By using the super efficient SBM model,the land use efficiency and ecological welfare performance of the Beijing-Tianjin-Hebei Urban Agglomeration from 1999 to 2020 were calculated.The coupling coordination model was used to analyze the spatiotemporal evolution of the coupling coordination degree between the two.The di-rection,degree,and spatiotemporal changes of the influencing factors were analyzed using geographic detectors and geographically and temporally weighted regression models.The results indicate that:(1)The land use efficiency,ecological welfare performance,and the development degree,coupling degree,and coupling coordination degree of the two systems in the Beijing-Tianjin-Hebei Urban Agglomeration show a"first decrease and then increase"trend,but overall,they show a downward trend.(2)From 1999 to 2020,the coupling coordination degree of the Beijing-Tianjin-Hebei Urban Agglomeration shows a spatial distribution pattern of NE-SW direction,and the direction of the elliptical center of gravity movement was the same.The coupling coordination scheduling of cities in northern part of Beijing-Tianjin-Hebei showed significant changes.(3)Among the coupling coordination influencing factors,the e-conomic level regression coefficient is the largest.The explanatory power of the interaction of influencing factors is greater than the sum of explanatory power when they act alone,showing a non-linear enhancement.
