Spatial analysis on agglomeration and diffusion of Beijing-Tianjin-Hebei urban agglomerations
The spatial analysis of the agglomeration and diffusion of Beijing-Tianjin-Hebei urban agglomerations can promote the coordinated development of the regional economy in the Beijing-Tianjin-Hebei region. Based on the urbanization level of Beijing-Tianjin-Hebei urban agglomerations in 2020, this paper built a geographically weighted regression (GWR) model and compared it with the ordinary least square (OLS) method to reveal the spatial differentiation of urban land and the influence of different driving factors. The results show that population density and per capita gross domestic product (GDP) play a positive role in promoting the urbanization process, while the distance to the railway and that to the center of the urban agglomeration play a negative role in weakening the urbanization process. At the same time, the GWR model takes into account the heterogeneity of spatial phenomena, and its decomposition into local parameter estimation is superior to the global parameter estimation provided by OLS. The proposed model can deeply reveal the complex relationship between urbanization level and driving factors.
