PurposeInternational entrepreneurship (IE) has received a considerable amount of attention in the recent decades as a result of globalization enabling access to new international markets and business opportunities. Despite the growing increase in academic publications, IE still faces certain inconsistencies, with doubts remaining as regards its boundaries and the thematic groups making up the field. The purpose of this article is to systematically analyse the IE, mapping the intellectual territory and the evolution of the field.Design/methodology/approachIndexed to Web of Science( WoS) database until 2021, from 52 journals, 130 articles were selected, applying content analyses techniques to identify the main research lines.FindingsThe results reveal that IE presents four conceptual themes/clusters: (1) international business networks and opportunities; (2) institutional environments; (3) the characteristics and motivations of entrepreneurs; and (4) internationalisation drivers and processes. Extant analysis show that IE has progressed immensely, concentrating a good diversity of subtopics and research trends. An integrative framework bringing together 27 years of publications and 67 future research lines, detailed by cluster, were also presented in this study to improve understanding and guide future studies.Originality/valueThis review makes a broad contribution to the IE literature, assisting in consolidating the academic field, expanding and complementing the results of previous theoretical–conceptual studies. We reflect and individually discuss the state of the art of the four streams that characterize IE to identify key themes, points of convergence and advance new subfields.
