This paper integrates and expands the 4I model of organizational learning process and the SECI model of knowledge innovation based on the theory of organizational learning and knowledge management. It presents the corresponding relationships between the three levels of learning (individual, group and organization) and two types of knowledge (tacit and explicit), and then explores how the transformation of tacit-explicit knowledge fits the dynamic process of organizational learning. We find that the knowledge transformation is not a one-way process, but a spiral cycling one which contains the continuous knowledge innovation; the information technology will promote the combination of organizational learning and knowledge transformation meanwhile. Finally, a case study is presented to demonstrate the positive impacts of information technology on the organizational learning and the knowledge transformation.
