Given the inherent risk of innovative activity, multiple parallel approaches to innovation can improve the odds of success. Since innovation draws on many sources of ideas, firms also may improve their odds of successful innovation by accessing a large number of knowledge sources. In this study, we conduct one of the first firm-level statistical analyses of the impact on innovation of breadth in both innovation objectives and knowledge sources. The analysis utilizes detailed data on the innovation activities of firms for a broad cross-section of firms and industries in the Finnish economy. The results suggest that broader horizons with respect to innovation objectives and knowledge sources are associated with successful innovation.
