The main research objectives of this paper are the analysis of the influence of international market orientation and the management capabilities derived from that orientation on international new ventures’ (INVs) behavior. Foreign market geographical diversification and the commitment involved in entry modes are considered to reflect this international behavior. Thus existing International Entrepreneurship literature is developed by analyzing the behavior of INVs explaining and testing how international market orientation and management capabilities affect geographical diversification and the commitment involved in entry modes. The empirical study confirms this influence.
