Session 3(9/21) : Technological Changes : Giovanni Dosi (1982). Technological paradigms and technological trajectories: A suggested interpretation of the determinants and directions of technical change Kim, Yongwon Phd. candidate Management of Technology Summary of the paper The relationship between economic growth and technological change is controversial pretty. In this article, the theory of technological change is significantly separated by the two views -demand pull / technology-push. Especially, the differences between the two perspectives were mentioned. Signals of the market were very important to identify the need in demand-pull. But market signals are very abstract and cannot explain the long-term technological innovation and product development, and the time-lag. This article is also described about the relationship technology paradigm and technology trajectory through the relationship of science - technology – products. In other words, the author comprehensively defines scientific paradigms and technological paradigms in Kuhn's position. The reason for choosing the technological paradigm is described in terms of problem-solving process and technology evolution of Nelson & Winter. Also, the author is claimed that economic, institutional, and social factors are driving technological progress, and the cost problem such as IR & Tayloristic and economies of scale is an important source of technological evolution. Finally, in the process of product innovation, the author talked about the importance of the market. It is very important to detect the mutation of the market in terms of evolutionary changes. In addition, from the perspective of Schumpeterian, because market provides compensation to the company, where an attempt is made to risk-taking which give rise to the technological advances occurs. Main Contribution This article describes continuity versus discontinuity in technical change. This can be interpreted as incremental innovation and radical innovation. This article explains that the process of new product innovation does not happen by accident. Finally, this article explains that technological advances have made cumulatively. Critique This article has some to be desired as followed. At first, the author have been accepted Kuhn and Nelson & Winter's view of the position at the same time. Kuhn has the materialist position and his opinion is different from an evolutionary perspective. Nelson & Winter, however, has an evolutionary perspective. At the same time, two views that cannot be compatible explain the phenomenon. Another problem is that this article uses the theory without a criticism. For example, the theory of demand pull is used to describe products innovation and Schumpeter's opinion of the market is only used to describe the effects. Rather than presenting a new theory, the theories have been adjusted to his framework. 1/1
