Social　network　analysis　is　one　of　the　most　important　instruments　to　study　collective　decision　making　by　assessing　personal　support　networks　in　whole　communities.　Although　cost-benefit　analysis　is　a　fundamental　method　for　analysing　decision　making　in　human　migration,　the　decisions　made　by　villagers　about　rural-urban　migration　are　also　directly　or　indirectly　affected　by　the　ties　of　an　ego　(villager)　connected　to　an　alter　(other　villager),　the　whole　network　structure　and　the　attribute　characteristic　of　both　ego　and　alter.　The　aim　of　this　research,　based　on　a　case　study,　is　to　draw　attention　to　these　support　network　processes.　An　empirical　study　considering　rural-urban　migration　in　China　has　been　undertaken　to　discuss　and　explore　the　relevance　of　social　network　analysis　associated　for　migration　decision　making　under　the　government＇s　favourable　migration　policy,　where　cost-benefit　considerations　have　a　non-significant　effect　on　villagers＇　decision　process.　Copyright　©　2013　Inderscience　Enterprises　Ltd.
