The document discusses factors that influence innovation ecosystems based on interviews with 25 Israeli innovation leaders. It finds that while the key factors identified in literature - government, academia, venture funding, culture and technology - also influence Israel's system, the relative importance of each factor differs from prevailing perceptions. Specifically, culture was seen as making a major contribution, while government and academia's impacts were viewed as more moderate. This discrepancy may be due to ecosystems evolving over time, changing each factor's nature of contribution.
