The analysis of economic spatial characteristics of Beijing-Tianjin-Hebei metropolitan region based on GIS

The regional economic disparity is always a research hot spot to domestic and foreign scholars. In this paper, we take the Beijing-Tianjin-Hebei metropolitan region as research object and take the county administrative division as the basic research units. Considering the spatial characteristics, the exploratory spatial data analysis method of GIS is introduced, which includes global spatial autocorrelation and local spatial autocorrelation methods. Through constructing spatial weight matrix and analyzing a series of indexes which contain Moran I index, Moran Scatter Plot and LISA and so on, the economy spatial distribution of Beijing-Tianjin-Hebei metropolitan region over 2001∼2006 is obtained from the spatial interactive angel, and the spatial autocorrelation and spatial heterogeneity among counties are revealed.
