ABSTRACT
The rapid proliferation of education hubs throughout Asia underscores the need for a robust analytical framework to evaluate their long-term sustainability and competitiveness. This study addresses this gap by proposing a novel Dual-Diamond model, which integrates Porter’s Theory of Competitive Advantage with a Context-Input-Process-Output (CIPO) framework to assess the Sustainable Competitiveness of Education Hubs (SCEH). Employing a mixed-methods approach that combines expert consultation and the Analytic Hierarchy Process (AHP), a quantifiable Education Hub Sustainable Competitiveness Index (EHSCI) was developed, comprising 28 indicators across four dimensions. Application of Grey Relational Analysis (GRA) to data from 12 Asian education hub countries reveals a distinct core-periphery spatial pattern. Furthermore, the analysis identifies two systemic configurations—termed ‘regular’ and ‘irregular’ diamond systems—which reflect contrasting strategies for sustaining competitiveness, characterized respectively by balanced synergistic development or concentrated strategic strengths. The research provides both a theoretically grounded model and a practical diagnostic tool for policymakers, offering evidence-based recommendations to enhance hub sustainability through targeted interventions.
