Abstract: As the focus of community services and resources investment is increasingly directed to the grassroots, the construction of community life circles and community service facilities has been vigorously promoted in many Chinese cities. As the existing researches and practice mainly focus on plan compilation, index study and building construction, it has exposed many problems in the planning implementation and management operations. As an important part of the community life circle, the community complex is facing major challenges from “graphic integration” to “implementation integration” of community services. This paper takes community complex as the research object. Based on the case study in Beijing, Shanghai, Chengdu, Suzhou and other cities, and the methods of field survey, special symposium, questionnaire survey, and individual in-depth interview, as well as theoretical analysis of community life circle planning and holistic governance, this research summarizes the main fragmentation dilemmas and major challenges in the planning, construction and management process of community complex, and puts forward relative optimization strategies from the perspective of integration governance, including optimization of precise design control standards, establishment of interdepartmental and full-cycle coordination mechanism, and improvement of joint governance and cooperation mechanism.
