中国农民工社会网络的凝聚子群结构分析

本文采用深圳农民工调查的整体网络数据，分析了农民工社会支持网（包括实际支持网、情感支持网、社会交往支持网）和社会讨论网（包括婚姻讨论网、生育讨论网、避孕讨论网和养老讨论网）的凝聚子群结构。研究发现，农民工社会网络中普遍存在子群现象，且子群之间有较大程度的重叠。农民工社会支持网和社会讨论网的子群重叠结构既有利于农民工群体的城市社区融合，也有利于新的婚育、养老文化的传播。

An Analysis of the Cohesive Subgroup Structures in the Social Networks of the Rural-Urban Migrants in China

Using the entire data set from Shenzhen Rural Urban Migrants Survey in 2005， this paper analyzes the cohesive subgroup structures in the rural urban migrants' social support networks （including instrumental， emotional， and social contact support networks） and social discussion networks （including marriage， childbearing， contraception， and old age support networks）. The results indicate that the phenomenon of subgroups is widely exhibited in these migrants' social networks， and such subgroups overlap to a great extent. The overlapped subgroup structures in the social support and social discussion networks are helpful not only to the migrants' social integration into the urban communities， but also to the expansion of the new culture in regards to marriage， child bearing， and old age support.
