Low agricultural productivity remains the primary source of poverty in the developing regions and yet little is known about the influence on agricultural productivity of domestic and international accumulated R&D knowledge and the channels through which this knowledge is transmitted internationally. Following a large scientific literature, this article argues that R&D and R&D knowledge spillover are ecozone‐specific and, therefore, are transmitted internationally through ecozones, where ecozones are the broadest biogeographic division of the earth's land surface. Using data for a panel of 88 countries, it is shown that international knowledge spillovers are ecozone‐specific and have been an important contributing factor behind the marked widening of the income gap between developed and developing countries since 1983.  相似文献

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM.  相似文献

知识交易的定价   总被引:7,自引:0,他引:7  
周波 《经济研究》2007,42(4):79-89
就知识经济理论而言,知识交易是不应该被忽略的关键性主题。根据知识供给者面对的市场不同,知识交易的定价分析方法也不同。定价模型揭示了效用不确定性、效用的动态性、信息不对称、非重复交易、交易方式的多样性等对最优定价以及社会福利的影响。知识交易理论是知识经济学的微观基础。  相似文献

创新柔性对企业在不确定性环境下保持健康稳定发展至关重要,如何提升企业创新柔性受到学界关注。现有文献侧重研究单个因素对创新柔性的净效应,鲜有分析多因素对创新柔性的协同效应。基于组态视角,运用模糊集定性比较分析法(fsQCA),探讨网络能力和知识共创两个层面的5个变量对企业创新柔性的联动效应及其作用路径。结果表明,网络愿景、网络构建、网络管理、联合型知识共创和嵌入型知识共创均不是构成企业高、非高创新柔性的必要条件,且单个前因条件对创新柔性的解释力较弱,说明影响企业创新柔性的因素是多方面的;存在3条提升企业创新柔性的路径,即资源获取型、发展—管理型和单一型;导致企业非高创新柔性的路径有两条,且与高创新柔性路径影响因素存在非对称性关系。研究不仅能丰富创新柔性相关理论,还可为企业提升创新柔性提供思路借鉴。  相似文献

Mobility at the destination is an important element of the tourism system on islands. Tourists have mobility needs that are often met by trains, buses, taxis and other means of transport there. The competitiveness of the taxi industry can be strategic for destinations because it is an industry with a traditional high proportion of entrepreneurs and SMEs. The knowledge-based view has contributed to understand firm performance better, and knowledge-based factors can be crucial for taxi competitiveness. The impact of taxi drivers' knowledgebased- aspects on tips are analysed, since this last factor is an interesting proxy for competitiveness due to its link to tourist satisfaction and potential loyalty. The empirical approach of this work is based on a survey in Gran Canaria, Spain. Knowledge of foreign languages (with mixed results), driving knowledge and knowledge creation seem to exert a significance influence on tips and play a relevant role in taxi competitiveness.  相似文献

Risk management has been a discipline for decades. However, organizations have only recently begun to introduce a separate enterprise risk management (ERM) function. The aim of this study is to examine the transformation of the ERM function's influence in a company over time. We use a historical case study informed by social theory on how to influence others to investigate this phenomenon. The findings show that the construction of risk technologies over time triggers a change in the ERM function's influence on decision-making. Two processes of influence are used by the ERM function: selling new ideas and managing knowledge across boundaries. In the first process, the ERM function attempts to vertically influence top management's decisions regarding acceptance of new risk management technologies. In the second process, the ERM function attempts to horizontally influence decision makers to use risk knowledge in decision processes. Theoretically, our findings contribute to our understanding of how the ERM function influences decision-making in organizations over time.  相似文献

仪器作为现代科学研究的核心组成部分,在很大程度上决定了科学知识的产出。虚拟仪器技术对知识创造产生了深远影响。“软件就是仪器”的理念使得传统仪器、测量观念以及仪器作为科技黑箱的内涵和功能发生了质的变化。虚拟仪器在集成大量编码知识的同时更多地集成了主体的隐性知识,虚拟仪器技术通过对主体知识体系的重塑影响了知识创造。主体只有通过长时间、复杂的学习和使用过程才能充分发挥虚拟仪器技术在知识创造中的优势,实现编码知识和隐性知识的共同增长。  相似文献

SUMMARY

Knowledge management is identified as a key success factor in most industries today. While data or information can be stored independently from people, knowledge is bound to people who use it for their interactions. The main goal of knowledge management is to improve the usage of knowledge in the enterprise. Knowledge management systems are not only organizational memory information systems. They also contain organizational standard procedures and a certain cultural attitude. A reference framework gives implementation hints mainly influenced by technical possibilities. The knowledge management system reference architecture contains layers of sources, repositories, taxonomy, services, applications and user interfaces. A software tool that largely corresponds to this reference framework is the Knowledge Café. Possible applications of this tool to the area of hospitality and tourism are described in this paper.  相似文献
