Using bibliometric techniques to identify connections between existing entrepreneurship studies, this article seeks to understand the scientific structure of entrepreneurship research and how entrepreneurship scholarship is organized. Co-citation data and quantitative approach were used to identify scientific publications, intellectual structures, and research trends interrelated with theories of innovative entrepreneurship. Data were gathered from the citations and co-citations found in the Science Citation Index Expanded , Social Science Citation Index , and Arts and Humanities Citation Index . Our research reveals six groups of underlying entrepreneurship theories: (1) knowledge spillover theory of entrepreneurship, (2) creation and networks theory, (3) decision-making theory, (4) specialization of labor, (5) social entrepreneurship theory, and (6) entrepreneurship in the informal economy.
