The spatial differences of economic strength of 109 counties along the Lower Yellow River in 2009 have been analyzed by weighted principal component analysis, trend analysis tools and Moran’s I index of GIS. On this basis, the classification of economic strength is realized by the SOFM neural network model in MATLAB 7.0. The study shows that, the spatial concentration of the county economy is very significant as was indicated by Moran scatter plot. The level of economic strength of 109 counties can be divided into five categories with the principal component scores as the input of the SOFM network.
