ABSTRACT 
According to the theory of spatial interaction and model of comprehensive attraction between cities, the spatial development of Beijing, 
the Capital of China, was studied in this paper supported by GIS spatial analysis functions. There are four parts in the article. At first, the 
theory basis and model characteristic was reviewed and discussed. Two important models were quoted to calculate the current attraction 
between cities and development potentiality of Beijing. Then, the method and workflow were put forward which include four steps, such as 
database preparing, spatial analyzing, potentiality calculating, and comprehensive analyzing. Based on the method mentioned above, the 
calculation process was described one by one, such as determining development axes of Beijing, defining model parameters of attraction, 
selecting mass of cities around Beijing, measuring distance between Beijing and other cities, and calculating development potentiality of 
Beijing. Finally, comprehensive analysis was done and some results were put forward. The conclusion is that the future spatial 
development direction of Beijing is southeast axis which facing many cities, such as Tianjin, Langfang, and Huanghua.

city development. The earlier scientist who interested in the radius of city i or the half of the distance between city i and its

2. METHODOLOGY FRAMEWORK 
According to the principle of spatial interaction between cities, the 
demand of spatial development research for Beijing, and the 
natural environment and social economy situation of the region, a 
framework of research method is worked out as shown in Fig. 1 
based on the characteristics of GIS. The framework includes four 
steps: data preparing, spatial analyzing, productivity calculating, 
and comprehensive analyzing. 
Based on the model of W. J. Reilly, P. D. Converse worked out 
another model named “Break Point Model” gravitation (Refers 
with Eq. (2), Converse, 1949).

databases include spatial database (such as administrative 
divisions, topographic contour, transportation system, residential 
distribution, and so on) and attribute database (such as 
population statistical data, staff and workers, gross domestic 
products, and so on). These data are the basis for further 
calculating and analyzing.

between city i and city j. Wj and Wj refer to mass weight factor of On the basis of residential distribution and transportation system, 
city i and city j. Pj and Pj refer to mass of city i and city j. D^ seven possible development axes and their radiation regions
