Abstract:

：This study described the spatial variation in China spatial explicitly through a series of ellipses according to Krugman's "first and second natural" theory. The ellipse of national geometric profile in China was taken as the original state of spatial variation. The first nature variation could be explained through the ellipse of topographical distribution in China, and the second nature variation was represented by the spatial distribution of population. The results are as followings. 1）The spatial variation is mainly between the eastern and the western area in China. The spatial coverage of topographical distribution ellipse is in the west, and it is much smaller than the equilibrium distribution ellipse which is in accordance with the topographical characteristics that the west is higher than the east in China. The population distribution ellipse is mainly covering the North China Plain and the Middle and Lower Yangtze Valley Plain and its spatial coverage is much smaller. It is proved the spatial variation of the first nature and the spatial agglomeration of the second nature. 2）The spatial variation from the first natural factors is significant in China. 93% of the population distribution ellipse range is located in the southeast of Hu's line, and the main axis is almost parallel to Hu's line. The spatial variation index of population distribution ellipse to the topographical distribution ellipse is 89.55%. 3）For the prefectural-level cities, the population ellipse and GDP ellipse are aggregated in the southeast of Hu's line which is 20% of the mainland area in China. There is the spatial disparity between the population and GDP distribution. In general, the natural endowments between the east and west in China resulted in the unbalanced beginning of regional development. It is shown that the regions in the north of Hu's line, especially in the northwest area, is weak to gathering the population. Meanwhile, spatial differences of the agglomeration which is the inner core of the regional developing momentum present the unbalanced process of regional development. From the perspective of both efficiency and equity, the promotion of Chengdu-Chongqing, Guanzhong and other major economic zones which is with the large population is relatively could stimulate the economic growth in central and western China, and to attract the population concentration in the north part of GDP distribution ellipse could promote the economy development from the south to the north. In addition, Standard deviation ellipse method can not only subtly describe the spatial variation of the different features, but also can quantitatively analyze the extent of spatial variation, and it is proved to be a new method for reference to study the economic spatial variation.
