金融股票市場是個極度複雜的系統
不但有許多外力干擾因素 還有內線 以及各種政府的政策措施等等
不過如果只是用一些比較簡化的模型
其實金融市場可以用幾組簡單的非線性方程式去描述它的動力行為
在非線性力學領域
有一種非線性或是混沌的控制方法
ex: OGY方法(Ott-Grebogi-York)或Pyragas method
OGY可以應用在心臟不規則跳動的治療方法上
透過一些回饋控制的調節
讓可能出現混亂的心跳重新變得正常
請問各位知道
目前台灣或是其他國家
政府或是經濟部門 已經有在透過這樣的非線性調控的方式
來手動穩定金融市場的秩序嗎?
還是這只是一個學術上的概念
要實際應用在真實市場或經濟環境
可能不太容易也不太有成效呢??
因為那組非線性方程式要非常精準 才有可能讓調節的效果出現
不然可能越調整越差?
有人知道這方面的資訊嗎?
能否分享一下?
P.S.我剛看wiki,他們說非線性調控其實不需要很精準知道方程式的實際長相。
只要在收集Poincare的面上的數據就能玩調控了。
