THE EFFECT OF TRANSPORTATION SUBSIDIES ON URBAN SPRAWL*
通过理论和实证分析，研究交通补贴对城市空间扩张的影响，发现公交补贴使城市面积缩小，而汽车补贴则使其扩大但增速递减。
ABSTRACT This paper provides theoretical and empirical analyses of the effect of transportation subsidies on urban sprawl in a two‐mode urban spatial model. Comparative static analysis shows, among other things, that the urban area contracts with a public transit subsidy but expands with an auto subsidy. The paper provides the first empirical test of these hypotheses and finds that the spatial size of the urbanized area shrinks with an increase in transit subsidies but increases at a decreasing rate with auto subsidies.
