Abstract: Rural public space governance is a key task for the improvement of the living environment, and it is also an important starting point for realizing rural revitalization. The difficulty of public space governance mainly lies in the dilemma of collective action caused by “zero-sum” space. It was found that, the village of Jinjiang City used clan power to guide villagers to recognize goals, grid management to reduce the scale of collective action, and villagers’ preferences for selective incentives, so as to promote villages to achieve collective action goals, so that “zero-sum space” evolves into “positive sum space” . The experience of “zero-sum space” improvement in rural areas of Jinjiang City not only provided reference for similar public space governance in other villages, but also provided useful enlightenment for the formation of long-term mechanisms to promote the achievement of collective action goals through institutional design in rural grassroots governance in the future.
