技术领先地位在不同时期从一个国家转移到另一个国家。我们提出了一种机制，解释了两国模型中技术跨越的永无止境的循环，包括对无限消费者的动态优化。在该模型中，由于国内创新和外国创新的溢出，每个国家随着时间的推移积累了知识存量。我们发现，如果国际知识溢出是合理有效的，技术领导力可能会首先从一个国家转移到另一个国家，然后沿着均衡路径在国家之间交替。
Technological leadership has shifted at various times from one country to another. We propose a mechanism that explains this perpetual cycle of technological leapfrogging in a two-country model including the dynamic optimization of an infinitely lived consumer. In the model, each country accumulates knowledge stock over time because of domestic innovation and spillovers from foreign innovation. We show that if the international knowledge spillovers are reasonably efficient, technological leadership may shift first from one country to another, and then alternate between countries along an equilibrium path.
