What Can Be Learned from Spatial Economics?
解释财富和人口在空间上分布不均的原因，从国际到地方尺度，分析导致经济活动集中或分散的微观经济力量，并探讨交通在不同尺度下的不同作用。
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.
