Table 3 Distribution characteristics of KDE curves of UCEE across the country and four regions.
From: Spatiotemporal evolution and convergence patterns of urban carbon emission efficiency in China
Type | Distribution location | Main peak shape | Ductility | Number of peaks |
|---|---|---|---|---|
Nationwide | move right | height increases width increases | right-skewed tail convergent ductility | unimodal |
Eastern China | move right | height increases width increases | right-skewed tail convergent ductility | unimodal |
Central China | move right | height increases width increases | right-skewed tail convergent ductility | unimodal |
Western China | move right | height increases width increases | right-skewed tail divergent ductility | bimodal multimodal |
Northeastern China | move left | height decreases width increases | right-skewed tail divergent ductility | unimodal bimodal |
