Abstract: From the perspective of third-party evaluators, this paper takes the professional practice of W organization's participation in the green governance of urban communities in H district as a case study. While critically reflecting on the previous theories, the paper constructs an analytical perspective of agents and space production based on the theory of "interests alignment and organizational action", so as to explore in depth the micro-mechanism and the inherent operating logic of social organizations' participation in the practices of community green governance. The study finds that in the practice of promoting community green governance, while confronted with the governance scenarios of weak community participation, limited motivation and community relationship alienation under the strong administrative governance, W organization actively promotes down-top, resident-led community green governance actions from the three aspects of "cognition", "empowerment" and "community building", thus directly promoting the restructuring of community elements, the reshaping of community public space, the cultivation of community spirit, and the reconstruction of social networks. In this way participation motivation of the agents has been shifted from the self-interested participation in the interest alignment mode to the altruistic governance of the organizational action mode, thus truly forming a community-based green governance community.

Key words: community green governance, agents, public space production, a community for communal life
