Yet most digital development strategies fail to adequately address investment needs, and those that do often focus exclusively on investment in infrastructure (broadband coverage), with very few touching on the potential role of foreign investment or IPAs. A comprehensive digital development strategy should cover investment in infrastructure, in digital firms and in the digitalization of firms across all industries. Individual internet adoption levels vary significantly across regions, with the share of people using the internet in developing economies at less than half that of developed economies, and the share in Africa at half the average of developing economies (figure IV.16). The adoption of broadband and usage of key tools such as email and websites among firms are also lagging in developing countries.
