Abstract:Given the limited research on regional green innovation performance from a configurational perspective, this study investigates how the synergistic interactions among innovation elements influence regional green innovation levels. Building on the green innovation ecosystem theory, it develops a configurational analysis framework to evaluate the dynamics of collaborative interactions among innovation elements. Using fuzzy-set qualitative comparative analysis (fsQCA), four distinct configuration pathways driving high green innovation performance are identified, including: the“interaction and collaboration relationship-innovation resources-environmental policy”driven-model with the interaction and collaboration among green innovation elements as the core; the “interaction and collaboration relationship-innovation resources-natural environment pressure”driven-type centered on the interactive cooperation among green innovation elements; the“interaction and collaboration relationship-environmental policy”driven-type centered on interactive cooperation; the“interaction and collaboration relationship-natural environment”driven-type centered on interactive cooperation.The results demonstrate that interactive collaboration among green innovation elements is a core condition for achieving high regional green innovation performance (consistency score > 0.9). Based on these findings, it proposes that regions should establish a green innovation ecosystem mechanism centered on “interaction and collaboration among green innovation elements”, and align with their unique resource endowments, guided by the principles of adaptation to local conditions, leveraging comparative advantages, and compensating weaknesses through collaboration, in order to achieve a high regional green innovation performance via differentiated configuration pathways.
