Abstract：Based on panel data from 31 provinces in China from 201l to 2023，this research employed the entropy method to measure the level of digital economy development and constructed benchmark regression and mediation models to empirically examine the relationships among the level ofdigital economy development，agricultural technological innovation，land transfer level and food security. The benchmark regression results indicated that， the development of the digital economy had a significantly positive impact on China's food security，a conclusion that remained valid after robustness checks and endogeneity treatments. Mechanism analysis showed that， agricultural technological innovation and land transfer level in agriculture played significant mediating roles in the impact of the digital economy on food security.Further heterogeneity analysis revealed that， the promoting effectof the digital economy on food security varied significantly across regions： it was significantly positive in the eastern and northern regions，while it was not significant in the central， western，andsouthern regions. Based on these findings， suggesting that region-specific digital economy development policies should be formulated to strengthen agricultural technological innovation and land transfer mechanisms， thereby enhancing the positive incentive effect of the digital economy on food security.
