疏解非首都功能背景下,北京市的城乡结合部面临调整经济结构与改善人居环境的机遇和挑战。本文以朝阳区为例,结合定量分析与定性讨论,聚焦人居环境与经济系统的协调性问题,剖析协调水平变化的时空间特征及原因。研究发现:2010—2019年期间,朝阳区城乡结合部人居环境与经济系统的协调水平上升明显,空间均衡性有所提升,协调状态呈现出从人居环境滞后过渡到经济系统滞后的演变过程。疏解非首都功能及相关政策是影响协调状态演变的重要因素,它提高了人居环境质量,引发了经济系统的动态调整,短期内使协调水平发生了较大波动,随着人居环境改善幅度逐渐超过经济系统,协调水平出现了下降趋势。提高城乡结合部的可持续发展能力,应重点关注人居环境与经济系统的协调性问题,兼顾地区人居环境改善与经济发展的需求。  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 studies the territorial effects of the LEADER approach in Southern Europe, by analysing the region of Andalusia (Spain). Our research has revealed that, in many cases, projects were concentrated in the most dynamic, most populated areas, with a well-established business network with the financial and organizational capacity required to access European funding. In these areas, the economic leadership of the most dynamic municipalities has been reinforced at the expense of more depressed areas with little social capital and few businesses. These programmes have not, therefore, helped to mitigate territorial imbalances. In a minority of rural areas, however, this trend was not observed, which shows that although territorial inequality is a widespread problem in the practice of neo-endogenous rural development, it does not affect all areas to the same degree.  相似文献

The defining element of island regions is their isolation, the separation of the islands from the mainland; there is an inherent notion of natural border. This condition has preserved ecosystems and protected against outside threats, stimulating ‘coevolution’ between man and the environment, a fundamental ingredient of sustainability. But insularity also means the evident added costs of access to markets which, together with territorial limits and the scarcity of basic resources, especially on small islands, hinders their socioeconomic development. These costs are even greater in the case of outlying islands, which suffer from a ‘double insularity’ in the form of both external and internal borders. For this reason, it is common for governments to establish various forms of support, from tax exemptions to the creation of permanent aid funds, like those implemented by the European Union for the outermost regions. This article discusses these aspects in the case of the Canary Islands, an example of a European outermost island region. The findings show that the support measures have not always been favourable for all the islands.  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

This paper explores the location strategies of multinational enterprises (MNEs) from emerging countries (EMNEs) in search for regional strategic assets. The analysis is based on a systematic comparison between EMNEs and multinationals from advanced countries (AMNEs) in order to unveil similarities and differences between these two major sources of foreign investment into the regions of the European Union. The empirical results suggest that EMNEs follow a distinctive logic in their location strategies. They are attracted by the availability of technological competences only when their subsidiaries pursue more sophisticated and technology-intensive activities. Conversely, EMNEs share some behavioural similarities with AMNEs in their response to the spatial agglomeration of investments.  相似文献

In polycentric urban regions several distinct cities, none of which is dominant, cooperate and compete with each other to attract inhabitants and firms. In such settings city branding strategies do not solely affect one city, but the entire region. We examined how city branding in the face of ecological modernization, that is, delivering higher added economic value, while lowering environmental impacts, is playing out in the Dutch Randstad and the German Rhine-Ruhr. Our findings show that regional identity formation occurs at the sub-polycentric urban region level, coinciding more with (historical) economic profiles than with planning imaginaries. The Dutch cities profile themselves more along the lines of ecological modernization than their German counterparts. Differences between subregions within each polycentric urban region are also noticeable, where more industrialized regions, such as the Ruhr or southern Randstad focus on ‘green’, ‘liveable’ and ‘knowledge-oriented’, while cities with stronger knowledge-intensive sectors portray themselves as ‘smart’ or ‘sustainable’. Cities generally substantiate their profiles through projects, but a significant gap persists between reality and aspirations for improved environmental conditions. This is especially true for the Dutch cities, where many claims, but little visible action can be observed.  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
