Abstract: Family farms are gradually experiencing "non grain oriented" behavior driven by economic benefits. Based on this, this paper used distributed cognition as the theoretical foundation and constructs a concentric circle model and hypothesis model to analyze the influencing factors of family farm grain planting willingness from the perspective of food security bottom line. To ensure the influencing factors of family farm grain planting willingness, a survey was conducted on family farms in a certain region. After investigation, it was found that regional characteristics Local culture has a positive impact on willingness to grow grain, while asset level and individual characteristics have a significant negative impact on willingness to grow grain. To enhance willingness to grow grain from the perspective of food security, guidance should be strengthened and people’s cognition should be optimized.
