Abstract: As a key focus of consolidating and expanding the achievements of poverty alleviation and effectively connecting them with rural revitalization, poverty eradication households should be given special attention. Based on the field survey data from 1283 poverty eradication households in a western province, this paper uses non-parametric statistics and propensity score matching (PSM) method to analyze the mechanism and the differences in the effects of various basic public services affecting the income of poverty eradication households. The findings show that: first, the basic public education and the basic labor employment can promote the increase of household wage income through human capital accumulation, and the income increase effect of the basic public education is stronger than that of the basic labor employment. Second, the basic social insurance and the basic social services have a positive impact on household transfer income and play a role in narrowing the income gap through redistribution, and the role of the basic social services is significantly greater than that of the basic social insurance. Third, the employment skills training of the basic labor employment and the renovation of dilapidated houses of the basic housing security services have a positive impact on household operating income by enhancing entrepreneurial ability and improving entrepreneurial conditions, and the income increase effect of the employment skills training is more prominent. In addition, the income-enhancing effects of the basic employment services show heterogeneity in different income types and householders’ education levels. The above research provides new insights for further optimizing and improving the basic public service policies with the goal of common prosperity.
