Regional Economic Types and Spatial Differentiation of Small Towns in Peri-urban Beijing
用纳尔逊法和区位商法对北京183个小城镇分类，识别出4种经济类型，并用ArcGIS分析其空间分布格局，为小城镇分类规划提供依据。
This paper tries to study on the regional economic types and development dynamics of small towns in peri-urban Beijing by applying the classification methods developed by Nelson method and Location Quotient method into 183 small towns in Beijing. Based on the classification by virtue of the proportion of production value and employment structure of 3 economic sectors,4 types of small towns are thus identified. With helps of the ArcGIS spatial analysis function,the spatial distribution pattern of 4 types of small towns with their evolution trend is analyzed. The results indicate that 4 types of small towns have obvious core-periphery spatial structure but with different function orientation and evolution mechanism. Based on this,the different development strategies for each type of small towns are summarized in order to provide a scientific basis for the classification planning of small towns.
