The problem of the research is studying: what are the most important factors effecting the vegetable oil gap in Egypt? The study used time series data during the period (1975-2021), and the results showed that the biggest three crops produced were cotton seed, olives, and groundnuts, according for about 89% of oil crop production during the study period. While olive oil production multiplied one hundred times during the study period, cotton seed production decreased by about 88.6% from 1980 to 2020. The results show that the study variables are significantly affecting the vegetable oil gap in Egypt despite population growth and the world vegetable oil price. Accordingly, the study's findings on economic relationships can consolidate the current research on Egypt's vegetable oil gap. Policymakers and decision-makers can also ascertain the impact of variables influencing the vegetable oil gap.
