Driving Forces of Urban Sprawl in China

Driving forces of urban sprawl in China are different from that in developed countries. Population growth, economic development, traffic and information technological development lead to rapid expansion of urban space. Lack of effective guidance and standardization of urban land expansion gives rise to low efficiency use of urban land, namely urban sprawl. Moreover, the root of urban sprawl in China is ascribed to the flaws of policy and institution. Therefore, the key point of urban sprawl control in China should be intensification of land use and perfection of policy and institution.
