This report firstly analyzes the current situation and mechanism of the collaborative governance in the Beijing-Tianjin-Hebei Region. Secondly，based on the results of simulation experiment，it is concluded that the multi-agent network collaborative governance mode is the most suitable mode for the collaborative governance in the Beijing-Tianjin-Hebei Region. Thirdly，starting from the agent，network，interaction and mechanism，this report constructs the multi-agent network collaborative governance mode in the Beijing-Tianjin-Hebei Region，according to the analytical framework of “multi-agent，network structure，interactive relationship，collaborative mechanism”. Then，this report analyzes the difficulties in multi-agent collaboration，in the shaping process of the network structure，in the interaction between multi-agent，and in the construction of collaborative governance mechanism in the Beijing-Tianjin-Hebei Region. Finally，this report puts forward the path and a series of policy recommendations to achieve the multi-agent network collaborative governance mode in the Beijing-Tianjin-Hebei Region.
