Much of the rapid urbanization of China’s cities has occurred at the expense of the existing urban fabric. Across the nation, whole city blocks have been replaced with new structures, requiring large numbers of buildings to be demolished while still serviceable. This curtailed lifespan of existing buildings not only comes with an economic cost, but results in loss of urban culture, wastes resources, degrades the environment, exacerbates pollution, and inflames social conflict and instability. For the purpose of evaluating the merits of building demolition, this study develops a decision support system (DSS) for building demolition in the China context from the perspective of sustainable urban renewal. The indicators of this system cover economic, social, environmental, and institutional aspects of sustainable development. Meanwhile, both the individual characteristics of buildings and the external or extrinsic indicators at the neighborhood, local, or city level are taken into account. Based on exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), 24 critical indicators containing qualitative and quantitative factors are identified. These indicators are classified into six parameters: (1) service performance; (2) economic impact; (3) social identity; (4) local development; (5) building location; and (6) building safety. Empirical results reveal considerations of local development to be of greatest significance with the value of standardized factor loading standing at 0.911, followed by service performance (loading = 0.870) and building location (loading = 0.863), with social identity (loading = 0.236) ranking substantially lower. The findings contribute to the practice of urban renewal and, in particular, provide practical guidance to the building demolition decision-making process.

China has enacted numerous green building policies (GBPs) to promote green building (GB) development in the past decades. Investigating the evolution characteristics of China’s GBPs is significant for the future optimization of the GBP system. However, few studies on this topic have been conducted. To bridge this research gap, this paper adopted the methods of bibliometric analysis and text mining to probe the dynamic evolution of the GBPs in China. Firstly, a total 199 collected policies from 1986 to 2019 were grouped into five stages according to the Five-Year Plan. Then, the topics emphasized in different stages and the cooperative relationships among policymaking agencies were discovered by mapping and visualizing the co-word network and co-author network. Based on the derived results, an in-depth discussion was further conducted from five aspects: targets, objects, instruments, GB performance indicators, and the collaboration structure of policymaking agencies. It was revealed that the topics of GBPs evolved from macro to specific, and the types of policy targets, objects, instruments, and GB performance indicators evolved from few to multiple. Additionally, the collaboration structure of policymaking agencies went from dispersive to centralized. This study sheds lights on the dynamic evolution of China’s GBPs and provides valuable references for other countries in need.

Gated communities are the most popular residential pattern in the urban areas of China. However, along with the increasing population density in urban areas, this pattern may have negative influences on people’s daily lives, such as traffic jams. To avoid the negative influences, the government has encouraged residents to open their gated communities; however, few positive actions have been taken. With this background, this study aims to explore the key factors in residents’ willingness to open their gated communities. To start with, a total of 26 potential factors were identified based on a comprehensive literature review. Then, a questionnaire was designed and distributed to collect empirical data. Furthermore, logistic regression was employed to analyze the collected data. Based on the derived results, it was revealed that concerns are different between male and female residents. Male residents regarded “community safety” and “property management” as having a significant impact on their decision to open a gated community, while female residents paid more attention to the factor of “proprietary equity”. The results of this study could provide valuable references that enable the government to better understand residents’ underlying concerns and to make relevant policy decisions.

Urbanization in China has resulted in serious conflicts. Landless peasants are resettled between urban and rural areas in transitional communities. where their rural lifestyles often lead to spatial conflicts. We proposed a conceptual model to provide theoretical guidance for the governance of spatial conflicts and the sustainable transformation of resettled communities. Using field observations and semi-structured interviews, we examined 10 resettled communities in Hangzhou, China. The use of grounded theory to code the interview texts yielded 71 initial concepts and 22 categories that we then refined into six main categories: community physical environment (e.g., quality of private housing), community communication environment (e.g., heterogeneity of community population), landless peasants’ risk perceptions (e.g., impacts on social psychology), community governance capacity (e.g., trust in community’s self-governing organizations), residents’ space perceptions (e.g., awareness of space rights), and space competition behavior (e.g., fighting for public space). Finally, we applied social combustion theory to construct a logical relationship between the core category and main categories. The results show that changes in the physical and communication environments are the root elements (“combustion substances”) of spatial conflicts; the driving factors are landless peasants’ risk perceptions and community governance capabilities; direct elements (“ignition temperature”) are residents’ space perceptions and space competition behavior. Strategies for sustained transformation in resettled communities should prioritize gradual transitions of community space, improve support mechanisms for landless peasants, optimize community governance mechanisms, and cultivate awareness of community rules. This study aids the understanding of the inner mechanism for the sustainable development of resettled communities and has implications for other countries and regions in similar contexts.

The resettled community is a special type of transitional community in China where the residents are urbanized peasants who lost their lands during urbanization development. However, resettled community conflicts (RCCs) are barriers to sustainable community transformation. Focusing on functional conflict, this study identified the conflicts in the resettled community and proposed feasible governance logic for RCCs. The research in this article has a significant theoretical foundation in functional conflict theory. By examining a large sample of cases, seven RCC types were identified (e.g., inner discontent of residents, mass incidents), of which three have positive functions and four have negative impacts. Furthermore, three RCC causes were identified: right-based, interest-based, and value-based conflicts. Their mechanisms for the conflict function are, respectively, the contextual dual-functional, destructive one-way, and structural dual-functional paths. Considering these findings, we propose a dual governance logic of RCC: accommodation and avoidance. Within the dual logic, specific governance strategies are proposed for the different RCC causes and their functional formation paths. This research serves as an important reference for proper policy measures to govern RCCs and promote the sustainable transformation of resettled communities. The methodology adopted can be extended to the study of RCC in broader global contexts.
