This paper discusses Kolmogorov entropy, established to solved the classic problem of the ergodic theory, and topology entropy, advanced to study the topological dynamical system.

According to the Logistic Equation and the impact of stochastic factors, a stochastic nonlinear dynamical model had been presenred. The max Lyapunov exponent was calculated by Oseledec multiplicative ergodic theory, the local stability conditions had been obtained; the global stability conditions had also been obtained by judging the modality of the singular boundary; the stochastic Hopf bifurcation was analyzed using the invariant measure of stable probability density, and the condition of stochastic Hopf bifurcation had been discussed. The key parameter impacting the urban domestic water consumption had been found by numerical emulation.

根据Logistic阻滞增长模型原理，考虑到诸多随机因素的影响，本文建立了一个城市生活用水量的随机非线性模型，运用Oseledec乘性遍历定理计算了模型的最大Lyapunov指数，得到了局部稳定性的条件；通过对扩散边界性态的分析，得到了全局稳定性的条件；通过分析系统平稳状态概率密度的不变测度，得到了模型随机Hopf分岔的条件，结合实际进行了数值仿真，得到了影响用水量的关键参数。

Thirdly, as the result of this research, the author points out that the following competitive and dynamical evolving network should be the target of Chinese IOS: 1 The network is dominated by oligopoly; 2 Large, medium and small-sized enterprises co-exist in the network; 3 This network structure is realized through market adjusting, and it should be the result of autonomous evolution of IOS; 4 As to the realization of this network structure, government only is an exogenous variable and its function is to create the external condition to promote the evolution of IOS.

所以论文提出了我国产业组织结构演进的目标状态应该是"寡头主导，大、中、小共生"的竞争动态演进型产业组织结构，同时强调这种产业组织结构的实现应该是在市场机制的调节下、在产业组织结构的自发演进中实现，政府的作用空间仅仅是为其实现创造外部条件，不可人为安排一种市场结构。
