Summary: The research suggests that the assessment index system of urban resilience should comprehensively consider the quantity and quality of supply and demand, and establish grade standards. Through case analysis, it is found that urban resilience exhibits a center-periphery sprawling spatial structure with a lack of resilience, and it is mainly driven by quantity. In urban resilience governance, it is important to focus on balancing supply and demand and supporting new technologies.

Summary: This study has established an integrated evaluation framework to analyze the spatial match between green space supply and social demand in urban areas. Using Beijing as a case study, the researchers simulated urban waterlogging risk and considered specific demand criteria related to waterlogging hazards and population needs. The street-level balance of existing and future green space demand was quantified, and key locations for strengthening green space supply in Beijing were identified. This study provides an integrated evaluation of green space accessibility and serves as a foundation for urban land-use planning strategies.

Summary: Global urbanization has led to drastic land use change, interfering the ecosystem services supply-demand balance, threatening human well-being. This study assessed the effects of urban spatial expansion on ecosystem services supply-demand mismatch in the Guanzhong Plain Urban Agglomeration using the Future Land Use Simulation model and expert-based Land-Use and Land-Cover Change matrix. The results revealed that urban expansion resulted in declining ecosystem services and increasing supply-demand mismatch, posing a threat to the sustainability of ecosystems.

Summary: Accelerated urbanization has exacerbated the severity of disaster situations, particularly geological disasters, floods, fires, and others. Urban green spaces, as external disaster prevention spaces, play a crucial role in providing shelter and housing during high-frequency disasters. However, current studies lack sufficient consideration of disaster distribution and population demand, leading to conflicts between green space supply and demand. This study explores the efficiency improvement of disaster-prevention and risk-avoidance green space (DPRAGS) by focusing on matching supply and demand. Using the main urban area of Nanjing as a case study, the research combines ArcGIS and the maximum capacity limitation coverage model to analyze urban infrastructure, disaster risk, and the demand and supply of DPRAGS. The results show that a unitized planning method based on supply and demand matching can better meet refuge requirements and improve the rationality of green space layout. This study enriches the theory of urban green space planning and provides guidance for DPRAGS planning in densely populated metropolises like Nanjing, aiding in the development of emergency plans and management regulations to enhance evacuation efficiency and overall urban disaster prevention and emergency management capabilities.

Summary: The spatial transfer of ecosystem services is crucial for meeting the demands in areas with uneven spatial distribution of natural and social economic development. However, there is a spatial mismatch between the supply of ecosystem services and the demands from cities. The study in the Central Plains urban agglomeration found that natural spatial transfer alone cannot transport ecosystem services to the corresponding population centers, highlighting the need for intercity cooperation in ecosystem management and landscape planning to achieve sustainable development.

Summary: Urban green space (UGS) is essential for human well-being and health, and the inequity in UGS supply has attracted widespread attention. In China, there are significant regional disparities in UGS supply, with less developed cities having more UGS. Increasing the buffer radius gradually improves the equity of UGS supply among cities.

Summary: This article analyzes the dynamic evolution and spillover effects of infrastructure resilience levels in 283 prefecture-level and above cities in China from 2010 to 2019 using kernel density estimation, exploratory spatial data analysis, and spatial econometric models. The research results show that the overall level of urban infrastructure resilience has increased, with the eastern region having a higher level than the national average. High resilience levels are mostly found in cities with more developed economic and social conditions in Eastern China, while areas with lower resilience levels include cities in Central, Western, and Northeast China. There is a significant spatial clustering characteristic of national urban infrastructure resilience, with a distribution from hotspots to coldspots along the coastal to inland regions. There is also a differential spatial spillover effect of national urban infrastructure resilience, which is strengthened by the economy, financial development, population agglomeration, and government funding, and weakened by urbanization, market consumption, and infrastructure investment.

Summary: In this study, the researchers used Tencent location request data to examine the variations in collective human activities in response to rainfall in 346 cities in China. The results showed that a 1 mm increase in rainfall intensity is associated with a 0.49% increase in human activity anomalies. The study also highlighted the unequal urban resilience to rainfall across China, calling for an overhaul of current heavy-rain-alert standards.

Summary: To understand passengers' acceptance of a fare incentive policy, this study examined the effects of the policy on passengers' route choices and found that socio-economic variables, travel characteristics, travel cost, departure time, and travel distance significantly influence passengers' route choices. Additionally, there are differences in route choices among passengers with different travel purposes and times.

Summary: Urban parks are important for enhancing health and wellbeing, but their supply is inadequate and unevenly distributed. Existing studies on spatial equity of park distribution have mainly focused on supply attributes and ignored residents' demand and preferences. This study developed a multi-scale Supply-Demand Equity Index to assess park distribution equity from both supply and demand perspectives, and highlighted the importance of considering residents' perceptions and variations among social groups. The results showed that assessing supply based on accessibility to most often used parks and demand based on perception can reveal hidden patterns of spatial inequity and identify areas of mismatch between supply and demand. This study provides a nuanced approach to equity assessment and has implications for urban park planning and management.

Summary: This study explores the relationship between supply and demand for amenities in expanding urban areas, evaluates the rationality and effectiveness of amenity distribution, and provides suggestions for adjusting the distribution of amenities. The study finds that the supply-demand relationship is mainly balanced, with higher balance in the core of the old urban area and surrounding areas, and lower balance in developing urban areas.

Summary: This paper establishes a supply-demand matching assessment model for smart government services (SGS) from citizens' perspective and conducts a case study in Nanjing. The results show that the overall demand exceeds supply, but there is supply matching demand in the existence dimension and demand exceeding supply in the related and growth dimensions. The study also confirms the heterogeneity of the supply-demand matching degrees caused by citizens' age and usage frequency. Practical implications are proposed, including adjusting SGS supply based on citizen investigation, increasing citizen participation, and balancing heterogeneity and information privacy security of SGS supply. This study enriches the theoretical framework of SGS and provides guidance for global governments in formulating sustainable SGS supply strategies.
