Leveraging diverse ecosystem partners for innovation: the roles of regional innovation environment and partnership heterogeneity

Although prior studies investigated the influence of partner diversity on focal firms' innovation performance, they failed to consider partners' ecosystem positions and the roles of regional innovation environment and partnership heterogeneity. To fill these gaps, this study examines the relationship between supplier diversity, customer diversity, regional innovation environment, partnership heterogeneity and innovation performance to provide a comprehensive and throughout understanding of the influence of partner diversity on innovation performance. Based on data of 188 Chinese manufacturing firms, this article finds that both diversities of upstream suppliers and that of downstream customers contribute to innovation performance. Regional innovation environment and partnership heterogeneity moderate the influences of supplier diversity and customer diversity on innovation performance. In a favourable regional innovation environment, the benefits of diverse upstream suppliers for innovation are eroded, while the benefits of diverse downstream customers for innovation are enhanced. Partnership heterogeneity with suppliers can mitigate the moderating effect of regional innovation environment on the relationship between supplier diversity and innovation performance. These findings advance the literature on partner diversity and innovation performance, thus providing fine-grained managerial implications to firms to orchestrate diverse inter-organizational partners for innovation.
