The analysis in this chapter is grounded in socio-technical systems theory and platform governance scholarship, which emphasize how technological infrastructures and institutional frameworks co-evolve to shape digital ecosystems. Applying these perspectives to ASEAN underscores that cybersecurity and data governance are not isolated technical issues but integrated enablers of regional trade resilience. This theoretical lens situates the chapter’s contributions within a broader academic context while clarifying their practical relevance to ASEAN’s digital integration agenda.
