Abstract: Putian loquat, a national geographical indication product with a cultivation history spanning over 800 years, stands at a critical juncture of transitioning from a regional specialty to a national cultural wellness brand. This paper transcends the descriptive paradigm of traditional agricultural product research by introducing cultural semiotics and the modern transformation path of medicinal and edible homology, thereby constructing a dual-drive analytical framework of "cultural capitalization" and "functional value productization." The study reveals the intrinsic mutual construction between these two theories: symbolic consumption theory explains how loquats gain premium value through cultural meaning, yet cultural encoding requires material anchors; the evidence-based science of medicinal and edible homology provides precisely this anchor—layering cultural meaning atop genuine health efficacy to form a value-generating double helix of "health efficacy as the foundation, cultural symbol as the wings." The research first traces the historical and geographical migration of Putian loquat from Bashu to Fujian, then deeply decodes the process by which the loquat has been constructed as a visual, ethical, and aesthetic symbol of the "golden pill" in poetry and painting, elucidating its evolutionary logic from "use value" to "symbolic value." From the dimension of medicinal and edible homology, this paper employs an evidence-based medical perspective to build a bridge between the traditional experiential system of "moistening the lungs in all seasons" and modern pharmacological verification, demonstrating the scientific foundation for its functional food development. On this basis, the paper proposes a practical industrial leapfrogging scheme: targeting the dualistic market structure of North and South China, it designs differentiated strategies of deep cultivation of fresh consumption markets in the South and expansion of wellness markets in the North; constructs a pyramidal variety IP matrix of "treasure-building products, profit-generating products, and traffic-driving products"; and leverages key time nodes such as the Beginning of Summer in 2026 to create an omnichannel communication closed loop featuring "CCTV endorsement + social media seeding." The study aims to provide both theoretical support and practical pathways for transforming Putian loquat's profound cultural heritage and clear health value into core competitiveness.
