Smart cities are designed as a model of urban development based on information technology and networks, which implements advanced digital technologies and improves infrastructure and public services with efficiency in resource allocation and environmental sustainability: it aims to take cities to the next level, creating a more efficient and pleasant environment for citizens and businesses. Concurrently, when these kinds of technological solutions take place without the participation of local communities, they can cause social exclusion and a stigmatizing view of innovation. This article analyses the crucial role of social responsibility in promoting more inclusive smart cities, focusing on the involvement of communities in decision-making processes. The methodological approach combines a conceptual overview with the analysis of symbolic case studies. The review explores the concepts of participatory governance, inclusion, and urban sustainability, providing a conceptual framework for understanding how cities can incorporate social responsibility into their technological strategies. The analysis of case studies from Barcelona, Amsterdam, and Helsinki illustrates innovative community engagement practices, such as using digital platforms for direct participation, co-designing public spaces, and shared monitoring through participatory sensors. The results show the benefits of a participatory approach: involved communities show a greater sense of belonging and trust in institutions, while administrations improve the effectiveness of urban policies, reduce operational costs, and promote wider adoption of technologies. However, challenges remain, including technological accessibility and the need to overcome cultural and digital barriers.
