| The citizenization of the migrant agricultural population is an important goal of accelerating the realization of economic and social development and comprehensively improving the quality of the new urbanization during the 14 th Five-Year Plan period.The willingness of migrant workers to migrate permanently is the premise of this process.In recent years,the Chinese government has repeatedly relaxed its urban hukou policy,but migrant workers’ willingness to make permanent migration in cities faces difficulties.The academic circle generally agrees that the urban public service should have the effect of improving the willingness of migrant workers to migrate permanently.In fact,the actual level of access to urban public services for migrant workers is not as expected.In this context,can urban public services still enhance the willingness of migrant workers to migrate permanently? If yes,what is the mechanism of urban public service to improve the willingness of migrant workers for permanent migration? The relative poverty hypothesis points out that improving the income relative poverty under the village residents as the reference system is the motivation for the floating population to make migration decisions.However,after entering the city,migrant workers may use urban residents as the new reference system to replace the original village reference system.The change of the reference frame may make the migrant workers present a multi-dimensional relative poverty state relative to the new reference object——urban residents,and then affect their urban permanent migration willingness.Based on this,this thesis uses the matching data of volumes C and D of China Migrants Dynamic Survey in 2017,selects the inflow urban residents as the reference frame,and explores the influence and function mechanism of urban public services on the permanent migration willingness of migrant workers based on the perspective of multi-dimensional relative poverty improvement.The study found that urban public services do have the effect of improving the willingness of migrant workers to migrate permanently.Mechanistic tests showed that,urban public service has improved the multi-dimensional relative poverty of migrant workers with urban residents as the reference system,and the improvement of the multi-dimensional relative poverty of migrant workers has enhanced their urban permanent migration willingness;From the specific dimensions,urban public services enhance permanent migration willingness of migrant workers mainly by improving relative poverty in health care dimensions.Although urban public services improve relative poverty in social security dimension and expenditure dimension,however,both relative poverty do not suppress permanent migration willingness of migrant workers.Relative poverty in education dimension suppresses permanent migration willingness of migrant workers,however,urban public services do not alleviate relative poverty in education dimension.The heterogeneity tests find that public services enhance permanent migration of migrant workers mainly through improving multi-dimensional relative poverty of residence permits,old generation,mobility within the province as well as for better education for children.This thesis believes that poverty situation of migrant workers different rights in the same city compared with urban residents should be improved as soon as possible,and different types of migrant workers should be treated in classification in order to accelerate new type of people-centered urbanization. |
