Depth and breadth of external knowledge search and performance: The mediating role of absorptive capacity

Nowadays it is commonly accepted that exploiting external knowledge sources is important for firms' innovation and performance. However, it is still not clear how this effect takes place and what internal capabilities are involved in the process. We propose to open the black box between external knowledge search strategies, and innovation and performance by proposing absorptive capacity (AC) as the mediating variable. A sample of 102 biotechnology firms from Spain is used to test the proposed theoretical model through structural equation modeling taking the partial least squares approach. Results suggest that AC acts as a full mediator in the relationship between the depth of external knowl…
