Riding the Wave of Urban Growth in the Countryside: Spread, Backwash, or Stagnation?
研究城市增长对乡村地区的影响，区分扩散效应和回流效应，利用加拿大GIS数据库分析不同距离和社区规模下的乡村增长模式。
<i>The advisability of an urban-centered growth strategy to reap the benefits of urban agglomeration economies is much debated. Rural areas benefit when the growth “spreads” to the hinterlands, especially within daily commuting distance. Yet, in distant-peripheral locations, urban growth may create a “backwash” as households relocate to the urban center. This study examines spread vs. backwash, as separate from long-run, distance-from-urban-center trend effects, using a novel Canadian GIS database. The unique nation-wide approach yields a spread and backwash rural-growth topography that varies by distance from the urban center, by urban population vs. income growth, and by size of rural community.</i>
