This lecture investigates micro as well as macro mechanisms facilitating the development of communitarian governance based on the assumption of most social actors with value of strong reciprocity. It also emphasizes that value of strong reciprocity is socially constructed and communitarian governance is established and revised under different socio-historical contexts. In addition to market and hierarchy, communitarian governance is the third way to regulate social relationships in a particular society. Facing serious problems of the development of capitalism and representative democracy in contemporary society, communitarian governance provides an significant theoretical base to design innovative alternatives under current economic and political institutions. To link communitarian governance and social innovation, this lecture demonstrates possibilities of integrating theoretical thinking and social practices.
