Abstract: The coordinated development of water and soil resource matching and grain production is essential to enhance integrated grain production capacity and promote sustainable development in agriculture. Based on the perspective of a water footprint, this article empirically evaluates the coupling coordination relationship between water and soil resource matching and grain production in typical black soil areas in Northeast China using the coupled coordination degree and the obstacle model and further analyzes the obstacle factors that affect the coordination between the two systems. The results indicate that the blue water footprint, green water footprint, and total water footprint of five grain crops are increasing year by year. Soybean has the largest water footprint per unit mass, tubers have the smallest, and rice has the largest water footprint among cereals. The overall matching degree of water and soil resources in the study area is steadily increasing. However, there are significant differences in the water and soil resource matching coefficients between regions, with the highest being observed in Hegang City and the lowest being observed in Jiamusi City. Coupling remains at a high level and coupling coordination shifts from a low–middle–high to a middle–high stage. The correlation between soil and water resource matching and grain production systems is of significant importance. The degree of matching between water and soil resources serves as the primary obstacle affecting the coupling and coordinated development of integrated systems, which fundamentally restricts the sustainable development of regional agriculture.
