International entrepreneurship: A critical analysis of studies in the past two decades and future directions for research

International entrepreneurship (IE) is an emerging field with a rapidly growing body of knowledge. This paper examines gaps, issues and trends of the IE in the last two decades. First, it suggests an integrative framework based on international business, entrepreneurship, strategic management, social network and marketing theories. The suggested model highlights the significant role played by the entrepreneur/team, firm and network resources that act as antecedents to international opportunity development and value innovation. Second, it suggests four typologies of firms (born global, enduring global, early exporter and mature exporter) that can be studied under the IE theme. Finally, we discuss future research directions.
