SME Internalisation Index (SMINI) Based on the Sample of the Visegrad Countries

The goal of the chapter is to develop an index (Small and Medium-Sized Enterprise Internationalisation Index – SMINI) to measure the degree of internationalisation in the SME sector, and to uncover its most important influencing factors. The index was calculated from a data set obtained from a questionnaire conducted among 1,124 firms from the Visegrad (V4) countries, comprised of 270 Polish, 597 Czech, 113 Hungarian and 144 Slovak firms. The relationship between the index value and the influencing factors was also tested using the same dataset. The influencing factors were chosen based on a literature review. We found that the factors suggested by the literature (company size, company age, ownership structure, innovation activity, network participation and sectorial structure) have a significant effect on the SMINI, but the strength of relationship is either weak or weak to moderate. A multiway ANOVA analysis revealed that three of our variables – firm size, family ownership and innovation – have an 11.8% combined effect on the SMINI.
