Model Building and Identification System of Chaotic Economic Time Series

Chaotic economic time series are studied by using time series analyzing methods. Some simple theories and methods of building model about chaotic economic time series are introduced in this article. Extracting nonlinear (or chaotic) messages from chaotic time series and identifying system are set forth. In this paper, deciding region of chaotic critical spot on chaotic system is also discussed. Some good results are obtained by testing realistic case and programs calculating.
