Given the looming significance of emerging multinational corporations, this article outlines the primary theoretical aspects pertaining to this growing phenomenon. The following four main aspects are covered: The concept of emerging multinational corporations, theories explaining their evolution, market penetration modes, and finally the types of such firms. Based on the motive of multinationality, it is proposed to classify the different theories into three groups, namely: Firm advantages (asset exploiting), host country advantages (asset seeking), and both firm and host country advantages. This article distinguishes between 10 different types of emerging multinational corporations, based on the timing and the motives for initiating the multinationality process, the relation between the headquarters and affiliates, and the geographical dispersion of foreign activities. Entry modes adopted by emerging multinational corporations vary significantly according to ownership, the nature of overseas’ operations, the control of parent firms over these activities, and the extent of externalising and internalising.
