Local Firms and Global Reach: Business Air Travel and the Irish Software Cluster

We study the external linkages of clusters through a typology of forms of temporary proximity (from foreign business meetings to co-located projects). We suggest that here business air travel and information and communication technologies have given significant advantages to small firms. We investigate these arguments through a case study of the Irish software industry in Dublin. Comparing indigenous and multinational corporation (MNC) firms confirms that indigenous firms are as travel intensive as MNCs but are linked to fewer destinations. We conclude that air travel enables small firms to go global without the support of collective cluster institutions.     

The Role of Domestic and International External Cluster Linkages Explored on the Example of Buyer–Supplier Relations in Learning Regions: A Cross-Functional Assessment

This paper analyses three levels of interaction among firms: regional, domestic and international, the analysis relying on cross-functional supplier evaluations by their customers. The statistical analysis reveals that indeed three groups with different evaluation results can be distinguished. Contrary to expectations, though, regional suppliers were not better evaluated than domestic suppliers, while international suppliers scored weakest. Cross-functional differences in assessment were found, which urges researchers to collect cross-functional data for cluster assessment. We conclude that external linkages play an important role in understanding clusters and that the domestic level has to be taken into consideration of an analytical entity of its own.

Managing the Global–Local Dimensions of Clusters and the Role of “Lead” Organizations: The Contrasting Cases of the Software and Medical Technology Clusters in the West of Ireland

The purpose of this paper is to investigate “leading” firms in an industrial cluster to understand how the balance between global and local dimensions of the cluster can be managed. Two cases of industry clusters, the software and medical technology clusters in the west of Ireland, are employed to examine how certain organizations can occupy a “lead” position and how—if at all—such organizations generate an agglomerative effect in a cluster. In the case of the medical technology cluster, the study shows that when large firms enact a leading role by influencing the technology trajectory of the region and stimulating the local dynamic, they can generate agglomerative effects, thereby enhancing the relevance and sustainability of clusters. Most significantly, it shows how leading organizations act as an important facilitator in connecting the global and local dimensions of clusters even in the absence of extensive local formal linkages. At the same time, the case of the software cluster reveals that the presence of large organizations alone does not inevitably stimulate such a clustering effect and emphasizes that appropriate characteristics and conditions need to be in place. Overall, while the study substantiates previous research on the significance of temporary and organized forms of proximity, it also shows the value that permanent geographical proximity can have, thereby contesting recent research that downplays the relevance of the clustering institution (e.g. Lorentzen, A. (2007) The geography of knowledge sourcing—A case study of Polish manufacturing enterprises, European Planning Studies, 15, pp. 467–486; Wickham, J. & Vecchi, A. (2008) Local firms and global reach: Business air travel and the Irish software cluster, European Planning Studies, 16, pp. 693–710).

External Ties and the Reduction of Knowledge Asymmetries among Clusters within Global Value Chains: The Case of the Ceramic Tile District of Castellon

Classical industrial districts' literature is not focused on the role played by external ties but gives more importance to the local districts' endogenous development. Global value chains connect clusters to other external agents through external linkages and constitute a framework to analyse the complex inter-linkages between clusters and other external agents. In the field of the external ties and the global value chain approach Academia is primarily focused on the ties which link clusters in developing nations to global markets, although global value chains also consider connections between clusters in similar activities and even when both are located in developed nations. Thus, external linkages are mainly performed by multinational enterprise (MNE) affiliates which play fundamental role of knowledge diffusers and absorbers in the process of knowledge exchange throughout global value chains. The work examines the process of knowledge exchange between clusters through external ties using the global value chain approach. For this purpose, empirical work is conducted with 22 face-to-face interviews to provide a case study about a leading cluster in the global ceramic tile industry. Results show that the basic knowledge to successfully compete is locally originated, although it can be complemented with global knowledge learnt or generated in other territories. MNE affiliates bridge structural holes through external ties and reduce knowledge asymmetries within global value chains. External ties on network-based governance chains exist, matter and affect clusters allowing upgrading even between developed nations.

区域技术创新的非正式制度和联系:经济地理学的视角

众多区域技术创新的研究案例表明,非正式的制度和联系是区域技术创新成功的重要因素。本文回顾了经济地理学在区域技术创新的非正式制度和联系方面研究的相关理论和研究成果,发现"创新环境"、"非贸易相互依赖"、"地方传言"和"企业衍生"等理论虽然提出并探讨了区域技术创新的非正式制度和联系的属性和特征,却对这种非正式制度和联系的形成原因和影响机制的分析相对较少,对其空间尺度的研究也过度集中于区域尺度。由于当前我国大多数区域内部企业之间的创新联系大部分仍以非正式联系为主,因此对于区域技术创新的非正式制度与联系的形成原因、影响机制及其对创新绩效的影响的进一步研究,将具有非常重要的理论和实践意义。

ECONOMIC GEOGRAPHY WITHIN AND BETWEEN EUROPEAN NATIONS: THE ROLE OF MARKET POTENTIAL AND DENSITY ACROSS SPACE AND TIME*

ABSTRACT In explaining the uneven spatial distribution of economic activity, urban economics, and new economic geography (NEG) dominate recent research in economics. A main difference between these two approaches is that NEG stresses the role of spatial linkages whereas urban economics does not do so. We estimate simple versions of these two views on economic geography and also establish if the relevance of spatial linkages varies across aggregation levels or time. For our sample of 14 European countries and 213 corresponding regions, we find that spatial linkages are more important at the country level and that its relevance varies across time.     

The brokerage role of supporting organizations inside clusters: how does it work?

The objective of this research is to examine in depth the brokerage roles that supporting institutions play in conducting local business and applying technical knowledge inside clusters. We identify three main roles: a coordination role, characterized by the efforts that organizations play in internally coordinating themselves and establishing a shared institutional framework; an interconnector role, where organizations foster communication along the value chain of the industry; and a gatekeeper role that allows organizations to connect cluster members with external networks. Results obtained in the Toy Valley cluster provide evidence that each kind of supporting organization tends to specialize in specific roles, since universities are best for a coordination role with regard to technical knowledge while private organizations are key for vertical communication and coordination. Similar results were obtained when analysing the extra-cluster contacts that these organizations develop as gatekeepers, as they tend to establish specific communication conduits with similar alters in external networks.     

Multi-sectoral Cluster Modelling: The Evaluation of Scottish Enterprise Cluster Policy

This article describes the ex post cluster evaluation framework being developed by Scottish Enterprise. It focuses primarily on the macro level evaluation and, in particular, on the use of multi-sectoral modelling techniques to identify the effects of cluster policy on key indicators such as gross domestic product (GDP), unemployment and competitiveness. The Scottish Input-Output (I-O) table is a key element in this approach. The strengths and weaknesses of I-O data, both as a basis for this analysis and as a means of identifying important intra-cluster linkages are explored. Further, the article describes methods for visual representation of the linkages identified using such a method.     

空间扩容背景下长三角城市群陆路交通联系时空演化

城市群空间扩容有赖于城市间交通联系的强化。文章以县域为研究单元,探讨长三角城市群由16个设区市扩容至26个设区市,各单元经由陆路交通与中心城市及设区市市区的交通联系时空演化。结果显示：(1)空间扩容引致公路通达时间有所增长,但趋于均衡化发展。(2)扩容后普速铁路网络通达时间明显增加,尽管连通度有所提升,但连通强度明显下降;高铁网络通达时间显著低于普铁网络,且连接指数显著高于普铁网络,中心城市在高铁网络中优势突出。(3)主要得益于高速铁路发展,扩容后陆路可达性及其均衡性均有所提升,交通发展很好地支撑了城市群扩容;受城市群扩容及陆路交通发展的共同作用,可达性格局发生了明显变化,长江的阻隔效应更为明显。
