旅游产业集群的网络构成分为核心网络与外围支持网络。旅游产业集群网络由主体、旅游资源以及旅游活动三部分组成。论文把旅游产业集群网络结构分为原子式、单核式、多核式、混合式等4种形态。论文把旅游产业集群网络结构空间相互作用分为三个层次:第一层次是核心旅游企业之间及相关旅游企业之间的竞争与合作;二是旅游企业和研究机构、地方政府、旅游中介机构及旅游投资机构之间的空间作用;三是旅游产业集群内部主体,主要是旅游企业与旅游产业集群外部成员之间的交流与互动,并以杭州国际旅游综合体为例对这三个层次的空间相互作用进行了分析。  相似文献

以国际物流企业为研究对象,考察国际物流企业在中国的进入路径与空间网络构筑规律。首先,划分了国际物流企业进入中国的发展阶段,分析了其结构特征和进入扩张模式,探讨了国际物流企业进入与中国物流政策与市场门槛的关系;然后,重点考察了国际物流企业的中国网络结构,包括网络单元类型分异与功能分异,深入分析了其区位选择,重点包括企业总部和网络单元的区位选择法则与空间规律。最后,以敦豪速递为案例,分析了20世纪80年代以来在中国的网络拓展过程与区位选择的规律。本文有助于进一步考察外资在中国的网络建设与市场拓展规律。  相似文献

北洋军阀统治时期,军人干政成为北京政治生活中的常态。内阁作为北京政府的最高行政机构,不仅掌握着中央财力的分配权和地方督军、巡阅使的任命权,且作为正统的合法性来源,成为军阀竞相角逐的对象。内阁阁员群体的社会结构和社会网络表明,地域因素、同学关系、亲属关系等都是影响内阁群体构成的重要因素。这表明中国在封建王朝向近代国家转变的过程中,传统社会关系对现实政治具有深刻影响。  相似文献

This paper examines and reflects on the activities of the International Network for Learning and Teaching Geography in Higher Education (INLT) from its founding at the Association of American Geographers' Annual Conference in Hawaii in 1999 to the post-International Geographical Congress workshop in Glasgow five years later. It provides a context and introduction to the following six papers, which resulted from the Glasgow workshop. It is suggested that, despite some of the proposals in Hawaii proving over-ambitious, several other projects have emerged and the INLT continues largely to meet the goals and purposes set out in 1999. Although the desire of the INLT to move beyond its Anglo-American and Australasian origins largely remains a challenge to be met, the INLT has established itself as a valuable forum for the geography higher education community to identify and reflect on similarities and differences in national practices, to engage in debate virtually and face-to-face on issues concerned with learning and teaching, and to bring geographers from different countries to work together on educational projects.  相似文献

Abstract: This paper interrogates the multiple spatialities bound up with the consumption of units as the dominant means of diagnosing “health‐related” alcohol problems and measuring “drunkenness” in international alcohol policy and research. In order to question the power afforded to units, we work at the intersection of theoretical debates concerning biopower and governmentality; emotional, embodied and affective geographies and actor network theory. Presenting empirical research from the UK we contribute to geographical agendas that seek to consider the ontological and epistemological understandings of alcohol, drinking and drunkenness. The paper concludes by calling for dialogue between social, health and medical scientists in order to develop more pertinent ways of understanding and representing the risks and benefits of alcohol consumption.  相似文献

The idea that governance has replaced government, and that networks have replaced hierarchy as the dominant mode of governance, have become mainstream views in the public policy literature. In this article, we consider a key initiative of the Rudd government in Australia, the 2020 Summit, which, at first sight, seems like an example of network governance in action. Having considered the operation and outcomes of the Summit, however, we argue that it more accurately illustrates how governments, perhaps particularly in Westminster systems, attempt to preserve hierarchy, through a process of metagovernance.  相似文献

A variety of data indicate that the Carbonate aquifer in southern Manitoba is a heterogeneous and anisotropic aquifer wherein groundwater flow follows preferred flow path networks. Specific capacity tests show that aquifer transmissivity can vary by up to four orders of magnitude within 1 km. Geostatistical analysis reveals a strong anisotropy in the transmissivity field, with better spatial continuity in NE–SW and NW–SE directions, coincident with the dominant orientations of fractures observed in bedrock exposures. However, discrepancies between the orientation of highest fracture density and best transmissivity continuity suggest that either additional geological factors control the preferred flow network or there is a biased representation of the fracture pattern because all direct fracture observations came from the northern part of the study area. In an effort to investigate whether the geographically biased fracture data set represents the fracture pattern for the whole region, Landsat images and digital elevation maps were processed to extract linear features that may indicate subsurface fracture zones in areas where bedrock is covered by glacial sediments. The results suggest a consistent fracture pattern throughout the study area, indicating that the two observed fracture groups might have gone through different processes in terms of permeability development. Alteration by mineral cementation and dissolution along fracture surfaces may have preferentially improved the fracture permeability in one orientation, while reducing it in the other. The in situ stress field is also believed to play a major role in the preferred regional flow network. This paper discusses the evidence for the preferred flow path network and possible geological factors controlling aquifer anisotropy in this region.  相似文献

This article analyzes the mechanisms through which metropolitan governance is established in Montreal's aeronautics sector, one of the most important and innovative industries in the region. The article also examines the role of lead firms, socio‐economic actors, and public agencies from a territorial point of view. It is established that on the one hand the existence of a small number of prime producers at the local level facilitates productive linkages among businesses through subcontracting, and on the other hand, the intensive participation of intermediate socio‐economic agencies and organizations ensures a metropolitan anchoring of the sector and creates a strong territorial identity among the players.  相似文献

中世纪英格兰运输役起源于庄园领主的物资供应需求,随着12、13世纪市场的激增以及运输条件的改善,市场型运输役逐渐普及。运输役一般由农民上层承担,其运输距离、目的地、运输种类等都受习俗制约。运输役衰落的原因主要有直营领地的衰落、运输的专职化以及私下交易的流行。运输役的兴衰与中世纪英格兰市场培育密切相关,是市场已有一定发育但还不太成熟的产物。  相似文献

The purpose of this paper is to spatially and regionally examine academic engagement within Brazil, identifying patterns. Moreover, our investigation can contribute to a better understanding of how knowledge can be turned into a tool to fight regional inequality. We depart from two hypotheses: first, universities situated in peripheral regions interact more with companies from relatively more dynamic regions, and second, in the absence of industrial knowledge demand, universities tend to collaborate more closely with a diverse range of stakeholders in the region. To evaluate these hypotheses and find empirical evidence, we consider 4497 research groups and 4603 nonacademic organizations as “nodes” connected by 8830 collaborations throughout all Brazilian regions. Social network tools are used to illustrate the spatial and regional dimensions of academic engagement more accurately. The results show that academic engagement is not regionally homogeneous, demonstrating essential differences regarding local nonacademic partnerships. Innovation policies, which encourage only university–firm interactions, perpetuate regional inequality.  相似文献
