FIRST‐MOVER ADVANTAGE: THE OPPORTUNITY CURVE
提出了一个先发者动态模型，认为战略壁垒中的独特性壁垒最能维持先发优势，并通过六个行业的实证发现，行业份额和利润份额随行业年龄呈指数衰减，形成机会曲线。
ABSTRACT A model depicting first‐mover dynamics is proposed wherein certain types of strategic barriers activated by the first‐mover strategy figure prominently in preserving benefits in the time dimension. Strategic barriers conferring singularity (i.e. one‐time benefit) are considered to be the most effective preservers of first‐mover advantage. the theoretical model is tested empirically in a study of six major industries. Benefits operationalized as industry share and profit share were found to decline consistently with industry age according to an exponential function designated the opportunity curve.
