Under the background of rural revitalization and development, the collective presence, value recognition, and action choices of villagers towards rural public welfare undertakings directly affect the actual effectiveness of various project constructions. With the social changes, rural communities are showing a trend of loose development, and the atomization and dissociation of individual villagers are not conducive to the continuous promotion of rural public welfare construction. With the application of digital technology, village WeChat groups have important value in breaking down time and space barriers, shaping value consensus, and aggregating collective action. Through the reorganization of participating subjects, awareness, and actions, the application of village WeChat groups promotes the extension of participation space in rural public welfare construction.
