The effects of China's poverty eradication program on sustainability and inequality

Poverty eradication is the first goal on the United Nations' list of 17 Sustainable Development Goals (SDGs). However, the relationships between poverty eradication and the other SDGs remain unclear, and thus current knowledge is insufficient to support the synergized achievement of the SDGs. China eliminated extreme poverty in 2021, and thus in this study, we analyzed the variations in sustainability and equality related to the environment and the provision of public services in China during the poverty eradication program from 2010 to 2020. We combined statistical data, point of interest data, and environmental monitoring and remote sensing data to evaluate progress in China's 832 poverty-stricken counties. The results showed that the mean values of environmental and public service sustainability indicators improved from 2010 to 2020. In addition, the mean Theil index value decreased from 0.46 to 0.35 during this period, implying a reduction in inequality. Inequality between poverty-stricken and non-poverty-stricken areas accounted for 9.3% of overall inequality among the counties in 2010, and this had decreased to 7.7% in 2020. However, unbalanced regional investment resulted in increased gaps between poverty-stricken and non-poverty-stricken counties in relation to education and health care. Overall, 15% of the population and 54.8% of the land area in poverty-stricken counties experienced both a loss of their advantage in terms of environmental quality compared with non-poverty-stricken counties and greater lags in the provision of public services. Linear estimation showed that investment in poverty-stricken counties should be increased by 226.2 and 72.0% in relation to education and health care, respectively, to eliminate these inequalities.
