This report analyses the role of foundations, funding and/or carrying out research and innovation programs in Bulgaria supporting the development of science and scientific institutions. In particular, we examine the types of foundations; origin of their funds and main sources of funding; their investments in research and innovation; supported key research areas; their role in the sphere of research and innovation. Empirical data in the report were collected through a large-scale survey of EU foundations and NGOs, funding and/or engaged in research and innovation, where ISSK β BAS was the Bulgarian partner. The survey was funded by the European Commission and was carried out in the period 2013-2014 in all EU Member States plus Switzerland and Norway.
