亚洲工厂及关联度分析

依据亚洲零部件贸易数据,作者采用了依存比率的方法对亚洲工厂的规模、工厂内部以及同美国之间的相互依存关系进行了研究。研究结果发现,亚洲工厂的规模超过北美洲和欧洲工厂,成为了世界上最大的工厂。亚洲零部件内部贸易额及比重超过了欧盟,这说明亚洲生产的一体化程度更高。从零部件进出口规模角度看,亚洲地区的经济体均高度依赖亚洲工厂的活动,而亚洲工厂对中国的依存度则最高,对日本的依赖程度只排在第三位,这说明中国是亚洲工厂的核心平台。美国在亚洲贸易中的重要性主要体现为中国的最终产品出口对美国市场存在严重依赖,而亚洲主要经济体对中国市场的出口已经超过对美国的出口,亚洲工厂对于美国的依赖程度并不高,远远低于亚洲工厂对中国内地和中国香港的依赖。相反,美国对亚洲工厂的依赖程度则远高于亚洲工厂对美国的依赖。

非线性网络的故障诊断

本文讨论了将K故障证实法推广于具有不可及节点的非线性网络的多故障诊断问题。提出了一种新的故障检验和分析方法,通过诊断实例,说明了本方法的可行性。     

Significant Issues for the Future: Some Additional Perspectives

The rational elements of management dominated the questions raised by our Editorial Board members in the previous issue of JPIM when they offered their ideas in, "Significant Issues For the Future of Product Innovation." In this article, the discussion is continued with some other Board members but this time the human side of managements gets its due attention. The issues presented here add to the picture of complexity that is the reality of product innovation but they also may provoke the thinking that can lead to an improvement in management performance.     

Significant Issues for the Future of Product Innovation

What's happening in the world of product innovation? What are the tough issues that managers are facing? And what's going to happen in the remaining years of this decade? In this article, several members of the Editorial Board of The Journal of Product Innovation Management offer their ideas about where the important problems lie. This is the fodder for a good round table discussion and through the medium of this journal we'll engage in such a discussion in this and a subsequent issue.
