The study purpose is to explore the simultaneous relationships between the Growth, income inequality and Poverty (GIP) triangle in Egypt, and the interaction effect of growth and income inequality on Egypt’s poverty level and the effect of both poverty on economic growth and income inequality on economic growth in Egypt .Using the three-stage least squares (3SLS) method to estimate the simultaneous equations on annual data between 1975 and 2019. The results show that economic growth affects poverty indirectly through the income inequality channel, as increasing economic growth leads to an increase in the misdistribution of income, which leads to a decrease in the poverty rate, and that poverty has a direct negative effect on economic growth. In contrast, inequality has a net negative effect on economic growth, as income inequality has a direct negative effect on economic growth, and income inequality has a positive indirect effect via the poverty channel. The current study also found a negative reciprocal relationship between poverty and income inequality in the Egyptian economy.
