The occurrence and scientific investigation of the phenomenon of social entrepreneurship are rather new. The term is very popular among politicians and is reflected in a lot of the political demands and willingness that they express. However, a review of the literature about it shows that there is no common ground or frame, and the historical developments are different in different countries and economies. Based on a study of the literature, a two-phase survey following the ‘Policy Delphi’ approach was conducted in Germany in order to enlighten this frameless picture of social entrepreneurship. Our results indicate five dimensions that extend the core
term: ‘social’, namely ‘Societal–Visionary’, ‘Ecological’, ‘Societal–Entrepreneurial’, ‘Economic’, and ‘Innovative–Entrepreneurial’. The degree of intercorrelation among the five dimensions shows that four factors, namely ‘Societal–Visionary’, ‘Societal–Entrepreneurial’, ‘Economic’, and ‘Innovative–Entrepreneurial’, have low to medium-high correlations. The fifth factor, ‘Ecological’, has the weakest correlation with all other factors.
