This article reviews The Handbook of Innovation Ecosystems , detailing its "four-domain convergence framework" . It argues that successful ecosystems are not accidental but require the deliberate, long-term integration of Placemaking, Economics, Business, and Governance . It provides a practical guide for policymakers and practitioners to move beyond rhetoric and build durable, inclusive innovation capacity .

Cities should treat innovation district development as a complex system requiring integration across multiple domains and timeframes.
