区域差异计量方法的缺失与重构

he calculations of regional differences not only depend on the size of attribute value among regions, but also rely on the relative size of areas or volumes which are occupied by this kind of attribute value. Only transform the diffrent size of regions into the same size of normative regions can directly measure the regional diffrences of attribute value, the size of normative region is just equal to the greatest common divisor of various region in areas or volumes. In any non-uniform region, it is hardly to keep statistical data at the same level both in regions of identical size or non-identical size. The statistical data which from these smallest region is the most perfect data in measuring regional difference if and only if large-scale region is divided into the smallest scale and can't be divided continually,and the premise is that the essence of regional attribute must remain consistent. Of course, the size of the smallest region and the statistical accuracy of attribute value all need to make a concrete analysis according to concrete conditions.
