The empirical research on relationship between the industrial structure and urban evolution of the region of Beijing-Tianjin-Hebei

The region of Beijing-Tianjin-Hebei dominates the economic development in China's northern region,and its coordination between industrial structure and urban evolution is great significant to regional economy. Firstly, based on the concept of the urban evolution, the article proposes comprehensive index system of the industrial structure and urban evolution. Then, using the SAS software, with the method of factor analysis and correlation analysis, processing the 21 years' data of Beijing-Tianjin-Hebei, the paper does empirical research on the relationship between the industrial structure and urban evolution, and assessed the interaction between the tertiary industries and urban evolution. The result shows that, the first industry plays a dynamic function, but its own development is limited, cannot be sustained upgrade; the secondary industry does not form a sound development mechanism and role in promoting the urban evolution decline; the third industry promotes the urban evolution, but there is the phenomenon of virtual sophistication.
