Employment Spatial Models and Regionalization of China
中国就业的空间模式及区域划分

The importance associated with employment is especially prominent all over the world especially in China. The population quantity brought huge pressure to the harmonious society of China. This paper records the findings of a survey into the fifth census data of China, and the authors chose 16 indexes in each county, city and urban district based on the GB/T4754-94 industrial classification standards. With the methods of Principal Component Analysis and Hierarchical Cluster Analysis, and visualization technique of ARCGIS,we conclude the employment structure features and spatial distribution of 2343 counties, cities and urban districts in China. The views expressed in this paper are as follows: First, there exist six spatial modelsin Chinese population employment, i.e., serial-concentric circles, discontinuous-concentric circles, jumpable-concentric circles, mixed-concentric circles, multi-cores concentric circles and belt-concentric circles. Second, we find that the population employment along eastern coastal areas of China and the Yangtse River formed a "T-shaped" pattern, and the spatial distribution of China's employment of an evident urban-rural duality with six clusters. In the Eastern cluster and Northern cluster, the population employment centered upon the secondary industry; in the Beijing-Tianjin cluster, the population employment centered upon the tertiary industry; the Middle Western cluster, the population employment centered upon the first industry; as the Eastern cluster and Northern cluster, the population employment of the Xinjiang cluster centered upon the secondary industry.
