The results of herdsmen’s collective development in Tibet derive from two interrelated stages:the transfer of public resources to pastoral villages,and the transformation of public resources into herdsmen’s endogenous development ability.Based on the analysis framework of “systemlife”,this paper investigates the phenomenon of herdsmen’s collective development in Ali district G county.It is found that the herdsmen’s collective development is essentially the result of “interactive co-governance” between local government and herdsmen’s society.The local government strongly embeds itself into herdsmen’s society through the selection of village cadres and provision of policy projects,and promotes the orderly changes of herdsmen’s society within the collective framework on the basis of respect for the livelihood mode of the pastoral areas.The village collective takes over the government public resources,and adopts the flexible integration means such as bonding through friendliness and connection through interests.It guides the herdsmen’s collective development from the “system” form to the standardized “entity” form,and effectively realizes the village public reproduction.In the process of herdsmen’s collective development,the continuous interaction between system and life enhances the herdsmen’s endogenous development capability.The herdsmen see the possibility of solving their own survival crisis,and the shared interests arouse the sense of trust and belonging to the collective,thus contributing to the virtuous cycle of the herdsmen’s collective development.
