This paper analyzes the relationship between spatial mobility and social mobility. It develops a two‐skill‐type spatial equilibrium model of two regions with location preferences where each region consists of an urban area that is home to workplaces and residences and an exclusively residential suburban area. The paper demonstrates that relative regional social mobility is negatively correlated with segregation and inequality. In the model, segregation, income inequality, and social mobility are driven by differences between urban and residential areas in commuting cost differences between high‐skilled and low‐skilled workers, and also by the magnitude of taste heterogeneity.  相似文献

ABSTRACT

Geographers interested in how entrepreneurs perceive locational environments have studied their mental maps in several European countries, within the theoretical framework provided by behavioral approach. Such studies have typically employed quantitative techniques, but qualitative studies are relatively new to this line of research. In this article, I examine the mental maps of entrepreneurs in Italy by using a mixture of qualitative and quantitative methods. I present and discuss the qualitative outcomes of this research, focusing in particular on the explanatory location factors and the key influences on the mental maps of entrepreneurs. What emerges is the realization that entrepreneurs are far from being fully rational economic actors, who exploit optimally all information and who are driven only by objective considerations. Rather, their views are also affected by subjective factors, individual’s own insights, commonplaces, stereotypes, and prejudices, particularly with reference to the southern regions of Italy (Mezzogiorno), and of other peripheral areas.  相似文献

This contribution searches for a regional planning conception that allows for a mutual recognition and practical translation between strategies for urban regions and peripheries beyond separate urban and rural categories; taking the Austrian strategic spatial planning context as the example. For this, various notions of polycentricity are discussed and assessed with regard to periphery. The Austrian strategic spatial development concept ÖREK sets out a focused work programme with changing responsibilities and participation of actors. The objectives are targeted and the processes are implementation oriented. Amongst other topics, urban regional issues and peripheral, declining regions are worked on separately. A conceptually integrative, plan-like strategic instrument across the topics and for the whole of Austria is lacking. The ESPON notion of ‘inner peripheries’ is proposed as a complementary concept to the ESDP notion of polycentricity, helping to create a bridge between urban regional and periphery strategies. This has the potential to guide strategic planning practice efforts in Austria towards a yet missing strategic spatial plan for the whole of the country beyond urban and rural categories. Practice relevant conclusions related to the case of Austrian strategic spatial planning are drawn and a need for further, comparative research in a European context is identified.  相似文献

This paper aims at a greater comprehension of the distribution of differentiated knowledge bases and their association with innovation performance. Drawing on evolutionary economic geography, we applied a combinatorial and dynamic view on knowledge bases. The main contribution is the examination of changes and transformations of knowledge bases over time in particular group of regions in Europe and links with innovation performance. Our study revealed systematic regularities between regions with different innovation performance and their knowledge bases. With decreasing regional innovation performance the volatility of knowledge bases over time increases. Innovation leaders evinced stability over time and the most balanced composition of knowledge bases (compared with Central and Eastern Europe regions). Western European countries and regions exhibit the most balanced structure of knowledge bases. An important complementarity and synergy has been identified in the close relatedness of the symbolic knowledge base to the analytical knowledge base. The highest intensity of SME cooperation takes place in regions with a strong analytical base and in regions with the most balanced mix among all three bases (particularly in the UK, the Netherlands and Belgium. Underperforming in innovation show a balanced mix of synthetic and symbolic knowledge bases.  相似文献

Whilst the advantages of the application of Land Readjustment (LR) are well known, there are nevertheless numerous countries in which application of LR is difficult or has not been successful. In its analysis of land readjustment constraints, conditions and the international practice, this paper contributes to improving the implementation of an LR system, particularly with respect to the management process. At the international level, management models in seven countries were studied: Australia, France, Germany, Japan, South Korea, Spain and Sweden. In Portugal, three case studies in the municipalities of Almada, Coimbra and Lisbon were selected, with semi-structured interviews being conducted with the respective managing entities. The management models are distinguished by the type of initiative and leadership processes, relations among stakeholders, managing entities and operating rules. It can be concluded that the role of the public authority as the process facilitator from the very initial stages, the existence of a managing entity and a board of specialists, and the legal conditions governing expropriation are key factors for the improvement of land readjustment management.  相似文献

This themed section brings together five articles focusing on distinct urban sites: Berlin/Munich, Oslo/Bergen, Belfast, Bologna and Barcelona. While there has been extensive research on Polish migrants in cities such as London, this themed issue presents a unique opportunity to explore the experiences of Polish women and men across a range of different cities. In so doing, these articles address key questions concerning implications of the specific structures and opportunities of localities where Polish migrants settle for their gendered everyday life experiences. In providing a short introduction to the themed sections, we begin by introducing some of these questions and consider the ways in which the section can contribute to on-going debates about how migrants experience and navigate place in gendered ways. We argue that gender relations and dynamics are significant to processes of migrant adaptation within particular cities. The ways in which migrants navigate their new locations are shaped not only by institutional structures but also by gendered, classed and racialised power dynamics enacted in and through those spaces. By examining the experiences of Polish migrants across various city spaces in different national contexts, we consider how migrants may adopt particular strategies to negotiate these specific ‘spaces of encounter’.  相似文献

This article examines the wealthier inhabitants of Croydon in the late sixteenth and early seventeenth centuries, focusing on differences in wealth, ownership of property and social relationships. Using wills and subsidy lists, four broad categories of people were identified: gentlemen, yeomen, tradesmen and craftsmen and widows. There was no simple gradation of wealth between these groups; although gentlemen were generally among the richest subsidy payers, yeomen and tradesmen could also figure. In terms of social relationships and the ownership of property, there were differences. Gentlemen tended to marry within their own social group, appoint other gentlemen as overseers in their wills and were more likely to own land outside Croydon. The social relationships of yeomen and tradesmen/craftsmen were more focused on the town itself, as were their land purchases. Two groups of individuals can therefore be seen, not one homogenous entity as some scholars have argued.  相似文献

This article introduces the dossier ‘Spatializing Transnational History: European spaces and territories’. It examines the intersections between transnational history and the so-called ‘spatial turn’ in social sciences, and points at future directions in historical research. It reviews two main different methodological approaches to the problem of space in transnational, comparative and global history and examines recent contributions on the history of territory. Finally, it introduces the contributions to this dossier, which approach the history of modern Europe from a number of transnational and spatial perspectives. The dossier argues that incorporating a combination of spatial approaches, ranging from the examination of transnational spaces, to the interplay between different scales of analysis, and to the historicization of territoriality, into the practice of transnational, comparative and global history may contribute to a deeper, wider and more complex understanding of ‘Europe’.  相似文献
