Reverse innovation is a new phenomenon where innovations are first adapted in poor, emerging countries and then diffuse to rich countries. The paper examines this phenomenon across four research areas: 1) the types of innovations emerging from developing countries and why they may spread globally, 2) how internationalization processes are changing, 3) how multinational enterprise strategies and management must adapt, and 4) the effects on foreign direct investment spillovers. The rise of emerging markets is challenging traditional views of innovation originating solely in wealthy nations.
