Abstract: With the overall victory in poverty alleviation, the implementation of relative poverty governance has become an important strategic choice at present for China to steadily advance the realization of the goal of common prosperity. Common prosperity is the goal orientation of the governance of relative poverty, while the governance of relative poverty is the premise means for common prosperity. Based on the data of the 2018 CFPS, this paper conducts a measurement with the A-F method. The findings show that the dimensional contribution rate of the multidimensional poverty index of the relatively poor households in China's rural areas in the order of high-to-low is education, living standard, health, labor capacity, medical insurance and housing. The number of relatively poor families suffering from poverty in more than 5 dimensions or a single dimension at the same time is relatively small, and more than 50% of the relatively poor families suffer from poverty in at least 3 dimensions at the same time. The result of the regional decomposition shows that both the incidence of multidimensional poverty and the severity of multidimensional poverty are the highest in the western region, followed by the eastern region, and the lowest is in the central region. The result of the income decomposition shows that the lower the income the household received, the higher the incidence of multi-dimensional poverty will be; and the more dimensions of poverty suffered, the more serious the degree of poverty.

Key words: relatively poor families, multidimensional poverty, poverty measurement
