Abstract: Time bank is a relay of love characterized by "service for service". This point-exchange-based voluntary service has become a new platform which encourages residents’ participation in community management and enhances mutual assistance in neighborhood. In community construction, while Lanjiang Subdistrict Time Banks encourages multiple-subject-driven management, resident-friendly activities and incentive mechanism for common people, "Lanjiang mode" lacks human support for effective operation and endogenous forces from social organizations. Phenomena like predominance of depositing rather than withdrawing score is increasingly worrying, while individual kindness-relied community support network has not yet been born. From three stages of self-organized agglomeration, self-organized order-keeping and self-organized promotion, time banks can take on the role of keeping regional communities together.

Key words: time bank, community construction, social work, community support, self-organization
