The evolution of a technological system: the case of CNC machine tools in Korea

Abstract.

Focusing on a product, this paper reconstructs the concept of technological systems first introduced by Carlsson and Stankiewicz (1991) in this Journal. Based on the model, we analyze the evolution process and performance of Korea's technological system for computer numerically controlled (CNC) machine tools as a catching-up case. The study shows that the length of 'learning period' for the system was substantial, even in a catching-up case. Especially, in the Korean case, the government played a 'macro-entrepreneurial' role in the molding of the technological system by giving legitimacy to the system, by mobilizing a nation-specific industrial organization of Chaebol system, and by enhancing the academia-industry-research institution links.
