Foreign direct investment (FDI) refers to direct investment into production in another country. There are three main types of FDI: horizontal, vertical, and platform. FDI can occur through automatic or government routes in India. FDI in retail is permitted up to 49% for single brand and up to 51% for multi-brand under government route. FDI in pharmaceuticals is permitted up to 100% under automatic route. While FDI provides benefits like jobs, technology, and access to markets, it also poses risks such as increased competition and dependence. Overall, the benefits of FDI for India outweigh the disadvantages.
