社会资本对产学研合作知识转移绩效影响的实证研究 总被引：1，自引：0，他引：1
产学研合作是跨组织边界的创新活动,知识转移是产学研合作的重要环节.本文在已有研究的基础上,结合我国产学研合作实际,研究了产学研合作组织中社会资本的构成及其内涵,分析了社会资本各维度对知识转移绩效的影响;针对产学研合作跨组织边界的特点,引入界面管理作为中介变量,构建了产学研合作中社会资本、界面协调与知识转移绩效的结构方程概念模型并进行了实证.研究结果表明,社会资本的三个维度均对产学研合作知识转移绩效具有明显正向影响,界面协调具有显著的中介作用. 相似文献

网络嵌入性对产学研知识协同绩效的影响 《科学学研究》2017,35(9):1396-1408
产学研合作的网络化趋势影响着企业和学研机构之间的知识转移、共享与整合,探讨网络嵌入性对产学研知识协同绩效的影响机制具有重要意义。文章基于网络嵌入性视角,构建了网络嵌入性、知识搜索、产学研合作行为、产学研知识协同绩效之间关系的概念模型,提出了知识搜索与产学研合作行为作为中介变量的假设,并通过大规模问卷调查的数据进行了验证。结果发现：结构嵌入和关系嵌入对产学研知识协同绩效均有正向影响,知识搜索和产学研合作行为在“信任–产学研知识协同绩效”的关系中起完全中介作用,在网络嵌入性的其他三个维度与知识协同绩效之间的关系中都具有部分中介作用。论文的理论探讨和实证研究拓展了网络嵌入性的研究范围,深化了产学研知识协同的理论研究。 相似文献

创新网络技术多元化知识基础与企业创新绩效 《科学学研究》2022,40(9):1698-1709
在新一轮科技革命浪潮下,企业组建创新联合体成为大势所趋。合作创新网络中的多元化技术已经成为企业创新的关键外部资源,但关于创新网络技术多元化如何影响企业创新绩效的研究仍然缺乏,且现有研究往往忽略企业内外部资源的不同组合对企业创新绩效可能产生的差异性影响。文章融合社会网络理论、知识基础理论与动态能力理论,依据信息技术产业上市公司联合申请专利数据构建合作创新网络,采用面板数据随机效应负二项回归法,从个体网络视角分析创新网络技术多元化影响企业创新绩效的权变因素与内在机制,检验了一个被中介的调节效应模型。研究结果表明：创新网络技术多元化正向影响企业创新绩效;企业知识基础深度正向调节创新网络技术多元化与企业创新绩效的关系,而企业知识基础宽度的调节效应并不显著;企业知识基础深度对创新网络技术多元化与企业创新绩效关系的调节通过吸收能力的中介实现。研究结论对企业技术创新具有重要的理论及现实指导意义。 相似文献

在文献整理与归纳的基础上,提出产学研合作与创新绩效之间关系的假设模型。通过国内外主要文献数据库的查找,以及离群值和偏倚性检验,最终获得39篇相互独立的样本文献。经Meta分析方法处理后,研究得到了以下结论,产学研合作对创新绩效存在显著的正向关联;产学研合作对创新绩效的影响随时间因素和文化差异的变化而变化;当产学研合作为多维结构以及研究模型为结构模型时,产学研合作对创新绩效的作用更显著;中介变量的存在情况未能显著调节两者之间的相关关系。 相似文献

明清时代是我国古代科举制度发展的鼎盛时期,科举制度是当时人才选拔的首要途径,对士人知识视野影响有一定积极作用,表现为：统一了不同民族的知识认知,促进民族地区融合;选拔出大批优秀知识分子,为早期的社会发展做出巨大贡献;士人学习儒家知识转变为对程朱理学的思想信仰。更为主要是对士人知识视野的消极影响,表现为：使士人思想僵化,知识视野受限;扼杀士人的创新能力;排斥科学技术知识。 相似文献

A research 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 in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
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

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

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
