This brief aims to help design the Indo-Pacific Core and Peripheral Digital Economic Communities, focussing on emerging and ever-changing geopolitics and geoeconomics. The brief discusses the background of the Indo-Pacific Digital Economic Community, the Indo-Pacific International Collaborative Research, the Digital Economic Development, the Core and Peripheral Digital Economic Community, the Megacity System, and the Digital Knowledge-based Economy for enhanced household income generation. It also discusses the approach to transforming an existing community into a digital economic community, the feasibility of changing it within a regional framework of megacity systems and industrial corridors with large-scale industrialisation and heavy investment in infrastructure, the impact of the digital economy on households with the lowest income, roadblocks, essential nature of Indo-Pacific countries, and the differences between Core and Peripheral Smart Economic Communities. The design brief also discusses the vision, goals, and objectives ideal for transforming a community into a digital economic community and the tax and anti-corruption initiatives suitable for digital economic communities. Digital public goods (DPG) are the foundation of any nation’s digital economy, and the digital integration framework made in India, ASEAN, and the Indo-Pacific Economic Framework is essential. The digital economic community is designed to provide enhanced living and a digital economic community with higher income commensurate with a higher standard of living. The training of digital economic communities for developing the Indo-Pacific region, ASEAN Digital Integration Framework, and Indo-Pacific Economic Framework for Prosperity are also discussed.
