Transaction links through cities: ‘decision cities’ and ‘service cities’ in outsourcing by leading Brazilian firms

Most world city studies focus on where the provision of advanced producer services takes place, but in this study the location of the service clients are also taken into account. Production-service transactions are identified as links between ‘service city’ and ‘decision city’ (client HQ) and classified as intra-city (where a firms uses local (same city) services) and inter-city which may be domestic or foreign depending on whether the client uses services in or out of the country. Sampling the leading firms in Brazil, 218 transaction links are described and analysed in terms of cities, firm sectors, ownership and market. The analyses are used to inform a rereading of gateway city functions that takes into account the concentration/dispersal nexus in economic globalization. Thus, whereas the dominance of Sao Paulo in the Brazilian economy is confirmed, this is not interpreted as a simple gateway function with this one city ‘articulating’ the national economy into the world economy. A much more complex situation is revealed with by-passing of the gateway also much in evidence. The conclusion is that this shows concentration and dispersion of economic activity happening simultaneously in Brazil.     

Migrants, markets and multinationals: competition among world cities for the highly skilled

Urban areas compete with one another for people, goods, capital, ideas and other inputs of economic activity. Under the rubric of globalization, instead of only maintaining or improving the initial stock of assets in a city, the power of a place to attract outside flows of economic activity from elsewhere is increasingly important to economic development. Similarly, global or world cities are characterized as the command and control points through which these global economic flows operate. In response to the heightened mobility of highly-skilled labor across national borders, research has begun to examine the role of international human capital as an economic flow. This paper will examine the role of places in determining where the highly-skilled go in the global economy by viewing global city command and control functions as requiring unique labor flows. By reviewing the evidence found in the literature, we can better understand the potential for urban areas to compete for highly-skilled labor in the global economy. Known indicators of place attractiveness are assessed to examine the relationship between the economic trajectories of cities and their labor requirements. Cities are situated between firms and states as the key place-based actors which influence the mobility of highly-skilled labor. Finally, the paper also examines measurement issues and methodological problems in creating indices of world cities as well as explores possibilities for new research.     

Knowledge,influence, and firm-level change: A geographic analysis of board membership associated with Canada’s growing and declining businesses

Clarification of the factors that drive business expansion and contraction is among the most important topics that can be addressed by research in economic geography and related disciplines. This study analyzes the development of Canadian business by examining the connection between firm-level growth and decline and elite knowledge and influence connections that Canadian businesses use to link themselves to other corporations and cities nationally and globally. The research focuses on the inter-firm and inter-city linkages embodied in the boards of directors of Canada’s leading corporations. Corporate directorships have an important geographic dimension, as firms invite people from a variety of places and backgrounds to serve on their boards. This study finds that board member selection practices among Canadian firms can be linked directly to business growth and decline. Benchmarking board composition against firm expansion and decline in terms of inflation-adjusted annual revenue change over the 1991–2006 period, this study shows that growing Canadian firms are associated with directors from a much broader range of national and international cities than firms that experienced decline over the same period. Firm growth in Canada thus appears to be related to boards encompassing diverse members from national and international locations, while firm decline appears to be associated with boards including more local and regional members. The conclusion interprets the implications of board member diversity and suggests that broadly-based boards can play a role in encouraging firm growth through access to elite knowledge and influence networks.     

World cities and territorial states under conditions of contemporary globalization II: Looking forward, looking ahead

The influence of globalization on the future study of political geography is investigated through research on world cities. It is argued that political geography, like most social science, has been excessively state-centric in its organisation and that this will not help in understanding new transnational processes within contemporary globalization. Study of the state should not be abandoned, of course, but it must be set in a new context where much politics takes place beyond the state. This is illustrated through using the world city network as an alternative spatial framework to the world political map. The political geography of the twenty first century will have to incorporate traditional concern for political areas with new concerns for power networks in more subtle geographies than heretofore.     

Transnational elites in global cities: British expatriates in Singapore's financial district

Skilled international migration is as an important process of both contemporary globalization and the global city. The establishment of a transnational elite of expatriate labour in international finance plays a vital part in the accumulation of capital within international financial centres (IFCs). Expatriate labour has become a major determinant of the IFC, creating financial capital through complex social relations, knowledge networks, practices and discourses. The principal argument being made in this paper is that expatriates are major agents in the accumulation and transfer of financial knowledge in the IFC, and that such processes are undertaken through expatriate global–local knowledge networks and other social practices. The paper is divided into three major parts. Following a discussion of transnational elites as expatriates in global cities, which also conceptualises their contribution to the spatialization of financial knowledge networks, the empirical study investigates the working, social and cultural knowledge networks and practices of British expatriates in Singapore. Finally, the paper revisits the conceptual work on transnational elites and suggests that expatriates were deeply embedded in global–local relations in the workplace and the business/social sphere through interaction with local ‘western educated/experienced' Singaporeans, but were disembedded from the local in the home and other household social spaces due to the invisibility of the local population in their interactions. Both the theoretical and empirical analyses suggests that expatriates are flow in the Castellian spatial logic of the network society.     

Identifying China’s leading world city: a network approach

This paper reports our research on China’s world cities. Formal network analysis of air passenger linkages for recent years among China’s most populous cities and among many of the world’s largest cities allows us to identify the country’s leading world city from among the leading Mainland candidates, Beijing, Shanghai and Guangzhou. We theorize our findings about China’s world cities in relation to both global forces (and China’s increasing entanglement with them) and the policies and actions of the national state. We examine the national and global urban network through a longitudinal, two-level analysis of airline passenger travel for four time points between about 1990 and 2005. We show that Beijing was China’s leading world city at the beginning of the time period, a status it lost nationally in as early as 1995, and then globally 10 years later. On the other hand Shanghai became China’s leading world city, and it acquired this status first nationally in 2000, and then globally in 2005. The changing status of the Chinese capital corresponds to the country’s increasing involvement with the capitalist world economy. Shanghai’s ascendance as the leading world city in China may indicate that global forces have come to play an increasingly important role relative to that of the developmental state.

Barcelona's planning strategies: from 'Paris of the South' to the 'Capital of West Mediterranean'

Planning strategies in Barcelona are linked to its capital city aspirations. Like other European cities, capitals and non-capitals, Barcelona throughout the course of the 20th century has drawn upon a number of different planning strategies, directed towards reinforcing its prestige at both a national and international level. During this period Barcelona has sought to become Spain's second capital, the cultural capital, the industrial capital, capital of Catalonia, capital of the West Mediterranean, etc. Always in competition with Madrid, the aspirations of capital status ranking have been ambiguous. The dream of the great monumental Barcelona of the start of the century tried to emulate the European capital cities (especially Paris). By contrast more recent strategies emphasise the new role that Barcelona can play within a south-west European macro-region. The subject raised in this paper then is two-fold. On the one hand the continuity or not in the capital aspiration starting from the recuperation of Catalonia's autonomy, with its corresponding urbanistic and architectonic connotations. On the other hand the originality and analogies between strategies carried out in Barcelona, in relation to other European cities, capitals and non-capitals.     

Environmental geology of ancient Greek cities

Man-environment relations in the ancient Greek world, as now, were complex interactions. To understand them, we need to study a range of physical features and man's impact on the setting. The underlying geological reality of this area is karst, which is widely distributed, dominating Greece, the southern half of Turkey, and southern Italy and Sicily, where the Greco-Roman cities that we study were located. Year-round water from karst springs was important because of scarce rainfall, intense evaporation, and infertile soil—none under human control. Examples from the Greek mainland (Corinth), an Aegean island (Rhodes), Turkey (Priene), and Sicily (Syracuse) are selected and described to suggest the way that karst water potential played an important role in site selection and development. A wider look at criteria for urban location and a new classification of urban patterns help to revise conventional understandings of these ancient cities. In conclusion, some modern findings about the interaction between city and setting suggest new research agendas for geologists and engineers, ancient historians and archaeologists, and water policy makers—preferrably working together.     

Introduction: immigrants and transnational experiences in world cities

Today, in the early 21st century, goods, information, services, financial capital and human beings are flowing across national borders at an ever-accelerating rate. In this context, transnationalism has become a key paradigm in the study of international migration and urbanism. This theme issue on “Immigrants and transnational experiences in world cities” explores these new trends in contemporary international migration, with respect to transnational communities and geographies, in articles grouped according to four themes: international migration and world cities; highly-skilled and low-skilled immigrants; economic impacts; and immigrant experiences in world cities.     

A site of transnationalism in the “Ungrounded Empire”: Taipei as an interface city in the cross-border business networks

This paper explores the dynamics of the economic development of Taipei City under conditions of globalization. Although Taipei City had undergone rapid industrialization and exploited the rural-urban division of labor since at least the 1960s, the city’s economic base changed dramatically after 1980. Initiating a process of industrial restructuring, the nation state encouraged high technology industries to help upgrade Taipei City’s role within global production chains. It was the transnational connection that kept regional growth within high ‘value-added’ activities. Instead of relying on a few major transnational corporations as the key agents of internationalization, Taipei City transformed itself into a node for high-technology knowledge, which connected the city with high-technology hubs elsewhere, and to Silicon Valley in particular, through transnational technical communities. At the same time, companies headquartered in the city extended their production chains across the Taiwan Strait to locate production facilities in the major coastal cities of mainland China. In consequence, Taipei City became a nodal city in these cross-border connections. These developments illustrate the limits of global city discourses which fail to pay sufficient attention to the role of developmental states and transnationalism in the process of global transformation.     

Corporate knowledge transfer via interlocking directorates: a network analysis approach

This paper explores spatial changes to knowledge transfer by Canadian and American corporate networks from 1976 to 1996. Results support facets of a World Cities approach for Canada. Toronto lies at the top of the hierarchy, while Montreal, Calgary, and Vancouver fall into a third tier of specialized regional cities. The American knowledge network also possesses facets of the world cities approach. The world city, New York, lies at the top of the hierarchy. Further down, Chicago is a specialized national city, while a number of regional centers have emerged to play a larger role over the twenty-year study period. A third tier of cities has emerged to play the critical role of specialized regional cities. This geographical phenomenon can be explained in terms of industry, headquarters locations, and network maturity. Finance, insurance and real estate, as well as “other manufacturing” are three sectors of the economy that are prominent in the network. In Canada, these sectors have increasingly centralized in Toronto while decentralizing in the United States. Similarly, the headquarters location of American firms is decentralizing from New York and Chicago, while Canadian headquarters continue to be centralized in Toronto. Finally, results indicate that the potential for knowledge transfer depends upon maturity of the system under investigation. The mature US network with a large pool of qualified business individuals is better suited for knowledge transfer at the regional level. The Canadian network is less developed and not appropriate for regional systems of knowledge transfer. The result is a Canadian corporate knowledge threshold that encompasses the entire country while a number of much smaller corporate knowledge thresholds appear across the United States.     

Strategic globalizing centers and sub-network geometries: A social network analysis of multi-scalar energy networks

Over the past three decades, a multitude of studies have examined the relational properties of corporate networks as a proxy for analyzing interurban hierarchies and structures. While this has been important in illuminating the nature of global connectivity, a significant conceptual lacuna exists in understanding how a multi-scalar analysis of interurban networks informs a more complete understanding of the geographies of globalization, and how cities within these networks act as regional globalizing centers. Building upon the theoretical and methodological foundations of ‘world city network’ (WCN) research, this paper investigates the corporate networks of the energy industry as a historic driver of globalization using social network analysis from an Australia geographical perspective. Globally and nationally scaled energy networks derived from the Platts and Australian Securities Exchange (ASX) corporate lists are used to explore the convergence of nationally and globally articulated networks, and identify cities instrumental in the globalization of the national industry sub-networks. These are strategic ‘globalizing centers’ which, in contradistinction to ‘global cities’ or ‘world cities’ as broad classifications, play nuanced roles in anointing industry-specific circuits of capital and information. The analysis of two complementary yet distinct networks provides theoretical insight into how scale plays an integral role in defining/articulating interurban relations.

Relationality/territoriality: Toward a conceptualization of cities in the world

The paper contributes to the conceptualization of cities in the world by first outlining the conceptual and empirical challenges of theorizing the urban/global nexus in both relational and territorial terms. It argues that the most useful and appropriate approach to understanding contemporary urban governance in global context is to develop a conceptualization that is equally sensitive to the role of relational and territorial geographies, of fixity and flow, of global contexts and place-specificities (and vice versa), of structural imperatives and embodied practices, in the production of cities. In order to illustrate the benefits of this conceptualization, the paper will apply it to the case of how downtown development is governed in many contemporary cities. The role of the Business Improvement District (BID) program and New Urbanist planning models in shaping downtowns will be examined in terms of: (1) how and by whom these models are developed in a global-relational context and are set in motion through scaled circuits of policy knowledge and (2) how the mobilization of these models are conditioned by their territorialization in specific spatial and political economic contexts. The paper emphasizes that the ‘local globalness’ of policy models like BIDs and New Urbanism and their consequences for cities can best be understood through a combined focus on relationality and territoriality.     

‘We are managing!’ Uncertain paths to respectable adulthoods in Accra, Ghana

Studies have shown that the life experiences and future prospects of young people in many parts of the world today are more complex and less predictable than those of past generations. This has led to a recognition of the need to reconsider the conceptual frameworks applied in youth studies. Thus far, research within geography has mainly focused on young people’s paths to adulthood in the Global North or on particularly vulnerable children’s lives in the Global South. In this paper an approach based on the ‘social navigation’ of ‘vital conjunctures’ is adopted to explore the complex ways in which young people in Ghana navigate their way through life in a city marked by economic hardship and neo-liberal reform. The stories of three young people are presented to show the variety of life conditions, the complex social positions they occupy and their various and shifting future imaginations. The actions of these young people are steered by prevailing cultural ideals and social expectations of what a desirable and respectable future entails and by the actual space of possibility in the urban space they move through. It is argued that achieving respectable adulthoods in present-day Accra is a complicated and convoluted journey involving the careful management of social relationships.     

内陆河流域城镇发展的历史过程与机制——以黑河流域为例

城市的起源与形成是一个极其复杂而漫长的过程,是诸文明要素积累凝聚、从量变到质变的过程.黑河流域的城市大致经历了五个发展阶段:秦汉以前的城市萌芽,两汉时期的奠基期,十六国时期、隋唐时期的第二高峰期,宋以后的衰落期,直到明清以后城市再度复苏.在这一变化过程中,移民屯垦、兴修水利、农牧业的消长与进退、人口迁移与聚集、地缘政治和自然环境的变化是城镇发育与成长的主要驱动力.其中,又蕴含了两个相互交错的正负效应:汉民族的西扩—统一的国家—稳定的地缘政治关系—移民屯垦—兴修水利—农业繁荣—气候暖湿—城镇发展;少数民族东进—地方割据—复杂动荡的地缘政治环境—牧业扩张—气候干冷—沙漠化扩大—城镇衰退.其实质是在特定的地理环境和民族分布格局下,对优势生存空间的争夺.     

State University and Russian Academy of Sciences as contributors to the innovative restructuring of Moscow

Both University and Academy of Sciences have traditionally been important economic actors of the Russian capital city, although their research activity was covered mostly from the federal budget. Links with Moscow city authorities have been regulated from the top (Communist party directives etc.) and channelled within focused research programs, hardly financed extra to stable budget salaries. At the present stage, when more and more financial mechanisms are involved, their links with Moscow Government are based on initiative from the bottom and look rather like a survival strategy than as a real motivated innovative activity. Academy seems to be more successful in establishing network of contract research for the city: in 1993– 95 out of 83 proposals 55 have been financed through the cooperation program Academy to Moscow, Moscow to the Academy (most of them in the field of environment, industry, transport, cultural heritage and healthcare). Out of 159 university proposals only 9 were selected and none really financed. In reality links between scientists and Moscow government are much more intensive than officially registered due to their participation in expert commissions, consultancies and research contracts, developed on the basis of informal networks. University science park is a special case-study in this paper, providing an example of a successful innovative activity in Moscow. The main barriers for the use of innovative potential of the main Russian fundamental science centres in Moscow are 1) the lack of economic innovative policy by the city authorities, 2) weakly developed mechanisms of bringing the results of fundamental research into practice, 3) rising taxes, other intermediate charges and bureaucratic obstacles, making any kind of research activity for the benefit of Moscow economically disadvantageous, 4) low synergy effect of technologically innovative research, 5) conservatism of a big part of the personnel (especially in the University) and negative attitude to any kind of commercial activity in cathedrals of science. Nevertheless, there are evident signs that the role of Academy and University in creation of innovative millieu in Moscow is growing, both as producing new knowledge and labour force training, and as centres of direct enterpreneurial activity (see Castells and Hall 1994).     

The binational cities of Dover and Calais and their region

This paper analyses the question of cities that are localised at each part of an international border. We take as an example the two cities of Dover and Calais and look at if they can be considered as binational cities, because they have been recently connected by a tunnel, the ‘fixed link’, and because since 1993, the inner state borders of the European Union have disappeared. It determines firstly if these two towns have been brought closer by the construction of the Channel tunnel and if specific ties are linking these two towns. The article scrutinizes actions taken under INTERREG funds under the general framework of the creation of the ‘Transmanche Region’ and its extension towards a Euroregion to sort out these two cities joint involvement. Finally, it checks if this new area could lead to cross-border activity either for work or tourism and leisure purposes that could conduct the cities of Dover and Calais toward a new type of relationship, premises of a binational city. This revised version was published online in July 2006 with corrections to the Cover Date.     

The potential and prospect for global cities in China: in the context of the world system

Over the last two decades, accompanying their rapid economic development, many `mega-cities' in China have devoted themselves to changing their relationships to the global economy and some have aimed at attaining global (world) city status as a key future development goal. This paper examines the relationship between global (world) city status and the emerging world economic system, and discusses the intense competition between `mega-cities' in the Asia-Pacific region that Chinese cities will face in the 21st century, especially after the Asia financial crisis. It also explores the potential and possibility of achieving global or world city status in China. The main arguments are that only Hong Kong, Shanghai and Beijing have the possibility to attain leading positions in the global urban system in the future. Post-1997, it has been very important for the Chinese government to find a way to coordinate the functions of Hong Kong and the other major cities which allows them to operate smoothly together under quite different political systems. Finally, the authors analyse the relationships between these three metropolises and suggests some possibilities for coordinating their roles in the global urban system.
