社会网络对农民工同乡聚居的影响研究

Study on the Effect of Social Network on Homeplace-based Settlement of Rural-urban Migrant Population

以亲缘、地缘为纽带的社会网络是农民工传递就业信息和实现就业的重要渠道。借助社会网络实现就业会如何影响农民工的聚居选择呢?通过构建理论模型和实证分析,本文对上述问题在理论和实证层面进行了研究。首先,本文构建了一个社会网络内生化的劳动力两区域均衡模型,对大城市乡城流动人口同乡聚居形成的微观机制进行了推演分析。理论模型表明,借助于社会网络就职会使农民工倾向于选择与同乡而非本地人聚居。其次,采用我国乡城流动人口数据(RUMiC)和国家卫计委中国流动人口社会融合调查数据进行了实证分析。研究发现,借助于社会网络就职的农民工倾向于选择同乡聚居而非与本地人聚居,而农民工的同乡聚居不利于其融入城市及社会融合。利用CMP方法处理了模型潜在的内生性问题及采用倾向得分匹配方法处理了样本选择性偏误问题之后,结果依然稳健。

Social network based on kinship and geographic ties has become an important channel for rural-urban migrant population to transmit information and achieve employment.How will it affect migrant workers’choice of settlement when rural-urban migrant population achieve employment through social network?By building theoretical model and making empirical analysis,the aforementioned problems are studied from the theoretical and empirical level.By building a theoretical model of labor migration on interregional equilibrium,this paper deduces and analyses the micro-mechanism of the formation of the homeplace-based settlement in big cities.Firstly,analysis of theoretical model indicates that employment through social networks will make rural-urban migrant population tend to choose to live with their fellow townsman rather than local people.Secondly,Using data of Rural-Urban Migration in China(RUMiC)and survey data of social integration of migrant population in China by the National Health and Family Planning Commission,this paper makes an empirical analysis.The study finds that rural-urban migrant population who achieve employment through social networks tend to choose to live with their fellow townsman rather than local people,while this behavior of settlement is not conducive for them to integrate into the city.The results are still robust,after using CMP method to deal with endogeneity and propensity score matching method to deal with sample selection errors.
