Table 1. SDG 1 China’s district and county localization indicator system.
Table 2. Localized SDG 1 index weight for districts and counties.
Figure 4. SDG 1 evaluation value ranking of some districts and counties in China in 2014. (a) and (b) are calculated based on SDG 1 China’s district and county localization indicator system proposed in this study and by Wang et al. (Citation2021a) research, respectively. If the rank of the district/county is lower, it means that the SDG 1 evaluation value of the district/county is lower.
