Rural environmental governance has entered a new stage, in which the establishment of long-term and effective mechanisms has become a key objective. In rural social fields, local governments, village organizations, and villagers serve as major actors. It is necessary to shift from the previous government-dominated governance model to a collaborative participation model involving all three actors. The case of the Eco-Laundry House in Hexi Town, central Zhejiang Province, effectively illustrates how local governments, village organizations, and villagers establish a cooperative governance mechanism in rural social fields, promoting the construction of long-term mechanisms for rural environmental governance. By analyzing both the practice and underlying logic of collaborative governance in this case, the study deepens our understanding of the cooperative relationships among actors in current rural social fields. Through consultative dialogue based on equality and mutual trust among actors, their interests and demands are realized, ultimately achieving the objectives of effective rural governance and ecologically livable environments. Meanwhile, based on empirical research, this study theorizes how actors with unequal status can nevertheless build equal and trust-based cooperative mechanisms in the rural field, further enriching the theoretical research on cooperative governance.
