普通话能力对流动人口健康的影响:来自CGSS的经验证据

The Impact of Proficiency in Mandarin on Migrants’Health in China

流动人口健康是一个重要的社会和公共卫生问题.利用中国综合社会调查(CGSS2013)中的农民工样本数据,考察普通话能力对流动人口健康的影响及其群体间差异.研究发现,普通话能力与农民工健康呈正相关关系,即较好的普通话听辨和表达能力可以提高农民工身体健康的概率.同时,普通话能力的健康效应在农民工样本中存在着明显的异质性.在利用工具变量法克服了可能存在的内生性之后,上述结论依然稳健.发现和理解语言的健康效应,对于增强对语言经济社会效应的认识,对于语言扶贫、健康扶贫以及促进流动人口社会融入等都具有重要的意义.

Based on the micro-data of the China General Social Survey in 2013,this paper examines the impact of proficiency in Mandarin on health among migrant workers in China.We find that proficiency in Mandarin is positively associated with migrant workers’health.A higher level of Mandarin listening and speaking ability helps to increase the probability of being healthy for migrant workers.A further study shows that there is heterogeneity in the health effects of proficiency in Mandarin.After controlling for the possible endogeneity,the results are still robust.
