Study on the Intercity Highway Freight Network in Beijing-Tianjin-Hebei Region

The study of urban and regional networks in the context of flow space is the research frontier and hotspot of urban geography at home and abroad. Foreign studies mostly use information flow and air flow as the main means of studying urban and regional networks. It is of great theoretical and practical significance to explore the study of urban and regional networks that are in line with China's economic and social development. This paper uses the measured data of Beijing-Tianjin-Hebei highway freight to fit the Beijing-Tianjin-Hebei highway freight network, and uses social network analysis method to analyze the highway freight network structure in Beijing-Tianjin-Hebei region; and uses the coupled coordination model to analyze the relationship between highway freight and industrial structure. Research shows: ➀ The main highway freight contact directions of Beijing-Tianjin-Hebei are Beijing and Tangshan. ➁ The vertical grade of highway freight flow in Beijing-Tianjin-Hebei is dominant, and geographical contact group is remarkable. ➂ The network of Beijing-Tianjin-Hebei Highway freight flow tends to industrial system.
