Online platforms have been increasingly in use for reporting neighborhood issues. SeeClickFix is one of these tools implemented, through which citizens can report non-emergency maintenance issues, such as potholes, noise complains or illegal graffiti, to the local governments. In this paper, we analyzed SeeClickFix data to examine whether there were any variances across neighborhoods in their issue-reporting patterns and the likelihood of their problems being acknowledged and resolved by the government. Our findings reveal that higher-income neighborhoods are more likely to report issues and experience higher response rates. Walkability was also associated with more reporting. We additionally conducted street observations to confirm that socioeconomically more stable neighborhoods have a higher tendency to report issues. These findings carry important implications for who takes advantage of the technology designed for civic engagement and, as a result, reaps the benefits for improving their living environments. Future research and practice will need to consider these implications to achieve neighborhood equity in the era of rapid technological advancements and remote service deliveries.

Assessing urban sustainable development performance is vital for advancing global sustainable development goals (SDGs), yet it's often hindered by insufficient statistical data. Here we established machine learning models with the consideration of autocorrelation feature to fill 27 % of the missing values, achieving an average R² of 0.83 in our developed urban SDG framework, which encompasses 117 indicators for 286 Chinese cities. Our findings reveal a notable enhancement in the overall sustainable performance of Chinese cities from 2001 to 2020, with heightened competition particularly evident among middle-ranked cities. However, the distribution of urban SDG Index scores unveils significant spatial heterogeneity; while inter-regional disparities are diminishing, intra-regional differences among cities are widening. Our results after post-upscaling show a strong correlation with previous comprehensive national studies that utilized more indicators. Additionally, they provide extra insights compared to prior urban-scale studies that employed a fewer indicators. These results can assist policymakers in discerning the performance of urban SDGs and formulating appropriate solutions.

Urban mobility is a complex system influenced by various factors such as infrastructure, technology, and human behavior. Agent-based modeling (ABM) has emerged as a valuable tool for simulating and understanding urban mobility dynamics.

This paper provides a comprehensive review of ABM applications in urban human mobility, offering insights into prevailing trends in this field. The analysis of model scales highlights the predominance of area and city scales, highlighting the need for greater exploration at the intersection, metropolis, and street scales. Furthermore, the examination of technological environments shows a reliance on desktop and laptop computers, complemented by a growing adoption of specialized ABM tools such as SUMO, Anylogic, NetLogo, GAMA, and MATSim.

Additionally, the study correlates ABM objectives with societal needs, revealing areas of alignment and gaps. While competitiveness and smart mobility receive considerable attention, there is a pronounced lack of focus on improving urban accessibility, sustainability, and public health. The analysis underscores the importance of addressing these gaps to ensure that ABM applications contribute effectively to addressing societal challenges.

This study examines the dynamic changes in side-street trade areas in Seoul, focusing on their growth trajectories to propose strategies for sustainable development. Using data from 1005 side-street trade areas from 2015 to 2019, the study employs Growth Mixture Modeling (GMM) to categorize trade areas based on growth patterns. The findings reveal that over half of these trade areas have experienced sustained decline. Incorporating initial store density, a probabilistic analysis highlights the significant role of initial conditions in shaping future trends.

Spatial autocorrelation analysis using 2015 initial store density data revealed statistically significant clustering patterns in approximately 10 % of trade areas. Both high-density and low-density areas exhibited a tendency to cluster, with high-density clusters occasionally displaying localized synergistic effects, suggesting potential for continuous growth in specific cases.

Additionally, the study explores industry-specific density changes across restaurant, service, and retail sectors, identifying distinct growth patterns and their interactions with overall trade area trends.

Key recommendations include designating critical commercial hubs as density management zones to regulate overall and industry-specific density levels. Policies such as subsidies or tax benefits for underrepresented sectors are proposed to encourage industry diversification. Furthermore, rent control measures are suggested to mitigate the adverse effects of gentrification, preserving the unique character of trade areas.

This research provides actionable insights for policymakers and entrepreneurs, contributing to the development of more sustainable and adaptive strategies for urban commercial districts.

Foreign investments in knowledge-intensive business services (KIBS) have significantly reshaped the economic and spatial structures of many post-socialist European cities. Despite this, little is known about the intraurban locational behaviour of foreign KIBS and how it differs from their domestic counterparts. This study examines the underlying factors influencing location choices of both foreign and domestic KIBS in Belgrade, a city undergoing complex post-socialist urban economic restructuring. Utilising disaggregated micro-geographic data on KIBS established from 2012 to 2019 and employing a count data model, this analysis reveals key similarities and differences in their employment locational patterns. Both domestic and foreign KIBS are drawn by the economies of localisation, the old CBD, and, to a lesser extent, main streets and commercial areas. However, distinct locational preferences are evident as domestic KIBS are more dispersed, prevalent in densely populated areas and high-status residential neighbourhoods, while foreign KIBS are primarily concentrated in New Belgrade's emerging CBD, characterised by modern commercial infrastructure and better connectivity. These findings contribute to the broader understanding of how globalisation and neoliberal urban policies shape post-socialist cities, highlighting the significant role of foreign KIBS in creating spatially distinct “global city zones” and raising questions about their local embeddedness.

The classical Urban Spatial Change (USC) hypothesis efficiently summarizes urban development patterns through population changes across space but faces disputes regarding its generality and applicability due to its reliance on empirical research primarily from Western contexts. This paper provides the most up-to-date examination of the complete trajectory of Shanghai's remarkable urban transition from a small county to the world's third-largest megacity over 177 years (1843–2020), based on long-term population spatial changes within the USC hypothesis framework. The findings suggest that while Shanghai generally follows the conventional USC trajectory of centralization, decentralization, and recentralization, it also exhibits notable heterogeneities. Those include the bypassing of disurbanization and highly compressed processes following a sequence of urbanization, suburbanization and reurbanization, strong government interventions accompanied by a complex and dynamic interplay between market forces, and a central role of inter-regional migrants throughout Shanghai's urban life cycle. The results support the view that while the USC hypothesis provides a generalized summary of urban systems and offers a concise overview of urban changes, further refinement is necessary to accurately capture the diverse trajectories across different types of cities.

Analysing two opposing parties' votes at the neighbourhood level through political theories, geographical context, and voting preferences is underexplored. This is important in global cities such as Istanbul (Türkiye), which is undergoing economic and democratic development. This paper analyses the clusters and hot spots formed by the vote shares of the right-wing Justice and Development Party (AK Party) and the left-wing Republican People's Party (CHP) using Local Spatial Autocorrelation (LISA) and Optimised Hot Spot Analysis (OHSA). Additionally, the paper examines the relationship between the vote rates of the two rival parties and nine socioeconomic, socio-environmental and demographic variables through local spatial modelling. Using Multiscale Geographically Weighted Regression (MGWR), various findings have been reached that these parties, which have been competing against each other since 2002, confirm the polarisation theory in certain social profiles and spaces. The AK Party vote share correlates negatively with the socioeconomic index, but it shows no relation with the built environment or mean household size. Also, there is a positive relationship between CHP vote share and socioeconomic index and built environment, there is a negative relationship between mean household size. This study provides a multi-scale analytical framework to explore the local differentiation of electoral outcomes and political theories. In future studies, comparison with various variables, cities, and periods are recommended.

In Hong Kong, numerous low-income households reside in subdivided units (SDUs), experiencing poor housing conditions, compromised living standards, and housing precarity, driven by the micro-segregation resulting from housing policies and unaffordable housing prices. To address these challenges, the Hong Kong government has initiated a tenancy control scheme. This study assesses the effectiveness and implications of this tenancy control scheme. Quantitative data were collected from individuals across pre-test and post-test stages. The pre-test was conducted before implementing tenancy control and the post-test ten months thereafter. The pre-test collected 303 valid data entries, whereas the post-test collected 202. The changes over time were analysed through scrutiny. The implementation of tenancy control had varied effects on SDU tenants, as it effectively safeguarded their interests and bolstered their confidence by establishing new lease agreements. Tenancy control emerged as a strategy to address social inequality in the housing sector by influencing housing precarity and expenditure. The findings reveal that the implementation of tenancy control has reduced housing precarity, particularly in terms of the confidence in handling rental issues and the right to renew the lease.

Food policy is understood as a means to improve the wellbeing of local communities and territories, cities first and foremost. This structured literature review is designed to outline the current scenario of research on local governance for food policy and the use of accounting, auditing and accountability practices to promote better decision-making and actions. For this purpose, two large databases as well as a list of generalist accounting journals were explored. After applying criteria of inclusion and exclusion a thematic analysis was performed on a final set of 43 peer-reviewed articles. Despite the growing relevance, literature at urban level is still in its infancy. Almost all studies have a different focus, from innovative food policy to sustainable urban food system. Scholars have primarily focused on cities located in the Global North rather than its counterpart Global South. Reflections on the mechanisms of accounting, accountability and auditing are practically absent. Policymakers at urban level would receive valuable insights from new research focusing on how to integrate in food policy robust calculative practices, accountability mechanisms, as well as auditing initiatives. This in turn may improve urban food governance and enhance the effectiveness and impact of urban food systems.

This in turn may improve urban food governance and enhance the effectiveness and impact of urban food systems.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"158 ","pages":"Article 105656"},"PeriodicalIF":6.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Irrational urban expansion debilitates the sustainability of the natural environment and human settlement environment. However, urban expansion research often prioritizes horizontal expansion over vertical growth. In this study, we proposed a method to measure three-dimensional urban expansion. Firstly, the random forest classifier was applied to extract construction land in the initial year and the final year to detect incremental construction land. Then, the Continuous Change Detection and Classification algorithm assisted in pinpointing the conversion time. The building height data was obtained through the map crawler and assigned to the construction land. Finally, the 3D urban expansion was measured by combining construction time and building height. Shanghai was selected as the study area. The results revealed that the construction land area increased by 1015.39 km² since 2000, with an average annual growth rate of 2.58 %; the building volume increased by 1.5 billion m³, with an average annual growth rate of 1.31 %. Though urban expansion continued to spread from the city center to the periphery, the rate of horizontal and vertical expansion has slowed down, and the tendency of horizontal expansion has enhanced. The method can support informed decision-making in urban land use, energy consumption, and human settlement environment.
