Abstract: 【Purpose/significance】Analyzing the current status of food security information services research in our country to provide a reference for the theoretical research and practical development of food security information services.【Method/process】Employing bibliometrics and textual content analysis, the research delves into domestic and international food security intelligence services from three key dimensions: historical, current, and future domains. Its objective is to pinpoint research hotspots and directions within the field, outline deficiencies in China's approach to food security intelligence services, and present prospects for future research endeav⁃ ors.【Result/conclusion】Our country's research on information services related to food security suffers from dispersed themes and in⁃ sufficient coverage, leaving substantial room for expanding research topics. The theoretical exploration of information services regard⁃ ing food security and the processing of multi-source, multi-modal data demand further in-depth study【. Innovation/limitation】Based on theme coupling matching, the study identifies the missing themes in the current research on food security intelligence services in China, and proposes development suggestions for research in three aspects: theoretical construction, theme expansion, and technologi⁃ cal application of food security intelligence services in China.
