Abstract The strategic group concept provides an attractive middle ground between firm and industry for both theory development and empirical analysis. To date, this concept has been defined by researchers in terms of secondary accounting and financial data, and a number of critics have questioned the validity of this work. Our research shows that industry participants share perceptions about strategic commonalities among firms, and that participants cluster competitors in subtle ways not reflected in extant academic research on strategic groups. Decision makers' perceptions and cognitions are phenomena that can be expected to influence industry evolution. They are of research interest as an additional source of data on firm commonalities which helps address concerns about previous strategic group research.
