Abstract: The economic literature presents knowledge accumulation as one of the most important characteristics of innovation. The accumulation of knowledge arises from complex and dynamic interactions between a firm’s own internal capacity and external expertise. Research and development (R&D) remains important in the innovation process, but it must be integrated with knowledge from other sources, such as training and knowledge capitalization. This paper investigates the relationship between such knowledge sources and the productivity of French firms. Using asymptotic least squares, a Cobb-Douglas function including R&D, innovation, training expenditure and ISO 9000 certification is estimated for 1,213 French manufacturing firms. Our results show that innovation, training and ISO 9000 certification have a positive and significant impact on firms’ productivity. Copyright Springer Science+Business Media, LLC 2012
