Our research aims to explore the relationship between information sources, absorptive capacity and innovation in a sample of Moroccan SMEs in the region of Souss-Massa-Draa. Indeed, we searched through an empirical study to understand the effect of absorption on the processing of information in innovation by SMEs in the context of a developing country like Morocco. Our results show that information networks offering new non-routine information and who are considered weak signals, contribute most to innovation in SMEs. Moreover, most SMEs have the ability to absorb information from its environment, the greater the magnitude of innovations is important. These results confirm the moderating effect of absorptive capacity in the transformation of information into innovation, and can be used to establish within SMEs a competitive intelligence system whose purpose is the collection of information and its operation. These results also emphasize the role of training of human resources as pillars of exploitation of information and its translation into innovation.
