Abstract: Using case study and interview, this article, with GaoTian Sub district of Weihai city as an example, analyzes the transformation of citizen participation in community governance under collective property rights reform. It finds that the collective property rights reform has reconstructed the right relationship among farmers, collective organizations and governments, reshaped the rural community organizations and their power structure, expanded the space for citizen participation, stimulated the interests requirement of citizens, improved the efficiency of resource allocation. The mobilized, implemented, formalized and unconventional interest-driven participation has substantially changed into a diversified, deep-seated and effective multi-dimensional organizational participation. For problems due to lack of continuous supervision mechanism, cost and efficiency, and institutional flaw in citizen participation, it is necessary to further strengthen the mechanism construction and follow-up supervision, properly balance the cost and output efficiency of participation, and improve the relevant institutional construction and legalization.
