| The comprehensive victory of poverty eradication has eliminated absolute poverty,but the removal of poverty is not the end of the anti-poverty process in China,and the problem of relative poverty still persists.As relative poverty is multidimensional and complex,its poverty manifestation is not only reflected in the income dimension,but also in the lack of social resources such as housing,education,medical care and social security.Meanwhile,during the period of precise poverty alleviation and poverty eradication,China has been carrying out long-term public service provision with education,medical care,social security and employment as the main contents,and vigorously promoting the equalization of basic public services.The 19 th Party Congress clearly proposed the implementation of the rural revitalization strategy,and the 20 th National Congress of the CPC further proposed to comprehensively promote the rural revitalization strategy and comprehensively build a modern socialist country,and the No.1 Document of the Central Government in 2023 further emphasized the "three rural issues".In this development context,alleviating multidimensional relative poverty becomes the main task of anti-poverty in the new era,and strengthening public service supply becomes an important measure to alleviate multidimensional relative poverty.The poverty characteristics of multidimensional relative poverty correspond to the content of public service provision.Based on the extension of sustainable livelihood theory,this paper considers public service provision as an exogenous shock in the framework of sustainable livelihood,explores the impact of public service provision on the livelihood capital of multidimensional relatively poor households,and clarifies the inner mechanism of public service provision in alleviating multidimensional relative poverty at the theoretical level.At the same time,the paper introduces five types of livelihood capital and uses the A-F double-bounded approach to measure the incidence of multidimensional relative poverty and to separate the contribution of indicators.The paper designs indicators for the comprehensive level of public service provision,constructs a fixed-effects model to empirically test the impact of public service provision on alleviating multidimensional relative poverty,and divides the research sample into four regions according to different levels of economic development for heterogeneity analysis to study the regional heterogeneity of public service provision in alleviating multidimensional relative poverty in regions with different levels of economic development.This paper concludes the following: First,human capital deficiency has a high contribution to the occurrence of multidimensional relative poverty,and the alleviation of multidimensional relative poverty needs to focus on the continuous accumulation of human capital.Second,public service provision can effectively alleviate multidimensional relative poverty by increasing various types of livelihood capital of multidimensional relatively poor groups,optimizing their livelihood strategies,and effectively improving the vulnerability of the external environment.Third,the effect of public service provision in alleviating multidimensional relative poverty is regionally heterogeneous across different levels of economic development,and the policy design of public service provision needs to be adapted to the regional level of economic development.Based on the above findings,this paper proposes policy recommendations for optimizing public service provision policies to alleviate multidimensional relative poverty. |
