Entrepreneurial ecosystems are incubators of start-up businesses, providing a nurturing environment, resources, and the context for start-up activity to flourish. Entrepreneurial activity from the perspective of an ecosystem is not well understood, and the flow of resources across levels has received limited research attention. While in general, the resources within an ecosystem have been considered from a top-down view as influential on start-up activity, there is little research on how resources that are held by individuals and organizations emerge as specific properties of the ecosystem. We contribute to the literature by providing a multilevel lens to understand the emergence of resources as the property of the ecosystem. By exploring the process of emergence of ecosystem resources, we bring forth implications that extend beyond the provisioning of resources to the ecosystem to highlight the importance of meso level structures that reinforce coalesced attributes of an ecosystem.
