Urban mobilities in Mumbai: Towards worker-centric platformisation beyond ‘urban solutionism’
孟买的城市交通：迈向超越“城市解决方案主义”的、以劳动者为中心的平台化
Tobias Kuttler（WZB柏林社会科学中心）As digital mobility platforms, such as ride-hailing apps, have become more widespread and popular, they have garnered public and scholarly interest as potential solutions to challenges of climate change, insufficient mobility services, urban congestion and pollution. This paper examines the potential of ride-hailing platforms through a more critical lens. Thereby I draw attention to how platform transportation workers in Mumbai, India, produce mobility services by collaboratively linking the social and material resources of the city. Networks and communities of transport workers have long been essential for providing intermediate mobility services in Mumbai, and continue to do so in the platform era. Building on these observations, I inquire whether there is potential for the creation of worker-centric platform models that benefit both the workers and the larger urban majority. Therefore, drawing on my fieldwork in Mumbai, I first explore how the current model of digital mobility platforms in Mumbai reinforces socio-spatial fragmentation in Mumbai while leaving workers with decreasing earnings and rising work pressure. Considering the agency of platform workers, I then aim to uncover how platform workers appropriate platform mechanisms and engage their collective knowledge and experiences in order to improve their working situation. I draw upon these insights to highlight how worker-centric approaches to digital mobility platforms can contribute to more inclusive and sustainable cities.
随着叫车应用等数字移动平台变得越来越普及和流行，它们作为解决气候变化、出行服务不足、城市拥堵和污染等挑战的潜在解决方案，引起了公众和学术界的关注。本文通过更具批判性的视角考察叫车平台的潜力。具体而言，本文关注了印度孟买的平台交通劳动者如何通过协作链接城市的社会和物质资源来提供出行服务。长期以来，运输工人网络和社区对于孟买的中间出行服务的提供都至关重要，在平台时代仍然如此。基于这些观察，本文探究是否有可能创建以劳动者为中心的平台模式，使劳动者和广大城市居民都受益。根据在孟买进行的实地考察，本文首先探讨了孟买当前的数字出行平台模式如何强化孟买的社会空间碎片化，同时导致劳动者的收入减少、工作压力增加。考虑到平台劳动者的能动性，本文继续揭示了平台劳动者如何利用平台机制、并运用他们的集体知识和经验，来改善他们的工作状况。本文利用这些见解来强调以劳动者为中心的数字出行平台方法如何有助于建设更具包容性和可持续性的城市。

补充租赁住房供应？澳大利亚悉尼低成本和非正规住房的数字市场
Pranita Shrestha（澳大利亚悉尼大学）This article examines real estate platforms and the data they generate to provide new insights into housing markets and practices, focusing on lower-cost and informal sectors, where building or rental regulations are often bypassed or contravened. We examine online listings advertised in Sydney, one of the most expensive cities in Australia and the world, compiling data from four dominant platforms – Realestate.com.au, Flatmates.com.au, Gumtree.com.au and Airbnb.com – each of which offers a particular type of rental accommodation. Using these datasets, we identify a typology of lower-cost and informal tenures and dwelling units, ranging from secondary dwellings and illegally subdivided apartments to shared accommodation and precarious rental agreements. Our study highlights a supplementary supply of rental housing, operating within the conventional private rental market, accessed and made visible via the platforms we examine. Applying a statistical regression approach, we examine relationships between concentrations of informal housing supply and socio-economic variables. The findings reveal intersections between digital platforms and evolving informal market practices and have implications for urban planning and housing policy.本文考察了一些房地产平台及其生成的数据，以便为住房市场和实践提供新的见解；我们重点关注低成本和非正规细分市场（在其中，建筑和租赁法规经常被规避或违反）。我们研究了悉尼（澳大利亚乃至世界上最昂贵的城市之一）的在线房源，并收集了四大主要平台（Realestate.com.au、Flatmates.com.au、Gumtree.com.au 和 Airbnb.com）的数据，其中每个平台都提供特定类型的租赁住宿。利用这些数据集，我们识别了一系列低成本、非正规的租赁住房和住宅单元类型，包括附属住宅、非法分割的公寓、共享住宿和不稳定的租赁协议。我们的研究强调在传统私人租赁市场中存在补充供应的租赁住房，这些住房可以经由我们研究的平台访问和获得。采用统计回归方法，我们考察了非正规住房供应集中度与社会经济变量之间的关系。本文的研究结果揭示了数字平台与不断发展的非正规市场实践之间的交集，可以对城市规划和住房政策产生影响。

跨城市等级的人口流动：中国的城市化是否已从首位城市阶段转向次级城市阶段？
Sylvia JT Jansen（荷兰代尔夫特理工大学）Harry van der Heijden（荷兰代尔夫特理工大学）Peter J Boelhouwer（荷兰代尔夫特理工大学）The population density in megacities in China gives rise to challenges, such as traffic congestion and soaring housing prices. A trend of leaving primate cities can be observed as well as a population increase in secondary cities. These trends might point to an urbanisation transition from the primate city stage to the secondary city stage. Research is needed to determine at which stage of urbanisation China currently resides, and who are migrating across the different levels of cities in this stage. In order to answer these questions, the current study combines the theory of differential urbanisation and migrant selectivity, and analyses city-level migration patterns and demographic characteristics of migrants across the urban hierarchy. The findings indicate that China is currently in the intermediate primate city stage, where the upward migration across the urban hierarchy is driven by younger adults with higher education and income, and a lower likelihood of marriage or parenthood. Building upon global evidence, this research further extends the theory of differential urbanisation by incorporating migrant selectivity into the interpretation of urbanisation stages. It reveals that educated migrants tend to concentrate and move up the urban hierarchy in the primate city stage but might deconcentrate during the secondary and small city stages. This study offers practical insights for policymakers at the national and city levels to develop population growth plans, adjust targeted migration policies and respond to future urbanisation processes.中国特大城市的人口密度带来交通拥堵、房价飙升等挑战。首位城市逐渐出现人口外流的现象，而次级城市出现人口增加的趋势。这些趋势表明城市化可能正在从首位城市阶段向次级城市阶段转变。因此，亟需相关研究来确定中国目前处于城市化的哪个阶段，以及在这一阶段是哪些人口在跨越不同等级的城市进行迁移。为了解答这些问题，本文将差异城市化理论和迁移选择性理论结合起来，分析了城市层面的人口流动变化，以及跨城市等级流动的人口的特征。研究结果表明，中国正处于中级首位城市阶段，跨城市等级向上流动的人群主要是受教育程度较高、收入较高、结婚或生育可能性较低的年轻人。本文以国际研究证据为基础，将人口迁移的选择性纳入城市化阶段的解读中，进一步扩展了差异城市化理论。研究显示，在首位城市阶段，较高水平受教育程度的流动人口倾向于向高等级城市流动和集中；但在次级城市或小城市阶段，则可能倾向于分散。本文为国家和城市层面的政策制定者制定人口增长计划、针对性调整流动人口政策和应对未来的城市化进程提供见解参考。

Abstract
What happens to firms’ innovation activities when new firms enter or leave their urban neighbourhood? We empirically explore the role of knowledge spillovers through firm dynamics using firm-level panel data from Berlin. The results indicate that an increase in firm activities in the neighbourhood through entries and influx positively relates to incumbents’ innovation activities. This finding is restricted to diversity externalities which work on a very small microgeographic scale, vanishing already after a quarter of a kilometre. For specialisation externalities through firm dynamics, we cannot find a link to innovation in incumbents.
当新企业进入或离开其所在的城市街区时，企业的创新活动会发生什么变化？我们利用柏林的企业级面板数据，通过企业动态，对知识外溢所发挥的作用进行实证研究。结果表明，企业的进入和涌入所导致的街区企业活动的增加与现有企业的创新活动呈正相关。这一发现仅限于在非常小的微地理尺度上起作用的多元化外部性，在四分之一公里之后就会消失。对于通过企业动态体现的专业化外部性，我们无法找到其与现有企业创新之间的联系。

在抵抗和意料之外的合作中寻找方向：旅游城市中左翼草根社会组织的角色
Priscilla Santos（葡萄牙里斯本大学学院）Daniel Malet Calvo（葡萄牙里斯本大学学院）This article explores the ambivalent role of a grassroots cultural and activist association and its forced displacement between two districts as a result of the rapidly advancing frontier of gentrification in the city of Lisbon (Portugal). Strong institutional and private pressures led to the eviction of the association from its former location in the now gentrified Bairro Alto and its relocation to Intendente, a formerly degraded and excluded area currently undergoing a transition to marginal gentrification. By combining documentary research of secondary sources and exploratory ethnography that includes interviews with key informants, this article examines how the association has navigated between resistance against urban neoliberalism and its own (unwanted) contribution to the dynamics of marginal gentrification. It concludes by highlighting the need to deepen analysis of the ambivalent nature of activist associations campaigning for the right to the city, while providing clues for understanding how grassroots organisations resist, survive and/or collaborate with the manifold processes of urban change.摘要
本文探讨了一个草根文化和活动者协会的矛盾角色，以及由于葡萄牙里斯本市绅士化进程的快速推进，该协会被迫在两个地区之间进行的迁移。强大的制度压力和私人压力导致该协会从现已绅士化的上城旧址迁出，并搬迁至 Intendente，后者是一个曾经衰落的、被排斥的地区，目前正在向边缘绅士化过渡。本文结合对二手资料进行的文献研究以及探索性民族志研究（包括关键人物访谈等），探讨了该协会如何在抵制城市新自由主义与其自身对边缘绅士化动态的（意外）贡献之间找到平衡。最后，本文强调有必要深入分析众多争取城市权的活动者协会的矛盾性质，同时提供线索以了解草根组织如何抵抗、适应和/或配合城市变革的多种进程。
