农民工小团体现象的探测与分析：基于社会支持网络的研究

本文利用2005年对深圳市农民工的调查数据，应用N G算法，探测到农民工社会支持网络中的小团体现象，并通过对其数目、规模及内聚程度的分析，探讨了亲缘、地缘关系在小团体现象中的角色问题。本研究发现，农民工社会支持网络具有明显的小团体现象，不同性别和不同职业构成的农民工社会支持网的团体化程度存在差异，实际支持网、情感支持网和社交支持网等三类网络的团体化程度也存在差异。混合性别网络的小团体的内聚程度低于单一性别网络的小团体的内聚程度，加工业农民工小团体的内聚力差异程度较大，而建筑业农民工小团体的内聚程度则普遍较高。加工业农民工的业缘关系是小团体形成的重要纽带，建筑业农民工的小团体以地缘关系为主，但业缘关系的作用开始凸显。

An Exploration and Analysis of the Sub-Group Structures Among Rural-Urban Migrant Workers: Based on the Study of Social Support Networks

Applying the Newman Girvan algorithm to the data from “Shenzhen Rural Urban Migrants Survey” in 2005， this study identified the sub groups in the rural urban migrant workers’ social support networks， analyzed their number， size， and cohesiveness， and discussed the roles of occupational ties， lood bonds and location bonds in these sub groups. The current study obtained the following findings: Rural urban migrant worker’s social support networks were clearly characterized of their sub grouping； the cohesiveness of their social support networks varied by sex and occupations； there were significant differences in the cohesiveness between the tangible， the emotional， and the social networks； mixed sex networks showed lower cohesiveness than single sex networks； manufacture workers’ groups varied more in cohesiveness， whereas construction workers commonly formed more coherent groups； occupational ties played an important role in bonding manufacture workers， whereas location was the major bond to connect construction workers although there were signs for the role of their occupational ties.
