Transport infrastructure investment is a cornerstone of growth‐promoting strategies. However, the link between infrastructure investment and economic performance remains unclear. This may be a consequence of overlooking the role of government institutions. This paper assesses the connection between regional quality of government and the returns of different types of road infrastructure in the regions of the European Union. The results unveil the influence of regional quality of government on the economic returns of transport infrastructure. In weak institutional contexts, investment in motorways—the preferred option by governments—yields significantly lower returns than the more humble secondary road. Government institutions also affect the returns of transport maintenance investment.  相似文献

本文从区域地理的视角,通过对俄罗斯转型以来的经济地带、基本经济区、联邦区和联邦主体四个不同层面的区域经济发展空间差异的现状进行动态分析,得出俄区域经济发展差异具有三个鲜明的特征:一是无论在其经济整体下降或增长的同时均伴随着区域之间经济发展差异的绝对或相对扩大过程;二是区域之间经济发展空间差异反映了市场经济在不同区域的作用,即在市场条件基础较好和资源性外向型经济发展有利的区域经济增长优于其他区域;三是形成了大量的"低水平塌陷"区域,即经济指标低于全俄平均数的问题区域数量多,覆盖面大。在此基础上,从自然因素、市场发育水平、体制因素以及社会历史因素等方面探讨了各因素在区域经济发展中的不同作用。  相似文献

Between 1950 and 1990, housing was the driving force behind the spatial growth of the Randstad. Growth poles (1970s) and later VINEX locations (1990–2010) were the main components of growth management. Transport infrastructure has developed greatly since the 1920s. Since 1990, infrastructure development has increasingly become the structuring force for the spatial dynamics of the Randstad. Schiphol was seen as the mainport for airlines, and Rotterdam-Europoort as the mainport for shipping lines and container transport. The landside infrastructural connections for Schiphol and Europoort had a big impact on the growth in the capacity of continental roads and rail lines. ICT- and energy infrastructure are now developing quickly. Recently, Amsterdam Internet Exchange became the largest ICT node in Europe. Finally, the Delta programme was introduced, strengthening the coastal areas and leaving more room for the rivers. For the future, a combination of housing, infrastructure and water for spatial developments will determine the spatial structure of the Randstad further. A compartmentalized plan of the Randstad between the main dikes is presented, which will increase the resilience of functions of the Randstad in the future when the North Sea level is expected to rise substantially. The analysis presented could be relevant for many urban deltas worldwide.  相似文献

This paper focuses on green infrastructure planning in three different regions, namely, the Ruhr in Germany, the Capital Region of Denmark and Greater Manchester in the UK. We investigate planning cultural research heuristics and propose a conceptual refinement of existing planning cultural research and approaches. We use framing and storytelling to show how societal beliefs and cultural assumptions are consolidated as spatial frameworks that guide planning practice. Theories of spatial governance describe how spatial frames are mediated, accepted and changed through institutionalized structures. We present arguments from urban design and implementation research to illustrate how planning ideas materialize. The empirical material presented in this paper shows how cultures of green infrastructure planning operate in diverse spatial contexts and that a dynamic perspective is useful for understanding how planning cultures develop and change over time.  相似文献

This paper tests for spatial spillover effects of state-level telecommunications infrastructure investment on state output, using panel data for 48 U.S. states from 1970 through 1997. As information and communication technologies support more industrial locational freedom, states may use telecommunications infrastructure investment as a competitive tool for attracting factors of production. In a production-function framework, this effect would manifest itself as a negative output spillover effect from telecommunications infrastructure investment. Findings indicate that a state benefits from its own telecommunications infrastructure, but telecommunications investment by other states has a negative impact on its output growth path, and proximity amplifies this negative spillover effect.  相似文献

It is by now well known that return migration of the highly skilled can have a significant impact on knowledge-based development in the regions to which they return. Whereas previous research has mainly focused on developing and newly industrializing countries, this paper looks at high-skilled return migration in an East European transformation economy, namely Poland. In our paper, we propose an analytical framework which integrates migration theory and regional development perspectives. Based on narrative interviews with high-skilled return migrants in Warsaw and Poznań, we show that high-skilled return migrants have an impact on economic development by acting as both investors and innovators, i.e. that they transfer and successfully integrate financial means as well as different types of knowledge into these local economies. Furthermore, the Polish example illustrates that social relations and institutional context are crucial in understanding how high-skilled return migrants contribute to knowledge-based development.  相似文献

DECOMPOSING REGIONAL EFFICIENCY*   总被引:1,自引:0,他引:1  
ABSTRACT Applying an outlier robust extension of the data envelopment analysis (DEA) followed by a geoadditive regression analysis, this study identifies and decomposes the efficiency of 439 German regions in using infrastructure and human capital. The findings show that the regions’ efficiency is driven by a spatial and a nonspatial, arguably structural factor. As a consequence, concrete regional funding schemes, shaped by best practice results, might not be appropriate for all regions. Instead, a more differentiated funding scheme that accounts for both spatial and structural factors seems more promising.  相似文献

This introductory contribution presents some results of the EURBANET project, dealing with European urban networks in the framework of the INTERREG IIC programme of the North‐western Metropolitan Area (NWMA). This project was conducted between 2000 and 2001 by researchers of Delft University of Technology, the University of Glasgow, the University of Dortmund, the Catholic University of Leuven and the University of Nijmegen. The central objective of the EURBANET project was to explore the role of polynucleated urban regions in the reinforcement of the competitive strength and quality of life in the NWMA, as a contribution to transnational spatial planning in the NWMA. Four polynuclear urban regions are involved: Randstad Holland, the Flemish Diamond, the RheinRuhr Area and Central Scotland (Glasgow‐Edinburgh region). One of the conclusions is that it is necessary to move between scales: from the European Union to national spatial policies (and vice versa), between national policies and regional spatial policies and between regional and urban spatial policies. At each scale, specific demands for spatial planning policies in polynuclear urban regions are becoming increasingly relevant. This is a challenge for spatial policies and policy domains like infrastructure policy, transport policy, housing policy, economic and environmental policy. We present an analysis of how polycentricity has become central to recent discussions on European and north‐west European spatial and economic planning. We launch a spatial network approach to integrate spatial policies. These wide perspectives contrast heavily with the current less satisfactory practice of spatial planning on the level of urban networks and transnational governance.  相似文献

This paper attempts to describe the potential of urban transport infrastructure projects such as metro, regional rail and tram, to indirectly work as a catalyst for the development and redevelopment of urban areas as well as the regeneration of declining areas. The paper presents the outcome of research on a sample of 12 European cities—Athens, Bratislava, Brussels, Helsinki, Lyon, Madrid, Manchester, Newcastle upon Tyne, Stuttgart, Valencia, Vienna and Zurich. This research is part of the Transecon project which was funded by the European Commission under the competitive and sustainable growth programme of the fifth framework— and concerned with all kinds of different indirect effects (economic, social and spatial) of new transport infrastructure investments in European cities. The outcome of the research points out that urban transport infrastructure may have a catalytic effect on the development, redevelopment and regeneration of urban areas but there are a lot of other influencing factors which make such re-urbanization processes a successful or unsuccessful story.  相似文献

The goal of this article is to identify the impact of innovations on growth and stagnation regions in Poland. The research procedure consists of two stages. At stage one, Polish administrative units (voivodeships) were arranged on a scale of economically robust and weak regions following data clustering, indicators organized in line with the following aspects of social and economic growth: (1) population and settlement, (2) the economy structure and the labour market, (3) the technical infrastructure and spatial accessibility and (4) the financial situation and level of affluence. Stage two includes identification of the relation between the regional diversification and the distribution of growth and stagnation regions in Poland which is based on canonical correlation.  相似文献

The article focuses on spatializing struggles in relation to Niger's new oil infrastructure and shows how it turned public and political. Two different but interconnected perspectives are employed: first, a historical perspective illuminates how economic theories of growth, visions of industrialization, desires for energy autonomy, political projects for constitutional change and infrastructural developments in neighbouring countries were, from the very beginning, entangled in Niger's oil assemblage. These entanglements made the petro-infrastructure political even before it had materialized. Second, by focusing ethnographically on the spatial dispersion of the petro-infrastructure over different administrative regions in Niger, the article examines territorializing processes in which temporally and spatially separated histories of marginalization were stitched together to reconfigure collective identities. These dynamics go beyond existing explanations of resource curse theories, showing how oil acts as a catalyst that accelerates pre-existing dynamics, slowly transforming the socio-political configuration in which it operates in the process.  相似文献

ABSTRACT.  We evaluate the impacts of enhanced transportation systems on property values for U.S. manufacturing firms, allowing for higher-order spatial error correlation. We use a state-level model of production cost and input demand that recognizes the productive contribution of public transportation infrastructure stocks. Our findings include significant impacts on property shadow values and input composition from both public highway and airport investment. We also find that these effects have a spatial dimension that depends on the proximity of the transport system; at least one and as many as three spatial error lags are significant in our estimating equations. Further, recognizing production growth from transportation system improvements augments the associated incentives for private capital investment.  相似文献

This paper investigates the substratum and infrastructure networks as relevant components of spatial planning. Since 2001, in Dutch government documents on spatial planning the Layers Approach has been presented, with three layers: substratum; networks; occupation patterns. The Layers Approach assumes that the characteristics of the substratum provide conditions for infrastructure networks and that these infrastructure networks then condition the occupation patterns, including the locations for housing, business activities and related services. These more or less hierarchical relationships are supposed to produce clear ground rules for the spatial planner. The Layers Approach seems to offer a robust methodology for spatial planning. This contribution presents the background of the Layers Approach, adds some critical notes and proposes an amendment: the Network Approach, connecting different spatial scales. After the presentation of a typology of networks a preliminary overview of the dynamics of transport networks is given. The spatial relevance of information and communication technology (ICT) networks, that support transport networks, is discussed. Nodes are presented as links between infrastructure networks and occupation patterns. The paper concludes that actors, dealing with regional spatial plans in a decentralized planning system, have to acquire an in-depth knowledge of the technology, economy and governance of current networks and the qualities of the substratum, which form a conditioning and stimulating framework for the spatial planning of urban and regional areas.  相似文献

Spatial clusters contain biases and artifacts, whether they are defined via statistical algorithms or via expert judgment. Graph-based partitioning of spatial data and associated heuristics gained popularity due to their scalability but can define suboptimal regions due to algorithmic biases such as chaining. Despite the broad literature on deterministic regionalization methods, approaches that quantify regionalization probability are sparse. In this article, we propose a local method to quantify regionalization probabilities for regions defined via graph-based cuts and expert-defined regions. We conceptualize spatial regions as consisting of two types of spatial elements: core and swing. We define three distinct types of regionalization biases that occur in graph-based methods and showcase the use of the proposed method to capture these types of biases. Additionally, we propose an efficient solution to the probabilistic graph-based regionalization problem via performing optimal tree cuts along random spanning trees within an evidence accumulation framework. We perform statistical tests on synthetic data to assess resulting probability maps for varying distinctness of underlying regions and regionalization parameters. Lastly, we showcase the application of our method to define probabilistic ecoregions using climatic and remotely sensed vegetation indicators and apply our method to assign probabilities to the expert-defined Bailey's ecoregions.  相似文献
