基于因子分析的我国区域研发能力差异比较研究

由于经济、科技发展水平不同,我国各地区在研发能力上存在较大的差异.为了对我国区域研发能力差异进行定量化分析,本文引入了研发投入强度、研发经费相对规模、研发人员相对规模、主要检索工具收录论文相对数量、授权专利相对数量、技术市场相对规模、新产品产值相对规模等指标,根据(2006年中国科技统计年鉴>提供的数据,通过因子分析,对我国各省区研发能力差异进行比较评价.     

中国金融业分业经营与混业经营研究

实践表明，混业经营有助于增强金融机构的国际竞争力，促进一国经济的发展，目前已成为全球金融业发展的趋势。就我国而言，从长远的角度来看，混业经营是金融业的必然选择，但短期内尚不具备过渡的条件。由于我国已加入WTO，所以目前应抓住机遇，采取相应的对策，为将来混业经营作好准备。     

Pricing options using implied trees: Evidence from FTSE‐100 options

Previously, few, if any, comparative tests of performance of Jackwerth's ( 1997 ) generalized binomial tree (GBT) and Derman and Kani ( 1994 ) implied volatility tree (IVT) models were done. In this paper, we propose five different weight functions in GBT and test them empirically compared to both the Black‐Scholes model and IVT. We use the daily settlement prices of FTSE‐100 index options from January to November 1999. With both American and European options traded on the FTSE‐100 index, we construct both GBT and IVT from European options and examine their performance in both the hedging of European option and the pricing of its American counterpart. IVT is found to produce least hedging errors and best results for American call options with earlier maturity than the maturity span of the implied trees. GBT appears to produce better results for American ATM put pricing for any maturity, and better in‐sample fit for options with maturity equal to the maturity span of the implied trees. Deltas calculated from IVT are consistently lower (higher) than Black‐Scholes deltas for both European and American calls (puts) in absolute term. The reverse holds true for GBT deltas. These empirical findings about the relative performance of GBT, IVT, and Standard Black‐Scholes models are important to practitioners as they indicate that different methods should be used for different applications, and some cautions should be exercised. © 2002 Wiley Periodicals, Inc.

HEDONIC PRICING MODELS FOR VEHICLE REGISTRATION MARKS

Abstract.  This paper attempts to link Chinese numerology to the determination of vehicle registration mark (VRM) prices in Hong Kong through the hedonic pricing analysis. The values of different patterns of the numbers and Roman alphabet letters are examined. We find that there is a very strong preference for the number '8', that visually appealing patterns add great values to a VRM and that the non-transferable VRMs are more expensive than transferable ones. We also show that their prices move in tandem with the Hang Seng Index. The findings suggest that the government can raise revenue by auctioning off intangible assets containing alphanumerical identification marks.     

“以大代小”火力发电企业的价值评估

在火力发电行业进行“以大代小”技改工程后,为了解决“一厂多制”的问题,需要对完成“以大代小”技改项目后所产生的新发电企业进行价值评估。在评估过程中,应明确价值类型,充分考虑租赁的资产、委托运行维护管理等要素对企业价值的影响。本文对大型火电发电机组的生命周期进行了分析,并在此基础上提出了对“以大代小”新火力发电企业进行收益测算的“三阶段测算模型”。
