An evolutionary perspective on strategic group emergence: a genetic algorithm‐based model
通过模拟模型研究战略群体在什么条件下涌现以及群体间绩效差异为何持续，发现移动壁垒、战略互动、动态能力和竞争边界共同决定战略群体的形成与稳定。
Abstract We develop a simulation model to examine conditions under which strategic groups emerge and their performance difference persists. In our model, mobility barriers, strategic interactions among high performers, dynamic capabilities (the mechanisms that allow winners to continue to survive), and boundary of rivalry are put together to derive their joint implications for the evolution of strategic groups. Not surprisingly, our model behavior shows that mobility barriers and strategic interactions play an important role in sustaining intergroup performance difference. However, the extremely high level of mobility barriers is shown to impede the emergence of strategic groups. We also find that dynamic capabilities and boundary of rivalry are as essential as mobility barriers in understanding the emergence and stability of strategic groups. When dynamic capabilities are absent or when rivalry is extended over firms with dissimilar strategies, strategic groups are less likely to exist. These findings can serve as a guideline for empirical research to probe why strategic groups exist sometimes and why they do not at other times. Copyright © 2002 John Wiley & Sons, Ltd.
