This paper investigates the Moderating effect of entrepreneurial orientation on the relationship between knowledge based resource and international performance in Korean Ventures. VRIO literature revealed that an appropriate alignment between firm strategic orientation(O) and resource combination(VRI) is critical because of its impact on firm performance. The alignment is especially crucial for SMEs as a result of their limited resource base. However, studies have not adequately accounted for the joint effect of entrepreneurial orientation(strategic orientation) and knowledge based resources(resource combination) on firm performance in different environments as foreign markets. Drawing upon a sample of 217 internationalized Korean Venture Business, it presents evidence related to mainly moderating effects of entrepreneurial orientation(strategic orientation) on knowledge based resources(resource combination)-international performance. The Key conclusion from the evidence is that entrepreneurial orientation(strategic orientation), alone and in conjunction with certain knowledge based resources(resource combination) dimensions, is positively related to firm international performance.
