This paper is mainly the dynamic input-output model that the time lag is one, which is base on the above models. After studying, we consider stochastic factor step by step in it, namely when consumption coefficient matrix is stochastic (when investment matrix is stochastic, it is almost same. So we dont research it), and they are both stochastic, then we research the stable increase solution. We utilize the means of the modern stochastic analysis and Markov process, that the stochastic dynamic input-output model don not exist the stable solution is proved. Namely, economic system must is adjusted constantly. The probability that the collapse time of the economic system is o is one.

本文对在上述基础上构造的一类时滞为1的动态投入产出模型，进行了深入研究，将随机因素逐步考虑进去，即对投入产出消耗系数矩阵为随机的情况(投资系数矩阵为随机的情况与投入产出消耗系数矩阵为随机的情况大致相同，这里就不再证明)，以及二者同时为随机矩阵时所得到的动态投入产出模型的稳定增长解问题，利用现代概率分析及马氏过程的工具，证明了不存在随机动态投入产出模型的稳定增长解；即投入产出模型反映的经济系统必须经常进行调整，其崩溃时间为无穷大的概率为零。

By employing the local Lipschitz condition and Picard sequence, the local existence-uniqueness of solutions of stochastic functional differential equations of Ito-type is firstly obtained. Furthermore, a continuation theorem for stochastic functional differential equations of Ito-type is given by using stochastic analysis technique and the quasi-boundedness condition. Finally, by establishing some delay differential inequalities and using properties of H_m-functions, a stochastic version of Wintner theorem and the global existence-uniqueness of solutions of stochastic functional differential equations of Ito-type are given. The results generalize the earlier publications.

首先，利用局部Lipschitz条件和Picard序列，获得了伊藤随机泛函微分方程解的局部存在唯一性；其次，利用随机分析技巧和拟有界条件，建立了伊藤随机泛函微分方程解的延拓定理；最后，通过建立一些时滞微分不等式和利用H_m-函数的特性，得到了Wintner定理的随机版本和伊藤随机泛函微分方程解的全局存在唯一性，推广了已有的一些结果。

与stochastic相关的网络解释 [注：此内容来源于网络，仅供参考]

stochastic：随机的

随机(random)过程是指偶然的或随机的(stochastic)过程. 在产生具有给定长度的比特串时,它主要得出随机的、完全不可压缩的比特串;有时得出包含一定的规律性,因而具有一定程度的可压缩性的比特串;极少数情况下能够得到非常规则的、具有很大可压缩性的比特串,

stochastic：随机指标

在周五,随机指标(Stochastic)也稍微下跌. 不过,因为它还处于70%水平之上,所以综指短期还是持续保持牛市走势. 要是随机指标跌破70%的话,它就发出短期卖出的第一个警告讯号,不过这讯号得要在随机指标跌破50%时才可以确认.

stochastic：随机

另外有一种系统曾经让决定论的科学家束手无策的,是行为毫无规律的动态系统,我们称之为随机(stochastic)系统. 赌场裡的轮盘系统或是地震的发生机制都被视为随机系统. 对於这类动态系统,我们无法找到一个决定论的模型去预测它的行为.

stochastic：随机指数

如果你想玩day-trade,应该看五分钟走势图协助,例如随机指数(Stochastic)、保历加通道(Bollinger Band)、简单移动平均指数及加权移动平均数(EMA)、了解买卖周期(buy-sell cycles).
