5. Conclusions
In this paper we presented a short review of the social innovation literature, focusing on the relationship between social innovation and sustainable urban development. We explored how off-the-shelf and bespoke technology has allowed the growth of people networks, and expanded the outreach of social innovation initiatives in the field of sustainability. By researching 29 cases across nine domains that emerged through the social innovation literature, and by analysing them comparatively, we detected four types of citizen profiles in the sustainability discourse: the ‘citizen-sensor’, the ‘sharing citizen’, the ‘collaborative citizen’ and the ‘entrepreneurial citizen’.
The foremost observation to make from the above analysis is related to the roles citizens acquire in the social innovation for sustainability discourse. Building upon the existing body of literature that explores the social aspect of innovation in terms of process and empowerment, we maintain that different citizen roles imply different capabilities and interrelations and, therefore, different dynamics for the social innovation ecosystem. In addition, these citizen roles are highly dependent on the type of ICTs and the way these tools are used. The blurred boundaries between users/consumers and producers and the emergence of “prosumers”11; as an expression of this blur, have been significantly encouraged by the extended use of ICT (Manzini, 2007; Millard et al., 2013; Wallin, Horelli, & Saad-Sulonen, 2010). However, this relation between citizen roles and ICTs needs to be further investigated. The current research stands for a first attempt to investigate this relation between citizen and ICTs, identifying citizen profiles in the area of social innovation regarding environmental sustainability.
