| Abstract: |
This study conducts a quantitative analysis of the relationship between
mainstream formation and competition in technological fields. The process of
determining the dominant design is crucial in analyzing mainstream formation
within specific technological fields, and numerous studies have explored this
process. The quantitative analysis conducted in this study indicates that,
during the process in which the dominant design is determined, the dominant
category, a broader framework than the dominant design, is also established.
In this study, we use topic modeling analysis to examine the relationship
between the convergence of research and development (R&D) trends among
organizations and the number of organizations publishing patents in the
computer graphics processing systems industry. Specifically, the number of
organizations publishing patents in the industry increased when the degree of
convergence among the R&D trends of each organization was relatively low,
whereas it decreased when the degree of convergence among R&D trends of each
organization was relatively high. Further, the change in the degree of
convergence occurred before the change in the number of organizations. These
observations suggest that the formation of a mainstream within the industry,
which is associated with the convergence of R&D tendencies of specific
organizations, affects the competitive environment within the industry. |
