What Is Going on with the Research into the Internationalization of Small and Medium-Sized Enterprises (SMEs)? An Intellectual Structure Analysis into the State-of-the-Art (1990–2018)

The internationalization of Small and Medium-sized Enterprises (SMEs) is a topic of constant research interest due to the impact these have on economic growth and employment in developed, emerging and developing countries. A desire to understand and a growing interest in the study of the internationalization process of SMEs has provoked a significant increase in the production of manuscripts in this field in the last decade. Therefore, it is necessary to carry out periodic reviews on the state-of-the-art of this phenomenon in order to highlight advances and limitations, to motivate reflections and stimulate progress in future research. Thus, the main objective of this study is to describe the state-of-the-art of the research into SME Internationalization based on a bibliometric analysis of 1152 manuscripts published from 1990 to 2018. The results enable the identification of the main agents that are constantly developing this field through an analysis of scientific production and collaboration indicators. Furthermore, through a co-word analysis, this research establishes hot-spot research trends that need to be developed in future research. The main contribution of this research is the configuration of a knowledge map on SME Internationalization research.
