本文演示了如何增加竞争巩固优势的因果关系，我长期持久的优势。现有的持续支配地位理论预测，当资源变得广泛可用和竞争者数量增加时，支配地位的把握就会减弱。这一预测源于经济学的假设，即只有在竞争有限的情况下才有可能保持持续的主导地位;竞争者众多、资源广泛可及、没有进入壁垒的完全竞争市场，不可能为主导者提供维持其规模的基础。我挑战这一假设，首先认为，一个占主导地位的可以受益时，其竞争对手的数量增加，获得更多的消费者的认可，并面临较少的挑战，从其最近的竞争对手，然后断言，即使占主导地位的不直接受益，增加竞争可以减少非占主导地位的motility-magnitude的大小变化-trammeling他们的增长占主导地位的大小。数值模拟表明，减少运动显着延长了预期的统治时期，当许多新的竞争者进入市场。持久的主导地位扭转了对竞争动态的既定理解，随着市场变得全球化和金融化，可扩展的生产和分销资源变得广泛可用，对越来越多的环境产生影响。
This paper demonstrates how increased competition entrenches dominants-a causal relationship I term durable dominance. Established theories of sustained dominance predict that a dominant's grasp on its position weakens when resources become widely available and the number of competitors increases. This prediction stems from the assumption, from economics, that sustained dominance is only possible when competition is limited; perfectly competitive markets with large numbers of competitors, widely accessible resources, and no barriers to entry provide no basis for dominants to maintain their size. I challenge this assumption, first arguing that a dominant can benefit when the number of its competitors increases, garnering more consumer recognition and facing fewer challenges from its nearest competitors, then asserting that even when a dominant does not directly benefit, increased competition can decrease nondominants' motility-magnitude of size changes-trammeling their growth to dominant size. Numerical simulations show reduced motility significantly lengthens the expected duration of a dominant's reign when many new competitors enter the market. Durable dominance reverses established understandings of competitive dynamics and holds implications for an increasing number of settings as markets become global and financialized, and scalable resources for production and distribution become widely available.
