From 'industrial districts' to 'knowledge clusters': a model of knowledge dissemination and competitive advantage in industrial agglomerations 总被引:6,自引:0,他引:6
Pinch Steven; Henry Nick; Jenkins Mark; Tallman Stephen 《Journal of Economic Geography》2003,3(4):373-388
This paper integrates knowledge-based theories of the firm withgeograph-ical studies of industrial agglomeration to producea model that helps explain the competitive advantages enjoyedby proximate firms located in geographical clusters. We proposea hierarchy of specialized knowledge stocks at both firm andcluster levels and suggest that the comparative advantage conferredby knowledge resources at each level is protected, in part,by asymmetries in knowledge flows from level to level. The paperargues that codified component knowledge is more easily spreadthan firm-specific architectural knowledge. Nevertheless, overtime, agglomerations may develop a cluster-specific form ofarchitectural knowledge that facilitates the rapid disseminationof knowledge throughout the cluster by increasing the learningcapacity of proximate firms and thereby conferring cluster-specificcompetitive advantages. 相似文献

Evaluating the geographic concentration of industries using distance-based methods 总被引:13,自引:0,他引:13
We propose new methods for evaluating the spatial distributionof firms. To assess whether firms are concentrated or dispersed,economists have tradi-tionally used indices that analyse theheterogeneity of a spatial structure at a single geographiclevel. We introduce distance-based methods, Besag's L function(derived from Ripley's K function) and Diggle and Chetwynd'sD function to describe simultaneously spatial distribution atdifferent geographical scales. Our empirical applications considerthe distribution of French manufacturing firms in the Parisarea and in France generally. For some geographic levels, resultsshow significant concentration or dispersion of firms accordingto their sector of activity. 相似文献

Was the crisis of historicism an exclusively German affair? Or was it a “narrowly academic crisis,” as is sometimes assumed? Answering both questions in the negative, this paper argues that crises of historicism affected not merely intellectual elites, but even working‐class people, not only in Germany, but also in the Netherlands. With an elaborated case study, the article shows that Dutch “neo‐Calvinist” Protestants from the 1930s onward experienced their own crisis of historicism. For a variety of reasons, this religious subgroup came to experience a collapse of its “historicist” worldview. Following recent German scholarship, the paper argues that this historicism was not a matter of Rankean historical methods, but of “historical identifications,” or modes of identity formation in which historical narratives played crucial roles. Based on this Dutch case study, then, the article develops two arguments. In a quantitative mode, it argues that more and different people suffered from the crisis of historicism than is usually assumed. In addition, it offers a qualitative argument: that the crisis was located especially among groups that derived their identity from “historical identifications.” Those who suffered most from the crisis of historicism were those who understood themselves as embedded in narratives that connected past, present, and future in such a way as to offer identity in historical terms. 相似文献

Abstract: This article mobilises a strategic‐relational approach to state spatial restructuring to overcome the weaknesses of the conventional “New Regionalist” account in economic geography of the resurgence of the region as a strategic site for economic governance. Focusing on hegemonic projects and the shifting nexus of spatial dependencies and engagements through which these are reproduced, undermined and transformed, the role and geography of political agency in state spatial restructuring is highlighted. To illustrate this point, I analyse the construction of new regional state spaces in Belgium, paying particular attention to the hegemonic projects that create a social basis for particular state spaces, the construction of collective agency on different scales (Belgian‐national and Flemish‐regional) and the various ways in which these processes are informed by pre‐existing state spatial and scalar selectivities. 相似文献

The article seeks to explain the connection between the migration of the Magyars and Pechenegs in central and south-east Europe, in the late ninth and early tenth century, and the conflict between Byzantium and Bulgaria during the same period. Through reference to anthropologists discussing the relations between nomadic and sedentary societies (Khazanov, Barfield), and historians studying medieval rituals (Buc, Althoff, Koziol), the article interprets the aggressive policy of the Bulgarian tsar Symeon as a consistent effort to displace Byzantium as major partner of the nomadic polities in the area. By subverting the principles of Byzantine diplomacy and political culture, Symeon turned his own kingdom into a society-structuring factor in the nomadic world. The article evaluates the very meaning of imperial claims not so much in legal terms, as an effort to guarantee Bulgaria’s sovereignty in a Byzantium-centred world, but in the real-time capacity of a ruler to make use of imperial symbols and act upon the dynamically changing conjuncture. 相似文献

Research on past human diets in the southern Lake Titicaca Basin has directed us to investigate the carbon and nitrogen stable isotopes of an important dietary element, fish. By completing a range of analyses on modern and archaeological fish remains, we contribute to two related issues regarding the application of stable isotope analysis of archaeological fish remains and in turn their place within human diet. The first issue is the potential carbon and nitrogen isotope values of prehistoric fish (and how these would impact human dietary isotopic data), and the second is the observed changes in the fish isotopes through time. Out of this work we provide quantitative isotope relationships between fish tissues with and without lipid extraction, and a qualitative analysis of the isotopic relationships between fish tissues, allowing archaeologists to understand these relationships and how these values can be applied in future research. We test a mathematical lipid normalization equation to examine whether future researchers will need to perform lipid extraction procedures for Lake Titicaca fish. We also analyze a number of aquatic plants to better understand the range of isotopic signatures of the Lake Titicaca ecosystem. We use these data to better understand prehistoric human diet and the role that fish may have played in the past as well as potential changes in local lake ecology through time. 相似文献

Scientists from the National Institute of Standards and Technology (NIST) worked in a collaborative partnership with archaeologists from the National Park Service's (NPS) Submerged Resources Center (SRC) to develop a finite element model (FEM) of the battleship USS Arizona. An FEM is a computer-based engineering model that calculates theoretical stresses, propagation of force, and shape changes to a structure under loads using thousands or even millions of individual elements whose individual responses are well understood. NIST researchers created an FEM of an 80 ft. (25 m) midships section of the Arizona site to analyze archaeological site formation processes on the sunken battleship, in particular to determine the current condition of the wreck and predict its future strength and structural integrity as it continues to corrode. The NIST's FEM study is one aspect of a larger project under the direction of the NPS, the USS Arizona Preservation Project, whose goal is to determine the nature and rate of corrosion affecting USS Arizona, and to model its long-term structural deterioration. The FEM incorporates findings from other key components of the USS Arizona Preservation Project, such as steel hull corrosion rates, structural surveys of the vessel, sediment compaction studies, and analysis of the concretion that covers the ship's hull, into a single tool that is being used to predict how the wreck will degrade in the future. 相似文献

Esquilleu cave site has provided a moderately well preserved archaeological cave deposit from the Late Pleistocene in the Cantabrian area. Phytolith quantification, identification and determination of the refractive index have been carried out, together with FTIR analyses, from sediment samples collected in the profile. The comparison of the data obtained with the previous micromorphological results allows us to make inferences about the site formation processes and the Neanderthals use of the cave. Phytolith results show the presence of grass leaves nearby the hearth suggesting the repetitive existence of a bedding zone on the same area. Neanderthal behavioral patterns should be revised on the light of high resolution analyses, since diagenetic processes can obscure the existence of differentiated activity areas in the site. 相似文献

Burnt daga structures in Iron Age villages serve as proxies for severe drought on the plateau of southern Africa. The distribution of burnt daga remains in two other rainfall areas, KwaZulu-Natal and the Inter-Tropical Convergence Zone over Zimbabwe, Zambia and Malawi, establishes a sequence of simultaneous burnings that parallels the severe droughts recorded for the interior plateau. These widespread correspondences suggest a common cause. Another correspondence with natural proxy data from South America indicates that intensive El Niño events most likely caused the droughts. 相似文献
