Digital State Governance in Estonia and Poland: Institutional Architectures, Interoperability, and the Transition toward Proactive Public Services

Review

Lysiak, Molchanova, and Greben compare Estonia and Poland as two different institutional pathways toward increasingly proactive digital government. Their central claim is that digital-state maturity should be understood through the relationship among infrastructure, institutions, and service logic rather than through the volume of e-services alone. Estonia is characterised as infrastructure-led: secure digital identity, distributed registers, X-tee interoperability, and long-established once-only data reuse provide the base on which proactive and event-driven services are built. Poland is characterised as service-consolidation-led: sectoral systems, national portals, Trusted Profile, and mObywatel expanded first, while the state is now strengthening common architecture, interoperability, once-only data reuse, and whole-of-government coordination.

The paper’s strongest contribution is its emphasis on institutional sequencing. It shows that similar policy goals can emerge from different starting architectures, but the order in which capabilities are institutionalised shapes later governance options. Estonia’s model makes interoperability a shared state capability before service integration; Poland is attempting to deepen common infrastructure after substantial citizen-facing digitalisation. This distinction matters because proactive services depend on the state being able to reuse authoritative data across organisational boundaries under common legal, security, and accountability arrangements. A portal can aggregate access without creating that underlying governance capacity.

The treatment of interoperability is particularly useful because X-tee is presented not as a central database but as a governed exchange layer among autonomous systems. Its significance lies in authenticated, encrypted, signed, and logged transactions combined with distributed responsibility for source systems. This supports a broader digital-public-infrastructure proposition: interoperability becomes governable when technical exchange is coupled to institutional ownership, legal duties, auditability, and common rules. The paper similarly links digital identity to service architecture rather than treating authentication as a standalone technology.

The comparison is methodologically appropriate but bounded. It is based on national strategies, official infrastructure documentation, European Commission assessments, OECD material, and academic literature. That evidence is well suited to comparing institutional design and declared direction, but it does not establish that national strategies have been implemented uniformly or that the two models produce different causal effects on service quality, costs, citizen trust, or administrative burden. The authors acknowledge this directly: municipal, agency, and sectoral variation are outside scope, and strategy documents indicate intended direction rather than completed implementation.

That limitation becomes especially important in the convergence argument. Poland’s 2035 strategy may move decisively toward common architecture and once-only data reuse, but the governance test is whether those requirements alter agency-level processes, data stewardship, procurement, and local implementation rather than remain formal standards. Estonia’s mature infrastructure also does not eliminate governance risk. Greater integration concentrates dependency on shared identity, data exchange, cybersecurity, and service-continuity arrangements, while proactive services increase the need for citizen visibility, contestability, and evidence of lawful data use.

The paper’s most durable insight is therefore not that Estonia represents a model to copy or that Poland is converging on it. It is that digital government becomes infrastructure when reusable institutional capabilities shape how agencies may exchange data, recognise identity, coordinate decisions, and design services. Proactive government is downstream of those governance arrangements. AI intensifies this dependency rather than replacing it, because automated public services require reliable authoritative data, interoperable systems, audit trails, accountable decision processes, and institutions capable of sustaining them.

Key Insight

Proactive digital government depends less on the number of online services than on whether identity, authoritative data, interoperability, auditability, and whole-of-government coordination have been institutionalised as reusable infrastructure.
