The purpose of this study is to newly propose technology characteristic factors that influence dominant design determination and to construct theoretical rationale for these concepts. While existing studies on the concept of dominant design have generally taken a strategic management perspective centered on factors external to technology, this study focused on the inherent characteristics of technology itself and sought to highlight how the dynamics of the competitive process for dominant design vary according to these characteristics. The three technology characteristic factors proposed by the research team are: technology-market requirement fit, inter-firm technological cooperation potential, and technology application versatility. To verify the empirical validity of the proposed concepts, a case study of the LCD versus PDP technology competition in the display market was developed, and the roles that the proposed technology characteristic factors played in the competitive process for dominant design between LCD and PDP technologies were analyzed. The research findings showed that, first, the more suitable the characteristics of the technology chosen during the initial technology selection process are to evolving market requirements through product specifications and performance, the higher the likelihood that products utilizing that technology will be selected as the dominant design. Second, the higher the inter-firm technological cooperation potential in the product architecture and manufacturing processes where technology characteristics are reflected, the more product innovation is stimulated, increasing the likelihood of being selected as the dominant design. Finally, the more diverse the product categories to which the initially selected technology can be applied, the more favorably it acts in the dominant design determination process through economies of scale and risk diversification. The results of this study suggest that if strategies are built and executed based on an understanding of the inherent characteristics of technology, this can not only stimulate technology diffusion but also position firms advantageously in the dominant design determination process. Additionally, this study sought to propose a new methodological alternative that could encourage research on dominant design, an area where empirical research has been insufficient due to data scarcity.
