Digital Public Infrastructure, Crisis Communication, and Trust Governance: A ComparativeStudy of Estonia and Singapore

Abstract

This article examines how digital public infrastructure shapes crisis communication, media governance,
public trust, and social development through a comparative case study of Estonia and Singapore. It argues
that digital government platforms, identity systems, cybersecurity frameworks, data-exchange infrastructures,
and public communication portals have become central media institutions because they mediate citizens’
access to public information, emergency services, administrative rights, and state legitimacy. Drawing on
comparative media systems theory, digital government studies, crisis communication, platform governance,
and institutional communication theory, the article compares Estonia’s decentralized, rights-oriented,
interoperability-based e-government model with Singapore’s centralized, smart-nation, state-capacity-driven
model. Empirically, the study analyzes UN e-government data, OECD digital public infrastructure reports,
national digital strategies, Smart Nation documents, e-Estonia materials, Reuters Institute news-use evidence,
cybersecurity and public communication frameworks, and scholarly literature. The findings indicate that
Estonia emphasizes distributed digital identity, data interoperability, transparency, and resilience after
historical cybersecurity threats, whereas Singapore emphasizes integrated service delivery, anticipatory
governance, digital inclusion, cyber safety, and whole-of-nation communication capacity. The comparison
reveals that digital public infrastructure influences democratic and developmental outcomes through four
mechanisms: communicative access, institutional coordination, crisis responsiveness, and trust production.
The article contributes to Communication and Media Studies by theorizing digital public infrastructure as a
communication-governance institution that links media systems, administrative communication, platformized
