Diffusion of R&D within the Australian Wine Industry     

《普罗米修斯》2012,30(4):351-366

The Australian wine industry's popular image as a leader in R&D can indeed be substantiated. Its oenological and viticultural innovation and technical expertise have set new international benchmarks. The coordination of this R&D has ensured that the industry remains at the leading edge. However, the findings of this paper also substantiate concerns that this R&D is concentrated in what appears to be a South Australian R&D 'epicentre'. Regions and wine operators not connected to this epicentre can be disadvantaged. This paper examines the diffusion of R&D to regional operators and suggests mechanisms for improvement of the current structure.  相似文献

Technology transfer revisited from the perspective of the knowledge-based economy   总被引：2，自引：0，他引：2  

Fernand Amesse  P. Cohendet   《Research Policy》2001,30(9)

This contribution proposes a revised framework for understanding and analyzing the process of technology transfer in the perspective of the knowledge-based economy (KBE). The underlying hypothesis is that the context of the knowledge-based economy introduces a major shift in the way technology transfer is conceived. The traditional model of technology transfer was based on the vision of technology moving from one well-defined economic unit to another well-defined unit. We suggest that in the new perspective technology transfer is essentially considered as a specific knowledge-transfer process that depends on the ways firms and other institutions manage knowledge, in particular the co-evolution of their absorptive capabilities and their knowledge-transmission strategies. To support the theoretical analysis, we analyze the business case of Nortel Networks over the past 50 years.  相似文献   

The diffusion of ideas in the academy: A quantitative illustration from economics     

Shaun P. Hargreaves Heap  Ashok Parikh 《Research Policy》2005,34(10):883-1632

It has long been recognised in policy discussion that the influence of new ideas depends not just on their generation but also on the way in which they diffuse through society. However, while the spread of new ideas in industry has been much studied, there are no similar quantitative studies on diffusion within the academy. This paper addresses that gap by providing quantitative evidence on the adoption of two techniques for empirically testing hypotheses in economics. On the basis of this evidence, and contrary to a common expectation, the spread of ideas seems neither straightforward nor especially rapid in the academy.  相似文献   

技术创新扩散中企业采用行为的一种解说   总被引：2，自引：0，他引：2  

陈欣荣  蔡希贤 《科研管理》1996,17(2):17-21

企业采用创新的过程是技术创新扩散中的基本过程,它具有多方面的特征,对此学术界已有几种不同的解说,如曼斯菲尔德的“传染”说,戴维、戴维斯的“刺激——反应“说,斯通曼的“学习”说,梅特卡夫、阿瑟的“选择”说,等等.它们无疑都具有合理的成份,但往往只强调了企业采用行为的一个侧面、一种特征.本文提出一种可以把几个方面的特征综合在一起的新的解说.j  相似文献   

基于P（x）-Laplace流的向量值图像恢复模型     

董刚 《人天科学研究》2010,(2):168-170

提出一种基于变指数型扩散方程的向量值图像（例如RGB图像或多谱图像）恢复模型。在新的模型中,我们利用光滑后向量值图像的几何流形特征来判断图像的真假边缘,利用P（x）-Laplace型扩散系数来控制扩散量和扩散方向。由于扩散系数具有良好的自适应判断边缘能力,新的模型在图像恢复的同时良好地保持了图像边缘。通过数值实验,对比以往的全变差模型,所提模型具有更好的图像恢复效果,明显减少了＂块状＂效应。  相似文献   

产学研协同创新系统的技术扩散与资源配置关系研究——基于内资与在华外资高技术企业的比较     

李苗  刘启雷 《科技管理研究》2018,(23)

产学研协同创新系统的技术扩散与其内部资源配置效率密切相关,且两者的关系在异质性协同网络中具有显著差异。搜集内资企业如华为、中兴通讯和比亚迪以及外资研发密集企业如艾默生网络能源、三星电子和辉瑞制药的资料。应用扎根理论比较分析两类异质性创新主体产学研协同创新中的技术汇聚和扩散模式;进而构建了多种群状态下产学研协同创新系统技术扩散与资源配置的关系模型,揭示了技术扩散影响资源配置的机理及差异性。  相似文献   

中国房地产市场区域发展不平衡的实证研究     

张婷婷 《北京工业职业技术学院学报》2008,7(2):118-122

一国房地产市场的发展与其经济发展密不可分,中国作为经济大国,区域经济周期的不平衡性决定了区域房地产市场发展周期的不平衡。利用上海和黑龙江两地房地产市场的资料,采用扩散指数和多元线性回归法对两地房地产市场发展周期不平衡的现象进行定量分析,说明我国房地产市场的发展存在着比较显著的区域周期发展不一致的状况,从而得出我国目前实行的以经济发达地区的房地产市场发展情况为主要依据的统一房地产调控政策的不可取性,提出应以各地市场发展的真实情况为基础,制定符合各地区发展阶段的区域性房地产调控政策。  相似文献   

The small group subtlety of using ICT for participatory governance: A South African experience     

Hossana Twinomurinzi  Jackie Phahlamohlaka  Elaine Byrne 《Government Information Quarterly》2012

The greater number of government efforts to stimulate participative governance in communities using Information and Communication Technology (ICT) often fall short of expectations. In South Africa extending e-government to communities has been in the form of more and/or better equipped ICT-enabled community centres, called Thusong Service Centres. In this paper, based on action research experiences, we report outcomes of interpretive research into ICT-enabled approaches to participative governance in communities. Using the Diffusion of Innovations theory as an analytic lens, the findings reveal a subtlety that is not often mentioned in the call for participative e-governance; people from communities prefer to work in groups rather than individually. The collectiveness inclination is a common denominator of many developing countries where people choose to come together to leverage the few available resources. Individuals become apprehensive when made to work on their own using the ICT. The research reveals the necessity to re-design ICT to suit small groups as part of participative e-governance rather than the normative ICT design that suits individual work styles. Additionally, the research reveals that by working in groups, communities are more willing to accept the government initiatives that are being energised with the use of ICT. Methodologically, the research revealed the ethical issue that arises from action research in its raising of unrealistic expectations in a community.  相似文献
