Drawing on UNCTAD Entrepreneurship Policy Framework, it touches upon best practices for governments to strengthen entrepreneurship ecosystems, ensuring smaller enterprises and start-ups can fully benefit from the new technological wave while acknowledging risks and challenges. It highlights updated business development services, including AI-focused training offered through, for instance, UNCTADs global Empretec network, designed to equip entrepreneurs for AI adoption. This publication is informed by an extensive literature review and a broad range of stakeholder consultations, including representatives from international organizations, government bodies, business development centres, the private sector, not-for-profit organizations, investors, academia, business and AI specialists, and entrepreneurs.
