As discussion of innovation ecosystems remains near the front of science, technology, and innovation policy discussions — and resources are spent providing environments for creative exchange between researchers, industry, government, and entrepreneurs — substantive and empirical research is still lagging. However, a recent study sheds new light on the mechanisms and types of interactions that may contribute to the desired outcomes of promoting innovation ecosystems. Specifically, the study evaluates the effectiveness of combining two long-running, potentially complementary programs in encouraging increased engagement among ecosystem groups and individuals.
