基本放大电路动态分析技巧

基本放大电路的动态分析是模拟电子技术教学中的一个重点,同时也是一难点。笔者在多年的教学中总结出一套基本放大电路动态分析的一般方法,在画放大电路的微变等效电路时使用了一定的技巧,使各种基本放大电路的微变等效电路形式一致,通过其求电压放大倍数、输入电阻、输出电阻等参量极其容易,实践证明学生容易掌握,化解了基本放大电路动态分析的难点。     

基于需求冲击分析的产业集群治理机制

本文立足于对产业集群组织特性的再认识,分析了产业集群与网络组织的相互关系,指出产业集群中的核心组织类型是应对需求冲击的实体企业和虚拟企业,并通过对需求冲击的分析,重新划分了产业集群的类型,提出了产业集群治理机制的新思路,从而解决了经典公司治理理论对于产业集群治理研究的适用性问题.     

区域金融生态系统基本性状模型研究

金融生态环境概念是我国金融学术界的首创。金融生态环境作为一个全新的理论范畴,其区域空间属性还是一个探索性的初创领域。本文以科学发展观作为指导原则,通过采用状态空间系统分析方法,把区域生态系统的基本特征表达为一个集合即开放性、闭路循环性、根植性和可持续性;并通过采用结构分析方法,揭示了上述基本特征范畴的因果关系路径和测量方程。相对于以往文献的描述性方法而言,本文从提出概念假说到推导立论均体现了一种逻辑论证的科学方法,从而保证了所得出命题及其结论的准确性和可行性。

Reconfiguring the innovation policy portfolios for Taiwan's SIP Mall industry

Since the year 2000, silicon intellectual property (SIP), which can minimize the gap in ‘design productivity’ that exists with systems-on-chip (SOC), has become one of the most important factors in the development of integrated circuit (IC) products in the SOC era. Although SIP is very important for IC industry development, complicated business, technical as well as legal issues inside SIP transactions have hindered successful transactions and the integration of SIPs into SOCs. Thus, web-based SIP e-Commerce mechanisms, called SIP Malls, have emerged, aiming to resolve complex SIP issues. To maintain its leading position and competitiveness in the World's IC industry, as well as the value added by SOC products in Taiwanese IC firms, the Taiwanese government has developed SIP Malls, using innovation policy tools. However, the Taiwanese SIP Mall industry remains immature. No existing Taiwanese SIP Malls generate a profit or account for a significant share of worldwide SIP transactions. This research will develop an analytical framework for defining an innovation policy portfolio that aims to develop Taiwan's SIP Mall industry, so that it will enhance the value added of SIP Malls and, thus, the nation's competitiveness in the SIP and IC industries, something which already has become one of the Taiwanese government's major concerns. The industry innovation requirements (IIRs) are summarized using the Delphi method. Meanwhile, the major IIRs identified by Decision Making Trial and Evaluation Laboratory (DEMATEL) are introduced. After the IIRs are derived, the relationships between the IIRs and innovation policy tools are derived by Grey relational analysis (GRA). Then, the innovation policy tools are clustered, based upon the Grey grades derived by GRA. Finally, reconfigured innovation policy portfolios are presented for the Taiwanese government's policy definition. The results demonstrate that developing an innovative policy portfolio that includes scientific, technical, educational, public enterprise, information, legal and regulatory, financial, and taxation policy tools will be the most necessary step towards developing Taiwan's SIP Mall industry.

“民主化”改革与地区经济表现

依据Polity IV数据库数据,考量20世纪90年代以来“第三波民主化浪潮”中,发展中国家朝着西方价值标准“民主”的重大转变对其经济表现的影响。结果显示,没有证据支持“民主化”改革促进了经济增长;相反,“民主化”改革引致国家治理能力下降,阻碍了经济发展。异质性分析表明,“民主化”改革对经济发展的负效应主要出现在撒哈拉以南非洲地区,且激进的“民主化”改革和被殖民国家的“民主化”改革对经济发展的负面影响更大。鉴于此,西方价值标准的民主既非一国经济发展的充分条件,也非一国经济发展的必要条件,一国选择何种国家治理模式与政治体制应考虑自身的历史、文化、发展阶段等实际国情,而不是盲目推行西式“民主化”。     

The triggers and clustering properties of merger waves

This article studies the triggers and the agglomeration of mergers and acquisitions (M&A) activity within clusters constituted by time, market and industry. Based on almost 500,000 individual transactions, we find that industry factors play a significant role in triggering activity and that M&A agglomerates strongly across related industries. While clustering in time turns out to be insignificant, stock market effects can be either an attracting or a repelling force, depending on the type of deal examined. This supports the view that merger waves are largely driven by industry shocks.
