Considerable progress has been made in the research and construction of regional public brands for agricultural products. After experiencing several models such as the three-tier structure of "city, county, and enterprise", a brand structure based on the four tiers of "city, county, town, and enterprise" has emerged, and it has further evolved into a holistic regional public brand model that encompasses multiple industrial elements such as agriculture, light industry, cultural tourism, health care, and cultural creativity. However, during the development process, there are still problems such as inter-level and intra-level resource incoordination among brands at all levels, as well as the absence of digital links for brand communication. Through the review of models, this paper explored how to deepen the collaboration among various subject levels of holistic regional public brands for agricultural products under the background of common prosperity, create new-quality productive forces, drive common prosperity in the regions, and achieve high-quality development.
