Abstract: As the increment stage of urban development gives way to the stock stage, urban update and enhancement have gradually replaced urban enlargement. Based on the renovation projects of old communities of C City and taking into consideration theories and field investigation, this study first analyzes the collaborative governance of the multiple subjects in renovation of a number of old communities, then proceeds to sum up the four major subjects involved and their inter-relations. The investigation identifies some problems–absence of relevant subject in the renovation, unbalanced power structure among the subjects and inadequacy of their collaboration–and analyzes the underlying reasons. Finally, the study suggests some measures regarding construction of multi-subject collaboration governance mechanism in renovation of old communities from three aspects: participation incentive mechanism, communication and collaboration mechanism and operation guarantee mechanism.

Key words: collaborative governance, renovation of old community, realization mechanism
