Focusing on the chemical industry, this paper examines the co-evolution of systems of component technologies within industry structures, and vice versa, in an open-ended process of interaction, continuous change and adaptation. The empirical evidence is based on patenting activity 1890-1990, matched with qualitative data. Three distinct periods of technology system takeoff are identified. We found a technology system perspective with competence bloc dynamics a very useful analytical tool to show systems becoming more complex and industry boundaries more blurred.
