Indonesia's rapidly growing mega-urban regions of Jabodetabek (Jakarta Extended Metropolitan Region), Bandung and Surabaya each have a large and socio-economically heterogeneous population. The 2000 Census presents evidence that substantial spatial and socio-economic inequalities in under-five mortality risk exist in these mega-urban regions. Differences in patterns of birth attendant utilization likely contribute to these inequalities. Multilevel multinomial logistic regression of data primarily from the National Socio-economic Survey (SUSENAS) reveals that use of a skilled birth attendant is highly associated with mother's education. Highly skilled assistance is more related to the enabling factor of household expenditure quintile. The findings provide evidence for efforts to help reduce inequalities in early age mortality risk through improved access to trained birth assistance, in addition to other interventions.  相似文献

This paper analyses the spatial patterns of young (<10 years) digital firms in Germany between 2008 and 2017 on county level. Determinants of firm birth locations as well as relocations are considered jointly to understand differences in location choices within firms' life cycles. I match commercial register data of 107,321 firms with county-level administrative data to capture local characteristics. Using an OLS model with fixed effects, I find that the local knowledge base—that is, universities, research institutes, and colocated incumbents—are significant key determinants of digital firm birth when controlling for a host of local characteristics. My results indicate that for five firms per 1000 inhabitants, there is around one firm birth. Second, using a fixed effects gravity model for the analysis of relocations, I find that the most dominant explanatory factor for firm relocation across specifications is distance, that is, relocation costs. Relocation flows are more than twice as high to neighboring counties relative to other locations which shows that digital firms are not as footloose as their business model may suggest. Jointly, my results reflect economic activity's regional persistence, particularly for new firms. My paper provides evidence for policies targeting homogenous digital clusters based on strong colocation and that digital economic activity is not shifted over long distances, but the regional entrepreneurship capital is crucial for local growth.  相似文献

Studies in evolutionary economic geography have found that knowledge spillovers, crucial for the development and maintenance of clusters, tend to flow between sectors that are related via similar inputs and/or outputs. Thus, there is a growing body of literature stating that industrial variety within clusters is beneficial for economic growth, whereby local industrial diversity sparks creativity, new ideas and innovations. Within this context, the Irish Maritime and Energy Resource Cluster (IMERC) is a diverse, multisectoral cluster. Using an Input–Output table this paper examines the intra-cluster linkages, as well as the relatedness in terms of inputs and outputs across the four IMERC pillars: Marine Energy; Shipping, Logistics and Transport; Maritime Safety and Security; and Yachting Products and Services. This analysis found that although IMERC has weak intra-cluster linkages, the four pillars share a high number of related inputs and outputs. Based on this analysis, IMERC has the potential to develop into a strong maritime cluster.  相似文献

Spatial Cluster Detection in Spatial Flow Data   总被引:2,自引:0,他引:2       下载免费PDF全文
As a typical form of geographical phenomena, spatial flow events have been widely studied in contexts like migration, daily commuting, and information exchange through telecommunication. Studying the spatial pattern of flow data serves to reveal essential information about the underlying process generating the phenomena. Most methods of global clustering pattern detection and local clusters detection analysis are focused on single‐location spatial events or fail to preserve the integrity of spatial flow events. In this research we introduce a new spatial statistical approach of detecting clustering (clusters) of flow data that extends the classical local K‐function, while maintaining the integrity of flow data. Through the appropriate measurement of spatial proximity relationships between entire flows, the new method successfully upgrades the classical hot spot detection method to the stage of “hot flow” detection. Several specific aspects of the method are discussed to provide evidence of its robustness and expandability, such as the multiscale issue and relative importance control, using a real data set of vehicle theft and recovery location pairs in Charlotte, NC.  相似文献

ABSTRACT

In this paper we examine the geographic patterns of employment growth and employment polarization in small and medium-sized cities (SMCs) in Denmark during the rise of the new economy. The geography of employment polarization in Danish cities is examined using register-based employment data on occupations and wages divided into the public and private sectors in the period 1993–2006; it therefore covers a long period of transformation and growth in the Danish economy. We conclude that employment growth is characterized by employment polarization combined with growth in low- and high-wage employment and a decline in medium-wage employment. However, these patterns of polarization differ across the public and private sectors, as well as by geography. While local labour market (LLM) size, city position and city specialization influence the geography of private-sector employment growth and polarization, municipal population and composition influence the geography of public-sector growth patterns across wage levels. Finally, public and private employment are positively associated within SMCs, predominantly driven by the positive association between public employment and private-sector low-wage employment. However, public employment is not associated with an increase in private low-wage employment in more remote areas.  相似文献

In this study, we aim at evaluating the role of path-dependent and past-dependent forces in the historical trajectory of clusters. For that purpose, we study the life cycles of four of the main industrial clusters in the Basque Country (paper-making, electronics and information and communication technology, maritime industries and aeronautics) and analyse the factors that account for the origin, development, maturity and, if so, decline of those clusters, considering factors related to both cluster dynamics and the regional environment. Our analysis shows that the existence of a life cycle does not imply a straightforward growth path. Clusters follow multiple growth patterns in their development. The heterogeneity of growth patterns may be, in some cases, due to different initial conditions. However, despite similar initial conditions and/or resource endowments and opportunities for development, we can observe heterogeneous evolutionary patterns. Clusters react differently to the same external shocks (e.g. international demand, global competition and technological change) and evolve differently according to their capabilities.  相似文献

In this paper, we study how globalization impacts on the structure and governance patterns of value chains and on the resilience of local clusters. We study the value chains related to two Basque (Spain) companies in the wind energy industry, Iberdrola and Gamesa, and the local cluster to which they belong. We find that firms within the cluster have different types of relationships with lead companies depending on their competences and the complexity of their products. As a consequence, firms also present different potential for growth and/or resilience: some have the capacity to internationalize their operations and/or shift to the offshore wind market, others are vulnerable to competition from providers in the emerging countries. Against this context, we discuss how the cluster responds to these challenges and the role of policy.  相似文献

City officials are continuously working to attract airlines willing to fly to new destinations. The inherent expectation is that a more extensive aviation network stimulates economic growth. This paper investigates empirically the causal implication of this hypothesis. Using data on nonstop flights by origin and destination over the period 1984–2013, we propose a new measure for a metropolitan area's connectivity to the national aviation network. We then use this measure to investigate its contribution to local economic development, as captured by the growth in population, in total employment, in per-capita income, and new firm entry. To ensure causality, we use instrumental variable methods that exploit geography and destination airports growth as a way to capture the exogenous variation in the likelihood to add new travel routes. Our results suggest that a metropolitan area's air connectivity, resulting from an expansive local aviation network, has a positive effect on population, on employment and on the number of businesses established in that location.  相似文献

ABSTRACT

Many rural regions in Europe used to be characterized by weak economic performance and negative population development. While in a long-term perspective this is not any more valid for large parts of Western Europe, a number of rural regions face persistent population decline. By analysing the case of Austria, where approximately one-third of rural areas have experienced such negative population change over the past decades, this paper will examine the impact on economic performance, income levels and well-being patterns. Addressing the crucial and persistent obstacles to positive population trends, new theoretical approaches and perspectives are discussed for overcoming limitations in development. Future approaches for regional development have to go beyond strategies for targeting economic growth, but have to address issues of local participation, social innovation and establishing trust as preconditions to effectively impact well-being dimensions. Such a mobilization effort would be the result of a comprehensive social transition process which would foster an altered narrative for these rural regions compared to the current and predominant focus on compensation and growth policies. Despite strong interlinkages with other regions and actors, the needs of local people would be central and both would be a cornerstone for social innovation.  相似文献

It has been noted that innovation seems to take place to a higher degree in clusters than elsewhere and we have lately seen a worldwide wave of emerging cluster initiatives and similar innovation policy projects. Some of these are realistic efforts based on existing regional strengths and partly existing cluster structures. Most, however, are grasping at straws. The latter is especially true when it comes to technologies such as IT and biotech. We could subsequently add a new label—“pathetic clusters”—to the already existing list of embryonic, emerging, world-class or stagnating clusters. But what do we make of such “pathetic clusters” (are they really pathetic)? Although economic geographers often tend to explain innovation (competitiveness) by looking at cluster dynamics, in such accounts, the cluster concept itself can actually function as an innovation, imposing similar effects on the economy as more familiar types of innovation would, i.e. by creating a local competitive edge. It is reasonable to believe that if “pathetic clusters” play important roles in regional economies, then they do so in the form of social and organizational innovations rather than as Porterian drivers of innovation and industrial dynamics on a large scale. This function of the cluster concept—as a local innovation—is the focus of the paper at hand.  相似文献

社会资本对区域经济增长的影响是通过对区内企业、产业集群及区域整体等三个不同主体的影响发挥作用的。在企业由传统成长模式向网络化成长模式转变,产业集群由聚集经济向创新网络转变,区域由空闻结构向网络社会转变的过程中,社会网络及内含资源起着决定性作用。社会资本对三者的作用体现空间上的层次递进特征,即依循企业、集群、区域三个不同主体网络化递进发展的“织网模型”,依次由“发散状企业网络”向“经纬状集群网络”再向“多构面区域网络”发展的织网过程。社会资本及社会网络对企业的作用是摄取关键资源、信息等;对产业集群的影响是建立学习与创新机制、成本节约机制、形成合作竞争氛围;而对区域的积极意义是保持区域良好的信任文化。  相似文献

In this paper, based on the case study of the aerospace cluster of the Basque Country (Spain), we aimed at analysing how local industries develop a new specialization, that is, how a cluster emerges, and how it evolves over time. For that purpose, apart from considering local factors (both forces that are internal to the cluster and to the territory), we explicitly consider the role of institutional and technological changes, and how they affect industry structure and governance patterns of global value chains (GVCs). We observe that global-scale regulations (deregulation and competition policy) and technological change, together with local factors such as the existence of anchor firms, local policies, related variety and social capital at regional and cluster levels played a significant role in the emergence of the cluster and how it became inserted in the GVCs. Later on, the development of suppliers' capabilities also had a relevant role in the evolution of the governance patterns of GVCs.  相似文献

This article aims at assessing the role of related variety, that is, the relatedness of knowledge bases used by different sectors within a region, as a major driver of clusters’ development. Some recent theoretical papers underline the role of clusters as ‘knowledge platforms’ organizing the recombination of technologies in overlapping industries, following the seminal definition of clusters by Porter as ‘geographic concentrations of linked industries’. In order to investigate the role of related variety in cluster dynamics, we analyse the patterns of development of clusters specializing in photonics in Europe. Photonics constitutes a new and rapidly evolving set of technologies with a high expected degree of technological recombination. However, due to inadequate traditional sectoral classifications, we propose an original method to delineate the perimeter of photonics in patent databases. A two-step algorithm is then used to identify systematically photonic clusters in Western Europe at the local level. In the last part of the paper, a typology of technological trajectories of clusters over the last decades is developed and then correlated with a set of quantitative measures of technological relatedness. The results highly confirm the role of related variety as a major driver of success, particularly for the biggest European clusters.  相似文献

This paper begins with the proposition that an analysis of the potentialities of industrial networks has to consider the wider context of the social organization of production. Recent work on industrial clustering has shown that successful clusters are embedded in tight networks of social relations between suppliers, producers, customers and institutions. Localized capabilities, such as specialized resources and skills, conventions and other local institutional structures, provide the basis for inter-firm cooperation. Based on Malmberg and Maskell's (2001) conceptualization of localized industrial clusters, I discuss the horizontal, vertical and institutional cluster dimensions as a basis for empirical analysis. In addition, attention will be drawn to the external dimension and power relations of a cluster which have a strong impact on its growth trajectory. This conceptualization is used as a basis for studying the new Leipzig media industry cluster. Leipzig, which is located in the Neue Länder (States of the former German Democratic Republic), has traditionally been a major centre of industrial production in Germany. After the German unification, a significant proportion of Leipzig's manufacturing activities were terminated or downsized. Interestingly, a new media cluster has developed during the 1990s, driven by the activities of the MDR (Middle German Television and Broadcasting Service). This has stimulated substantial start-up activities in branches of the media industry, such as film/TV production, new electronic services/interactive media, graphics/design, PR/marketing and media-related hardware/software. Being virtually the only sector which has grown in recent years, the media sector has stabilized the local economy. In this paper, I investigate those forces which have supported start-up and location decisions of media firms and the role of local institutions and policy programmes in the clustering process.  相似文献

This article analyses the history of Italian industrial districts (IDs) to identify lessons to help small and medium‐sized enterprise (SME) clusters in developing countries to move to higher stages of development. Transforming the 1990 seminal work of Brusco on distinct models of SME clustering into a stage approach, this article identifies a sequence of different maturity stages which the IDs passed through: initial craft production; industrialization through large firms; the fragmentation of production followed by the growth of smaller specialized units; and, finally, new routes to innovation and competitiveness. These phases help explain how development is a stage process which needs to be carefully considered and not rushed, through attempting to cross too many stages at once. Realistic steps are always necessary to create an effective base for growth. Furthermore, a theoretical framework is presented, which identifies three factorial levels that have intervened in the ID development process over the past 50 years. Economic, policy and social factors are identified and presented as drivers that work together to produce the structural changes that explain an effective development process. The final section emphasizes the relevance that this kind of analysis can have on the policy‐making schemes being applied in developing countries, with special reference to less developed types of clusters.  相似文献

ABSTRACT

The paper aims to contribute to better understanding of entrepreneurial discovery processes and regional industrial growth by examining (1) how different regional contexts affect entrepreneurial discoveries, and (2) how entrepreneurial discoveries support specific types of industrial path development in different regions. The paper includes empirical studies of the formation and growth of three ‘official’ regional clusters supported by Innovation Norway’s programme for immature clusters. The paper argues that entrepreneurial discoveries should be institutionalized (by system level entrepreneurs) to achieve considerable regional industrial effects. In our cases institutionalization occurs through the creation of cluster organizations and development of the knowledge infrastructure.  相似文献

The capabilities for visualization, rapid data retrieval, and manipulation in geographic information systems (GIS) have created the need for new techniques of exploratory data analysis that focus on the “spatial” aspects of the data. The identification of local patterns of spatial association is an important concern in this respect. In this paper, I outline a new general class of local indicators of spatial association (LISA) and show how they allow for the decomposition of global indicators, such as Moran's I, into the contribution of each observation. The LISA statistics serve two purposes. On one hand, they may be interpreted as indicators of local pockets of nonstationarity, or hot spots, similar to the Gi and G*i statistics of Getis and Ord (1992). On the other hand, they may be used to assess the influence of individual locations on the magnitude of the global statistic and to identify “outliers,” as in Anselin's Moran scatterplot (1993a). An initial evaluation of the properties of a LISA statistic is carried out for the local Moran, which is applied in a study of the spatial pattern of conflict for African countries and in a number of Monte Carlo simulations.  相似文献

本文认为有必要将中国城市新区开发运动理解为新区空间快速开发与城市空间不平衡发展的相统一过程。本文引入国家空间选择性理论视角来理解中国城市新区开发的"双统一"过程。首先,将国家空间选择性理论具体化为三个分析维度——选择性的空间发展战略、选择性的国家权力和国有资源空间配置。进而以南京河西新城为例,从国家空间选择性角度实证解析了其发展的"双统一"过程。主要结论是:国家的空间选择性给河西新城的开发配置了明显优于其他地区的战略、权力和国有资源条件,引导社会资本的集中涌入,塑造了不平衡发展的城市格局。国家空间选择性主导的发展模式一定程度上引致了河西新城发展的房地产化。  相似文献

Australia's metropolitan cities have undergone significant social, economic and demographic change over the past several decades. In terms of socio‐economic advantage and disadvantage these changes, which are often associated with globalisation, wider economic and technological restructuring, the changing demographics of the population and shifts in public policy are not evenly dispersed across cities, but represent a range of often contrasting outcomes. The current paper develops a typology of socio‐economic advantage and disadvantage for locations across Australian metropolitan cities. More specifically, the paper takes a range of Australian Bureau of Statistics data and uses a model‐based approach with clustering of data represented by a parameterised Gaussian mixture model and discriminant analysis utilised to consider the differences between the clusters. These clusters form the basis of a typology representing the range of socio‐economic and demographic outcomes at the local community level.  相似文献
