This study examines the relationship between internationalization orientation and international performance of small and medium-sized enterprises (SMEs), and the mediating effect of technological innovation. Prior research suggests that internationalization is a prominent strategic choice for SMEs to gain growth and profitability. However, there is still no explicit agreement on how internationalization affects international performance. Similarly, the role of innovation on performance has long been emphasized, but the implications of technological innovation on international performance are still eluding us. Our investigation of 116 SMEs in the United Kingdom reveals that internationalization orientation has a significant effect on their international performance. SMEs that have a strong international orientation can achieve better international firm performance. In addition, the results indicate that technological innovation positively mediates the effect of internationalization orientation on international firm performance. The findings of this study suggest that managers can improve international performance by combining inward and outward internationalization orientation with technological innovation activities in their strategic decisions.
