In this article we explore the claim that spatial interactions among cities are significant drivers of their growth. We assert that reallocation of ideas among cities is a source of improved allocation of resources. We propose a closed economy, agent-based model that is in constant flux. It is populated by autonomous agents that compete and adjust constantly their behavior in reaction to the conditions they perceive. The economy is a dynamic, self-organizing system. We focus on the intensity of globalization as the critical economic process that explains differences in convergence and divergence in the system. The means by which the extent of globalization affects the long-run performance of economies is the geographic reach of new ideas and their conversion into innovations. The question that plays out in our model is the relative influence of globalization and the localized entrepreneurial ecology on innovation. When the globalization is weak, new firms are limited by the market value of their own city. As the globalization strengthens, more and more new firms belong to the global playground. We demonstrate that in line with empirical literature, the gross domestic product of our urban system increases greatly with the increase in globalization level.

在本文中，我们探讨了城市之间的空间互动是其增长的重要驱动力的说法。我们断言，在城市之间重新分配思想是改善资源分配的来源。我们提出了一个封闭的，基于代理的经济模型，该模型是不断变化的。它由自治的代理组成，这些代理根据他们所感知的条件不断竞争并不断调整自己的行为。经济是一个动态的，自组织的系统。我们将全球化的强度作为关键的经济过程，集中于解释系统趋同和分歧的差异。全球化程度影响经济体长期绩效的手段是新观念的地理范围及其将其转化为创新的方式。我们的模型中提出的问题是全球化和本地化的企业家生态学对创新的相对影响。当全球化薄弱时，新公司受到其所在城市市值的限制。随着全球化的加剧，越来越多的新公司加入了全球市场。我们证明，根据经验文献，随着全球化水平的提高，我们城市体系的国内生产总值大大增加。
