How to Improve Collaboration in Sustainable Urban Community Renewal? An Evolutionary Game Model

Urban community renewal is an important direction for sustainable urban development in the era of building stock. Unlike traditional construction projects, the deeper involvement of residents in community renewal leads to more complex stakeholder relationships and new conflict-of-interest issues, requiring collaboration for the development of sustainable human settlements. Grounded in collaborative governance theory, this study constructed a tripartite evolutionary game model and employed simulations to analyze the evolutionary paths and key influencing factors to improve collaboration. The findings suggest that there are three main scenarios of urban community renewal: government-led, market-led, and multi-participation, and that the realization of sustainable collaboration is determined by the creation of collaborative advantages, the magnitude of speculative benefits for companies, and the regulatory costs incurred by the government. In conclusion, this study reveals the strategic choices and necessary conditions for each subject under different scenarios. It is necessary to improve the top-level design of the collaborative governance of urban community renewal, strengthen the construction of information sharing and feedback channels of urban community renewal, and establish the whole process supervision system of urban community renewal.
