The digitalization of the grain industry chain plays a significant role in ensuring food security, improving industrial efficiency, and advancing the high-quality development of the grain industry. Survey results from government departments, circulation enterprises, research institutions, and testing organizations indicate that digitalization technologies have been widely applied across various links of the grain industry chain, though the depth of application varies significantly among different links. Digitalization technology equipment primarily consists of domestic brands, with relatively high equipment values. Digitalization technologies can effectively promote grain quality safety and improvement, and demonstrate notable management effectiveness in enhancing management levels, economic benefits, and social benefits. Currently, the digitalization of the grain industry chain faces issues such as insufficient supply in terms of policies, technologies, and investments. It is recommended to provide active policy support in areas such as digital infrastructure construction, financial taxation, pilot demonstrations, and talent cultivation.
