DELINEATING METROPOLITAN AREAS USING LAND PRICES*
提出一种利用土地价格中集聚经济成分来划定都市区的新方法，能内生识别中心并考虑次中心，实证显示该方法在人口密集区划出更少但更大的都市区，在稀疏区则划出更小的都市区。
ABSTRACT This paper proposes an approach to delineating metropolitan areas that is more general than the standard approaches in three respects: First, it uses the fraction of land prices attributable to economies of urban agglomeration instead of using commuting intensities as an indicator of economic integration between metropolitan centers and their hinterlands. Second, it identifies metropolitan centers endogenously instead of determining them exogenously. And third, it takes metropolitan subcenters explicitly into account. An empirical illustration is used to show that the approach tends to delineate fewer but larger metropolitan areas in densely populated regions, and smaller metropolitan areas in sparsely populated regions.
