Central Place Theory and City Size Distribution
通过均衡进入模型形式化中心地理论，研究城市规模分布如何遵循幂律，发现商品规模经济的异质性是驱动城市规模差异的关键因素。
This article proposes a theory of city size distribution via a hierarchy approach rather than the popular random growth process. It does so by formalising central place theory using an equilibrium entry model and specifying the conditions under which city size distribution follows a power law. The force driving the city size differences in this model is the heterogeneity in economies of scale across goods. The city size distribution under a central place hierarchy exhibits a power law if the distribution of scale economies is regularly varying, which is a general class that encompasses many well‐known, commonly used distributions.
