Abstract We explore the roles that potential and realized absorptive capacity play in enhancing firm performance, and examine external knowledge search strategies as antecedents of absorptive capacity. In this way, we endeavor to open the black box that sits between external knowledge search and performance, and suggest that the establishment of deep and broad relationships with external sources has differing impacts on potential and realized absorptive capacity for the firm. We argue that distinguishing clearly between potential and realized absorptive capacity may provide new insights into understanding why some companies are more successful than others at benefiting from external knowledge. A sample of 171 suppliers operating in the Iranian automotive industry is used to test the proposed theoretical model, through a two-stage least squares approach. Surprisingly, our results indicate that only the firm's capability to acquire and assimilate new ideas from the external environment (potential absorptive capacity) is related to performance for these firms operating in Iran, which been isolated from global markets due to international sanctions. Our findings emphasize the notion that potential and realized absorptive capacity represent distinct capabilities, with different antecedents and different impacts on firm performance.
