Study on rural poverty change and decomposition effect in Guangdong province

Based on 2000-2014 Guangdong rural income grouped data in five slices，by using the GQ model and the Beta model fitting the Lorenz curve and calculated the absolute poverty line and the relative poverty line’s poverty scale of rural residents in Guangdong respectively，the paper adopted three factors Shapley value decomposition method to analyze the impact of economic growth，income distribution and poverty line variation on poverty changes since entering the 21st century. The results showed that it was more reasonable to measure the poverty scale of Guangdong countryside by relative poverty line. Economic growth had been positive for poverty reduction from 2000 to 2014；Income distribution had different effect on poverty reduction in different periods，during 2000-2004， income distribution was not conducive to poverty reduction，during 2005-2014，the income distribution structure improved and played an positive role in poverty reduction. Poverty line variation had a negative effect on poverty reduction，price changes and the rising cost of living offset much of the improvement of poverty reduction brought by economic growth and income distribution structure improved，hindering the process of Guangdong rural poverty reduction. Thus，improving income distribution structure，maintaining the steady growth of economy and curbing inflation in Guangdong can play a promoting role in solving the relative poverty problem and achieving the goal of building a moderately prosperous society in all respects.
