Impact of Polycentric Urban Systems on Intra-regional Disparities: A Micro-regional Approach

From the normative perspective of EU regional policy, polycentric spatial development has been seen as an effective tool to overcome regional disparities since the adoption of the European Spatial Development Perspective. However, the impact of a polycentric spatial structure on equal spatial development is ambiguous and still waits for its clarification. This paper examines the relationship by focusing on the local scale, where medium-sized towns play a crucial role as local centres in everyday human lives. Using functional regions of the Czech Republic, this paper defines polycentric urban systems at the micro-regional scale. Subsequently, the level of mono/polycentricity is compared with intra-regional disparities. Based on the results of the analysis, it can be argued that the connection of polycentricity with balanced spatial development is strongly determined by selected indicators. However, the findings do not provide evidence about the strictly positive impact of polycentricity on intra-regional disparities. In a light of these results, the conclusion is rather sceptical about the unique role of polycentricity in spatial development and due to the lack of similar studies, further research is recommended.     

EUROPEAN BRIEFING: Polycentricity in European spatial planning: from an analytical tool to a normative agenda

The notion of polycentricity is gaining widespread currency in both academic and professional debates. It has opened its way in the spatial policy documents of the European Union and member states alike, and has become one of the key components of the integrated spatial development strategy promoted by the European Spatial Development Perspective (ESDP). Whilst polycentricity is increasingly shaping the spatial policy discourses both in the Commission and in member states, the precise meaning of the term has remained elusive. The first two sections of this article aim to unpack the concept of polycentricity, trace its origin and its development and clarify the confusion over its multiple interpretations at various spatial scales. The third section of the article explains how the concept of polycentricity which has traditionally been used as an analytical tool to explain an existing or emerging reality is now increasingly being used to determine that reality. This is based on the analyses of the use of polycentricity within the European spatial planning framework and in particular the ESDP. Here, the article raises a number of questions regarding the promotion of the polycentric urban regions as one of the ESDP's key policy options for a balanced territorial development across Europe.     

Measuring Regional Cohesion Effects of Large-scale Transport Infrastructure Investments: An Accessibility Approach

Transport infrastructure is considered one of the main policy instruments to achieve the cohesion goal, although the inclusion of cohesion effects in assessment methodologies is scarce and uneven. Although most cohesion studies are constrained to the analysis of regional disparities in economic indicators, this approach can be broadened to include other regional performance indicators. One of these indicators could be accessibility measures, from the point of view that accessibility, representing a competitive advantage of locations, constitutes a “desirable good” closely related to the welfare of each region. This paper suggests using changes in the spatial distribution of accessibility as a proxy to assess regional cohesion effects of transport infrastructure investments. However, as the conclusions taken depend heavily on the formulation of the accessibility measure, we recommend computing a set of accessibility indicators and analysing their results in a complementary way. The proposed methodology is tested by assessing regional cohesion effects of the large-scale road and rail transport infrastructure investments carried out in Spain in the period 1992–2004. The results obtained show that cohesion has improved for the road mode, while regional disparities have increased for the rail mode. This paper identifies the main factors driving this final cohesion effect and explores the strengths and weaknesses of the different accessibility indicators that were considered. The approach suggested in this paper has the potential to be applied in transport planning processes, and may eventually complement existing strategic assessment methodologies.     

基于GIS的县级尺度交通可达性研究——以陕西省为例

本文以陕西省为例,采用加权平均出行时间指标,对县级尺度的到区内节点、火车站、主要干线公路和机场的交通可达性分别进行了评价,结果表明:陕北的东北部、西北部,陕南的东南部各方面交通可达性表现都很差,西安及周围临近县市各方面则表现良好。通过对到区内节点可达性和三种方式的区外交通可达性加权求和得出的区域交通可达性进行的研究表明,陕西形成了以西安与其周围临近县市组成的片状可达性低值区,可达性良好;陕北的大部分及陕南的南部可达性差;陕西省整体可达性分布不均衡。陕西省今后交通建设的重点应是提高区域交通可达性的均衡性。     

Questioning Polycentric Development and its Effects. Issues of Definition and Measurement for the Italian NUTS-2 Regions

Polycentric development is a widely used term both in academic research and in the normative agenda. However, its theoretical foundations and economic implications are still unclear and the concept of polycentricity still does not have a shared definition or a shared measurement method. The aim of this study is two-fold. First, it defines and measures polycentricity at a NUTS-2 regional level, by comparing functional and morphological methods. Second, in the light of the role assigned to polycentric development in terms of policy, the study investigates the relationships between the degree of regional polycentricity and the key economic variables of performance, namely, competitiveness, social cohesion and environmental sustainability. Our main finding was that functional and morphological methods lead to similar results. In addition, we find a correlation between polycentricity and a more unequal income distribution and a higher level of productivity, especially when polycentricity was measured in functional terms. No stable correlations were found between polycentricity and measures of environmental sustainability, such as land consumption and greenhouse gas emissions.     

Polycentricity – one concept or many?

This paper aims to discuss polycentrism and its implications. Polycentricity plays a key role in EU Cohesion Policy and has done so since 1999 when the notion was included in the European Spatial Development Perspective. Politically, it emerged as a key tool because of its ability to fuse together the two primary and conflicting perceptions of spatial–economic development, cohesion and competitiveness. No agreed definition of polycentricity exists. Furthermore, different actors and disciplines define polycentrism differently. The absence of a concise and coherent definition makes it difficult to measure polycentricity. Moreover, several studies have concluded that it is difficult to identify empirical evidence to support the positive claims made in its name. Polycentrism is assumed toolbox to reduce regional disparities, but polycentric countries display higher regional disparities than monocentric countries. Polycentric countries do not perform better than monocentric countries with regard to competitiveness and GDP/cap. As such, this paper concludes that not only does the political meaning of polycentricity struggle over aims with the inherit dichotomy at its heart, it also struggles in terms of basic credibility.     

What “Is” Territorial Cohesion? What Does It “Do”?: Essentialist Versus Pragmatic Approaches to Using Concepts

The question, “what is territorial cohesion” has reverberated through European spatial policy since the publication of the European Spatial Development Perspective in 1999. Over the last 10 years, the European Spatial Policy Observation Network (ESPON) has made many efforts to define and measure the concept of “territorial cohesion”. Many such attempts assume that a policy concept must be defined in order to be “operationalized”. Or, in other words, that we must determine what the concept is before we can determine what it can or should do. This paper challenges this assumption in two parts. In the first, I review a number of ESPON projects to show how complex and uncertain these essentialist definitions have become. In the second, I analyse a number of national, regional and local government responses to the 2008 Green paper. I show that, whilst a clear and coherent definition has not been established, this concept is already operationalized in different policy frameworks. Bringing this together, I argue that users of such concepts ought to approach the issue differently, through a pragmatic line of enquiry: one that asks what territorial cohesion does, what it might do and how it might affect what other concepts, practices and materials do.

The European spatial development perspective and North‐West Europe: application and the future1

The European Spatial Development Perspective (ESDP) is the product of a north‐west European planning tradition. This article discusses the role of north‐west European concerns, in particular the use of the concept of polycentricity, in the making of the ESDP, and the application of the ESDP in the North‐west European Metropolitan Area (NWMA), more in particular in Germany, the UK, The Netherlands and Belgium. The article also explores the future of spatial planning as regards north‐west Europe. Much will depend on how Community policy will adapt to the enlargement of the European Union. However, it seems certain that existing member states, in particular those in north‐west Europe will see their share in the structural funds evaporate. This may give added significance to INTERREG IIIB respectively to the successor of this Community Initiative. In addition, concepts like territorial cohesion and territorial management may become functional equivalents to that of spatial planning, for which the Community is said to have no competence.     

Evolution of the Territorial Coverage of the Railway Network and its Influence on Population Growth: The Case of England and Wales, 1871–1931

Abstract

The introduction of the railway network brought with it an unprecedented improvement in accessibility. In this work, the authors analyze the evolution of the territorial coverage of the railway network and its influence on the uneven distribution of population. To carry out this research, they used comparable data on total population obtained from census records relating to civil parishes of England and Wales, taken at 10-year intervals from 1871. The hypothesis that they wished to test was that good access to a railway station was related to significant increases in population. This exercise provides a better understanding of regional variations in population growth and allows the authors to identify current differences between urban and rural areas that have resulted from their historical evolution.     

Operationalizing a contested concept: indicators of territorial cohesion

European territorial policies increasingly refer to broad goals such as sustainability, well-being and cohesion. For their operationalization as political goals, there is a need to create indicators. But how can an indicator be meaningful in relation to a complex concept that is not well defined? If the creation of an indicator is primarily aimed at quantifying a concept and making it more operational, in the case of a contested concept (such as territorial cohesion), the process of building indicators also helps stabilize it, allowing a potential decontestation. A participatory constructivist approach – as used by the ESPON project Indicators for Territorial Cohesion (INTERCO) – is considered to be the most suitable for building indicators of contested concepts. While ensuring computability of the indicators, it allows more flexibility and reconciles the different meanings of the concept in order to stabilize it. Ultimately, the validity of indicators of contested concepts lies in pragmatic criteria: usability, usefulness and use.     

Measuring Polycentricity and its Promises

Even a decade after the concept of polycentric development became popular and increasingly widespread in Europe as a normative policy stance allegedly leading to cohesion and competitiveness, its empirical basis is still rather weak. This is partly due to a lack of conceptual clearness, which makes its measurement difficult. This research briefing synthesises the results of two recent ESPON projects that aim to create a quantitative measurement of the extent of polycentricity of national urban systems, as well as the links they find between polycentricity and economic and social objectives. Both approaches have their limits and have been, and can be criticized from various perspectives. Some suggestions on how to proceed with this research agenda are presented.

European Spatial Planning Between Competitiveness and Territorial Cohesion: Shadows of Neo-liberalism

This paper analyses the use of the concept of territorial cohesion in policy documents produced by the European Union. It is an idea celebrated in community documents, such as cohesion reports, the Territorial Agenda of the European Union and the Green Paper on Territorial Cohesion; after more than a decade of political debate, the concept is about to gain a legitimate institutional role, after being included in the Lisbon Treaty, and is among the competences that the EU shares with other member states. At first, territorial cohesion seems to oppose the logics of neo-liberalism by reinscribing welfare problems and policies in spatial terms. However, using the analytical framework of cultural critics, and intending cohesion to be a discourse carried on by a community of European scholars and policymakers, the research will discuss the conceptual relationship between competitiveness and territorial cohesion in European policies and narratives.     

European Union Competition Policy and the European Territorial Cohesion Agenda: An Impossible Reconciliation? State Aid Rules and Public Service Liberalization through the European Spatial Planning Lens

The territorial and spatial planning impacts of European Union (EU) economic and competition policies have remained under-researched in the field of European spatial planning, in contrast to other EU policy fields. This briefing explores how two elements of the EU competition policy, the regulation of “state aid” and the liberalization of “services of general interest (SGI)”, have significant implications for the pursuit of the objective of territorial cohesion through spatial planning and territorial development policies at different scales. The paper first reviews the development of the concept of territorial cohesion in the EU discourse and policy agenda since the mid-1990s, as well as the contribution of public services (Services of General Interest, or SGI in EU jargon) to it. It, then, reviews how the EU state aid rules and liberalization policies affect the state's ability to intervene (i) in support of sub-national territories which are lagging behind or suffering decline, and (ii) in the provision of public services across the national territory, specifically in peripheral regions or areas where the provision is not catered for by the market. The conclusion of the paper outlines the additional challenges to the pursuit of territorial cohesion in the EU posed by the post-2008 economic crisis and suggests avenues for future research.     

Planning Small Regions in a Larger Europe: Spatial Planning as a Learning Process for Sustainable Local Development

An enlarged Europe is addressing the challenge of territorial cohesion on the basis of a disciplinary and operative framework formed by a number of evolving documents and provisions to be applied and developed at different administrative and planning levels. Rapid and profound changes have occurred in previous decades as far as institutional framework, the role of actors and issues to be tackled are concerned, within a re-scaling process of territorial governance. In this context, small territories can take advantage of European funds, but experience a hard confrontation with the market economy and supra-local visions, use of resources and infrastructure projects. A decisive role, in many countries, has been gained by regional authorities, which must mediate among various territorial levels, institutions and actors involved in a multilevel governance process. The paper focuses on spatial and regional/territorial planning processes among the European dimension, Member States and regions, on the basis of a case study conducted in Northern Italy. The aim is to determine the role of European spatial planning as a “learning machine” [Faludi, A. (2008) European Territorial Cooperation and Learning, disP 172, (1/2008), pp. 3–10.] able to support processes of mutual learning and cooperation, overcoming the attitude of compliance to upper level schemes and financial programmes rather than innovating usual procedures and territorial planning.

The Rise of Territorial Governance in European Policy

The notion of territorial governance has relatively recently emerged onto the European policy agenda, and often used in relation to the concept of territorial cohesion. To date, the notion has been understood and conceptualized in various ways and has been defined rather loosely when invoked. This paper examines how the notion is used and understood in European policy debates. It questions whether the notion is different to general concepts of governance and multi-level governance. Three specific characteristics are suggested that might distinguish territorial governance from other types of governance: (i) managing territorial dynamics, (ii) assessing territorial impacts and (iii) delineating policy boundaries.     

From smart growth to European spatial planning: a new paradigm for EU cohesion policy post-2020

Formally initiated in 1989, European Union (EU) cohesion policy (ECP) has since passed through a series of metamorphoses, along its five programming periods, while becoming the most financed EU policy. As its name indicates, its initial goals were earmarked for promoting economic and social cohesion, following the intentions expressed in the Single European Act. Since then, from a policy strategy intervention point of view, ECP has shifted into a financial tool to promote investment for growth and jobs. In the meantime, European spatial planning (ESP), which had its debating pinnacle with the release of the European Spatial Development Perspective, by 1999, has declined in interest and narrowed into a novel notion of Territorial Cohesion. In this challenging context, this article analyses the implementation and main impacts of ECP and proposes a new strategic paradigm, built around a novel ‘ESP’ vision, backed by the main pillars and dimensions of territorial development and cohesion. More particularly, we suggest that the current rationale for a smart, sustainable and inclusive growth could instead fuel an alternative strategic design based on a cohesive and sustainable development vision: green economy, balanced territory, good governance and social cohesion.     

Linking polycentricity concepts to periphery: implications for an integrative Austrian strategic spatial planning practice

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.
