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.     

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.     

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.     

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.     

Global cities in Global Commodity Chains: exploring the role of Mexico City in the geography of global economic governance

In this article I assert that global cities are critical nodes in Global Commodity Chains because it is from them that producer services are provided. I explore forward linkages of producer service firms in Mexico City, showing that there are important service flows to companies responsible for the globalization of the 'Mexican' economy. Based on this finding I also indicate reasons why Mexico City is 'on the map' of global cities and of Global Commodity Chains. I argue that both access to local knowledge and close contact to clients are key factors. A third issue dealt with is the position of Mexico City in the geography of governance of commodity chains. The analysis suggests that it is useful to break up global city functions into the management of the world economy and into its command and control, because Mexico City is certainly a place for the former, while the scope of influence exercised from the city is rather limited.     

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.     

Integrating world cities into production networks: the case of port cities

In this article we analyse the location patterns of firms that provide specialized advanced producer services (APS) to international commodity chains that move through seaports. Such activities can take place in world cities or in port cities. The analysis of APS location patterns in port cities provides a good opportunity to integrate the study of world cities into the framework of Global Production Networks. Based upon our empirical findings, we conclude that while port-related APS activities predominantly follow the world city hierarchy, a number of port cities stand out because they act as nodes in global commodity flows and as centres of advanced services related to shipping and port activities. Based on these empirical findings we address future avenues of research.     

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.     

City networks and commodity chains: identifying global flows and local connections in Ho Chi Minh City

Any analytical framework for understanding actual forms of the intensified incorporation of cities into the world economy needs to go beyond the exclusive focus on advanced producer services, which is characteristic of most of the World City Network (WCN) approach. Simultaneously, an account of the role of advanced producer services will strengthen Global Commodity Chain (GCC) analysis. A combination of the literatures on WCN and GCC can contribute to a broader conceptualization of the connections and connectivities of global cities. In addition, a combined approach will improve our understanding of globalization processes within many so-called 'third-world' cities that are experiencing booms in export-oriented industrialization and in migration from rural hinterlands as they are being integrated into Global Commodity Chains. We illustrate our argument with insights from GCC analyses of the electronics industry located in Ho Chi Minh City and the agricultural sector in its rural hinterland, the Mekong Delta.     

The new geography of global civil society: NGOs in the world city network

Recent research on the geography of NGOs in Global Civil Society yearbooks has emphasized a north-west European bias. This has been taken to imply that global civil society is but a pale geographical shadow of the power concentrations in global economy and governance. Using an interlocking network model and data on 74 global NGOs with offices across 178 cities, NGO connectivity values for cities show that there is a ‘global South’, especially sub-Saharan African, geographical bias. Nairobi is the most connected world city with respect to NGO activities. This marked contrast to recent received wisdom implies a diffuse network power relationship. To the extent that global NGOs reveal the new geography of global civil society in a space of flows, these results support a positive interpretation for NGOs contributing to an emancipatory global agenda.     

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.     

A cultural economy perspective on service sector migration in the global city: the case of Hong Kong

This article argues that in order to fully understand the geography of labour migration to global cities, it is necessary to consider economic forces in conjunction with mediating socio-cultural influences. Support for this argument is based on an examination of the pattern of migration to Hong Kong, a city which plays a significant role in the world economy.
Reported here are the results of an analysis of recently released 1996 by-census data, and the authors' interviews with foreign domestic workers in Hong Kong. These findings have shown that highly skilled immigrant workers were drawn largely from developed countries, the main sources of inward investment in this city, while less skilled immigrants were drawn from less developed neighbouring labour markets.
While the geographical pattern of immigration followed broadly that predicted from Hong Kong's position in the world economy, the results have revealed that cultural influences such as language and social networks are also important in shaping the economic roles of migrant workers.     

Home,city and diaspora: Anglo–Indian and Chinese attachments to Calcutta

This article is about the city as home for people living in diaspora. We develop two key areas of debate. First, in contrast to research that explores diasporic homes in relation to domestic homemaking and/or the nation as home or ‘homeland’, we consider the city as home in diaspora. Second, building on research on transnational urbanism, translocality and the importance of the ‘city scale’ in migration studies, we argue that the city is a distinctive location of diasporic dwelling, belonging and attachment. Drawing on interviews with Anglo–Indian and Chinese Calcuttans who live in London and Toronto, we develop the idea of ‘diaspora cities’ to explore the importance of the city as home rather than the nation as ‘homeland’ for many people living in diaspora. This leads to an understanding of the importance of migration and diaspora within cities of departure as well as resettlement, and contributes a distinctively diasporic focus to broader work on comparative urbanism.     

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 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.     

Divergence of the world city system from national economies

This study shows that the position of cities in the world economy has diverged from national economies. Using data from 2016, we evaluate a network of 12,802 cities formed by the location decisions of 24,355 firms in terms of their point centrality, and show that the inter-city and inter-national systems have measurably decoupled, disrupting the previously-observed pattern in which the most powerful cities in the world city system were located in core countries, "mid-level" cities were in the semi-periphery,and the least powerful cities were in peripheral countries. Our findings support predictions that globalizing cities would diverge from national economies and that globalization would generate a new global geography that transects long-standing cleavages in the world system.     

For Refugees,the Road to Employment in the United States Is Paved With Workable Uncertainties and Controversies

Drawing on data—including survey responses, interviews, documents, and participant observation—collected during a 26‐month ethnography of refugees in a northeastern U.S. city, I examine how recently arrived refugees create and access new employment opportunities. I utilize actor‐network theory (ANT) to examine refugees' linkages as emerging, temporal, and fluid. I empirically trace the drawing together of, and interaction among, individual refugees, formal organizations, new cultural ideas, and a myriad of material objects. I examine the connections between the uncertainties about actors, action, and agency that point to the need to understand society as sociomaterial networks. I analyze the controversies that are deployed in an emerging assemblage as the refugees entered the paid workforce in the United States. I am guided by a broad question: How are meaning, knowledge, and facts that come to make up a network actually made, maintained, remade, and, sometimes, undone? I demonstrate that putting assemblage to work offers insights into the ways in which heterogeneous elements come together in often unanticipated ways to create stable, even if temporary, employment networks for refugees in the United States.     

The Social Construction of Romantic Relationships in Adolescence: Examining the Role of Peer Networks,Gender, and Race*

Romantic activity is a social psychological phenomenon. Gender, race, and peer networks are key contexts for understanding the social construction of this behavior as gender‐ and race‐based norms structure feelings and behaviors that define “appropriate” romantic activity and peer networks serve as incubators of this activity. With a nationally representative sample of adolescents (N= 8510) drawn from the National Longitudinal Study of Adolescent Health, this study explored the linkages among peer networks, conceptions of idealized romantic relationships and actual romantic relationships, and the ways in which gender and race moderate these associations. Several characteristics of peer networks predicted adolescent attitudes about romantic behaviors as well as actual romantic behavior. Moreover, the linkages among peer networks, romantic attitudes, and romantic behaviors varied by race.     

Staying connected under fire: Effects of individual roles and organizational specialization on the robustness of emergency-phase communication networks

Communication network connectivity is central to organizational performance, but maintaining connectivity can be difficult during periods of disruption. During the World Trade Center (WTC) disaster of September 11th, 2001, both emergency response-specialized organizations and organizations without such specialization forcibly adapted to a radically altered environment. Their dynamic communication networks necessarily entailed trade-offs between competing demands for efficiency and robustness to disruption. Of particular importance is whether organizations concentrated activity within a small number of “hub” nodes, and whether those with existing coordinative roles were critical to maintaining connectivity. We examine these questions by analyzing seventeen organizational communication networks in the WTC disaster. We find that organizations maintain connectivity through relatively small numbers of coordinators, but the realization of institutionalized coordinative roles depends upon organizational context. Further, we find distinct patterns of robustness, with the removal of key players leading to mass isolation in specialist networks versus a gradual pattern of failure in non-specialist networks. These results suggest that organizations responding to disruptions within their usual domain of operations will be more likely to retain institutionalized roles when building emergent networks, although this increases the network's fragility in the event of the loss of one of those coordinators. Organizations responding to novel threats may reconfigure more radically, limiting vulnerability to the loss of institutionalized—but not emergent—coordinators.     

Introduction to the special issue: after trust

‘Trust’ has long been seen as critical to the success and durability of trading networks, and conceptualized as a positive moral sentiment that is embedded in shared kinship, ethnicity or friendship, or in shared frameworks of morality. Other recent studies of business communities suggest that the ability to work in settings characterized by pervasive mistrust is a key factor in the development of commercial acumen and a determinant of success. Here, the authors argue that a focus on trust and mistrust, and an underlying concern with ethics and morality, can obscure equally critical factors that inform the durability of trading networks. They offer ethnographic accounts of different inter‐Asian trading networks active in the city of Yiwu, which is one of China's most dynamic and diverse ‘international trade cities’. Yiwu is home to the largest wholesale market of small commodities in the world, and attracts traders and merchants from across the planet; more than 12,000 foreign traders are also resident in the city. The authors of the articles presented here analyse the durability of these networks in relation to broader geopolitical processes and contexts. They argue that success often depends on the ability to negotiate geopolitical shifts and the fault lines of political identity. They trace traders’ efforts to create institutions that allow them to withstand geopolitical transformations. They also document the ability of trading networks to operate flexibly across different social fields, showing that resilience often depends on the ability to navigate and profit from shifting relations between economic, political and familial domains.
