The purpose of this paper is to analyze the dynamic characteristics of innovation sources such as scientific knowledges, processing technologies and user's needs in advanced metals technology. The journal articles data of four advanced materials are analyzed; amorphous metals, superplastic materials, shape memory alloys and aluminum-lithium alloy. Some regularities are found from the analysis of the four materials. The innovation proceeds through close interactions among the innovation sources. As the innovation proceeds, the relative importance of each source changes: scientific knowledge initiates the innovation and becomes the most important source in the first phase, then the processing technologies increase importance in the second phase, and then scientific knowledge, again, becomes the leading factor of innovation. Scientific knowledge and processing technology take turns leading the innovation. The impacts of users' needs to the innovation increase more and more as innovation proceeds. The results of analysis imply to the policy makers that emphasis of policy, and therefore the allocation of sources for innovation, should vary along the phases in the life cycle of advanced metals technology.
