国际水电工程总承包商设计方合作联盟机理

基于文献调研,构建了国际水电EPC(Engineering-Procurement-Construction)项目总承包商-设计方合作联盟模型.通过问卷调研、访谈和案例收集,运用相关分析、聚类分析、典型分析等方法研究了合作联盟各要素间的关系,验证了合作联盟模型的合理性,揭示了合作联盟作用机理.得出的主要结论有:①共同投标是总承包商与设计方进行深层次合作的基础.成功中标后,双方公平分配利益与风险,以增进信任.以信任为基础,促进双方间的有效沟通.有效沟通使双方之间的信息高效流通,可及时解决项目实施中遇到的问题.②激励是总承包商-设计方合作联盟的重要支撑,可促进双方伙伴关系的发展;同时,良好的伙伴关系有助于落实激励措施.总承包商与设计方在项目实施过程中建立的合作伙伴关系为双方长期战略合作奠定良好的基础.项目顺利实施后,激励使总承包商与设计方共享项目收益,有助于二者建立战略联盟,共同投标未来的EPC项目,拓展更大的国际市场.     

Managing redistribution of toll revenue with user heterogeneity

With the explicit consideration of user heterogeneity, i.e., each user has a different value of time （VOT）, this paper examines the system efficiency and social equity of toll revenue redistribution in a bi-mode transportation system. Three schemes of distributing the road toll revenue are proposed, which respectively consider efficiency, equity, as well as efficiency and equity together. With mild assumptions, we prove that the number of auto-motorists decreases and the total social cost increases with transit subsidy share when only marginal operating cost of the transit is covered by its fare. However, when average fixed cost of the transit is further covered, the total social cost is a ＂U＂ shape curve against the transit subsidy share. Numerical results show that the well designed toll revenue redistribution schemes can make the system more equitable while keeping high efficiency. With the increase of user heterogeneity, the Gini coefficient becomes larger while the total social cost goes down.

THE SYMMETRY GROUPS OF NONLINEARITY CRITERIA

It is already known that there are several nonlinearity criteria such as algebraic degree, nonlinearity,distance to linear structures, correlation immune, propagationcriterion, differential uniformity,which are used to check whether a cryptographic functionis weak or not. In this paper we will discuss these criteria from a valuation point of view,and consider the largest transformation group which leave a criterion invariant, which isnamed its symmetry group. It can serve as a way of comparing the stability of nonlinearitycriteria under the action of invertible transformations.     

An Empirical Research on the Model of the Right in Additional Allocation of Stocks

How to define the value of the Right in Additional Al location of Stocks (RAAS) acts an important role in stock markets whether or not the shareholders execute the right. Moreover, the valuation defining of RAAS an d the exercise price (K) are mutual cause and effect. Based on some literatures on this subject, this paper presents a model valuing the RAAS per-share. With t he opening information in ShenZheng Stock Markets, we make a simulation on the R AAS‘s value of shenwuye, which is a shareholding corp...     

从巴县档案看传统合伙制的特征

中国传统合伙组织虽然有多种合作方式，但基本上以人合为前提，契约对维系合秋具有重要意义，股份均一的原则在合秋制中基本得到了体现，合伙组织的所有权与经营权不发生分离，合伙人对债务实行共同清偿，但彼此之间一般不发生连带行为。同西方制相比较，中国传统合伙制比较接近于近代早期的私人合伙公司。
