摘要
建立证券价格演化的差分动力系统模型,研究投机行为对证券价格演化的影响,发现投机行为本身并不是证券市场的价格波动不稳定的原因,甚至一定情况下可以稳定价格的波动.本研究对于从数理角度客观的理解证券市场的投机行为具有积极作用.
The difference dynamic system in the security market was modeled,and the influence of speculative action on the price of security was analyzed by the model. The speculative action is not the reason of fluctuation of price, which can make the market more stable to a certain degree. The conclusion could play a role in objective view on the speculative action from mathematic perspective.
