In the research to demand of International reserves,first, according to the affective character of demand to transition of International reserves, choosing the decision theory of Markov and dynamic transition equation as basic model, the paper has set up two transition methods--- stationary matrix and dynamic matrix, the later matrix has improved the sensitive reaction to time and velocity. Second, combining with knowledge of linear algebra, the paper has analyzed and testified the positive associated relation between transition matrix elements on main diagonal and the convergent speed of system, and explained why international reserves transition embodies the character under new situation and why the transition process can be accelerated by the strike of international idle money. Third,on the quantitative calculating to elements of transition matrix,referring to multiplication theory and decomposing-composing method of system, the paper has transformed main three-factor deciding confidence of international monetary into detail modulus by comparing analysis measure,now the matrix has been decided.

在国际储备的需求分析研究中，本文首先选择马尔可夫转移方程作为基础模型，根据需求对外汇储备结构的影响特点，提出非定常转移矩阵变换方法，拓展了马尔可夫变换对时间和速度的敏感性；结合线性代数知识，分析证明了定常转移矩阵的主对角线元素值的大小与系统的收敛速度的正向关联关系，并利用结论解释了国际货币新动向下外汇储备转换表现出的趋势特点以及国际游资冲击对国际货币结构变化的加速影响；在转移矩阵元素的量化计算上，本文参考乘数理论和系统分解合成原理，采用对比分析方法把影响国际货币信心的三大要素综合量化为转移偏好系数，然后根据转移偏好系数确定转移矩阵的元素值，其中还分别具体给出了定常转移矩阵和非定常转移矩阵的计算方法及在变换中的使用方法，从而不仅在定量分析上应证了定性分析结论，而且反映了随时间变化的美圆、欧元、日圆的比例结构均衡过程。

论文给出改进的近似方法，即用正态分布近似分销中心提前期内需求的分布，用更符合实际的负二项分布近似零售商提前期内需求分布，从而建立了二级分销系统期望总成本近似模型。

In this paper, the super-network method is used to analyze the operation process of the supply chains and construct a super-network of the supply chains. In order to decompose total demand with given distribution function, customer choice theory is adopted to acquire the demand of each supply chain.

Value is the product of the relationship of demand and supply between subjects and objects Subjects consist of three levels such as human totality,groups subjecting to the human totality,and human individuals Coresponding to it,objects include the outside world with respect to human totality（groups+individuals+the world outside human being）,the outside world with respect to human groups,and the outside world with respect to human individuals Therefore,things possess value,so do human beings Because humans themselves are the unity of subjects and objects,humans have selfvalue The reciprocal function of the factors constituting value decides the production of value,promote the changes of value,which is the basic subject of thelaw of value The three factors which have influence on the changes in value are the demand of subjects.the character of objects.and practice The origin of the conflicts of value concepts lies in the differences and opposites of the living conditions of human subjects The direct originis the differences and opposites of value objects Therefore,in order to gradually eliminate the conflicts of human value concepts,the differences of the living conditions of human subjects must be eliminated thoroughly

价值是主客体之间需要与满足关系的产物。主体有人类整体、人类整体之下的群体以及人类个体三个层次，与之相应，客体也包括与人类整体相对的外部世界（群体+个体+人以外的世界）、与人类群体相对的外部世界以及与人类个体相对的外部世界。因而不仅物具有价值，人亦有价值。由于人自身是主客体的统一，因而人还有自我价值。构成价值的各个要素相互作用决定价值的生成、推动价值的变化，这是价值规律的基本内容。影响价值变化的主要有主体需要、客体属性及实践三个要素。价值观念冲突的最终根源在于人类主体生存条件之差别和对立，直接根源则在于价值客体的差别和对立。因而要逐步消除人类价值观念的冲突就必须从根本上消除人类主体生存条件方面的差别做起。
