Some evidence of thinking at this larger scale has been detected by Rodrigue and Hesse (2007). Efforts to refine and expand these ideas could usefully follow approaches to spatial strategies that have been developed by urban planners dealing with the spread of their metropolitan areas. The assessment of corridor development versus intensification of existing nodes versus new centres in more distant locations that exercise the minds of logistics planners is a sectoral example of the broader urban management approaches being applied in these large urban regions. In addition there may be a need for the ‘‘creativity in financing new infrastructure and implementing new technologies and policies” cited by Leinbach and Capineri (2007, p. 270). Both will call for new institutional structures that are now seen as the critical element in managing modern urban development (Keating 2001; Healey, 2006; Kreukels et al., 2003). Third, the research was designed to assess whether measures of physical logistics activity reflect the level of development of global city functions. In the absence of data on the actual location of firms and details of their functions in each city, the analysis relied upon the statistical relationship between the rank (and hence the commercial, financial and administrative importance of a global city) and logistics role of each global city region. The research found that less than 50% of the variance in logistics activity in a global city logistics region was associated with an index measuring the rank of the rank of its global city. Exploring those results for categories of city exposed the infrastructure issue outlined above, while at the same time showed that many middle and lower ranked global cities with basic infrastructure were important in logistics activity. Hence, infrastructure may be a necessary but not sufficient explanatory factor of the performance and concentration of freight activity in the main global logistics regions. Rodrigue and Hesse (2007, p. 106) have observed ‘‘It is not only simple infrastructure provision that makes firms go to a certain area but the ability of regions and cities to cope with the extraordinary demand for flexible, timely and cost efficient physical distribution”. It is may be that the newly-minted and special role that out-sourced logistics companies now play in the handling of freight might be a critical part of the link between global city functions and logistics. These new roles reflect the way many other services have evolved and developed over recent years, moving from a position as a final step in a production process to a central and innovative function, one that can shape production outcomes (Bryson et al., 2004). This change emerged from the outsourcing of functions from firms, which, in turn, created specialist service providers. One effect of this shift has been a geographic concentration of service firms. That has been illustrated within the broad category of producer services, and, in particular, in the finance sector. It may well apply to logistics services. If so, understanding the location of out-sourced logistics service companies might provide some new insight into reasons for the uneven nature of freight activity among cities. Just as the idea of a ‘‘buzz” has been used to account for the concentration of innovative activity in the cores of global cities (Storper and Venables, 2004), so the local expressions of the ‘‘global ‘buzz’ that has become logistics” Wang et al. (2007, p. 1) might provide insight on the role played by global logistics regions in world freight movement. Olivier and Slack (2006) have created one path into this new perspective by clarifying the role and significance of multi-national terminal operators as a new dimension in the services of sea freight. This perspective recognizes the steady evolution of logistics services through the standard out-sourced model (labeled ‘‘third party provider” in logistics analysis) to ‘‘fourth party provider” where the logistics service company becomes fully integrated into the production process of the client firm, running warehouses, in some cases dictating production outputs (from a knowledge of stock levels) and in other circumstances handling returns and servicing problems. The global city logistics regions used in this research may be very attractive places for these complex service companies. That is because access to competing gateways could provide lower freight and loading cost due to competition, provide greater flexibility in operations and possibly ensure a wider set of destinations served. Access to both sea and airports would be an additional advantage for those logistics firms with clients needing both sea and air transport at different times and for different products. Finally, the complex logistics tasks might begin to draw upon other services just as the finance sector has done as it has become more specialized. Again global logistics regions could be attractive as their core business city will have the array of producer services that might be needed to underpin the operation of logistics. It is these places that might evolve into what Wang and Cheng (2009) has labeled ‘‘global supply chain management centres”. A key question here is whether these new logistics service providers shape the direction of physical flows, favouring some ports and airports because of the depth of supporting services, even if their clients may not necessarily be in that region. This is a potentially interesting area of research. The research has provided some additional insight into the function and vitality of global city regions, showing not only that logistics is an important activity, but that levels of that activity might be a useful means of differentiating the development of these regions. In effect, the acknowledgement of the role of both sea and air freight in a region has confirmed that it makes sense to think of global cities as logistics cities, as Easterling (2004) suggested. A further aspect step in this research could involve the analysis of the internal spatial development of these regions. Logistical activities could be creating or re-vitalising some of the nodes that Hall (2001) has found contributes to the poly-centric character of these regions. Alternatively the transport activities might be dispersed among fringe green-field sites, so accelerating the spread of the region. Local case studies of this aspect are planned as a follow up to this paper. Finally, this paper set out to utilize sea and air freight data simultaneously in an innovative effort to capture the breadth of logistics activity. Apart from the need to bridge two separate sets of thinking and analysis this approach faced serious technical questions in measurement. The approach used was the Global Logistics Index which made it possible to merge sea and air freight data into a readily interpretable form, and provide a foundation for more refined thinking on the patterns that were detected. It is however a crude summation of two separate data sets and will need refinement if it is to be applied in other issues. That refinement could involve some way to weight sea and air freight prior to any merge of their numbers. Drewe and Janssen’s (1996) efforts to differentiate between tonnage and value-added in ranking transport activity could be a useful starting point here.
