Abstract:    Under the policy guidance of enhancing the overall effectiveness of China′s innovation system and fostering an open innovation ecosystem with global competitiveness, the academic community has paid attention to how to improve the effectiveness of innovation ecosystems. This paper revealed the co-evolution mechanisms at both macro- and micro-levels for enhancing the effectiveness of open innovation ecosystems from the perspective of co-evolution. On this basis, it employed the qualitative research method to elucidate the core driving mechanisms for improving the effectiveness of open innovation ecosystems in the Chinese context and analyzed the effective paths for enhancing system effectiveness. The following conclusions were drawn from this research: (1) the core driving mechanism for improving the effectiveness of China′s open innovation ecosystem lies in the emergence and co-evolution of heterogeneous participants at the micro level, as well as the optimization of environmental factors that promote co-evolution at the macro level of the system; (2) the value proposition of "openness-symbiosis" plays a central leading role, enabling sustained improvement in ecosystem effectiveness; (3) fully respecting value co-creation is conducive to the formation of long-term ecological advantages within the ecosystem; and (4) the open and advanced manufacturing service capabilities have become a critical entry point for China′s open innovation ecosystem to maintain a high level of openness and enhance system effectiveness. This study has broadened the theoretical research on innovation ecosystems and it will provide some theoretical references and countermeasures for improving the effectiveness of China′s open innovation ecosystems.
