摘要：A residential location model derived from urban economics is combined with the geometry of a
multifractal Sierpinski carpet to represent and model a metropolitan area. This area is made up
of a system of built-up patches hierarchically organised around a city centre, and green areas
arranged in an inverse hierarchical order (large open-spaces in the periphery). An analytical
solution is obtained by using a specific geographic coding system for computing distances. The
values of the parameters used in the model are based on the French medium sized metropolitan
areas; a realistic benchmark is proposed and comparative-statics simulations are performed. The
results show that the French peri-urbanisation process (which took place from 1970 onward)
can be explained by an increase in income and a reduction in transport costs. Nevertheless,
changes in household preferences, in particular an increased taste for open spaces, can also
contribute to urban sprawl by making the gradient of land rents less steep and by making
peripheral household locations more desirable.
