A deep analysis of known patterns must be an important lesson as, first of all, we observe transformation of other regions, which gives rise to a question about the possibility of using positive model solutions in other urban contexts. Moreover, in every action contributing to the development of a region with traditions, we should use every potential, understood as accumulated energy and closed in facilities, individuals and their mutual relations. The article is divided into five parts: (1) a short history of Nord-Pas de Calais; (2) a significant introduction to history and spatial issues; (3) a description of corrective measures undertaken on the basis of, e.g., an urban analysis from the moment of taking a decision on ceasing coal mine extraction until today; (4) a description of"a concept for the region"; (5) conclusions---including a catalogue of actions, prepared by the author, where an important aspect will be the use of elements of spatial values and spatial identity of regions in the process of planning spatial, social and economic transformation. In the article, the results of studies conducted in years 2010-2015, based on statistical data analysis, strategic documents analysis and an on-site visit are presented.展开更多

The high-speed growth of the economy not only led China to a period of industrialization, urbanization, informatization and agricultural modernization, but also exacerbated the situation of the urban–rural dual structure. Based on the review of current studies, we first used the analytic hierarchy process(AHP) method to evaluate the urban–rural development and transformation level by population transformation index, land transformation index, industrial transformation index and social transformation index between 1996 and 2012 around the Bohai Rim Region. Then, based on the results of each index, we used the exploratory spatial data analysis(ESDA) method to investigate the spatial autocorrelation of the change in the urban–rural development transformation index during the 16-year period using Global Moran's I index and Local Moran's I index. Finally, we investigated the mechanism of change of the urban–rural development transformation index at county level, summarizing five main factors:(1) the radiation from the surrounding big cities,(2) the acceleration of the urbanization process,(3) the upgrading of the industrial structure,(4) the publishing and implementation of a macro development strategy and regional policy, and(5) natural factors such as topology.展开更多

On the one hand, the Alliance structure with the United States as the pivot has experienced transformation from a hub-spokes system to a network, has formed the hierarchical layout of new alliance, quasi-alliance and potential alliance, On the other hand, emerging economies represented by China and Russia, while reinforcing the existing coordinate security framework, reshape the Asia-Pacific and even the whole Eurasia geopolitical posture through strategic initiatives such as the Belt and Road Initiative, the Eurasian Economic Union. As the third force in the Asia-Pacific security architecture, the Association of South-East Asian Nations(ASEAN) with the construction of a series of multilateral security mechanisms provides dialogue platform for the two security architectures led by major countries, and has also become one of the feasible paths to realize the future holistic security architecture in the Asia-Pacific region. Meanwhile, the major countries strategic competitions have intensified, which has gradually eroded the ASEAN ‘s cohesion, neutrality and even the central position in a holistic security architecture. The future's reconstruction of the Asia-Pacific security architecture needs to find new strategic consensus and reconfirm the ASEAN central position.展开更多
