Urban, Urban Morphology and Residents' Carbon Emission——A Study Based on Compact Cities Form
The residents' life carbon emission is not only affected by the internal spatial factors, like population density, public transport, land use structures and green system, but also further affected by the external spatial structure of urban systems. Therefore, we test the theories by an empirical study using panel data of 110 prefecture cities among 14 compliant urban agglomerations in China from 2006 to 2012. We find that, without considering the external spatial structure, most of the spatial factors fail to lower the carbon emissions completely as expected, except the fixed land use. If we take the external spatial structure into account, namely, the structure of city groups develops from "absolutely concentrated" to "relatively decentralized", urban population density, public transport and green system start to release regulation effect on residents' life carbon emission, which varies from the different capacity of developing "Low-carbon City".
