Abstract: In this paper we use a new self-organizing data mining method-Fuzzy Rule Induction(FRI), which extracts Fuzzy rules based on GMDH technique from the data autonomously to form the Fuzzy Model described in a more natural language. Some principles and processes of FRI method are developed in this paper. A model case about the economy in SiChuan Province of China is presented to analyzing some critical factors affecting the increase of GDP of SiChuan, while the related suggestions of policy are derived from this foundation. In addition, the comparison between the FRI and the GMDH has showed the advantage of FRI in anglicizing factor.
