Citizen Engagement and Participation in Smart Cities: Scope and Definition of Concept
Smart city initiatives increasingly claim to be citizen-centric, yet governance frameworks persistently conflate two analytically distinct concepts, citizen participation and citizen engagement, in ways that undermine the design and evaluation of civic involvement mechanisms. This conceptual ambiguity represents a structural problem in the field, not a transitional oversight, and carries direct consequences for how urban managers design governance instruments and measure their effectiveness. This study systematically examines the scope, definition, and operationalization of both concepts in smart city research through a Systematic Literature Review (SLR) following the SPAR-4-SLR protocol. A corpus of 43 peer-reviewed articles published between 2011 and 2025, retrieved from Scopus and Web of Science, was subjected to qualitative content analysis using a structured coding framework. Findings reveal that 53% of reviewed studies use participation and engagement interchangeably, a pattern that remains stable across all publication periods, confirming the structural rather than incidental nature of the ambiguity. Only 26% of articles establish a rigorous conceptual distinction and operationalize both terms through distinct analytical frameworks. The review further identifies a critical mechanism design gap: 30% of articles report no engagement mechanism whatsoever, and only 23% report outcomes with verifiable indicators. Based on these findings, this study proposes a conceptual framework that explicitly distinguishes participation, as a behavioral, often episodic act, from engagement, as a sustained, intrinsically motivated process characterized by genuine influence over governance outcomes. The framework offers researchers a theoretically grounded basis for construct differentiation and provides urban managers with actionable criteria for designing governance mechanisms that move beyond symbolic consultation toward authentic co-creation. Implications for digital governance research and smart city policy are discussed, with particular attention to underrepresented contexts in the Global South.
