Gated communities have become the prevalent residential form in Chinese cities, following China's housing reforms. Throughout the COVID-19 pandemic, these gated communities became the basic unit for spatial lockdowns, as they offered an effective means to ensure quarantine control and provide basic necessities to residents behind the gates, as well as allow testing and calculating COVID-19 cases. This research focuses on affordable gated communities in Gucun, Shanghai, populated by comparatively disadvantaged households who were also disproportionately affected by the COVID-19 outbreaks. Drawing on new institutionalism as a theoretical framework, we examine the formal and informal rules adopted among the actors tasked with governing these communities before and during the COVID-19 pandemic. The paper provides critical insights into how the pandemic has affected the different actors' power relations and governance practices, intensifying control and support towards these marginalised urban poor. We conclude, raising whether the state's enhanced presence, through its residents' committees, in neighbourhood governance will endure in Chinese post-pandemic cities.
随着中国住房改革的推进,封闭式社区已成为中国城市的普遍居住形式。在 COVID-19 大流行期间,这些封闭式社区成为了空间封锁的基本单位,因为它们提供了一种有效的手段来确保隔离控制,并为门后的居民提供基本的生活必需品,同时允许对 COVID-19 病例进行检测和计算。本研究的重点是上海顾村的经济适用型封闭社区,这些社区的居民都是相对弱势的家庭,他们也受到了 COVID-19 疫情的严重影响。我们以新制度主义为理论框架,研究了在 COVID-19 大流行之前和期间,负责管理这些社区的参与者所采用的正式和非正式规则。本文就疫情如何影响不同参与者的权力关系和治理实践、加强对这些城市边缘贫困人口的控制和支持提出了重要见解。最后,我们提出了国家通过其居民委员会在邻里治理中的强化存在是否会在大流行后的中国城市中持续下去的问题。

The openness of a park's boundary is crucial in promoting accessibility to the park. However, there are few studies that have quantified the impact of park boundary openness on accessibility at the whole-city scale. Additionally, current assessments of urban park accessibility often overlook the actual spatial distribution of the population that utilizes park services. In this research, based on billions of GPS data records of Tokyo, Japan, we simulated the impact of park boundary openness on accessibility across various scenarios, considering the actual spatial distribution of the park visitor population across the entire city region. We analyzed the impact of park boundary openness on accessibility in different categories of parks and during different visitation times. Furthermore, we examined the marginal effect of improving park boundary openness. Our results show that park accessibility increase as the park boundary openness increase. Larger parks benefit more from an improvement in boundary openness, and visitors who live closer to parks also benefit more. Additionally, the marginal utility of boundary openness improvement decreases as the number of entrances to the park increases. Our research suggests operation strategies for park boundary openness specific to different park usage pattern should be considered and developed.
公园边界的开放性对于促进公园的可达性至关重要。然而,很少有研究对整个城市范围内公园边界的开放性对可达性的影响进行量化。此外,目前对城市公园可达性的评估往往忽略了使用公园服务的人口的实际空间分布。在这项研究中,我们基于日本东京的数十亿条 GPS 数据记录,模拟了公园边界开放度在各种情况下对可达性的影响,同时考虑了公园游客人口在整个城市区域的实际空间分布。我们分析了公园边界开放度对不同类别公园和不同游览时间的可达性的影响。此外,我们还研究了提高公园边界开放度的边际效应。结果表明,随着公园边界开放度的提高,公园的可达性也会提高。规模较大的公园从提高边界开放度中获益更多,而居住地离公园较近的游客也能从中获益更多。此外,改善边界开放度的边际效用会随着公园入口数量的增加而降低。我们的研究表明,应考虑并制定针对不同公园使用模式的公园边界开放度运营策略。

The COVID-19 pandemic notably affected the retail food industry, leading us to ask which types of neighborhoods experienced a rise/decline in “unhealthy/healthy” food outlets following the pandemic. We decomposed neighborhood housing price into 2019 price and the changes since 2019 and examined the repeated cross-sectional associations of neighborhood food availability with housing price measures. Using boundaries of 1640 residential developments in inner Changsha, China, we analyzed food outlet counts within a 0.5-km radius of each development's centroid alongside housing prices and built environment characteristics. We used mixed effects linear regression models to estimate changes in, and differences between, the availability of five types of outlets within established and new developments. Established developments that had higher housing prices in 2019 had more late-night snack shops in 2019 and 2021 and fewer sit-down restaurants in 2021. Increasing housing prices were associated with fewer sit-down restaurants between 2017 and 2019 and more sit-down restaurants between 2019 and 2021 around established developments. Low housing prices might promote availability of “healthy” foods at sit-down restaurants and thereby partly protect residents from high calorie-high fat diets. Community understanding of changes and differences in food availability can provide food resilience against future risks.
COVID-19 大流行对食品零售业产生了显著影响,因此我们想知道在大流行之后,哪些类型的社区经历了 "不健康/健康 "食品店的增加/减少。我们将社区住房价格分解为 2019 年的价格和 2019 年以来的变化,并研究了社区食品供应与住房价格措施的重复横截面关联。利用中国长沙市内1640个住宅小区的边界,我们分析了每个小区中心半径0.5公里范围内的食品店数量以及房价和建筑环境特征。我们使用混合效应线性回归模型来估算老旧楼盘和新建楼盘内五类餐饮店供应量的变化和差异。2019 年房价较高的成熟开发项目在 2019 年和 2021 年拥有更多的夜宵店,而 2021 年则拥有较少的餐馆。房价上涨与 2017 年至 2019 年期间成熟楼盘周围的小餐馆数量减少以及 2019 年至 2021 年期间小餐馆数量增加有关。低房价可能会促进就餐餐馆提供 "健康 "食品,从而在一定程度上保护居民免受高热量、高脂肪饮食的影响。社区了解食品供应的变化和差异,可以提供抵御未来风险的食品。

The impact of land governance and ownership regimes on public green spaces in East African cities: The case of Addis Ababa (Ethiopia) and Kampala (Uganda) 土地治理和所有权制度对东非城市公共绿地的影响:亚的斯亚贝巴(埃塞俄比亚)和坎帕拉(乌干达)的案例

Rapid urbanization is exacerbating the loss of public green spaces in many East African cities; however, little research has investigated how different urban governance practices and land tenure systems may influence green space protection. Scholars have argued that polycentric green space governance approaches and diversified land ownership regimes would lead to better protection of public green spaces. This research examines these theories by comparing two East African cities: Addis Ababa, Ethiopia and Kampala, Uganda. In Addis Ababa, there is a polycentric governance structure, and all public green spaces are state-owned. In Kampala, there is a monocentric governance structure and public green spaces are divided among three land tenure systems (private, communal, and state ownership). We conducted in-depth interviews with 26 stakeholders, from all tiers of government administration including decision-makers, experts, and community representatives. The interviews identified three core factors (inefficient and unenforceable legal framework, limited green space planning and implementation, poor human and financial capacity) and two supporting factors (informal decision-making process and unbalanced power relationships) leading to the gradual loss of public green spaces in both cities. While we did not find evidence to support the superiority of a polycentric governance model relative to a monocentric one, we found evidence that the presence of different land tenure systems may enhance public green space protection. Our research findings provide a more nuanced understanding of how institutional governance, green space planning strategies, and the system of land tenure contribute to the loss of public green spaces in East African cities.
快速城市化加剧了东非许多城市公共绿地的丧失;然而,很少有研究调查不同的城市治理实践和土地所有权制度会如何影响绿地保护。学者们认为,多中心绿地治理方法和多样化的土地所有权制度会更好地保护公共绿地。本研究通过比较两个东非城市来研究这些理论:埃塞俄比亚亚的斯亚贝巴和乌干达坎帕拉。亚的斯亚贝巴采用多中心治理结构,所有公共绿地均为国有。在坎帕拉,实行的是单中心治理结构,公共绿地被划分为三种土地保有制度(私有、共有和国有)。我们对 26 名利益相关者进行了深入访谈,他们来自各级政府管理部门,包括决策者、专家和社区代表。访谈发现了导致这两个城市公共绿地逐渐丧失的三个核心因素(低效且无法执行的法律框架、有限的绿地规划和实施、较差的人力和财力)和两个辅助因素(非正式的决策过程和不平衡的权力关系)。虽然我们没有找到证据支持多中心治理模式优于单中心治理模式,但我们发现有证据表明,不同土地所有权体系的存在可能会加强对公共绿地的保护。我们的研究结果让我们对东非城市的机构治理、绿地规划战略和土地保有制度如何导致公共绿地丧失有了更细致的了解。

Mismatches between energy consumption and population have been identified as key factors in generating energy deficiency. Previous studies have focused on assessing mismatches between energy consumption and population on a global scale owing to insufficient data of sufficient spatiotemporal resolution. In this study, we propose a methodology for quantifying such mismatches using mobile phone signaling data and remote sensing nighttime light data at the global and regional scales in two cities. The mobile phone signaling data were useful for assessing global and regional mismatches between energy consumption and population. The underallocation of energy dominated the central urban areas of the study area. The underallocation of energy was more marked on weekdays. Three forms of mismatch were found in the study areas: U, inverted U, and near-linear-shaped. The job–house balance was negatively associated with regional mismatches between population and energy consumption over time. The job-house balance is negative with energy mismatches. This study measured the mismatch between energy and population at multiple spatial scales and provides scientific support for local energy allocation.
能源消耗与人口之间的不匹配被认为是造成能源短缺的关键因素。由于缺乏足够时空分辨率的数据,以往的研究侧重于评估全球范围内能源消耗与人口之间的不匹配。在本研究中,我们提出了一种方法,利用移动电话信令数据和遥感夜间光线数据,在全球和区域范围内对两个城市的能源消耗和人口之间的不匹配进行量化。手机信号数据有助于评估全球和区域能源消耗与人口之间的不匹配。能源分配不足的情况主要出现在研究区域的中心城区。能源分配不足在工作日更为明显。研究地区发现了三种错配形式:U型、倒 U 型和近线型。随着时间的推移,职住平衡与地区人口和能源消耗之间的不匹配呈负相关。就业-住房平衡与能源错配呈负相关。这项研究在多个空间尺度上测量了能源与人口之间的不匹配,为地方能源分配提供了科学支持。

Identifying the locations of pedestrian crashes in cities contributes to the full implementation of sustainable transportation for all road users. This study examines the pedestrian crash data of Konya, Türkiye, from 2017 to 2022. First, the dangerous and safe road networks in Konya province were identified. Then, spatial and temporal analyses were performed. Kernel density estimation analysis was used to identify five critical locations with high pedestrian crash density. Hotspot analysis was used to identify roads where crashes showed clustering characteristics. Buffer analysis was used to analyse the effectiveness of traffic lights in preventing crashes and three locations where traffic lights were inadequate in preventing crashes were identified. According to the temporal evaluation, pedestrian crashes increased the most at 8 am and 6 pm. Locations where the number of crashes decreased over time were identified by examining the temporal changes in pedestrian crashes using space-time cube analysis. This study highlights the positive effects of improvements in the pedestrian environment on pedestrian safety. New hotspots have emerged in several areas. Therefore, this approach is valuable for early prevention. With the methodology used in the study, the locations of pedestrian crashes and the cause-and-effect relationships of crashes can be evaluated.
确定城市中行人碰撞事故的地点有助于为所有道路使用者全面实施可持续交通。本研究调查了土耳其科尼亚省 2017 年至 2022 年的行人碰撞事故数据。首先,确定了科尼亚省的危险路网和安全路网。然后,进行空间和时间分析。通过核密度估计分析,确定了五个行人碰撞密度较高的关键地点。热点分析用于确定碰撞事故呈现集群特征的道路。缓冲区分析用于分析交通信号灯在预防撞车事故方面的有效性,并确定了三个交通信号灯不足以预防撞车事故的地点。根据时间评估,行人撞车事故在上午 8 点和下午 6 点增加最多。通过使用时空立方体分析法研究行人碰撞事故的时间变化,确定了碰撞事故数量随时间推移而减少的地点。这项研究强调了改善行人环境对行人安全的积极影响。一些地区出现了新的热点。因此,这种方法对于早期预防很有价值。利用本研究中使用的方法,可以评估行人碰撞事故的地点以及碰撞事故的因果关系。

Developing an assessment governance framework for urban digital twins: Insights from smart cities 为城市数字双胞胎制定评估治理框架:智慧城市的启示
IF 6 1区 经济学 Q1 URBAN STUDIES Pub Date : 2024-10-30 DOI: 10.1016/j.cities.2024.105558

The rampant urbanization process has highlighted the need of an efficient governance for urban areas. Nevertheless, cities must face the challenge of adapting to technology advances arising from the digital era we are living in. Under this context, urban digital twins (UDTs) have recently superseded smart cities in the attempt of improving the management of city resources and the live of citizens through the use of sophisticated technology. Although the governance of smart cities has been broadly handled in the literature, the influence of UDTs on urban governance still remains unaddressed. This article aims at closing this gap by developing a framework to assess the contribution of UDTs in the governance of cities. A mixed methodology combining an in-depth literature review, a four-round Delphi technique and the Best-Worst multi-criteria decision making method was implemented to this end. The new instrument consists of a two-tier scheme comprising 7 categories and 33 attributes, of which 26 were deemed as essential for an efficient governance. Institutional dimension prevailed over the remaining sustainability domains. Three performance thresholds were defined: low governance, average governance and high governance. The application of the rating system to the UDT of Singapore as case study determined a high level of governance for this city. Some policies were however recommended to strengthen gaps found in Singapore.
猖獗的城市化进程凸显了对城市地区高效治理的需求。然而,城市必须面对适应我们所处的数字时代所带来的技术进步的挑战。在此背景下,城市数字双胞胎(UDTs)最近取代了智慧城市,试图通过使用尖端技术改善城市资源的管理和市民的生活。虽然智慧城市的治理在文献中已有广泛论述,但 UDT 对城市治理的影响仍未得到解决。本文旨在通过建立一个框架来评估 UDTs 在城市治理中的贡献,从而填补这一空白。为此,我们采用了一种混合方法,将深入的文献综述、四轮德尔菲技术和最佳-最差多标准决策法结合起来。新工具由一个两级方案组成,包括 7 个类别和 33 个属性,其中 26 个被认为是有效治理的必要条件。在其余可持续发展领域中,制度层面占主导地位。确定了三个绩效阈值:低治理、一般治理和高治理。将评级系统应用于新加坡 UDT 案例研究,确定了该城市的高治理水平。不过,建议采取一些政策来加强新加坡的差距。

Recent studies have emphasized cities' need to confront diverse urban challenges. Smart cities offer technological solutions; however, there is a knowledge gap in terms of understanding the effects of technological adoption in cities. Technology adoption in cities must carefully consider technological feasibility, local sentiments, cultural diversity, governance structure, and various socioeconomic aspects. To address this gap, this study investigated smart city development strategies and focused on their integration into urban development plans in Siheung-si in South Korea and NeoCity in Florida. In addition, this study examined the socioeconomic considerations before implementing technology, covering land, infrastructure, people, and governance. Our findings highlight the benefits of effective government-to-government partnerships, emphasizing the importance of knowledge sharing within the smart city ecosystem. This government-to-government partnership serves as a guiding principle for future research and policy interventions.
最近的研究强调,城市需要应对各种城市挑战。智慧城市提供了技术解决方案,但在了解城市采用技术的效果方面还存在知识空白。城市采用技术必须认真考虑技术可行性、当地民情、文化多样性、治理结构和各种社会经济方面。为了填补这一空白,本研究调查了韩国始兴市和佛罗里达州 NeoCity 的智慧城市发展战略,并重点关注了将其纳入城市发展规划的情况。此外,本研究还考察了实施技术前的社会经济考虑因素,包括土地、基础设施、人员和治理。我们的研究结果凸显了有效的政府间合作关系的益处,强调了在智慧城市生态系统中知识共享的重要性。这种政府对政府的合作关系是未来研究和政策干预的指导原则。

Intersecting perspectives: Video surveillance in urban spaces through surveillance society and security state frameworks 交叉视角:从监控社会和安全国家框架看城市空间的视频监控

The current body of literature allows discerning two predominant approaches for comprehending technology-based surveillance in modern societies: surveillance society and security state, developing within the domains of surveillance studies and security studies, respectively. These perspectives offer diverging explanations for the implementation of video surveillance in urban spaces and rarely engage in dialogue. This paper explores whether applying both approaches might be beneficial for understanding the reasons behind the deployment of Closed-Circuit Television (CCTV), as constructed in the legislation and perceived by those involved in tackling urban insecurity. The study focuses on two European cities, Budapest and Milan, selected as the most diverse cases, but sharing the problem of urban insecurity. The surveillance society approach offers a vantage point for the analysis of the legal documents, highlighting the positive construction of the technology as a multi-purpose tool, its symbolic role in security provision, and the central role of authorities in security provision. In contrast, the interview data indicates that both approaches might contribute to understanding social constructs existing around the implementation of CCTV in urban spaces. Although theoretical aspects within each approach are shared across contexts, the nuances of their manifestations in these cities are influenced by variations in historical, socio-economic, and political contexts.
目前的文献中,有两种主要方法可用于理解现代社会中以技术为基础的监控:监控社会和安全国家,分别在监控研究和安全研究领域中发展。这些观点对城市空间中视频监控的实施提供了不同的解释,而且很少进行对话。本文探讨了这两种方法的应用是否有助于理解闭路电视(CCTV)部署背后的原因,如立法所构建的和参与解决城市不安全问题的人员所感知的那样。研究重点是布达佩斯和米兰这两座欧洲城市,它们被选为最不同的案例,但却共同面临城市不安全问题。监控社会的方法为分析法律文件提供了一个有利的角度,突出了该技术作为多用途工具的积极作用、其在提供安全方面的象征性作用以及当局在提供安全方面的核心作用。相比之下,访谈数据表明,这两种方法都有助于理解围绕城市空间中闭路电视的实施而存在的社会建构。虽然每种方法的理论方面在不同背景下都是相同的,但其在这些城市中的细微表现却受到历史、社会经济和政治背景差异的影响。

This paper is focused on the multidimensional assessment of over 1300 cities and regions in Europe based on a powerful and policy-relevant set of 17 smart and sustainable performance indicators. Our approach, based on Shmelev and Shmeleva (2018), is driven by alternative policy priorities expressed in different sets of weights, emphasizing economic, social, smart or environmental aspects of urban performance. Using multiple-criteria decision analysis, the cities and regions were ranked, and well performing cities were selected for a detailed analysis of their policies. Among the best performing cities are Stockholm, Paris and London. The detailed rankings under environmental, economic, social and smart policy priorities are analyzed further. The article examines correlations between indicators including GRP, patents, PM10 pollution, life expectancy and depicts the final smart and sustainable ranking in a GIS format. Our detailed assessment thus allows one to understand the impact of key policies implemented by the leading municipalities, and offers insights on the necessary steps that could be taken by cities and municipalities to improve their smart and sustainable performance. The set of tools developed by Environment Europe Foundation will support the process to generate recommendations for actionable steps and policies for cities around the world.
本文主要基于一套强大的、与政策相关的 17 项智能和可持续绩效指标,对欧洲 1300 多个城市和地区进行多维度评估。我们的方法以什梅廖夫和什梅廖娃(2018 年)为基础,由不同权重集表示的备选政策优先事项驱动,强调城市绩效的经济、社会、智能或环境方面。利用多重标准决策分析,对城市和地区进行了排名,并选择了表现良好的城市对其政策进行详细分析。表现最佳的城市包括斯德哥尔摩、巴黎和伦敦。文章进一步分析了环境、经济、社会和智能政策优先事项的详细排名。文章研究了 GRP、专利、PM10 污染、预期寿命等指标之间的相关性,并以 GIS 格式描述了最终的智能和可持续排名。通过详细的评估,我们可以了解领先城市所实施的关键政策的影响,并就城市和市政当局为提高其智能化和可持续发展绩效而可能采取的必要措施提出见解。欧洲环境基金会开发的这套工具将支持为世界各地的城市提出可行步骤和政策建议的进程。
