学术与政治之间存在着“卡普兰鸿沟”,它阻碍着知识向政策的转化,而知识中介的出现则使跨越“卡普兰鸿沟”成为可能。那么,何谓知识中介?它又是如何推动知识向政策转化的?论文首先深度挖掘了知识中介的起源、内涵和类型,然后从“结构洞”理论的视角出发,探讨了知识中介在联结研究与政策的认知网络中所发挥的知识管理功能、桥接功能、双向能力建设功能、寻求一致性功能以及知识导航功能等。然而,知识中介也面临着三个极具争议的问题,即脆弱性、双重边缘性和道德风险。从理论上澄清知识中介问题,对于打通中国学术研究通往公共政策的“最后一公里”有着重要的启示。 相似文献

长期以来,厂商与用户之间存在的成本鸿沟被认为难以跨越,然而,随着云制造等新制造模式的兴起,构建跨组织成本协同机制成为厂商与用户的合作主导关系面临的关键问题。从产品制造为核心的商业模式刚性、竞争为主导的企业边界、产权鸿沟下市场机制的局限、决策代理人利己选择等多维度,对传统制造环境下的厂商成本与用户成本鸿沟形成机理进行解析,提出以价值生态系统为内核、推进产品与服务一体化、构建动态契约合作机制以及"连接红利"的跨界成本协同平台为路径的厂商成本、用户成本协同模型,为云制造环境下跨组织的成本优化提供理论框架,并通过案例分析对理论框架进行验证。 相似文献

In search of useful theory of innovation 总被引：1，自引：0，他引：1
This essay presents an overview of the prevailing theoretical literature on innovation, probes the adequacy of existing theory to guide policy regarding innovation, and sketches some directions for more fruitful theorizing. The focus is on the vast interindustry differences in rates of productivity growth, and other manifestations of differential rates of technological progress across industries. It is argued that the most important policy issues involve finding ways to make the currently lagging sectors more progressive, if in fact that can be done. Theory, to be useful, therefore must organize knowledge and guide research regarding what lies behind the uneven performance of the different economic sectors. In fact prevailing theory cannot do this, for two basic reasons. One is that theory is fragmented, and knowledge and research fall into a number of disjoint intellectual traditions. The second is that the strongest of the research traditions that bear on the differential innovation puzzle, research by economists organized around trying to ‘fit’ production functions and explain how production functions ‘shift’, neglects two central aspects of the problem; that innovation involves uncertainty in an essential way, and that the institutional structure supporting innovation varies greatly from sector to sector. The bulk of the paper is concerned with sketching a theoretical structure that appears to bridge a number of presently separate subfields of study of innovation, and which treats uncertainty and institutional diversity centrally. 相似文献

The massively growing documents make it a challenge for researchers to find high value papers. To solve information explosion, some work on personalized paper recommendation have been proposed. However, the knowledge gap between a researcher's background knowledge and research target is seldom concerned. In this paper, we propose a new method of recommending helpful papers to support researchers by bridging the knowledge gap. First, domain knowledge is extracted as the concept map, which provides a basis of comparing user background knowledge and target knowledge. Then, the knowledge gap is defined with the concept map. To bridge the knowledge gap, the shortest concept paths are searched to explore some suitable knowledge paths, which can help researchers to acquire target knowledge in accordance with their cognition patterns. Finally, experiments are performed to demonstrate the effectiveness of the recommendation method. 相似文献

内部社会资本对技术创新的影响——知识创造的中介作用 总被引：4，自引：0，他引：4
以往对社会资本的研究更多关注于外部社会资本的作用,而忽略了对内部社会资本的重视.为弥补这个研究缺陷,以北京和广州的133家企业为调查对象,以内部社会资本为自变量,对内部社会资本是否以及如何通过知识创造影响技术创新进行了实证研究.结果表明,内部社会资本对技术创新具有显著的直接影响,知识创造在此过程中起着重要的中介作用. 相似文献

The digitalization phenomenon is leveraging new relationship models through the entire supply chain network. In this outlook, blockchain is a cutting-edge technology that is already transforming and remodeling the relationships between all members of logistics and supply chain systems. Yet, while studies on blockchain have gained a relative pace over the recent years, the literature on this topic does not report sufficient research cases on blockchain adoption behavior at the individual level. The present study, therefore, aims to bridge this gap, notably by helping understand the individual blockchain adoption behavior in the logistics and supply chain field in India and the USA. Drawing on the emerging literature on blockchain, supply chain and network theory, as well as on technology acceptance models (TAMs), we have developed a model based on a slightly-altered version of the classical unified theory of acceptance and use of technology (UTAUT). The model being developed was then estimated using the Partial least squares structural equation modeling (PLS-SEM). As the model was eventually supported, the results obtained revealed the existence of distinct adoption behaviors between India-based and USA-based professionals. In parallel, the findings appear as a useful contribution to and a sign of progress for the literature on IT adoption, SCM, and blockchain. 相似文献

A quantitative graphical method is presented that identifies a set of technologies within an agricultural production sector that best serves a number of socio-economic goals. Technical research objectives that are derived from this set of technologies can be used by agricultural R&D policy planners as a guide when deciding on the selection and encouragement of specific research programmes.The application of this approach is illustrated with an example from sheep husbandry and wheat cultivation in a semi-arid zone in Israel. It is shown that the set of socio-economically viable technologies includes some of those that are applicable today as well as those that require more research. Despite the fact that some technologies do not meet all the goal criteria, they are currently applied for various reasons.It is suggested that the approach developed here can serve to bridge a communication gap between the agricultural development administration and the research establishment when evaluating agricultural R&D policy. It can also be used to determine the socio-economic limits to technological development in a given situation. 相似文献
