The literature shows that market size favours firms’ vertical disintegration because it reduces transaction and knowledge coordination costs. The existing evidence is based primarily on cross-sectional data and on the manufacturing sector, with little or no attention is given to longitudinal data and services. This paper estimates the effect of urban size on the purchase of service inputs by knowledge-intensive business service firms located in the metropolitan region of Milan. Relying on a rich panel dataset, and adopting different econometric techniques to overcome endogeneity, we find a positive and statistically significant effect of increased urban population on the degree of KIBS vertical disintegration only when urban size is measured at the province level. We also find that this effect holds particularly in the case of traditional professional- rather than technology-related activities. 相似文献

Within the debates about the socio-economic advantages of cohesive urban regions, several barriers to institutional integration are said to exist, especially when a metropolitan government is absent and integration relies on inter-municipal cooperation. Some barriers are associated with different urban region structures, such as the asymmetric power relations and sociocultural contrasts between municipalities in systems with dominant core cities, or the lack of a leading city to overcome fragmentation and provide a shared identity in polycentric urban regions (PURs). This paper investigates whether urban regions formed around second-tier cities, whose features depart from both dominant core and PUR models, are able to mitigate these barriers when pursuing integration strategies. The analysis relies on interviews with municipal leaders in three representative European case studies, examining how they perceive the barriers to inter-municipal relations in second-tier urban regions. The findings show that perceptions vary not only between regions, with the three cases following different trajectories of integration, but also within regions, according to the geographical and socio-economic context of municipalities and the legacy of past relations. In general, barriers to integration are not minimized without explicit efforts to rebalance power relations, approach political cultures, mobilize core city leadership and develop a metropolitan identity. 相似文献

Drawing on a detailed analysis of the historical and current development of lighting in Copenhagen’s Tivoli Gardens, this article addresses how this site of extraordinarily diverse illumination exemplifies a carefully orchestrated balance between (1) muted and more vivid forms of lighting, (2) curation of historical styles and promotion of contemporary innovations in illumination and (3) artistic luminaires and those more aligned with popular tastes. Through these themes, we argue that the current strategies towards urban lighting that predominantly promote energy conservation, security, commercial imperatives and place-branding may be supplemented by place-specific design strategies that implement multiplicity, connect past and present, and accommodate diverse desires, dreams and realities. These attributes contribute to the ongoing emergence of what we call a ‘lumitopia’, a space in which an intensified attention to illumination is integral to the particularity of a place or landscape. In the case of Tivoli, this offers a lens to manage nocturnal space so that it becomes more aesthetically complex, inclusive and convivial. 相似文献

The benefits of urban open spaces for improving the quality of life and sustainability in cities are widely recognized. The functions they perform within the framework established by urban planning, as well as their metrics, are now more complex than in the past. It is convenient to develop methodologies for the evaluation of these spaces adapted to the present time to check their level of efficiency, which is useful in urban planning for the establishment of new urban open spaces. The aim of this study is to classify such spaces through a methodology that integrates spatial analysis, configuration analysis, and decision support so as to understand their complexity from a more advanced analytical perspective. In order to do this, a prior exploration of specific literature is carried out, which allows the characterization of the functions of urban open spaces by means of the corresponding analysis variables in a weighted manner. The integrated combination of these advanced tools is a step forward in achieving consistent and detailed results for urban open spaces. They perform their functions best in dense, central, equipped, accessible, connected, and easily walkable urban environments. In addition, future recommendations are provided. 相似文献

Investigation of the reciprocal relation between individuals and space within its cultural and historical evolution allow us to conceive the intrinsic qualities and dynamics of any space in its context and to develop new conceptions to explain what kind of a place it is. Oral history provides opportunities to listen to the voice of space as well as a new way to discover its unique and different characteristics that give the users the feeling of belonging and place attachment. In this study, the place of oral history method in historiography, its use in diverse disciplines related to the shaping of urban space, such as urban planning and architecture, and the possible contribution of oral history to planning and designing urban space are discussed. It is revealed that the use of oral history in research and practice can give effect to develop a sense of belonging for all users and to achieve sustainability of urban memory. For this reason, place-based studies and utilization of oral history method within them are of significant importance, for either acquiring the knowledge embedded in memories or understanding the expectations of users or to provide solutions to place-based problems. 相似文献

Quiet urban areas are places with low noise levels that can help people to support physical and mental wellness. This paper has two objectives: to identify quiet urban areas in Montreal and to check for the presence of environmental inequities in access to such areas for vulnerable groups (children, older people, low‐income individuals, and visible minorities). Using a GIS‐based methodology, 2,282 quiet urban areas were identified in Montreal. The results of a mixed effects logistic regression model analysis showed that there are no major inequities in access to quiet urban areas for the population groups studied. The analysis did, however, revealed substantial spatial disparities in terms of the distribution of quiet urban areas across the boroughs and municipalities examined. 相似文献

Within the making of Portuguese liberal‐representative democracy, the Portuguese Communist Party became a major actor in local government in urban deprived peripheries, shaping Lisbon's Red Belt. In this article, we analyse the communist discourse on the Portuguese urban question, showing how it politicised the urban as a site of unevenness and deprivation, but simultaneously depoliticised it by refusing to acknowledge it as a proper space for conflict. This historical account leads us to a critical debate with proposals that discuss urban politicisation by ontologising “the urban” or “the political”—we argue that these approaches tend to be less helpful in understanding processes of contingent, partial and inter‐related forms of politicisation/depoliticisation of the urban in itself. In contrast, we argue for a more attentive theorisation on politicisation–depoliticisation of the urban condition as a most valuable path to grasp situated formulations of citizenship and, hence, configurations of political regimes. 相似文献

Science Cities: What the Concept of the Creative City Means for Knowledge Production. – The article aims to show that the relationship of science and the city has changed since the 1970s in the context of the knowledgeable society. While cities have principally been regarded as the typical space of science, of new ideas and innovation for centuries, since the 1960s and 1970s universities, research institutes as well as industrial research institutes have relocated to the periphery of cities. There, however, these sites of knowledge have been organized in an ‘urban mode’. That means that the concept of the city as a place of science and innovation has determined the architectural, spatial, and social organization of these sites on the periphery of cities. Certain features of the city have been copied, such as social infrastructures, places of communication, restaurants, cafes etc., while others have been left out – housing, cinema, theatre etc. An ‘urban mode of knowledge production’ in the sense of a very stylized model of the city has become a tool to enhance the production of scientific and technological knowledge. – The article exemplifies this by focusing on a case study, namely of the so‐called ‘Science City’ of the Siemens Company in Munich‐Neuperlach. 相似文献

Contemporary cities in East Central Europe (ECE) represent a hybrid type of urban development which is still generally considered to be a special case and is only exceptionally referred to in the recently intensified debate over the European city. Our paper argues that such exclusion is short‐sighted because ECE cities face structural problems similar to those of their Western pendants. Therefore, the contextual frame of urban research needs to be widened and can no longer be restricted to post‐socialist transition. In this regard, one of the main challenges for future urban development will be the consequences of demographic change. Ageing, new patterns of fertility behaviour and more diversified household structures in line with the Second Demographic Transition (SDT) will have significant implications for urban structures and housing markets, as already known for Western Europe. The purpose of this paper is to work out new questions and hypotheses for future urban research with special respect to Polish and Czech cities. Besides West European experience, recent developments in eastern Germany are taken as a frame of reference, assuming that this specific transition case may, in many respects, be regarded as a forerunner for similar developments in its neighbouring countries. 相似文献
