With the increasing social and ecological pressures on urban settlements, re-thinking how we produce them becomes a growing concern. Due to the diversity of actors across sectors and backgrounds involved in such design processes, collaboration is of utmost importance. Co-design can thus play a crucial role in integrating aims and knowledge as an evolving institutional process toward feasible, suitable and legitimate projects. While many studies on co-design focus on one-time activities, little attention is paid to conceptualising how such processes occur, involving several actors in dynamic participatory ways. We propose a Co-Design Framework and suggest that collaboration is achieved at many levels within different design steps in the process. Analysing three Chilean public space co-design processes through the lens of our framework, we highlight the intrinsic diversity of such an approach. This study posits that three co-design arenas interact (strategic, transdisciplinary, and socio-cultural) according to their main aims to enable, inform, and legitimise the projects accordingly. Our framework contributes to conceptualising and analyzing co-design and may also be useful to plan and develop such processes in academia and practice.

Urban living labs (ULLs) are progressive forms of interventions that aim to fulfil the sustainability ambitions of cities and communities. They provide opportunities to translate new ideas into practice. The increasing interest among researchers, practitioners, and policy makers in understanding sustainability transitions (ST) has brought new forms of experimentation through which cities and communities can be governed. Recently, there has been increasing attention towards the concept of circular economy (CE). This term promises the creation of distinct city systems in which material flows can be managed efficiently. In this article, we explore how ULLs can become pathways of sustainability transition towards innovative city systems from a circular economy perspective. By adopting a series of systematic analyses, i.e., multiple correspondence analysis and content analysis, we demonstrate the main pathways of circular economy-oriented innovative city systems that have been used in the literature. As a result of this work, we identify the main pathways, namely knowledge production, policy making, co-creation, geographical embeddedness, urban transitions, networks of cooperation among institutions, culture change, and collaborative engagement.

The development of high-speed railway (HSR) new towns in China represents a new phase of suburbanization and has had a significant impact on urban expansion, but not all of its mechanisms and drivers have been studied. This article aims to understand the booming development of HSR new towns in China through the theoretical lens of state entrepreneurialism. It dissects the entrepreneurial behaviors of the local state in a medium-sized city, which harnesses the HSR project strategically to develop a new town. Our findings reveal that local governments play out state entrepreneurialism in developing HSR new towns. They compete with other cities for HSR projects. They are motivated by land revenue generation, career advancement for officials, and maintaining state power. Furthermore, this article contributes to the understanding of interactions among multi-level governments. Local states in China can also exert influence on the policymaking and resource allocation of the national government.

Finding new approaches to overcome complex urban problems such as climate change has always been of interest to policymakers and academics. The changing dynamics of urban development result in the diversification of new practices during which experimentation is used to inform urban practice. Amongst these approaches, urban living labs (ULLs) have become a popular form of urban experimental innovation in many countries in the last decade. These ULLs respond to the increased complexity of future challenges calling for local solutions that acknowledge the local conditions—political, technical, and social. Even though a great deal of attention has been given to this form of urban innovation, there has been little consideration of the learning and innovation processes within ULLs. Based on a comparative case study of three innovation projects in a ULL in the city of Amsterdam, we analyse and discuss the claims of ULLs regarding innovation and the different orders of learning they foster. We argue that in the processes of experimentation within ULLs, combining mechanisms of learning and innovation is key to promoting the development of particular local solutions. However, since the learning processes are especially concerned within a particular ULL learning setting, there is a mismatch between the expectations of policymakers, industry, citizens, and knowledge institutes, as well as how the lessons learned can be useful for other contexts.

In recent decades, various programs have been developed as part of Chile’s housing policies to respond to the housing deficit. Most policies have so far focused on addressing the quantitative, qualitative, and urban deficits, neglecting the social dimension of housing. At the same time, the concept of collaborative housing has been referred to as a possible alternative to respond to these social challenges by fostering social cohesion, collaboration, and mutual aid. This article explores how collaborative housing can tackle the social deficit of housing. Here, we conceptualise this deficit as ‘the lack of non-physical or intangible social characteristics given among residents of a project, such as trust, social cohesion, and a sense of community, necessary for housing to be considered adequate.’ We examined the relation between these two concepts by developing a theoretical and empirical study. The first consisted of a theoretical framework and a review of literature on collaborative housing’s response to the social deficit of housing. Second, we interviewed stakeholders from two study cases. We found that residents in both collaborative housing cases perceive an improvement in their social interactions, sociability, trust, and sense of community in their current homes compared to previous homes. Therefore, we conclude that collaborative housing presents opportunities to tackle the social deficit of housing.

The rapid high-speed railway development in China has faced many institutional challenges for the integrated development of transport and land use in station areas. This paper aims to gain insight into the institutional rules that structure the actors’ interactions and how they influence the integrated development in station areas. The Institutional Analysis and Development framework has been applied to a specific action situation, named Lanzhou West HSR station area in China. The findings from interviews, document analysis, and field visits reveal that Chinese institutional rules obstruct interactions between actors, thereby hampering the integrated development of functions in HSR station areas.
