Spatial economics aims to explain why there are peaks and troughs in the spatial distribution of wealth and people, from the international and regional to the urban and local. The main task is to identify the microeconomic underpinnings of centripetal forces, which lead to the concentration of economic activities, and centrifugal forces, which bring about the dispersion of economic activities at the regional and urban levels. Transportation matters at both scales, but in a different way. The emphasis is on the interregional flows of goods and passenger trips at the regional level and on individual commuting at the urban level.

从空间经济学中学到什么？

空间经济学旨在解释从国际和地区到城市和地方的财富和人口的空间分布为何存在高峰和低谷。主要任务是查明导致经济活动集中的向心力的微观经济基础和导致区域和城市水平的经济活动分散的离心力。运输在两个方面都很重要，但方式不同。重点是区域一级的区域间货物流动和旅客旅行以及城市一级的个人通勤。
