The aim of this paper is double. First, it provides a conceptual framework linking human resource management, organisational learning and knowledge management. Second, the paper builds a causal model and tests it with a sample of firms from the Spanish manufacturing industry, using a structural equation modelling technique. In particular, after the performance of a cluster analysis, a group of 72 learning firms is identified and used to test our model. Finally, major conclusions and implications for management are drawn and further avenues for research are suggested. (Contains 1 note, 6 tables, and 3 figures.)
