改革开放以来我国商品流通速度波动的实证研究

商品流通速度是衡量流通部门运行质量的一个重要指标.商品流通速度的快慢不仅关系到经济的总体运行状况,更反映了流通部门资金的利用效率.改革开放以来,我国的商品流通速度得到了持续提高,但商品流通速度的宏观模型却反映出商业规模因素是促使其提高的主要因素.而通过商品流通速度与流通资本利用效率分析发现流通部门的资金利用效率则呈现下降趋势.     

绿色壁垒的壳层结构及其效应研究

绿色壁垒具有全球性条款、区域性协定和国别性措施三个壳层结构,壳层结构之间和壳层结构内部存在着梯度变化关系,且由外向内依次递增,突破难度依次增大.作为发展中国家的我国产品出口必须有针对性地对这种绿色壁垒的壳层结构实施逐层突破,建立相应的危机预警和防范体系,才能增强其出口产品基于环境的国际竞争力.     

服务业与综合国力的关系

当今世界已经进入服务经济时代.服务经济时代的服务业就是现代服务业.现代服务业的基本特征是,先进的科学技术,丰富的文化内涵,合理的产业结构.在国民经济中,它具有经济增长力、生产推动力、产业协调力、劳动吸纳力、社会凝聚力、形象感召力、设施承载力、安全保障力,极大地提高综合国力.     

再论中国金融体系的脆弱性

本文的目的就是通过验证我国金融体系在不完全市场的制约条件下,能否发挥"价值创造、价格发现、风险分散、流动性供给、信息生产和公司治理"这六大基本功能,以及通过进一步检验货币政策的有效性,来揭示当今中国金融体系脆弱性的表现及其症结所在.论文通过分析发现,目前影响我国金融体系"健全性"的两大基本要素是房地产价格和流动性,它们直接左右银行的信贷行为;相反,利差幅度和基础货币的调控却没有显著的制约效果.所有这些特征都恰恰反映了我国金融体系的基本功能至今为止还没得到有效的发挥.     

Program Evaluation and Review Technique (PERT) in Construction Schedule Risk Assessment

Construction project scheduling is one of the most critical factors for project success measurement.Not only for the project planning but for construction process management,the scheduling is the basic tool for communication between the owner and the project manager.By developing the schedule before the project starts,the owner knows in advance that the expected timeline of the project.By preparing construction process scheduling,the owner and general contractor can better manage the subcontractors,sub-trades progress,materials storage and deliveries,labors schedule and equipment set up which will eventually save time,money and hassle.Basically,Critical Path Method(CPM) is commonly used in the construction industry.CPM is a deterministic method that assumes that through the network,there is at least one path that determines the project duration and that the path is the critical path.CPM does not consider the uncertainty in the activities;rather it assumes that each activity can be finished in the given situation.Program Evaluation and Review Technique(PERT) is a stochastic technique which is based on the assumption that the duration of a single activity can be described by a probability density function.PERT takes into account the uncertainty during the construction process and has been created out of the need to plan,schedule and control complex projects with many uncertainties.The PERT approach is stated in some books and papers,but there is no deep investigation on the application in the schedule risk assessment.This paper investigates the PERT work process and takes a valuable try on the construction schedule risk assessment by using case studies.The utilization in the estimate the construction liquidated damage with the uncertainties is performed,which also can be used in the insurance company to calculate the insurance premium.     

国内金融风险预警系统研究综述及综合经营下的EWS框架构建

文章通过对1997年以来国内在金融风险预警系统研究文献的梳理和评价,以研究我国金融风险预警系统研究领域的弱势及空白领域。在借鉴国内外成熟和最新的理论成果及预警方法实践的基础上,结合当前我国金融业综合经营趋势及该趋势下风险来源、传染路径的特殊性,探讨了适用于金融综合经营趋势下的风险预警框架的构建。
