Forecast Analysis for Beijing''''s Industry Structure
北京市三次产业预测分析

Based on the modeling approach, the development characteristic of the Beijing's industry structure has been studied. And a numerical prediction from 2000 to 2005 for the industry structure is presented to demonstrate the structural change trend in Beijing. To analysis the dynamic features of each composition in a pie chart, a non-linear approach for dimensionality deduction and a predictive model are proposed for the compositional data collected according to a serial time sequence.
