Abstract:Five important elements and multi-index system of the synthesis level for eight provinces in the large-scale development of the western region have been proposed in this paper by using the principal components multi-layer analysis. Two principle components have been found to explain the synthesis level of various provinces. The result of analysis has proved this method is viable to learn economic problems with multi-indexes.
Keywords:principal components multi-layer analysis  synthesis level  compositive function  ratio of variance
