Offshoring,outsourcing and the economic geography of Europe

Globalization has altered the appeal of each region to host economic activities. As firms are pushed to be more competitive, they develop outsourcing and relocation strategies, displacing some production activities to new emplacements. These changes have important impacts in some regions and are modifying the economic geography of Europe. This paper aims to present the impact that outsourcing and relocation strategies have across European regions and industries as well as to determine some of the characteristics of the more affected regions most affected.     

Spatial characteristics and influencing factors of Chinese traditional villages in eight provinces the Yellow River flows through

Along with global urbanization and the dominant trend toward urban-based policies, traditional villages are facing imbalanced development and the fate of revitalization or decline. In this study, 1,222 Chinese traditional villages in eight provinces the Yellow River flows through have been selected as the typical physical bearers of Chinese civilization of an investigation into the multi-scale spatial characteristics, and multiple influencing factors and mechanisms for regional patterns and spatial differentiation. Spatial analysis methods, including nearest neighbor index and kernel density, are applied to figure out the great regional differentiation in the overall pattern and specific distribution characteristics in each province. Physical environment factors and socioeconomic influencing factors are analyzed and compared using geographical detectors. The results show that: (a) The overall spatial distribution of the traditional villages shows great regional differentiation and is characterized by “two cores,” “three distribution modes,” and “four types of the absence” of traditional villages; (b) the spatial distribution of traditional villages in the Yellow River Basin is affected both by natural factors and by socioeconomic factors, with natural factors having the greater impact; and (c) there is no inevitable correlation between the level of economic development and the rise and fall of traditional villages. By analyzing and revealing the external forces and internal motivation and influencing factors of renewal and evolution, and the wisdom and culture behind the physical places, this research can deepen the understanding of traditional villages, enable traditional society to better adapt to contemporary society, and provide reference for rural revitalization and regional development of rural areas and the Yellow River Basin.     

A structural multisectoral model with new economic geography linkages for Tuscany

This paper describes the Remi‐Irpet macroeconometric multisectoral model. The Remi‐Irpet, based on an input‐output core structure, has its most distinctive feature in the modelling of vertical pecuniary externalities à la Fujita‐Krugman‐Venables which represents the core dynamization mechanism. Our contribution first presents the theoretical background of the model. Second, we present a simulation exercise performed through the model in which we evaluate the structural impact of incoming FDIs for Tuscany. The impact analysis is defined in terms of (i) change in the overall productive capacity and (ii) medium‐term changes in prices and productivity, driven by the changes in the accessibility to labour and intermediate inputs.

基于文化地理学的少数民族传统村落及民居研究

加强少数民族传统村落及民居研究对于维护民族多元文化生态,促进乡村文化振兴具有重要意义。针对少数民族村落及民居研究和保护的紧迫性,讨论了文化地理学对于少数民族村落及民居研究的适用性,从文化生态与景观、文化扩散与整合、文化源流与区划、地方文化与制度、综合演变机制等方面阐释了文化地理学对少数民族村落及民居研究的方法与优势,探讨了文化地理学对于揭示少数民族传统村落特色文化内涵与特质的路径,为深化学科研究和保护少数民族村落及民居提供了较好的研究范式与应用基础。并以瑶族为例,初步提出了少数民族村落及民居研究的框架,旨在进一步推动少数民族村落及民居研究的广度与深度。     

Millennials in the Housing Market: The Transition to Ownership in Challenging Contexts

In the context of rising housing costs, volatile housing markets and changing family structures, I examine the transition to ownership of young adults, and specifically the ownership paths of the Millennial generation. I examine the cohort ownership trajectories within the United States, between 2000 and 2015, and by region and race/ethnicity. The cohort transitions capture the strongly regional and ethnic outcomes of entry to ownership, and the effects of the financial crisis. All groups have much lower rates of ownership entry than earlier cohorts. There is likely to be an adjustment of the path to ownership in the long run and the current outcomes provide evidence that those trajectories will vary by region and race. It does appear that the changing trajectory of access will contribute further to the already growing inequality in cities.
