The research aimed to study the most important factors affecting the demand for the most important Egyptian agricultural crops, namely citrus, potatoes and onions for the five most important importing countries for these exports, namely Saudi Arabia, Germany, France, Italy and the United Kingdom. In achieving its goal, the research relied on secondary data published from various sources such as the Central Agency for Public Mobilization and Statistics, the Food and Agriculture Organization of the United Nations, and the World Bank. The study also relied on the Simultaneous Equation Model in estimating the factors affecting the demand for the most important Egyptian agricultural exports. The results showed that agricultural exports are the main driver of economic growth, as the average value of agricultural crops exports amounted to about $909.8 million, with an annual growth rate of about 5.59% during the average period (1986-2019). The results also showed that there is a strong direct relationship between the value of exports of citrus, potatoes and onions and the value of Saudi Arabia's GDP, with a value of about 0.92, 0.94, 0.90, respectively, which indicates that the Saudi market is the most important market that requests these crops, as the amount of exports of these crops It increases with the increase in Saudi GDP. The research recommends the necessity of opening new export markets in addition to the current markets and working to improve the quality of these crops according to specifications and working to increase exports to the Saudi market.
