How can clusters sustain performance? The role of network strength, network openness, and environmental uncertainty 总被引：2，自引：0，他引：2
This paper draws on social network theory to develop a model of regional cluster performance. We suggest that high performing regional clusters are underpinned by (1) network strength and (2) network openness, but that the effects of these on the performance of a cluster as a whole are moderated by environmental uncertainty. Specifically, the positive effects of network openness on cluster performance tend to increase as environmental uncertainty increases, while the positive effects of network strength on cluster performance tend to decrease as environmental uncertainty increases. Our findings have theoretical and practical implications for social network research in general, and cluster research in particular. 相似文献

To identify how a governance structure leads to ambidexterity at the cluster level, in terms of knowledge management, this study draws on the knowledge -based view of clusters and on ambidexterity literature, thereby exploring an ‘intermediated’ cluster model of ambidexterity. Our aim is to explore the governance structure’s role and priorities in terms of knowledge management, as well as the underlying operational actions and programmes implemented to achieve cluster ambidexterity. Qualitative research, based on interviews with members of two French clusters, reveals that their governance structure is a crucial intermediary organisation that supports cluster ambidexterity. The results emphasise the role of governance structures for two types of ambidexterity in small and medium-sized enterprise (SME) clusters: First, SMEs may specialise in exploitative or exploratory knowledge, and the governance structure provides the missing knowledge (intermediated specialised model). Second, cluster governance may help each firm become ambidextrous (intermediated dual model). This study outlines the specificities of the two models and their contingency factors, which offer interesting implications, especially for policymakers devoted to innovation and clusters. 相似文献

基于自组织和他组织理论分析航空经济区发展演变机理,认为航空经济区是在机场与航空产业集群、机场与周边地区其它产业和当地经济互动的自组织机制中形成发展,政府他组织通过制度创新和政策供给发挥他组织作用。在此基础上借助Logistic模型构建一个理论框架进一步分析后认为,自组织状态下航空经济区系统内各产业主体的合作协同和政府他组织的支持都会使系统处于高效的运行状态。据此提出要树立航空经济区自组织的发展观、重点支持具有地方特色的航空主导产业、引导航空经济区各产业主体之间的合作等政策建议。 相似文献

Clusters,convergence, and economic performance 总被引：1，自引：0，他引：1
This paper evaluates the role of regional cluster composition in regional industry performance. On the one hand, diminishing returns to specialization in a location can result in a convergence effect: the growth rate of an industry within a region may be declining in the level of economic activity of that industry. At the same time, positive spillovers across complementary economic activities can provide an impetus for agglomeration: the growth rate of an industry within a region may be increasing in the “strength” (i.e., relative presence) of related industries. Building on Porter (1998, 2003), we develop a systematic empirical framework to analyze the role of regional clusters – groups of closely related industries operating within a particular region – in the growth of regional industries. We exploit data from the US Cluster Mapping Project to examine the effects of agglomeration within regional clusters after controlling for convergence at the region-industry level. Our findings suggest that industries located in a strong cluster register higher employment and patenting growth. Regional industry growth also increases with the strength of related clusters in the region and with the strength of similar clusters in adjacent regions. We also find evidence of the complementarity between employment and innovation performance in regional clusters: both the initial employment and patenting strength of a cluster have a separate positive effect on the employment and patenting growth of the constituent industries. Finally, we find that new regional industries emerge where there is a strong cluster. These findings are consistent with multiple types of externalities arising in clusters, including knowledge, skills, and input–output linkages. 相似文献

产业集群形态演化阶段探讨 总被引：19，自引：0，他引：19
国内外学者对产业集群的研究大多基于产业集群显现阶段的特征、机制与绩效表现等方面,众多学者对产业集群形态界定的多样性正是产业集群持续演化不同阶段的"快照"。本文根据复杂系统演化的分析思路,提出了产业集群演化的阶段分析模型,揭示了产业集群演化的四个阶段形态,并指出集群政策的核心在于促使产业集群自组织向更高级的阶段形态进化。 相似文献

运用重复博弈理论分析区域产业集群企业间交易过程,发现当集群内有一个合作激励组织对企业间不合作的行为惩罚足够大,即大到永誓不与交易,就会威慑到那些有不合作或背叛动机的交易企业,形成合作均衡,从而使企业间走向合作。分析温州产业集群企业合作中自发组建的商会发现,该组织在市场交易中为交易企业提供一个合作框架,有效地监督了潜在交易企业的不诚实行为,激励所有企业间的交易从欺骗均衡转到合作均衡,实现了集群内的企业走向制度化合作。 相似文献

In this paper, we describe a model of information retrieval system that is based on a document re-ranking method using document clusters. In the first step, we retrieve documents based on the inverted-file method. Next, we analyze the retrieved documents using document clusters, and re-rank them. In this step, we use static clusters and dynamic cluster view. Consequently, we can produce clusters that are tailored to characteristics of the query. We focus on the merits of the inverted-file method and cluster analysis. In other words, we retrieve documents based on the inverted-file method and analyze all terms in document based on the cluster analysis. By these two steps, we can get the retrieved results which are made by the consideration of the context of all terms in a document as well as query terms. We will show that our method achieves significant improvements over the method based on similarity search ranking alone. 相似文献

摘要：已有关于集群成长机制的研究大多关注于集群的内部，本文将研究视角拓展到集群之间的关系，进而构建了一个基于集群要素禀赋与集群间关系的集群成长分析框架，并且通过对中国54个国家级高新技术开发区13年数据的经验分析，最终得出了一些有意义的结论：除了人力资本之外，集群的要素禀赋对集群的成长具有非常重要的促进作用；集群间关系对集群成长具有至关重要的影响，集群的密度、集群间的地理接近程度以及集群间的产业重叠度对集群成长都有显著的倒U效应。最后，根据研究结论为高新技术开发区的设立、区位选择、产业定位以及内部建设和管理提供了合理的政策建议。 相似文献

In this paper, a document summarization framework for storytelling is proposed to extract essential sentences from a document by exploiting the mutual effects between terms, sentences and clusters. There are three phrases in the framework: document modeling, sentence clustering and sentence ranking. The story document is modeled by a weighted graph with vertexes that represent sentences of the document. The sentences are clustered into different groups to find the latent topics in the story. To alleviate the influence of unrelated sentences in clustering, an embedding process is employed to optimize the document model. The sentences are then ranked according to the mutual effect between terms, sentence as well as clusters, and high-ranked sentences are selected to comprise the summarization of the document. The experimental results on the Document Understanding Conference (DUC) data sets demonstrate the effectiveness of the proposed method in document summarization. The results also show that the embedding process for sentence clustering render the system more robust with respect to different cluster numbers. 相似文献

Despite the vast literature on knowledge management, little research has addressed the specificities of knowledge integration at the cluster level. Moreover, the literature on clusters has not focused on the role that governance may play in knowledge management. Anchored in a knowledge-based perspective, this paper aims at bridging the two fields, filling the gap by analysing the role of cluster governance in knowledge management. An empirical study of two small French firm clusters was carried out based on 29 interviews. The data analysis consisted essentially in content analysis. The clusters studied were characterized by distinct knowledge management processes. In both cases, governance was necessary in order to support knowledge integration by member firms. Our results suggest that establishing an initial common knowledge base seems to be a prerequisite in order for the external knowledge identification and acquisition processes to take place. The activist role played by governance also seems more efficient than that of a broker. We discuss these results and their implications for policy-makers and cluster members. 相似文献
