| Summary: | 碩士 === 逢甲大學 === 都市計畫所 === 97 === Urban ‘’Sprawl’’, leading to urban development was not sustainable, so A great deal of literature has been generated by the academic concerns. Comprehensive look at patterns of development can be divided into leapfrog development, commercial strip development, large expanses of low-density development, single-use development, suburbanization development (Ewing, 1997; Gillham, 2002; Tsai, 2005).
Over the past many studies have pointed out that Taiwan''s metropolitan areas also have the phenomenon of Urban Sprawl. However, household size reduction caused population increased, and the number of household also increased in central city, which led to the phenomenon of urban sprawl, and population decreased and the number of household increased in central city, which of urban sprawl patterns indicated the demand of housing units in central city is increasing by failure of housing supply led to urban sprawl. However, this concept has seldom been applied in analyzing, quantifying urban sprawl.
The main results of this study is supply and demand of housing units to observe Taiwan''s metropolitan areas and the phenomenon of urban sprawl shows that the sprawl of the metropolitan areas of the driving forces of supply and demand for housing units. To the types of dynamic transformation of urban sprawl/compactness of view, shrinking household size led to urban sprawl in Taiwan’s metropolitan areas. Population decline, the number of household is still increasing which of urban sprawl patterns was caused by shrinking household size and failure of housing supply. To pushing/Pulling force between central city and outskirt in metropolitan areas of view, supply and demand of housing units led to urban sprawl in Taiwan’s metropolitan areas, met housing units demand in central city will lead to inbound intra-metropolitan migration, unmet housing units demand in central city will lead to outbound intra-metropolitan migration. The pushing/pulling force will be reinforced by improving the level of accessibility for between central city and outskirt.
