This paper studies the spatial forms and cultural sustainability of the Damazhan and Xiaomazhan historical area, the only area that reflects the development of the assembled-clan hall culture in Guangzhou. In the face of modernization and reconstruction, traditional culture plays an increasingly crucial role in modern cities, determining the expression of architectural uniqueness and continuous development that adapts to social needs. Therefore, preserving cultural characteristics is more relevant than ever. This study combines historical literature research with typo-morphological analysis to establish analytical strategies that link cultural sustainability with spatial evolution from the perspective of sustainable development. The analytical framework consists of three parts: First of all, through historical literature research, a thorough analysis is conducted on the cultural and social influencing factors from the Dynasties of Song, Yuan, Ming, Qing and the Republic of China to the reform and opening up period. Secondly, feature elements of the location are extracted, and a typo-morphological approach is used to analyze the sustained changes in spatial forms. Finally, the relationship between changes in block form and building types and the inheritance and development of traditional culture are demonstrated. The analytical results indicate that the continuity of cultural characteristics is embodied in the continuity of the block and architectural spatial characteristics, while cultural transformation and man-made social factors affect the changes in spatial forms. This paper combines the perspective of cultural sustainability analysis with the traditional typo-morphological approaches of urban spatial analysis, supplementing the existing typo-morphological methodology. In addition, guiding the development of urban morphology from the perspective of cultural sustainability is of prominent practical significance.

Community is the foundation of modern cities, where urban residents spend most of their lifetime. Effective and healthy community design plays a vital role in improving residents’ living quality. Pedestrian network is an indispensable element in the community. Successful pedestrian network design can help the residents be healthy both physically and mentally, build the awareness of “Go Green” for the society, and finally contribute to low-carbon and green cities. This paper proposes a community pedestrian network design method based on Urban Network Analysis with the help of the Rhino software. A case study of a typical community in Guangzhou, China was implemented, specifying the steps of the proposed method. The findings presented include the features of the citizens and the accessibilities of the neighbors that are obtained from the community pedestrian network simulation. The limitation and scalability of this method was discussed. The proposed method can be essential to designing healthy and sustainable communities.

Low carbon sustainability has been addressed in China’s sustainable urbanism strategies as a response the impact of climate change. This study empirically examines the relationship between household factors and carbon emissions in the context of community regeneration through the use of correlational and regression analysis. The participants were drawn from the Dadong community in Guangzhou, China, who has been participating in low-carbon community regeneration. In total, 102 valid questionnaires were obtained from homeowners and the data were analyzed with SPSS and STATA software with an OLS estimate method, checking for BLUE to identify and decide upon the degree of correlation among the variables. The results reveal that family carbon emissions were primarily impacted by house area and income. This study found that larger houses tended to have higher carbon emissions, emphasizing the importance of using low-carbon materials and facilities in community regeneration. Additionally, households with higher incomes tended to have more household appliances, which can contribute to higher carbon emissions and potentially lead to conflicts between different actors involved in low-carbon community regeneration. To reduce household carbon emissions, low-carbon community regeneration develops through interactions and transformations among different actors. However, there has been a lack of research examining the mechanisms underlying the process of low-carbon community regeneration involving the various stakeholders. Using the reference of the actor–network theory (ANT), this research innovatively reveals the mechanisms related to key actors (community government) and multivocal obligatory passage points (OPP) with a synchronous process (problematization, interessement, enrollment, mobilization) through interactions and transformations made by different actors. Finally, the study highlights the need for further research on the low-carbon community or urban regeneration with innovative technological and self-regulation strategies.

This study investigates the spatiotemporal patterns of land development intensity and green economy development at the district and county level in nine cities within the Pearl River Delta (PRD). A comprehensive evaluation framework is developed using a coupling coordination degree model and panel vector autoregression (PVAR) model to explore the spatial and temporal evolution of their relationship. The research reveals several key findings. (1) In 2013–2023, land development intensity followed a pattern of “concentration in the east and south, and sparsity in the west and north”, highlighting significant regional imbalances. (2) In 2013–2023, high-intensity development areas tended to cluster together, forming high-value zones, while low-intensity areas were often located next to similarly underdeveloped regions, reflecting a “low-value connection” trend. (3) There is a long-term stable co-integration relationship between land development intensity and green economy development. This study fills a gap in research at the district and county scale and offers practical insights for optimizing regional growth strategies and fostering green economic development across different areas in 2013–2023. These findings contribute to the design of balanced and sustainable development policies in the PRD, addressing both economic growth and environmental sustainability.

In the decision-making process for investing in heritage buildings (HBs), various factors such as costs, interests, and tenancy terms influence investors decisions. Understanding the motivations of these investors can facilitate the involvement of social forces with diverse interests in adaptive reuse projects. This paper examines the primary barriers to revitalizing heritage buildings through adaptive reuse decision-making. The specific objectives of this study are as follows: i) To explore the barriers faced by investors in the adaptive reuse of heritage buildings. ii) To provide a comprehensive review of the factors influencing the adaptive reuse of heritage buildings, with a particular focus on developing countries. Through structured interviews with 19 investors and field research, three typical categories in the adaptive reuse decision-making process were identified: i) tenancy terms, ii) function, and iii) fire control problems. These findings indicate that vacancy is detrimental to the protection of heritage buildings, while rent plays a significant role in safeguarding them, as revealed by a correlation analysis using quantitative methods. Policymakers should better understand the expectations and needs of the public investors better to enhance support for optimal adaptive reuse decisions.

The rise in aging world populations poses enormous concerns, among which is the critical topic of how to promote active aging by improving the health and well-being of the elderly. Accordingly, installing elevators in old residential buildings has become a main issue in age-friendly community regeneration to make it easier for the elderly to go outside. There is limited evidence on stakeholder involvement in age-friendly community regeneration. Some studies have overlooked the fact that fostering age-friendly communities in developing countries requires innovative governance for inclusive physical and social features despite the low awareness of citizen engagement. With reference to community governance as a structure and process, a theoretical framework is proposed to understand the practice of elevator installation in age-friendly community regeneration in Guangzhou, China. This study adopted the questionnaire survey method and collected 455 valid samples (150 valid samples with installed elevators; 305 valid samples did not install elevators). The findings led to the following conclusions: (1) shared common interests lead to effective community governance and smooth elevator installation; (2) some communities failed to install elevators due to opposition from people whose interests were hindered; and (3) it is important to set up self-governing organizations and find key people in community governance for interest-based negotiation. This paper’s contribution is that it makes up for the deficiency in the previous research that has neglected the elderly’s participation in public affairs via age-friendly community regeneration. Finally, this study suggests further research on the dynamic processes of different types of age-friendly community regeneration affairs.
