Citizen participation in policy-making has become a defining feature of contemporary democratic governance, yet its effectiveness varies across political, social, and technological contexts. This narrative review aims to synthesize evidence on mechanisms of citizen engagement, influencing factors, and governance outcomes. Literature searches were conducted across Scopus, Web of Science, and Google Scholar using targeted keywords such as public participation, participatory governance, and deliberative democracy. Inclusion criteria focused on empirical and conceptual studies addressing citizen engagement in policy-making, while both qualitative and quantitative designs were considered. The results show that mechanisms such as Participatory Action Research, Citizen Advisory Boards, and digital platforms facilitate transparency, accountability, and trust when effectively institutionalized. Comparative evidence from contexts including Japan, Indonesia, and Europe demonstrates that participatory models enhance policy legitimacy and responsiveness but require adaptation to local cultures and institutional capacities. However, systemic barriers—ranging from political dominance and socio-economic inequalities to digital literacy gaps—continue to hinder inclusivity and long-term sustainability. These findings emphasize the importance of embedding participatory mechanisms within institutional and legal frameworks while leveraging information and communication technologies to broaden access.This review concludes that citizen engagement is both a normative imperative and a practical strategy for improving governance. Future research should explore cross-country comparisons, develop long-term evaluation metrics, and examine how marginalized populations can be more effectively integrated. Strengthening participatory governance is crucial for advancing transparency, accountability, and democratic resilience.
