Few studies have investigated sustainable management in the semiconductor industry. Consequently, this study analyzed the characteristics of companies excelling in sustainable management in the semiconductor industry using chief executive officer messages. It compared high- and low-performing groups to identify leading sustainable firms. Centrality analysis was conducted to extract keywords, which were mapped to the sustainability criteria to conduct network analysis. The results showed that the high-performing group emphasized sustainable development across the semiconductor industry ecosystem, while the low-performing group focused on internal sustainability aspects. This underscores the need for effective sustainable development in the semiconductor industry that extends beyond individual company efforts and embraces industry solidarity. Thus, this study presents a methodology that can be applied to similar studies in industries beyond semiconductors.
