深入贯标确保质量体系认证的有效性

贯标是认证的前提,要确保认证的有效性,必须提高贯标的有效性.企业获证后的效果不同,与其贯标的深入程度有直接的关系.贯标是确保企业认证有效性的关键所在.提高贯标的有效性,应做到领导带头、全面发动;系统学习、全面理解;联系实际、把握重点;长期坚持、不断深入.     

Evolutionary choice of markets

We consider an economy where a finite set of agents can trade on one of two asset markets. Due to endogenous participation the markets may differ in the liquidity they provide. Traders have idiosyncratic preferences for the markets, e.g.due to differential time preferences for maturity dates of futures contracts. For a broad range of parameters we find that no trade, trade on both markets (individualization) as well as trade on one market only (standardization) is supported by a Nash equilibrium. By contrast, whenever the number of traders becomes large, the evolutionary process selects a unique stochastically stable state which corresponds to the equilibrium with two active markets and coincides with the welfare maximizing market structure.

Heterogeneity vs. externalities in technological competition: A tale of possible technological landscapes

The article presents a stochastic interaction model based on Gibbs random fields to analyze technological competition in a population of heterogeneous adopters with local or global externalities. The relationships between both heterogeneity and externalities and imperfect and asymmetric information are first emphasized. When local externalities and heterogeneity coexist, the technological landscapes of the industry are then shown to depend on the relative influence of these two parameters, with a phase transition: technologies coexist either in approximately equal market shares when heterogeneity is high enough or with one of the technologies only surviving in technological niches when local externalities dominate. Niches do also spontaneously appear: technological options survive in economic space due to the existence of some amount of heterogeneity among agents. On the contrary, when global externalities are added, pure standardization almost always occurs. We finally argue that different public policies should be designed so as to fit with different technological landscapes.

标准化的宏观指导和方法创新

阐述了标准化、标准和标准系统的定义，对标准化的过程模式和发展模式加以分析，并指出：现行的标准系统基本不具备完善的信息反馈功能，标准化管理机构对标准颁布后的实施状况不清楚，这已成为标准系统控制的突出矛盾。提出两个值得探讨的问题：一是标准化管理系统必须具有能使信息集中的统一的功能；二是现有的机构和系统应把标准信息反馈作为重要任务。

Global purchasing strategy: Conceptualization and measurement

In this paper we introduce Global Purchasing Strategy (GPS) as an explanatory construct of global purchasing performance. GPS is embedded in a contingent resource-based view. The construct is conceived as the driving force behind the strategy-organization alignment. GPS is conceptualized along four dimensions: the configuration of the global purchasing process, the standardization of the global purchasing process, the standardization of product-related characteristics and the standardization of the purchasing staff organization. We develop the GPS scale and test it on a sample of 151 internationally purchasing firms. The analytic results show evidence of both reliability and validity. We propose a general model of global purchasing performance with GPS as a central mediating construct.
