This paper studied the coordination degree between water environment and social economy in the Yellow River basin from multiple logical and spatial dimensions. Based on the analysis of the interaction between water environment and social economy, the water environment index system of the Yellow River basin was constructed from three logical dimensions of water resources, water pollution and water governance. The coupling coordination model was used to measure the overall coordination degree between water environment and social economy in the Yellow River basin. From the three spatial dimensions of the upper, middle and lower reaches of the Yellow River basin, seven urban agglomerations along the Yellow River and 61 cities, and three logical dimensions of water resources, water pollution and water governance, this paper used Deng’s correlation degree method to measure the correlation level between water environment and social economy and explore its causes. The results show that the overall coordination degree between water environment and social economy in the Yellow River basin is low but increasing. From 2009 to 2018, the correlation degree between the three logical dimensions of water environment and social economy fluctuated between 0.7-0.8 and the spatial differentiation is not obvious. From 2009 to 2018, the correlation degree between water environment and social economy in the middle of the Yellow River basin has been increased, while the correlation degree between water environment and social economy in the upper and lower reaches of the Yellow River basin has been decreased. Taiyuan urban agglomeration shows an increasing trend and Ningxia urban agglomeration along the Yellow River decreases slightly. Among the 61 cities, it needs to focus on the cities of Longnan, Linfen and Baoji that have high correlation between water resources and social economy, the cities of Guyuan, Jincheng and Longnan that have high correlation between water pollution and social economy and the cities of Linfen, Qingyang and Bayannur that have low correlation between water management and social economy.
