Barriers to innovation and innovation performance: the mediating role of external knowledge search in emerging economies

Using survey data from companies located in the Wuxi (Taihu) international science park in China, we aim to analyze to what extent science park residents experience barriers to innovation and to what extent opening up the innovation process allows them to overcome constraints and increase innovation performance. Findings indicate that surveyed firms that mostly undertake incremental innovation perceive many constraints and that the depth of external knowledge search—that is, the intensity of the relationship with external sources of knowledge—significantly influences innovation performance, mediating the relationships between innovation barriers and innovation performance. Our results allow us to explain how open innovation practices can be used to mitigate existing barriers, and therefore permeate the knowledge filter, and to theorize on the importance of institutional factors for open innovation theory in emerging economies.
