Myopia, knowledge development and cluster evolution 总被引:9,自引:0,他引:9
This article aims to show how processes of knowledge developmentand their institutional underpinnings make up the core of evolutionaryeconomic geography. We argue that micro level concepts—notablyinnovation, selection and retention—provide insights thatcan be helpful also when investigating evolutionary processesof knowledge creation at the aggregate levels of cities, regionsor nations. We investigate the linkage between drivers, mechanismsand barriers to knowledge creation and acquisition at the micro-level,and the development over time and across spatial settings ofhigher-order phenomena of localized institutions and other capabilities.We apply this distinction on the analysis of the rise, growth,decline and possible rejuvenation of spatial clusters of similarand complementary economic activity. 相似文献

Innovations, Competitiveness and Local Embeddedness: A Study of Machinery Producers in Sweden 总被引:2,自引:0,他引:2
This paper is about technological relations and firm performance in the Swedish machinery industry. Taking its point of departure in the proliferating literature on the localized nature of learning and innovation processes, the paper sets out to answer three empirical questions: To what extent are firms integrated in localized production systems based on buyer-supplier relations? At what geographical level–local/regional, national or international–are the most important technological relations found? Is there a correlation between localized technological relations and the technological performance of firms? The results indicate that few firms display localized buyer-supplier relations. Rather, the industry is highly internationalized, with the most important customers and competitors located outside Sweden. In terms of technologically important relations, the domestic arena seems to be more important. The majority of the most important technological relations link the machinery producers to other actors in Sweden. Three out of four firms may be classified as predominantly local/regional or national in their technological relations, or technology profile. This survey therefore supports the notion that there exists both local/regional and national innovation systems. Finally, however, despite the fact that most firms are fairly locally embedded in their technology relations, there is no evidence that such embeddedness shows up as superior firm performance, in terms of technology level or innovative capacity. 相似文献

A wide range of industrial studies recognize the tendency of similar and related economic activities to co-locate in so-called industrial systems or clusters. While a cluster is defined by its cross-industrial relations the supporting and complementary role of cluster actors is seldom fully explored. This study will focus on the dynamics of cluster relations and give an account for the complementary nature of clusters by analysing anchor firms and complementary agents (such as specialized service providers and institutions for collaboration) in the Uppsala biotechnology cluster in Sweden. The empirical data used involves a triangulation of interview, survey and individual-based register data based upon a mapping of cluster actors active in 2002 and 2003. It is shown that both the formerly dominant pharmaceutical company and the local university have actively taken the role as anchor firms/organizations creating a local and dynamic milieu for biotechnology activities. Furthermore, it is shown that the local cluster consists of a variety of complementary agents contributing to knowledge spillovers and cluster competitiveness. 相似文献

The identification of sex in human remains recovered from archaeological locations is important in order to understand the social and biological structure of past societies, and to reconstruct past population demographic events. Sex determination is usually based on morphological traits of the skeletons, with the drawback that most methods do not apply to juveniles and require well preserved remains. In cases where morphological methods cannot be used, or are ambiguous, methods of molecular sexing systems are an alternative. In this methodological study we tested and validated the accuracy and usefulness of a molecular sexing method based on the amelogenin gene using pyrosequencing. We did this in a double blind study of documented 18th and 19th century human remains. 相似文献

AbstractToday many regions in the industrialized world have to deal with a transformation from traditional industry such as agriculture or manufacturing to service-oriented production such as tourism. Nevertheless, few studies highlight the possibilities and limitations of inter-sectoral knowledge sharing among stakeholders representing these sectors and hence there seem to be missed opportunities for mutual collaboration in the era of experience production. Using an evolutionary perspective, this article aims to analyse how the leisure boat manufacturing and the tourism sectors in the municipality of Orust on the Swedish west coast, combine knowledge from these two sectors as a way to spur innovation in experience production. The article shows how there are a number of limitations to sectoral knowledge interaction. Some of them can be linked to the conservative nature of the traditional industry, and to the immature nature of the tourism sector, others to the role of policy. However, at the same time as there being a number of obstacles for collaboration, the article reveals some interesting possibilities to form inter-sectoral knowledge sharing. 相似文献

For ceramics to be relevant in the Southern African Iron Age, archaeologists must broaden their theoretical base to include social and other contexts when interpreting material culture items such as pottery. Pottery remains critical in understanding cultural dynamics in the region for the past two millennia, but current usage is narrow in scope. Using ethnohistorical data and archaeological examples from South Africa and Zimbabwe, we argue that pottery provides valuable information on the region's Iron Age, if archaeologists address the social meaning of ceramic assemblages. Ceramic production among rural communities provides the basis on which a wide range of social issues are discussed and used to critique pottery recovered from archaeology. Ethnography suggests that ceramic assemblages are context specific, and archaeologists are cautioned against making generic statements on the basis of similarities of vessel shape and decoration motif. 相似文献

The doctoral dissertation is a key component of postgraduate education that plays an important role for knowledge production and hence the development of a discipline. Swedish human geography currently lacks an overview of dissertations. This article fills this knowledge gap by reporting findings from a unique database covering all doctoral dissertations between 1884 and 2015. The paper focuses on the demographics of the authors (age, gender), the format of the dissertation and explores productivity variations for authors of compilation dissertations. The findings show a notable increase in the number of doctoral dissertations since the late 1960s but a decreasing share of doctoral dissertations in the social sciences since the 1970s. In terms of demographics, we show that while the age of the authors remains relatively stable, the gender-balance has improved considerably. In terms of format, the monograph has rapidly given way to compilation dissertations, which now account for half the number of dissertations. More than 70% of all dissertations are now published in English. Statistical results suggest that the likelihood of completing a compilation dissertation is greater if the doctoral candidate is young and if attending Umeå University. But individual author productivity for compilation dissertations is mainly influenced by unobservables. 相似文献
