SME internationalisation process: Key issues and contributions, existing gaps and the future research agenda

The literature that studies internationalisation of small and medium-sized enterprises (SMEs), despite being only recent, has already become very extensive and fragmented, taking different approaches and contributing across diverse facets of internationalisation. There is also a need to analyse and systematise those issues that have received the attention in the field of SME internationalisation. This study aims to develop a systematic literature review on SME internationalisation. We correspondingly make recourse to the Web of Science and Scopus database, and analyse a total of 366 articles, spanning the period from 1995 to 2017, to identify the core issues and contributions made by the existing literature. The results enable the categorisation of the existing literature into three main areas of research: i) Internationalisation process, ii) Specific factors/variables influencing internationalisation; and iii) Internationalisation and performance. This structuring then establishes the grounds for grasping the gaps existing in the literature and to propose a future research agenda. •We present a systematic literature review of SME internationalisation.•We found a categorisation of the existing literature into three main clusters.•We identified the main gaps and propose a future research agenda.•This study holds direct implications for the literature on this field.
