英文摘要：
  The scaling of urban characteristics with total population has become an important research field since one needs to better understand the challenges of urban densification. Yet urban scaling research is largely disconnected from intra-urban structure. In contrast, the monocentric model of Alonso provides a residential choice-based theory to urban density profiles. However, it is silent about how these profiles scale with population, thus preventing empirical scaling studies to anchor in a strong micro-economic theory. This paper bridges this gap by introducing power laws for land, income and transport cost in the Alonso model. From this augmented model, we derive the conditions at which the equilibrium urban structure matches recent empirical findings about the scaling of urban land and population density profiles in European cities. We find that the Alonso model is theoretically compatible with the observed scaling of population density profiles and satisfactorily represents European cities. This compatibility however challenges current empirical understanding of wage and transport cost elasticities with population, and requires a scaling of the housing land profile that is different from the observed. Our results call for revisiting theories about land development and housing processes as well as the empirics of agglomeration benefits and transport costs.

中文摘要：
由于人们需要更好地理解城市致密化的挑战，城市特征与总人口的比例已成为一个重要的研究领域。然而，城市规模研究在很大程度上与城市内部结构脱节。相比之下，阿隆索的单中心模型为城市密度剖面提供了基于住宅选择的理论。然而，对于这些剖面如何与人口成比例保持沉默，从而阻止了实证规模研究以强有力的微观经济理论为基础。本文通过在阿隆索模型中引入土地、收入和运输成本的幂律来弥补这一差距。从这个扩展模型中，我们得出了均衡城市结构与欧洲城市土地规模和人口密度分布的最新实证结果相匹配的条件。我们发现，阿隆索模型在理论上与观察到的人口密度分布比例相符，并令人满意地代表了欧洲城市。然而，这种兼容性挑战了当前对工资和交通成本与人口弹性的实证理解，并要求对住房土地概况进行不同于观察到的缩放。我们的研究结果要求重新审视土地开发和住房过程的理论以及集聚效益和运输成本的实证。
