In essence，to promote the modernization of urban social governance system and governance capacity is to prevent and control social risks and to maintain social order and stability. Dispute is a form of social interaction and social relations，but it is also a main source of social risks. The dynamic monitoring of disputes is mainly designed to gauge the potential risks and the dynamic trends of contradictions and disputes in society. On that basis，a social “safety valve” mechanism is established，which is aimed to alleviate the pressure of social conflicts on the one hand，and to play an early-warning role for grave social risks on the other. Based on the investigation and monitoring，the grass-roots disputes and their solutions in Beijing reveal a pattern of coexisting diversification and authority，discovering no prominent indicators of social risks. This paper mainly focuses on monitoring and effectively resolving disputes，better guiding public opinion，establishing a “safety valve” mechanism，promoting social equity，and enhancing the construction of a society of mutual trust, etc, to maintain order and stability in Beijing.
