Based on both panel data of 31 provincial-level administrative regions in China from 2006 to 2020, and analyzing the comprehensive level of grain storage facility construction in China, this paper studied the spatial and temporal evolution characteristics of the coupling and coordination between grain storage facility construction and economic development, and drew the following conclusions: during the research period, the comprehensive evaluation value of grain storage facility construction in China fluctuated and raised, showing a trend of high in the east and low in the west. The coupling coordination degree between grain storage facility construction and economic development was low, showing an upward- downward-upward trend. The spatial correlation of coupling coordination degree had gradually become significantly increased since 2009, and the degree of spatial agglomeration was high in the north and low in the south. The spatial evolution pattern tended to move to the northeast. According to the research conclusions, it is suggested to improve the coordination and matching degree of grain storage facility construction and economic development in different provinces according to local conditions in the future, which could promote the development of surrounding areas with high coupling coordination degree, and finally realize the coordinated progress of grain storage facility construction and economic development nationwide.
