The role of international institutional complexity on emerging market multinational companies’ innovation

Research Summary This study examines the role of international institutional complexity, which is defined as the scope and multiplicity of institutional dimensions across foreign markets, on emerging market multinational companies’ ( EMMC s) innovation performance. We propose that international institutional complexity provides learning opportunities for EMMC s’ innovation performance but also incurs higher management costs to handle information overload from overextended internationalization. We further propose that the host exposure and the heterogeneity of an EMMC 's top management team ( TMT ) moderate the main effect of international institutional complexity on EMMC innovation. The empirical testing utilizes a longitudinal panel dataset of 7,072 foreign expansion steps by 767 C hinese firms from 2001 and 2010 and offers strong support for the proposed hypotheses. Managerial Summary Despite the emergence of EMMC s over the past 30 years, there is little understanding of how international institutional complexity impacts EMMC s’ innovation capabilities. By analyzing a longitudinal panel dataset of 7,072 foreign expansion steps by 767 C hinese firms from 2001 and 2010, we find that the international institutional complexity of an EMMC has an inverted U ‐shaped impact (first increasing and then decreasing) on its innovation, such that a moderate level of international institutional complexity generates the most innovation output. We also find that TMT host exposure and TMT heterogeneity positively moderate the relationship between international institutional complexity and EMMC s’ innovation performance. Our study contributes to better understanding EMMC s’ international strategies in enhancing their innovation capabilities.
