In the present paper based on the database of our own research from 2012 we examine with the help of some dimensions of national culture how the business behaviour of representatives of small-and medium-sized enterprises (henceforth SMEs) can be characterised in cross-cultural interaction situations. Previous pieces of research (e.g. Hofstede 1980, Bartlett-Ghoshal 1990) have already verifi ed that the norms, habits and behaviour patterns learnt as part of national culture strongly influence the behaviour of the members of the society therefore the business behaviour of employees as well, however, according to our hypothesis the business behaviour of representatives of SMEs is not unifi ed in cross-cultural interaction situations but can be subdivided into different categories. One novelty of our paper is that our research was concentrated on a geographical area since the sample included only representatives of Hungarian SMEs from the three counties of West-Transdanubian region with the condition that they participate in cross-cultural business relations with Austrian partner. The other novelty of the research is that the business behaviour of the respondent representatives was analysed by using some national culture dimensions of three researchers (Hofstede 1980, Trompenaars 1995, Hall 1975 and 1990), but based on the fi ndings the culture dimensions of a fourth researcher, Gesteland (2005) were outlined from the data. In our paper we fi rst introduce the theoretical background of the research, then we draw up its methodology, and fi nally as a result of our research we present the business behaviour of the representatives of SMEs from the examined region in cross-cultural interaction situations and its characteristics.
