In order to improve the living environment and meet the daily needs of residents, the Chinese government is vigorously promoting the policy of old community renovation, which is closely related to the life quality and happiness of the residents. However, conflicts often occur between residents and contractors in the construction stage of old community renovation projects as a result of failing to satisfy residents’ demands. This paper uses evolutionary game theory to explore this issue. An evolutionary game model between contractor and resident is established, and then nine different strategy evolution scenarios are derived based on it. Numerical simulation is conducted to analyze the influencing factors of conflict between resident and contractor in the construction stage. It is found that construction cost, reputation, and loss caused by resident’s protest are important factors for the contractor to consider resident’s demand. Protesting cost, probability of winning the protest, and increase in benefit of winning protest exert great impact on the evolution of resident’s strategy decision on whether to protest. The paper can help to predict and affect the strategy evolution of the two parties, which will promote smooth progress of old community renovation.

Urban-rural integrated communities (URICs) are transitional areas for agricultural transfer population (ATP) in the process of urbanization in China. In the current urban renewal context, the demolition and renovation of communities often result in ATP living in a precarious situation and being marginalized in the city. Sustainable urban renewal should change this situation, take the transformation of URICs as a breakthrough, and promote the urban integration of the ATP. Based on the survey of the National Health Commission of China in 2017, this paper investigates the effects of community participation and community identity on community integration, using the ordered probit model with data of the ATP living in URICs. The results show that both community identity and community participation positively influence community integration, and there are intergenerational differences. The mediating effect test shows that community identity plays a mediating role in the process of community participation, influencing community integration. The findings of the study provide possible ideas for the practical promotion of community integration and urban integration of the ATP, facilitate the implementation of sustainable urban regeneration to reduce the costs of citizenship, and maximize the benefits of the cumulative effects of urbanization for all segments of the population.
