基于2017年中国流动人口动态监测调查数据，从社会网络的新生关系网络和社会活动参与两个方面，考察社会网络对农民工城市定居意愿的影响效应及内在机理。研究发现：新生关系网络和社会活动参与均对农民工城市定居意愿有显著正向影响；社会网络作为农民工联系迁入地居民的纽带，能够通过工资收入和身份认同两个方面间接提升农民工城市定居意愿；异质性检验发现，新生关系网络、社会活动参与对农民工城市定居意愿的影响表现在流动年限差异、教育年限差异以及性别差异，即这些个体特征在社会网络之间产生交互效应。应建立良好的社区管理体系，规范用工单位雇员最低工资，促进不同类型公共服务供给，发挥不同群体之间的带动作用，以提升农民工城市定居意愿。

Based on the data of China Migrants Dynamic Survey (CMDS) in 2017, the paper examines the impact of social networks on migrant workers' urban settlement intention and its internal mechanism from the two aspects: the relationship network of new generation farmers and social activity participation. The research shows that the new relationship network of new generation farmers and social activity participation have a significantly positive impact on migrant workers' urban settlement willingness. As the link between migrant workers and local residents in the immigration area, social network can indirectly enhance migrant workers' urban settlement intention through wage income and identity. The heterogeneity test finds that the influence of new generation farmers’ relationship network and social activity participation on migrant workers' urban settlement willingness is manifested in the differences in the experience of mobility, education and gender, namely, these individual characteristics have an interactive effect between social networks. It is advisable to establish a good community management system, standardize the minimum wage of employees in the employing units, promote the supply of different types of public services and play a leading role among different groups to enhance migrant workers' urban settlement willingness.
