This research statement discusses factors that influence foreign direct investment (FDI) inflows in Middle East and North Africa (MENA) countries compared to European Union countries. It notes that MENA countries have implemented reforms to liberalize economies and encourage FDI, but FDI inflows remain relatively low. A key reason is that MENA countries invest little in science and technology infrastructure and research, and have fewer patents and scientific publications than other regions, limiting their ability to attract and benefit from FDI. Strengthening business linkages between foreign investors and domestic small- and medium-sized enterprises could help transfer technology and skills to upgrade domestic firms in MENA countries.
