While the concept of innovation has become more and more important for societies to cope with the great societal challenges, technological and economic innovation encounters limitations in resolving them. To this end, Social Innovation has increasingly been attracting attention in recent years. As a novel approach to address complex problems in global health, social care, education, energy, and environmental policies, Social Innovation has been embraced by stakeholders and communities on the local, regional, and even national level (Franz et al. 2012; Moulaert et al. 2013; Nicholls et al. 2015; Howaldt et al. 2018, 2019; Mulgan 2019).
