根据文献资料整理“产业化”与“产业结构” 不同的内涵。 试述产业组织理论的由来。
最初把产业组织概念引入经济学,并提出其研究方向的是新古典学派经济学家马歇尔。他的名著《经济学原理》,出版于1890年,在这本书的第四篇-生产要素:土地、劳动、资本和组织中,他研究了产业组织。他指出,组织可以提高效率,增加经济效率,并提出:分工能提高效率;专门工业集中于特定的地方,能提高效率;大规模生产,也能提高效率。该书所提出的规模经济和竞争矛盾(即后人称为“马歇尔冲突”),后来成为产业组织理论探索的两个核心论题。

何谓产业组织?其 “产业”的含义是什么?
产业组织作为提供同类产品或服务的企业市场关系的集合体,以是否提供同一或者有密切替代关系的产品为准则;划分不同企业的不同产业归属;产业组织中所讲的“产业”范围较小,一般是指提供同一或者有替代关系的同类商品的企业在同一市场上的集合。

简要说明产业组织理论与微观经济学的关系与区别。
1.微观经济学研究家庭(消费者)行为和企业(生产者)行为,产业组织理论仅研究企业行为,不研究家庭行为。
2.微观经济学对完全竞争、垄断、垄断性竞争和寡头垄断这四种市

?Rubber Keypad Research Report 第一章 问题的提出
一. Out of Spec问题.
一直以来, 很 多Rubber Keypad来货 Out of Spec, 包括Force, Click等导致一系列 的品质问题.一方面由于模具生产维修造成的变化及老化; 另一方面由于我公司部分 图纸规定的Spec不恰 当, Vendor根本做不到或者很 难做到. 例如某Model Keypad P/N: 39-4033, 图纸规定AF值为135(20, RF为90(10, 未规定Click值,Vendor做不到. 二. 对Silicone Rubber Keypad的认识.
长期以来, 我们对Silicone Rubber Keypad弹力曲线缺乏认识, 对Tooling的制作 和维护,对 Rubber Keypad成型 工艺等认识不深, 这需 要我们全面地, 深层地认识它. 三. 期望对一些长期以来, 悬而未的问题进行解. 如我公司RMA机Rubber Keypad
