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。

微波反馈放大器匹配及增益带宽的研究

本文介绍的是小信号微波反馈放大器的分析与综合。放大器是采用通常的增益级的框图,并取并联反馈。文中提供全部网络元件值的估算和预测闭环宽频带增益、带宽和双端口的匹配值。简述匹配值与增益用图解法的权衡。最后描述了综合方法并举例说明设计实例。     

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.
