The Research，using the multidimensional poverty index method，indicates that：1. The generation rate of child multidimensional poverty in the minority-concentrated region is significantly higher than that in the non-minority-concentrated region. Child poverty in the minority-concentrated region is more serious than that in the non-minority-concentrated region in regardless of scope，depth or structure. 2. Children in the minority-concentrated region face seriously deprived of development，education，survival and health opportunities. 3. Depth and severity of all child poverty indicators in the minority-concentrated region are clearly higher than those in the non-minority-concentrated region，with poverty embodied in the deprival of some more fundamental demands.
