Impact of Urban Spatial Compactness on Carbon Emissions: Heterogeneity at the County Level in the Beijing–Tianjin–Hebei Area, China
Urban spatial compactness is crucial for reducing carbon emissions and promoting sustainable urban development. However, the potential of and variations in spatial compactness in county-level carbon reduction have been largely overlooked. Taking the county-level areas in the Beijing–Tianjin–Hebei (B...

| description | Urban spatial compactness is crucial for reducing carbon emissions and promoting sustainable urban development. However, the potential of and variations in spatial compactness in county-level carbon reduction have been largely overlooked. Taking the county-level areas in the Beijing–Tianjin–Hebei (BTH) region as an example, after reviewing the dimensions, scales, and pathways of the existing research, we quantifies the spatial compactness from 2005 to 2015 in terms of density, morphology, and function. The results reveal that, firstly, BTH county-level areas’ carbon emissions, both per land area (CO<sub>2</sub>/L) and per capita (CO<sub>2</sub>/P), have generally risen. Heterogeneity varied across spatial compactness indicators: urban density and functional compactness increased, while morphological compactness showed a minor fluctuation. Second, the correlations with CO<sub>2</sub>/L were stronger than those with CO<sub>2</sub>/P, ranking from urban density, functional compactness > morphological compactness. Additionally, the geographically and temporally weighted regression (GTWR) model revealed the spatial and temporal heterogeneity in the impact of spatial compactness on carbon emission intensity. The heterogeneity results provide insights into the mechanisms and general patterns of the differences in the factors influencing carbon emissions in four different types of county-level areas, namely, central, eastern, southern, and northwestern, offering policy guidance to promote the reductions in both CO<sub>2</sub>/L and CO<sub>2</sub>/P. This study is helpful for proposing urban spatial planning strategies for carbon reduction and formulating differentiated carbon reduction policies. |
