Abstract: The coupling coordination degree is an important index to measure the coordinated development level of industry, transportation and environment. This paper uses the coupling coordination model to conduct an empirical study on the cooperative development relationship of industry, transportation and environment in Beijing-Tianjin-Hebei from 2006 to 2016. It is found that the industry, transportation and environmental of Beijing-Tianjin-Hebei region show a trend of fluctuation and rise, and the three are closely related. The coupling coordination degree of "industry-transportation-environment" system in Beijing-Tianjin-Hebei region decreases slightly in some years, but the overall performance is stable growth. The regions with good coupling coordination degree are distributed in the "southeast" line of Beijing. There is no spatial correlation in the coordinated development of system coupling. In addition, by comparing the coupling coordination level of the three major urban agglomerations in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta, it is found that the three major urban agglomerations show similar development trends and spatial distribution characteristics during the research period, the coupling coordination level of the three major urban agglomeration systems is relatively low, and they are all in the stage of barely coordinated development.
