Assessing SMEs' internationalisation strategies in action

In this paper, a structured review was conducted to investigate the internationalisation process of small and medium enterprises (SMEs) to define barriers and enablers and identify research gaps in this relevant field. Data were collected from two databases of scientific peer-reviewed articles (i.e., Scopus andWeb of Science). After the selection process, 161 papers focusing on SMEs' internalisation were analysed using both descriptive and content analysis. The analysis of the results highlights that SMEs' internalisation is a growing research field, but different research gaps remain to be filled. These gaps concern barriers, impact on performance, models, and theories related to the different phases of the internationalisation process (e.g., start-up, early entrance, international growth). The future research directions identified interesting suggestions and guidelines for future researchers in the field of SMEs internationalisation.
