Abstract: Improving the social governance community system is proposed during the Fifth Plenary Session of the 19th Central Committee of the Communist Party of China (CPC). As an extension of the social governance community, the community plays an important role in implementing the requirement of the Fifth Plenary Session of the 19th CPC Central Committee. Based on the Marxist community thought and constructivism theory, this paper combines the community governance case to study the construction and improvement strategy of community under the governance requirements of the new era, from such three dimensions as consensus, action and structure. Our research shows that: community consciousness comes from the recognition, cohesion and guidance of community values, and emphasizes the responsibilities and obligations of community construction; community actions involve the formation of consensus action goals and the efficiency of integration, including community space resource integration and organizational integration; community governance structure is the transformation of the relationship between community subjects from tree-like separation to network-like connection in the process of consensus and action.
