The Influencing Factors of the Functional Division of Beijing-Tianjin-Hebei Urban Agglomerations Based on the Panel Data Model

The article proposes that the main factors affecting the functional division of urban agglomerations are the degree of urban development, industrial structure, traffic conditions, informatization level, marketization level and government's macro-control efforts. Taking Beijing-Tianjin-Hebei Urban Agglomeration as an example, this paper defines the spatial scope of the urban agglomeration, measures the functional division of the urban agglomeration, and empirically analyzes the panel data model from 2003 to 2017, and draws the following conclusions: (1) The significant factors affecting the functional division of the urban agglomeration are industrial structure, informatization level and the government's macro-control efforts. (2) The significant factors that influence the central urban group (Beijing and Tianjin) to play the productive service function are the degree of urban development, industrial structure and informatization level. (3) The significant factors that influence the marginal urban group (the cities in Hebei) to play the production and manufacturing function are the degree of urban development, informatization level, marketization level and government's macro-control efforts.
