| 10. | In the second section of chapter 2 , the fact that the essential interest rates of all nodes differ from each other is discussed , a non - homogeneous differential equation model of interest rate - amount of circulating fund is established , and it is proved that the sum of the weighted interest rates of each node in the financial network still remains a constant and that the difference of the instant interest rates between two nodes will finally approach the difference between their basic interest rates . in the third section of chapter 2 , the differential equation model of interest rate - amount of circulating fund in an open system is studied , the laws of changes of interest rate are taken into account when fund is injected into or withdrawn from the node or when fund is injected into the network or withdrawn from the network , and the stability of equilibrium solution is proved based upon lyapunov stability theory . in the last , the equation model of interest rate - amount of circulating fund in the financial network with time delay is studied , and a necessary and sufficient condition for the existence of periodic solution is obtained to the interest rate - amount of circulating fund equation with delay 本文第二章首先建立了封闭系统的利率?流通量微分方程模型,证明了各结点利率加权和为常数即金融市场利率均衡原理,以及各结点利率极限为整个网络平均利率;其次在各结点基本利率不相同的情况下,建立了非齐次利率?流通量微分方程模型,证明了金融网络各结点利率加权和仍是一个常数,并证明了各结点两两之间的即时利率之差最终将稳定地趋于其基本利率差;此外,还研究了开放金融网络利率?流通量方程模型,考虑了结点自身追加资金和提走资金的情形以及网络外部注入资金和向外部转移资金情形下的利率变化规律,用lyapunov稳定性理论证明了模型均衡解的稳定性;最后,还研究了具有时滞的金融网络利率?流通量方程模型,并给出了具有时滞金融网络的利率流通量方程具有周期解的充要条件。 |
