摘要
亚洲金融危机以后,世界各国评估和诊断金融体系稳健程度的实务性研究取得了很大进展,但金融稳定性问题的理论研究仍相对滞后.本文讨论了用生态稳定性思想方法研究金融稳定性问题.文章先比较了金融稳定性的概念和生态学中有关稳定性的概念的异同,把生态稳定性概念移植、引申到金融系统中,建立了金融群落数学模型,给出了金融群落金融稳定的定义,论证了金融种群确定模型和随机模型的稳定性,介绍了金融群落随机模型的稳定性,最后分析了金融群落等级结构的稳定性.
After Asian crisis the empirical research on evaluating the stability of financial system has been made great progress,but its theoretical research has still lagged.This paper uses ecological stability method to study financial stability.Firstly it compares the differences between financial stability and ecological stability.It then transfers ecological stability to financial system and establishes financial population model,discussing the stability of financial population definite model and stochastic model,proposing a definition of financial population stability.Finally,this article analyzes the stability of tier structure of financial population.
