Formation of Migrant Networks
通过调查米兰的斯里兰卡移民，首次直接揭示了移民社会网络的内部结构，发现网络形成模式因移民个体和网络功能（如住宿、信贷、找工作）而异。
Abstract In this paper, we provide the first direct evidence on the internal structure of the migrant social network. By using a purposely designed survey on Sri Lankan immigrants living in Milan, we show that the pattern of within‐group link formation is heterogeneous across immigrants, and differentiated according to the network function (i.e., accommodation, credit, job‐finding). We find that migrants tend to interact with co‐nationals who come from nearby localities at origin, while the time of arrival has a U‐shaped effect. Once the link is formed, material support is provided mainly to relatives, while early migrant fellows are helpful for job‐finding.
