Taking the case of China's Yangtze River Delta(YRD) region, we particularly focus on knowledge circulation within and beyond the YRD region by analyzing the pattern and process of knowledge collaboration at different geographical scales during the 2004–2014 period. Results show that the structure of scientific knowledge collaboration as reflected by co-publications has been strongest at the national scale whereas that of technological knowledge collaboration as measured by co-patents has been strongest at the global scale. Despite this difference, the structure of both scientific and technological knowledge collaboration has been functionally polycentric at the megalopolitan scale but become less so at the national and global scales. The ‘globally connected but locally disconnected' pattern of Shanghai's external knowledge collaboration suggests that the gateway role of the YRD megalopolis in promoting knowledge collaboration at different geographical scales will take time before it is fully realized.展开更多

The aim of this paper is to demonstrate that we can support an innovative perspective based on intermediate geographical scales, more useful for outlining the specific features of territory. While we analyze the territory, we should overcome the strictly local scale of the administrative boundaries and create new relationship between contemporary urban concepts （metropolization of territory and metapolis） and the regional ecological patterns. In the case of Valladolid （E） urban/metropolitan area, we focus on both causes and process of city growth. We have understood that it could be inefficient for planning forgetting the real spatial configuration （the city is located in an intersection between two territorial corridors） and misunderstanding the territorial role of the city at different scales （the double centrality in the emerging urban area and in the region）. The significance of this case is to reveal the inter-scalar condition of places as generators of constraints in the contemporary urban fabric and, at the same time, to show the quality and the potential of places in the future urban realm.展开更多
