Abstract: Against the backdrop of Chinese residents' shifting food consumption patterns toward diversity, nutrition, and health, practicing the "Greater Food Approach" and establishing a diversified food supply system have become crucial strategies for ensuring national food security. As the main body of terrestrial ecosystems, forests abound with rich food resources and possess significant potential for development. This paper systematically elucidates the internal logic behind the development of the forest-sourced food industry from four dimensions: resource endowment, market demand, technological innovation, and policy mix. It points out that the industry still faces prominent challenges such as weak infrastructure, insufficient improved varieties, short industrial chains, and inadequate supportive policies. To address these issues, policy recommendations are proposed, including optimizing institutional mechanisms, strengthening technological research, improving policy support, and establishing high-quality demonstration bases. These measures aim to provide viable pathways for overcoming development bottlenecks, promoting the high-quality growth of the forest-sourced food industry, and strengthening the foundation of national food security.
