This document summarizes a study that examined factors affecting foreign direct investment (FDI) flows to Ethiopia from 1990 to 2011. The study used a multiple regression model to analyze the relationship between FDI inflows as a percentage of GDP (the dependent variable) and five independent variables: market size, trade openness, inflation rate, infrastructure, and human capital. Time series data from 1990 to 2011 on these variables was obtained from the World Bank and analyzed. The findings showed that trade openness and inflation rate had a significant impact on FDI flows to Ethiopia, while no clear relationship was found for market size, infrastructure, and human capital.
