The smart city concept encompasses and covers various societal issues. As such, it can sometimes sound nebulous and ambiguous to local decision-makers. From one municipality to another, different visions and meanings of the smart city—ranging from a reductionist understanding based on technological determinism to a more holistic, socio-technical view— can coexist and adapt to local specificities and contexts. Thus, each territory develops its own vision of the smart city according to its challenges. All this may impact the implementation of smart city policies. Drawing from the extensive literature on digital government in public policy and administration as well as public management, this article investigates how local decision-makers differently portray the concept of smart city and how they discursively construct and legitimize their own vision of the concept. We analyze the Belgian “Intelligent Territory” call for projects, initiated in 2019 by the Walloon Region. In particular, a quantitative and qualitative content analysis of 88 projects submitted by various Walloon towns, municipalities and inter-municipalities is carried out. More precisely, we explore the motivations for implementing smart city policies put forward in their project by local decision-makers. The empirical results highlight the diversity of visions of the concept of smart city that exist in Wallonia city governments. We identify ten categories which offer an original classification of the opportunities offered by smart city policies according to local decision-makers. Our findings suggest that there is no one-size-fits-all approach for smart city development. Overall, this study contributes to our understanding of the (varieties of) discursive logics underpinning the construction of digital and smart city policy realities.
