The major victory in poverty alleviation has provided a strong guarantee for implementing the rural revitalization strategy and laid a solid foundation for achieving common prosperity for all.However,China has only solved the phenomenon of absolute poverty in a historical and phased way,and the focus of work in the next stage will shift to the alleviation and treatment of relative poverty.Therefore,setting the relative poverty standard and identifying the relative poor population are the primary problems to be solved.Government transfer payment is an important means to carry out poverty reduction work in the stage of absolute poverty in China.It has achieved remarkable results in reducing the incidence of poverty and improving the lives of poor people,and is also an important way to carry out relative poverty management in the future.Therefore,it is of great theoretical value and practical significance to study the impact of government transfer payments on poverty vulnerability from the perspective of relative poverty.Based on the fundamental goal of achieving common prosperity in China,this paper uses the 2018 Database of China Household Tracking Survey(CFPS)to study the setting of relative poverty standards,poverty vulnerability and the impact of government transfer payments on poverty vulnerability in China by dividing the samples into urban and rural areas、eastern,central and western regions.First of all,the relative poverty standard of this study is set based on the median income ratio method by referring to the existing relative poverty standards at home and abroad,and the FGT method is used to measure the scale of relative poverty in China.Secondly,based on the different relative poverty standards set,Vulnerability as Expected Poverty(VEP)method is used to measure the vulnerability to poverty of families,and the proportion of families with vulnerability to poverty and the relationship between relative poverty and vulnerability to poverty are analyzed.Finally,based on the specific values of poverty vulnerability of each sample family,the improvement effect of government transfer payment on poverty vulnerability was analyzed and robustness test was conducted by using baseline regression and propensity score matching method.The findings are as follows: Firstly,if the relative poverty standard is defined according to the median per capita income of the total sample households,the relative poverty phenomenon is concentrated in rural areas,central and western regions;If the relative poverty standard is determined according to the sub-sample,the identification of the relative poor population will be more accurate,and the distribution of the poor population will be more uniform and reasonable.Compared with the actual incidence of relative poverty in the EU member states,it is found that China is currently facing a relatively severe relative poverty situation,and the relative poverty situation in urban and eastern areas is more serious.Secondly,relative poverty and poverty vulnerability are intertwined,and the vulnerability of poverty is higher in urban and eastern areas.Thirdly,government transfer payments significantly reduce the vulnerability of households to poverty,but the impact gradually weakens with the increase of relative poverty standards.Fourthly,under the same relative poverty standard,government transfer payments have a greater impact on the vulnerability of rural households to poverty than urban ones.The degree of impact on poverty vulnerability of families in the western region is greater than that in central region,and the central region is greater than the eastern region.Based on the research results,this paper proposes to set relative poverty standards according to urban and rural areas,and focusing on solving regional development gaps and internal inequality;Establish and improve the dynamic monitoring and exit mechanism of relative poverty returning to poverty,and provide differentiated assistance according to the specific reasons for low-income groups to become poor and return to poverty;Improve the government transfer payment assistance mechanism,improve targeting accuracy and targeting efficiency,expand the coverage and support of government transfer payments,formulate clear cashing conditions,and provide precise and comprehensive assistance to special groups. |
