Framework of New Poverty Decomposition: An Application to the Evolution of Income Distribution

Ending poverty in all its forms is the first of 17 sustainable development goals (SDGs) 2030 Agenda for Sustainable Development. Therefore, it great significance to study context development. At present, effect income growth on reduction becoming less evident, whereas inhabitant heterogeneity increasingly significant China. Based original two-dimensional decomposition and redistribution, this introduces decompose rural China from three dimensions. It decomposes change distribution into mean, variance, residual effects using counterfactual analysis. Then, Foster–Greer–Thorbecke index China’s under different line. In addition, paper employs mathematical statistics analyze poverty’s growth, dispersion, heterogeneity. This finds that three-dimensional method can measure trajectory trend more precisely comprehensively. Moreover, found contradiction between economic regression due fact alleviation discrete have asymmetrical characteristics, heterogeneous symmetrical characteristics; is, insufficient compensate deepening brought about by widening gap, plays an important role. prevent residents falling back after being lifted out it, we must reduce gap. residents’ ability their own be strengthened.
