Abstract
Scholars have long studied small- and medium-sized enterprises (SMEs) and recognize the need for SMEs to postulate strategies to compete and succeed in the global market. In the current ultra-competitive business environment, SMEs face several internal and external challenges. In this introduction to the special issue (SI), we review the theoretical models and frameworks in this stream of research and outline some research questions that could be potentially used in future research in this era of globalization. The six papers selected for inclusion in this SI analyze this field from different angles, offering interesting overviews on the present situation of research in the field, as well as relevant new findings and perspectives for future research.
