Abstract: This article investigates how agricultural R&D investment affects the food self-sufficiency ratio (SSR). Several studies have argued a causal relationship between agricultural R&D investment and food security. However, most of these studies are based on conceptual logic and few studies have conducted an empirical analysis. This study verifies whether agricultural R&D investment affects the food SSR as a representative indicator of food security. A total of 822 data sets of 41 countries have been used in the analysis in this study and include developed and developing country data over the period 1981–2009. Food self-efficiency is used as a dependent variable, and agricultural R&D investment and other variables are used as explanatory variables. The estimation results show that, first, the cereal SSR and income are in an inverted U-shaped relationship. Second, increases in land productivity increase the cereal SSR and, lastly, the cereal SSR ratio and agricultural R&D investment are in a U-shaped relationship.
