Based on the entropy method and the coupling coordination degree model, this paper the coordination degree of economic and water and land resources in Inner Mongolia Autonomous Region was calculated. It is found that the overall economic composite index of each banner county in Inner Mongolia shows an upward trend of varying degrees from 1990 to 2018, but there is spatial imbalance and increasing gap in regional economic development. The natural resources index shows an upward trend, but the increase is small, and the spatial difference of natural resources is relatively large and shows an increasing trend. Since 2005, the coordination degree of Inner Mongolia has shown an N-shape, indicating that the coordination between economic development and water and land resources has a positive trend.
