Abstract
Over the past three decades, after Hofstede presented his proposal about cultural differences, many authors have presented their dimensions of national culture. The aim of this article is to give a synthesis of the proposal from significant authors and show a set of models of cultural dimensions based on theoretical and pragmatic analysis such as models of Hofstede, Trompenaars, GLOBE, Inglehart, Schartz. Also, examples used in this paper help more to understand the importance of research national culture.
