“…Han, Lowik and de Weerd-Nederhof [34] have recognized common elements of different ecosystems, including focal roles, co-specialization, co-evolution and coopetition, pooled and loosely coupled interdependence, hierarchical structure, shared vision, system-level business model, and modularity. Further, ecosystems can be interpreted as nested in layers, ranging from micro-level (service exchange between actors) to interdependencies between co-existing ecosystems at mega-level [35]. Ecosystems have been used as a conceptual paradigm in the public sector, as seen, as an example, in the case study of a national health information system, where public and private health care organizations act in meso-level, and the whole ecosystem represents macro-level [36].…”
