Research And Application Of Regional Poverty Line Measurement Method Considering Regional Income Gap

In November 2013,General Secretary Xi Jinping made an important instruction for ?seeking truth from facts,adapting to local conditions,classifying guidance,and precision poverty alleviation? for the first time during his visit to Hunan Xiangxi.At present,China's poverty standard is based on the constant price of rural residents' per capita net income of 2,300 yuan in 2011,and is adjusted year by year according to changes in the price index.Such a unified poverty standard does not take into account the income gap between our regions.At present,China's poverty standards are still based on income indicators.Therefore,the regional income gap is a factor that cannot be ignored in setting poverty lines and achieving accurate poverty alleviation.The measurement of the absolute poverty line in the study area is of great significance for the identification of the poor in China.The purpose of this paper is to measure the regional poverty line based on the regional income gap and the official poverty line of 2,800 yuan in 2015.First calculate the regional income gap.To this end,this paper introduces Amartya Sen's theoretical framework of feasibility ability.People with the same feasibility can get the same opportunities and freedoms from the resources owned by individuals.This paper believes that the real income gap between regions should be feasible.The income gap between people with the same ability.In this paper,the provincial-level regions are clustered according to the disposable income of rural residents in each province in 2015,and the income gap between regions is calculated.Firstly,the fuzzy set method is used to measure the feasibility of residents.Secondly,the membership degree of the four dimensions of feasibility ability and the indicators of living conditions such as clothing expenditure,food expenditure,and family-owned living goods are used as matching estimators.The propensity score matching method is used to investigate the income ratio of rural residents with the same feasibility among regions,so as to represent the ?real income gap? of rural residents in different regions.When considering the adjustment of the poverty line,only the income gap of 20% of the lowest income is selected to calculate the adjustment coefficient,and the income poverty line of China is adjusted according to the adjustment coefficient.The empirical results show that the feasibility of residents in different regions is significantly different.After the control feasibility is the same,the income gap between the residents in the region shows different characteristics as the income changes.When income is low,residents in different regions show lower income ratios and smaller incomes.As incomes increase,the absolute level of income ratio increases and the variation increases.When the poverty line of the regional areas 2 and 3 is set at the national average level of 2,800 yuan,the poverty line of the area 1 should be 4,879 yuan.After comparison,the results obtained in this paper are less deviated from the setting results of the national low-income line,which guarantees the credibility of the results.
