The duality of world cities and firms: comparing networks,hierarchies, and inequalities in the global economy

Much of the research on globalization conceives of the global economy as structured by networks among places, while separately organizational research has examined the role of networks among firms in structuring competition, collaboration, and cooperation. In both cases, position and centrality within the network confers certain advantages and disadvantages, the distribution of which defines a hierarchy. In this article, I explore the idea of dual networks of world cities and firms, then use Breiger's approach to define two such networks: one among 313 world cities, another among 100 advanced producer service firms. Comparison of the degree of inequality in the hierarchies implied by these networks suggest that world city hierarchies are steeper than firm hierarchies (that is there is greater inequality among cities). Thus, even under conditions of footloose global capitalism, place still matters: where a producer is located has more impact than who provides support services.     

Understanding the position of end nodes in the world city network: using peer city analysis to differentiate between non‐hub cities

In the current debate on the world city network and inter‐city connectivity, a large number of cities, particularly in developing countries, have received limited attention. Despite a growing interest in emerging market cities, many scholars still focus on the more affluent parts of the global economy. In an attempt to redress this imbalance, I present an assessment for use on cities that are not at the centre of the network; but what we consider ‘end nodes’. I build my argument on Taylor's interlocking model for assessing city connectivity and zoom in on the types of networks that non‐hub cities create through their inter‐linkages with so‐called peer cities in the same economic sector. I take these ego networks as a starting point and then lead the argument on to view city networks from a non‐hub perspective. This allows me to identify the existing linkages between different peer cities within as well as between selected city networks. The renewable energy business in India puts this argument to an empirical test. My findings confirm that this way of looking at city connectivity allows one to assess specifically for city end nodes and thereby contribute to a more nuanced understanding of the world city network.     

The cliquishness of world cities

Abstract Through an exploratory analysis of the world city network, we confront the dearth of studies on inter‐urban networks on a global scale. In the first section, we outline how a formal theoretical specification of the world city network as a social network has guided an extensive data gathering effort. Through this specification it becomes possible to apply standard techniques of network analysis to world cities. In the second section we outline a framework within which to explore the complex patterns that arise from the formal specification of the world city network. The conjectural use of connectivity, world city cliques and clique‐by‐clique comembership is then used in the third section as the input to an exploratory analysis of the measures of connectivity at different thresholds. The main findings are the two city dominance of the New York–London dyad, and the observation that inter‐city links at the global level retain an important regional dimension. Exemplary cases are the thorough interrelatedness of North American, Pacific Asian and European world cities.     

The worldwide maritime network of container shipping: spatial structure and regional dynamics

Port and maritime studies dealing with containerization have observed traffic concentration and dispersion throughout the world. Globalization, intermodal transportation, and technological revolutions in the shipping industry have resulted in both network extension and rationalization. However, lack of precise data on inter‐port relations prevent the application of wider network theories to global maritime container networks, which are often examined through case studies of specific firms or regions. In this article, we present an analysis of the global liner shipping network in 1996 and 2006, a period of rapid change in port hierarchies and liner service configurations. While we refer to literature on port system development, shipping networks, and port selection, the article is one of the only analyses of the properties of the global container shipping network. We analyse the relative position of ports in the global network through indicators of centrality. The results reveal a certain level of robustness in the global shipping network. While transhipment hub flows and gateway flows might slightly shift among nodes in the network, the network properties remain rather stable in terms of the main nodes polarizing the network and the overall structure of the system. In addition, mapping the changing centrality of ports confirms the impacts of global trade and logistics shifts on the port hierarchy and indicates that changes are predominantly geographic.     

How manufacturing industries connect cities across the world: extending research on ‘multiple globalizations’

In this article, I concentrate on a macro‐level analysis of inter‐urban linkages in a ‘world city network’. Empirical research on the formation of a world city network has mostly concentrated on global service providers. Yet, globally operating manufacturing firms also choose distinct urban regions throughout the world as locational anchoring points. In this article, using social network analysis, I present the first global‐scale analysis of how manufacturing firms connected cities across the world (in 2010). To detect the differing ‘sectoral profiles’ and nodal centralities of cities functioning as geographical hubs of transnational production networks, it is necessary to analyse the network structure of distinct industrial subsectors within the global urban system. The data collected for analysis cover 120 top global firms from three manufacturing subsectors, of which two are analysed in more detail than the third. I then compare the nodal centralities of cities included in these subsectors' global networks with the GaWC research on the producer services sector that has been at the centre of previous analyses of the world city network. The comparison reveals the cities' differing positioning within ‘multiple globalizations’. The aim of the article is to extend research on world city networks.     

Exploring the joint dynamics of intercity internet and corporate networks: a stochastic actor‐based modelling approach

In this article, I show one possible solution to synthesis dynamics in multiple intercity networks. I adopt a stochastic actor‐based modelling approach to explore the co‐evolution of an intercity corporate network of 57 globalized advanced producer service firms across 93 cities, and another intercity internet network between these 93 cities, for the period 2004–2010. Stochastic actor‐based models (SABMs) help to connect interactions among cities and firms on the local scale with empirically observed networks on the global scale. My analysis accounts for the co‐evolution/interdependence among multiple world city networks (WCNs) and associated network changes in individual WCNs with exogenous city‐related covariates and endogenous local network structures.     

The spatial politics of the past unbound: transnational networks and the making of political identities

In this article I consider the relations between historical and contemporary forms of transnational political networks. I contest accounts that counterpose a networked present against a more settled and bounded past, arguing that this contrast rests on a problematic temporalization of difference in the construction of political identities. I consider how this temporalization produces particular accounts of relations between space, politics and identity. Drawing on the insurgent imaginative geography of resistance in C. L. R. James's The Black Jacobins, I argue for a focus on the dynamic geographies of connection formed through transnational networks. I develop this position through a discussion of the relations of the London Corresponding Society, formed in London in 1792, to transnational routes of political activists, organizational forms and ideas. This account highlights the multiple political identities crafted through transnational political networks. I conclude by outlining elements of a ‘usable past’ for contemporary counter‐global struggles.     

Transnational Municipal Networks in Climate Politics: From Global Governance to Global Politics

In a multilevel and multicentric governance arena, pathways and mechanisms of influence are several and non-state capacities for technical leadership and norm entrepreneurship prove more significant than is the case within a strictly multilateral framework. Among actors with such capacities are municipalities, which multiply their influence through horizontal and vertical relationships. Transnational municipal networks present opportunities for both intermunicipal dialogue and the pooling of global influence, highlighting the presence and influence of the city in the world. This paper examines the collective response of some cities to climate change, exploring the place of cities in global environmental politics through analysis of two transnational municipal networks: the International Council of Local Environmental Initiatives' Cities for Climate Protection and the International Solar Cities Initiative. The article addresses the following questions: How might municipal efforts toward a climate-stable future be significant to the larger issue of ecological justice in global environmental politics? Might cities be able to redefine the rules of the game and take a stand on ‘inefficient’ norms? After briefly accounting for the relationship between cities and the world, the article characterizes technical leadership as a legitimizing force of and in global environmental governance and norm entrepreneurship as a potential source of contestation and subversion in global environmental politics. The paper describes what cities are globalizing, in terms of pollution, environmental degradation, and risk, and in terms of management and politics. Finally, the article explores the possibility that emerging horizontal and vertical relationships, intermunicipal relationships, and relationships between cities or networks of cities and other scales of governance potentiate legitimizing roles for cities in climate governance and subversive roles in climate politics.     

The multipolar regionalization of cities in multinational firms' networks

This article identifies the most cohesive multi‐polar regions of the network of world cities, which differ from the unipolar centre–periphery model largely created by the high weight of central city connections. We use a community detection algorithm that outlines the high densities of city networks (in relative weights). Various patterns of industries and services, which are divided into two skill levels, are identified. We use a global database of the network of 1.2 million direct and indirect ownership links between the 800,000 subsidiaries of the top 3000 multinational groups in 2013, allowing us to build four comparable networks of 503 metropolitan areas. Comparing the obtained partitions with continental, regional and economic benchmarks, classes of cities partially correspond to free trade zones (FTZs) but exhibit interesting cross‐continental patterns. A few cities, changing their classes according to the activities, are discussed in the light of the multinational firms' strategies.     

Attending to the world: competition,cooperation and connectivity in the World City network

World Cities are acknowledged to be a key aspect of globalization. In many accounts, these cities are depicted as rivals in a global marketplace, their economic success a result of their competitive advantage. However, what has not been fully acknowledged is their connectivity and, in addition, the time and effort taken by specific ‘attendants’ to produce the World City network. Accordingly, this article aims to advance understanding of World City network formation by developing a conceptual model that focuses on four major attendants (firms, sectors, cities and states) that enact network formation through two nexuses —‘city‐firm’ and ‘statesector’— and two communities —‘cities within states’ and ‘firms within sectors’. The utility of this model is demonstrated by drawing upon interviews conducted in offices of 39 advanced producer service firms in banking and law. These interviews were undertaken in three World Cities (London, New York and Singapore) in the wake of the East Asian financial crisis, an event that challenged the consistency of the World City network. Showing how attendants sought to maintain and transform the World City network at this key moment of crisis, we conclude that studies of city competitiveness ultimately need to focus on the cooperative work that sustains global networks.     

The world according to iTunes: mapping urban networks of music production

In this article, I present a social network analysis that explores and maps relational urban networks of production within the global recorded music industry. Within the analysis, recorded music albums are viewed as temporary market‐based projects that bring together teams of skilled creative workers in recording studios across the globe. New tools and techniques for networking studios in geographically distant locations give mobile musically creative workers the ability to coordinate musical recordings on a global scale, resulting in new relational geographies of music production. An innovative approach is taken to the social network analysis to assess the connectedness of cities and determine the centrality and power of cities within networks of production for three major Anglophone digital music markets. The result is a mapping of the relational urban networks of music production as indicated through the interdependencies between projects, studios and local urban agglomerations.     

Racial formation,inequality and the political economy of web traffic

ABSTRACT

Few studies attempt to demonstrate whether and how systemic racial inequality might form on the web. I use racial formation theory to conceptualize how race is represented, and systematically reproduced on the web, and how both may reveal forms of racial inequality. Using an original dataset and network graph, I document the architecture of web traffic, and the actual traffic patterns among and between race-based websites. Results demonstrate that web producers create hyperlink networks that steer audiences to websites without respect to racial or nonracial content. However, user navigation reflects a racially segregated traffic pattern; users navigate to racialized versus nonracialized websites (and vice versa) more than what would be expected by chance. These results, along with disparities in website traffic rankings, provide evidence of, and demonstrates how a race-based hierarchy might systematically emerge on the web in ways that exemplify disparate forms of value, influence and power that exist within the web environment.     

中心城市建设综合交通系统的经验、启示与对策——以伦敦、广州为例

通过分析伦敦的交通规划、建设、运营与管理措施,发现我国中心城市的严重交通拥堵主要源于落后的城市交通规划理念,大量引入多层高架公路进入市中心而忽视轨道交通建设,对公交优先存在认识上的误区和执行不力;城市公共交通工具营运各自为政,缺乏有效的协调与接驳;运营的低效率和管理不当,由此造成了典型的“大城市病”。根据后现代主义城市建设思想,结合当前中心城市公共交通体系建设的现状,提出了广州市综合交通体系建设的12项具体措施。     

Contact,the feature pool and the speech community: The emergence of Multicultural London English

In the multilingual centres of Northern Europe's major cities, new varieties of the host languages are emerging. While some analyse these ‘multiethnolects’ as youth styles, we take a variationist approach to an emerging ‘Multicultural London English’ (MLE), asking: (1) what features characterise MLE; (2) at what age(s) are they acquired; (3) is MLE vernacularised; and (4) when did MLE emerge, and what factors enabled this? We argue that innovations in the diphthongs and the quotative system are generated from the specific sociolinguistics of inner‐city London, where at least half the population is undergoing group second‐language acquisition and where high linguistic diversity leads to a heterogeneous feature pool to select from. We look for incrementation ( Labov 2001 ) in the acquisition of the features, but find this only for two ‘global’ changes, BE LIKE and goose ‐fronting, for which adolescents show the highest usage. Community‐internal factors explain the age‐related variation in the remaining features.     

Youth Jury Policy Deliberation: Towards a Fair and Responsible Internet

Young people aged between 12 and 17 across three major British cities — London, Leeds and Nottingham — were invited to play the role of ‘jurors’ on a case where ‘the Internet was put on trial’. The recommendations reported in this paper are intended to improve digital experience and online safety as contributions to policy. These recommendations derive from the ‘youth jurors’ policy deliberations designed to encourage young people to reflect on their digital experience and collectively develop their own problem definitions and solutions.     

Moving images: world cities,connections and projects in Sydney's TV production industry

World city research concerned with connectivity has tended to focus on advanced producer service firms and on selected North American and European cities; the prevailing methodology has been quantitative. In this article I answer the call to ‘go beyond counting’ by bringing together a project‐based enquiry — on a TV mini‐series Mary Bryant— with a more conventional assessment of network connectivity. The inclusion of a practice‐centred approach to this case study adds the performative data to the network, highlighting the actions and processes of those involved in maintaining the city networks. Furthermore, I demonstrate how this method of analysis is more suited to the study of project‐based cultural industries and highlight the role of Sydney in the global television industry — a city hitherto under‐explored in world city literature.     

Social Movement,Action and Change: The Influence of Women's Movements on City Government in Mumbai and London

This article reports on a research investigation into gender and local government in Mumbai in India and London in England. In both these cities female representation at the political level stands at around one third, achieved in London slowly in recent years and in Mumbai more rapidly through the adoption of a quota, or seat reservation system, implemented in 1992. In considering the experience of the women concerned it is argued that their presence and aspirations have been influenced through the networks of their respective women's movements, operating through civil society and the local state. In considering the ways in which they organize and manage the duties of office and their gendered identities, as well as in their focus on the most disadvantaged in their communities and in their dealings with others, the part played by social movements in influencing change is examined.     

Making connections: Global Production Networks and World City Networks

This article offers a sympathetic critique of recent attempts to forge a dialogue between Global Commodity Chain (GCC) and World City Network (WCN) approaches to global economic change. While broadly supportive of the endeavour, we make three observations about this ongoing project. First, we question the utility of emphasizing the common roots of these approaches in World Systems Theory given that both have subsequently moved into new epistemological terrain and, additionally, that the language of core and periphery seems ever less pertinent to global economic realities. Second, we seek to highlight the potential dangers of essentializing the global system as one that is primarily shaped by certain kinds of connections – namely the intra-firm relationships of advanced producer service firms – between certain kinds of cities – namely the leading tiers of global cities. Third, we point to the need to expand the interpretations of relationality within global networks to include a wider variety of actors, particularly beyond the corporate realm, and to explore the dynamic power relations between those actors. We also discuss the methodological challenges of expanding the purview of research in this way. This commentary has been stimulated by the articles in the special issue of Global Networks on 'World City Networks and Global Commodity Chains'.     

The structure of global centrality measures

The aim of this article is to identify and analyse the logic and structure of centrality measures applied to social networks. On the basis of the article by Borgatti and Everett, identifying the latent functions of centrality, we first use a survey of personal networks with 450 cases to perform an empirical study of the differences and correspondences between degree, closeness and betweenness centrality in personal networks. Then, we examine the correspondences between the three global indicators in each type of centrality: the maximum value, the mean value and the hierarchy or centralization. The results provide a better understanding of the centrality indicators of networks and the reality that they express in an empirical context.     

Characterizing air pollution patterns on multiple time scales in urban areas: a landscape ecological approach

Quantifying the spatiotemporal patterns of air pollution in urban areas is essential for studying ecological processes, environmental quality, and human health in cities. To adequately characterize or monitor air pollution patterns, one important issue is scale because the concentrations of air pollutants are temporally dynamic and spatially heterogeneous. Our research addresses the scale issue in air quality monitoring and analysis by considering the following research questions: (1) How does the spatial pattern of ozone change with the temporal scale of analysis? (2) How does the spatial pattern of PM₁₀ change with the temporal scale of analysis? (3) What implications do these scale effects have for designing and evaluating air pollution monitoring networks? We systematically examined these questions based on data from official air pollution monitoring networks in the Phoenix metropolitan region, Arizona, USA. Our results showed that spatial patterns of both ozone and PM₁₀ may change substantially with the temporal scale of analysis. Ozone patterns at broader (but not finer) temporal scales were more consistent across years, and exhibited a more uniform, regionalized pattern. PM₁₀ patterns were less consistent across years than ozone, and exhibited a more localized effect. Spatial patterns of PM₁₀ also varied seasonally. Our study demonstrates that it is critically important to consider the temporal and spatial scales in designing or evaluating air monitoring networks in particular and in conducting air pollution research in general.
