1) The document summarizes the SI-DRIVE project which continues research on social innovation begun in the TEPSIE project. SI-DRIVE aims to further the understanding of social innovation through comprehensive mapping and case studies. 2) SI-DRIVE will map over 1,000 social innovation cases across different world regions and policy fields, then select 300 cases for further analysis and ultimately 70 cases for in-depth case studies. 3) The research will examine social innovation through several theoretical lenses and dimensions including concepts, societal needs addressed, resources/actors, governance, and process dynamics.
