商用软件价值评估要素研究——基于品牌资产和信息的视角

本文以品牌资产和信息规则为研究视角,从2006年中国ERP市场软件商中随机选取20位进行问卷调研获取数据,对影响商用软件价值评估的具体指标进行Pearson分析,选择影响商用软件评估价值的关键因素,在此基础上对多元回归模型进行分析。实证结果表明,网络效应以及软件的锁定程度、市场行为、品牌忠诚是影响商用软件价值的重要因素,并都对其有着正向的促进作用。     

Accuracy and Reliability Considerations of Option Pricing Algorithms

A wide variety of computational schemes have been proposed for the numerical valuation of various classes of options. Experiences in numerical computation have revealed that the details of the implementation of the auxiliary conditions in the numerical algorithms may have profound effects on numerical accuracy. Difficulties in designing algorithms that deal with the path‐dependent payoffs, monitoring features, etc., have been well reported in the literature. In this article, the theoretical issues on the assessment of numerical schemes with regard to accuracy of approximation of auxiliary conditions, rate of convergence, and oscillation phenomena are reviewed. In particular, the oscillation phenomena in bond‐price calculations and the intricacies in implementing the auxiliary conditions in barrier options, proportional step options, and lookback options are discussed. With different types of options and modes of monitoring (continuous or discrete), the optimal method of placing the lattice nodes with reference to the boundary (absorbing or reflecting) are examined in order to achieve linear temporal rate of convergence. © 2001 John Wiley & Sons, Inc.

山水城市——知识经济时代（高科技时代）的城市建设模式

首先 ,在这里我要衷心感谢“广州山水城市建设论坛”的发起者、支持者和组织者。是你们 ,使我们有这样好的机会 ,在广州聚济一堂 ,研讨如何联系广州城市建设实践 ,实现山水城市科学构想的问题。对广州我是很有感情的。因为 ,自新中国成立开始 ,五十多年来广州一直是站在改革、开放、发展的前沿 ,有许多值得我们学习、借鉴和思考的创新之举。特别是最近 ,当我听到林树森市长宣布 ,广州将“启动山水城市建设” ,并且计划达到“三年中见成效”的消息 ,我又看到李卓彬副市长提出的全新的“广州概念”后 ,我对广州的美好未来更加充满信心。科学在…     

中国医疗卫生事业效益分析之系列研究——2005-2009年中国非营利与营利医疗卫生效益分析

研究2005-2009年全国非营利与营利医疗卫生的发展,中国医疗卫生事业以非营利性为主。医院占据主要床位数。营利医疗机构运用外部资产能力强,非营利机构长期偿债能力强。营利医疗机构有效控制成本费用,就诊方便,住院便捷,以优质医疗服务不断取得社会效益。两类机构还有很大利用资源的空间和提高管理水平。     

A monthly econometric model of the transmission of the Great Depression between the principal industrial economies

This article describes and estimates, with monthly data, a model of the economic interactions between the United States, the United Kingdom, France and Germany over the years 1927–1936. Despite the radically different economic environment, the model shows broadly similar qualitative and dynamic responses to policy instruments and other changes to those of multi-country models estimated on more recent data. The model is simulated to assess the causes of the Great Depression and the particular contribution of European and American policies to the slump. Optimum strategic policy equilibria are then computed. They point to the mismanagement of the US economy as the principal cause of the depression, although French and German policies were also harmful. British policymakers performed rather well, but their economy suffered because of the other countries’ policy errors.

印度对外战略的变化及原因探析

在过去十几年间,印度的对外战略发生了根本性的变革。这既是国际政治、经济环境变化的结果,也反映印度对国家目标、发展重心和思维模式的重新设定。目前来看,印度的对外新战略取得的效果较好。但是,随着印度作为发展中大国的崛起,其在世界上的影响力逐渐增强,印度的对外新战略需要接受的挑战也是不可避免的。
