Despite the growing trend among small and medium enterprises (SMEs) of utilizing the Internet for internationalization, academic research in this area remains sparse. This paper presents and empirically evaluates a theoretical framework of the effect of Internet capabilities, comprising platform and web capabilities, on export marketing capabilities and export performance for SMEs in emerging markets. Furthermore, we examine the contingencies in this relationship. Based on a sample of Chinese SMEs, our empirical findings indicate that platform and web capabilities are positively related to export marketing capabilities and export performance. Moreover, product complexity and competitive intensity moderate the effects of platform and web capabilities on export marketing capabilities. Additionally, we discuss the theoretical and managerial implications.
