Spatial Data Mining (SDM) is a set of techniques aimed at extracting the implicit and user interested spatial patterns and rules, the relationships between spatial and non-spatial data from spatial database, as well as other data characters hidden in the database. Furthermore, the spatial data mining and knowledge discovery techniques aim at mining potential useful knowledge they have known nothing from existed database. Therefore, in recent years, the techniques of spatial data mining have been becoming a research hotspot of space information fields, and a great many important results have been achieved. The disparity of regional economy has always been the hot topic in regional economics fields.
