基于知识转移过程理论和技术联盟过程中所呈现的特征和相关影响因素,提出了技术联盟知识转移影响因素概念模型。通过实际采集的数据对技术联盟过程中影响知识转移效果的因素进行实证分析,采用简效适配测量与绝对适配测量相结合的分析方法对模型数据进行整体适配度检验。研究结果表明：知识转移实施过程显著影响知识转移效果;对于潜在变量知识转移实施过程来说,知识转移投入、知识转移方式和知识转移情境适应性对其有显著的正向影响作用;联盟双方的信息对称性对组织知识识别能力有正向显著作用,组织的知识识别能力对知识转移实施过程的直接影响不显著,但通过正向显著影响知识转移方式而对知识转移过程有间接的促进作用;知识源的知识转移能力和知识接收方的知识吸收能力对知识转移情境适应性有正向的积极影响。最后本文根据以上研究结果提出了技术联盟知识转移效果的影响路径以及促进技术联盟知识转移效果的对策建议。 相似文献

供应链企业间信任、关系承诺与合作绩效——基于知识交易视角的实证研究 总被引：1，自引：0，他引：1
以供应链企业间知识交易为视角,构建了信任、关系承诺、知识交易与合作绩效之间关系的理论模型。利用结构方程模型结合256家供应链上下游企业的调查数据对上述理论模型进行了实证研究。研究结果表明,供应链企业间信任对关系承诺、知识交易与合作绩效有显著的正向影响;关系承诺对合作绩效有显著的正向影响,但其对知识交易的影响并不显著;知识交易对合作绩效有显著的正向影响。研究结果告诉企业管理者,不仅要重视供应链企业间高水平信任与关系承诺的建立,而且要通过加强知识交易以促进供应链企业间的知识共享与转移,从而实现供应链合作绩效的提高。 相似文献

业从外部转移和引进知识是快速获取创新能力和竞争优势的有效途径,也是综合成本最低的途径。本文利用结构方程对企业文化、知识整合机制与企业间知识转移绩效的关系进行了实证研究,并选取我国环渤海地区的 155家高新科技企业作为实证研究对象。研究结果表明：（1）企业创新型文化不但对企业间知识转移绩效有显著的正向直接影响,而且还分别通过人员交流以及团队交流两个知识整合机制分别对企业间知识转移绩效产生显著的正向间接影响。（2）支持型文化对企业间知识转移绩效没有直接的显著影响,但通过程序交流,仍然对企业间知识转移绩效产生显著的正向影响;（3）知识整合机制包括人员交流、团队交流和程序交流,均对企业间知识转移绩效产生显著的正向直接影响。 相似文献

为探明企业组织层面上技术联盟知识转移有效性的差异来源,梳理现有相关文献并探索性的提出组织间学习、战略柔性与技术联盟知识转移有效性关系的研究假设,以山西、天津等华北地区联盟企业的308份有效调研问卷为样本,采用基于最大似然估计法的结构方程建模进行实证分析。研究结果表明,组织间学习可以显著地提升不同类型的战略柔性(资源柔性与能力柔性);能力柔性正向作用于技术联盟知识转移有效性,而资源柔性却相反;组织间学习在受到资源柔性负向传导效应的干扰下仍然可以正向促进技术联盟知识转移有效性;组织间学习、不同类型的战略柔性对技术联盟知识转移有效性的影响确实存在显著差异。本研究在推进相关理论研究的同时,也为联盟企业合作实践提供可操作的指导依据。 相似文献

本文通过建立中介模型,实证分析了联盟企业间关系公平性对关系承诺的影响,并探讨了企业间信任的中介作用。论文以江苏230家企业为研究样本,通过量表收集数据,并使用层级回归分析的方法来检验所提出的假设。研究结果表明,我国企业间合作关系中存在着关系公平性对关系承诺的影响路径。其中,分配公平性直接促进企业间情感承诺水平的提升,同时通过才能信任对情感承诺产生间接影响;程序公平性主要通过才能信任这一中介变量对情感承诺实施正向影响;互动公平性可以降低企业间的计算承诺水平,同时还有助于提升企业间的仁善信任水平,间接对计算承诺产生影响。本文最后提出了相应的管理建议。 相似文献

摘要：在激烈的市场竞争下,许多企业通过与其他企业或科研机构构建技术联盟来规避技术研发风险并迅速扩大组织的整体知识存量和技术水平,以提升企业竞争力。知识转移是技术联盟主体组织学习和取得外部知识的重要途径。本研究基于过程的视角,探索和验证了组织在构建和实施技术联盟过程中各个影响因素如何影响技术联盟知识转移效果。本文作者通过深入哈尔滨汽轮机厂的研发部门和生产一线,以参观和访谈的调研方式取得了哈尔滨汽轮机厂与美国GE公司的9FA联合循环机组D10汽轮机技术联盟的第一手资料。本文通过哈汽轮机厂与GE公司的技术联盟案例实证验证了知识转移过程各影响因素如何影响技术联盟组织间知识转移效果。实证验证结果表明：技术联盟中知识源的知识转移能力和知识接收方的知识吸收能力作为外因潜在变量通过积极影响内因潜在变量知识转移情境适应性和知识转移过程对知识转移效果有显著的正向促进作用;联盟主体间信息对称性作为外因潜在变量对知识转移效果的正向积极影响是通过影响内因潜在变量的中介机制形成的,该影响路径中内因潜在变量分别为组织知识识别能力、知识转移方式和知识转移过程;知识转移投入通过正向影响知识转移过程进而促进知识转移效果。本研究的创新之处在于：在理论和实证研究的基础上,通过对实际案例的剖析验证了技术联盟组织间知识转移影响因素对知识转移效果的作用路径,便于企业研发人员和科研管理人员理解和应用本文的研究结论,增加了结论的可操作性和实际应用价值。 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 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

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 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
