The term ‘social innovation’ becomes more and more significant in social and political discourse. However, so far there is still no theoretically grounded, practicable concept of social innovation. Through recourse to the social theory of Gabriel Tarde, with its focus on social inventions and social practices of imitation, social innovation can be identified as a specific mechanism of change, and hence the analytical perspective can be directed towards society as a locus of innovation. This provides valuable input for an integrative theory of innovation, and for the analysis and shaping of social transformation processes (see http://www.sfs.tu-dortmund.de/cms/en/news/260215_news_publication_tarde/index.html).
