithm, the componentwise adaptive independent chain (CAIC), which may be an alternative in particular in high dimensions. The CAIC may be regarded as an adaptive approximation to the Gibbs sampler updating parametric approximations to the conditionals of Π.     

A bayesian estimator for the dependence function of a bivariate extreme‐value distribution

Any continuous bivariate distribution can be expressed in terms of its margins and a unique copula. In the case of extreme‐value distributions, the copula is characterized by a dependence function while each margin depends on three parameters. The authors propose a Bayesian approach for the simultaneous estimation of the dependence function and the parameters defining the margins. They describe a nonparametric model for the dependence function and a reversible jump Markov chain Monte Carlo algorithm for the computation of the Bayesian estimator. They show through simulations that their estimator has a smaller mean integrated squared error than classical nonparametric estimators, especially in small samples. They illustrate their approach on a hydrological data set.

我国纺织品业应对国际贸易中绿色壁垒的措施

近年来,在纺织品国际贸易中,技术贸易壁垒中的绿色壁垒已逐渐发展成为主要的非关税贸易壁垒。越来越多的发达国家在实行新贸易保护主义时采用绿色壁垒,以防止破坏生态环境和人类健康为由,制定一系列技术标准,对我国纺织品的出口形成越来越大的阻碍。因此,我国政府和企业应该联合起来,采取一些有效的措施来应对绿色壁垒,发展我国纺织品业的对外贸易。     

A Non-parametric Frailty Model for Temporally Clustered Multivariate Failure Times

Abstract A model is introduced here for multivariate failure time data arising from heterogenous populations. In particular, we consider a situation in which the failure times of individual subjects are often temporally clustered, so that many failures occur during a relatively short age interval. The clustering is modelled by assuming that the subjects can be divided into ‘internally homogenous’ latent classes, each such class being then described by a time‐dependent frailty profile function. As an example, we reanalysed the dental caries data presented earlier in Härkänen et al. [Scand. J. Statist. 27 (2000) 577], as it turned out that our earlier model could not adequately describe the observed clustering.
