技术能力积累途径的螺旋运动过程研究 总被引：21，自引：0，他引：21
本文首先从技术能力演化的轨迹和技术能力积累的机制出发,研究内部途径和外源途径在技术能力演化中的互补作用。然后提出了技术能力形成的内外途径交替的螺旋运动模式,即在技术能力演化的每个阶段中,技术能力积累途径都经历了从外部技术源到内部学习的转换过程,这样就构成了技术知识外源与内部技术学习的三次循环。最后研究杭州制氧机厂在半个世纪中技术能力积累途径的演变过程。 相似文献

技术能力是企业竞争优势的重要来源,是企业在持续的技术学习中选择、获取、消化吸收、改进和创造技术并使之与其他资源相整合,从而产生产品和服务的累积性知识。技术能力的演化受制于企业的技术学习,而技术学习的有效性又是由企业的隐性知识吸收能力决定的,因此,本文构建了一个基于隐性知识吸收的企业技术能力演化模型。 相似文献

新兴技术知识网络跨界融合的机理与实证研究 《科学学研究》2021,39(5):854-866
新兴技术跨界创新推动了知识网络的跨界融合演变。基于德温特专利数据库,以虚拟现实技术为研究对象,运用社会网络分析法,通过构建专利引文网络,研究新兴技术知识网络跨界融合的知识流动路径演化和网络态势。结果表明：新兴技术知识流动路径按照“单向路径-混向路径-双向路径”模式演化,核心企业和外围企业的不断增加拓宽了双向路径的发展空间;知识流动路径数量的激增和方向的分散导致企业和地区知识网络跨界融合的涌现,呈现出异质性知识增加、知识连接灵活、网络规模扩大的跨界融合特征;中心企业与中心地区通过“中心地区自引、非中心地区引中心地区”的知识流动偏好进一步强化跨界融合能力,体现出明显的先发优势。 相似文献

企业动态能力的形成和演化——基于知识管理视角 总被引：6，自引：0，他引：6
在研究能力的知识属性、动态能力知识构成的基础上,综合应用知识管理的“内容观”和“过程观”思想,提出了动态能力演化的知识活动概念模型,对企业动态能力形成和演化的知识活动及其内在机理进行分析。分析认为,各种类型的知识活动是企业动态能力形成的基础和来源,动态能力的演化依赖于企业的知识管理活动,组织学习机制是动态能力持续发展的根本保障。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
