STRATEGIC TIME PERIODS AND STRATEGIC GROUPS RESEARCH: CONCEPTS AND AN EMPIRICAL EXAMPLE.

This article briefly reviews previous research on strategic groups and focuses upon the influence of time on strategic positioning. This stability approach also motivates research into the dynamics of strategic group shifts. An illustrative example drawn from the drug industry emphasizes the practical application of these concepts. The analytically-derived strategic groupings are then compared with evidence drawn from industry and academic research. Finally, following discussion of the results, some suggestions about integrating the strategic group concept into strategic management research are also made. [ABSTRACT FROM AUTHOR]
