The renovation of old urban residential areas is and will continue to be an important part of urban renewal in China. The renovation of existing old urban residential areas focuses more on the physical level of renovation and pays insufficient attention to the improvement of collaborative community governance. However, collaborative community governance is the key to sustainable renovation. This study aims to explore the formation mechanism of multiple subjects’ collaborative governance in the renovation of old urban residential areas. A general collaborative governance theoretical framework was adopted and adjusted by innovatively introducing the improvement of collaborative community governance in old urban residential areas as an important variable in collaborative results. Data were collected through 853 questionnaires in 16 provinces across China and analyzed using Structural Equation Modeling. Data analysis reveals the following conclusions: (1) institution design and the collaborative process have significant positive impacts on collaborative results, while facilitative leadership has a negative impact; (2) the collaborative process is an important mediating variable on collaborative results; (3) government departments’ and residents’ self-governing organizations play important roles in improving collaborative community governance. Face-to-face dialogue and consultation, information disclosure and transparency, and reaching an intermediate consensus are important mediator variables. The research results provide theoretical support and practical suggestions for promoting the improvement of multiple-subject collaboration through old urban residential area renovation.

The renovation of dilapidated housing has become a focal point of social concern. However, traditional approaches—such as repair and reinforcement or unified demolition and relocation—face bottlenecks that hinder sustainability. There is an urgent need to explore new models for addressing the risks posed by dilapidated residential buildings. In recent years, multiple regions have explored the “original demolition and original reconstruction” approach for dilapidated housing. For instance, Zhejiang Province introduced the “Resident-led Renewal” model, sparking widespread attention and discussion. This model is characterized by residents serving as the primary investors. However, the manner in which stakeholders—particularly residents—collaborate in governance and interact during the renovation process under this model remains unclear. Using the Zhegong New Village original demolition and reconstruction project as a case study, this paper employs social network analysis to construct relational networks encompassing information, trust, consultation, and support. It quantitatively reveals the characteristics of social networks among stakeholders and their interactive practices within the Resident-led Renewal model. Findings reveal that in this case, “Resident-led Renewal” primarily manifested through residents serving as principal investors and establishing a Self-Driven Renewal Committee to submit the original demolition and reconstruction application on behalf of residents to local authorities. In stakeholder interactions, the government and community neighborhood committees play a coordinating role in the renovation process. However, resident organizations and residents themselves ranked lower in metrics such as reciprocity and degree centrality, indicating their limited influence during the renovation process. To alleviate the pressure of the government’s excessive involvement and enhance resident participation in the “original demolition and original reconstruction” process, efforts should focus on: raising residents’ awareness and capacity for participation; ensuring accessible channels for resident involvement; clarifying the rights and responsibilities of all stakeholders; and establishing a standardized approval process for “original demolition and original reconstruction” projects. This approach would realize a “Resident-led Renewal” model characterized by government guidance and resident participation.
