Barriers to entry and competitive strategies
研究了五个不同结构行业的进入难度与竞争策略的关系，发现事前分析进入壁垒和预测企业反应有价值，尤其是闲置产能可有效阻止新进入者。
Abstract The relationships between the difficulty of entry and competitive strategies in five industries, chosen for their differing structural contexts, were tested. Statistical support was found for the value of pre‐entry analysis of entry barriers and of firms' predicted responses to potential entry. In particular, the creation of idle productive capacity appears to be a potent deterrent to new entrants.
