| Comprehensively improving the popularity and quality of the national commonly-used language and script is an important measure to effectively link the achievements of poverty alleviation with rural vitalization.Taking the six counties along the China-Vietnam border in Guangxi as a sample,sorting out the framework of relative poverty and the anti-poverty promotion,analyzing the internal mechanism of Putonghua skills to alleviate relative poverty combined with the basic theory of poverty and the scope of language function and language economics,constructing a multi-dimensional relative poverty index system,using A-F method to calculate the different mandarin level of relative poverty incidence and multidimensional relative poverty index,and take the PSM matching method to explore the actual mitigation effect of relative poverty,and put forward the promotion suggestions under the management of relative poverty in the new period.First,from the theoretical perspective,the popularization is conducive to improving labor income and alleviate income poverty,optimizing the individual feasible ability and realizing substantive freedom;to improve the shackles of "occlusion" culture and enhancing the endogenous motivation.Second,from the empirical level,the probability of relative poverty in individuals with high Putonghua level is relatively lower,and the improvement of Putonghua ability has a certain probability to alleviate the relative poverty of individuals in income,education,health,information,social relations,ideological construction and other dimensions.In addition,the results of the heterogeneity analysis showed that the Putonghua skills improvement played different roles in different age and gender groups.Specifically,the relative poverty alleviation effect of Putonghua has not been fully played out in the elderly group and the female group.Third,the promotion policy should match the realities of poverty management and the realities of the region,focusing on key groups and taking targeted measures. |
