网络地理边界拓展与创新能力的关系研究——路径依赖的解释视角 总被引：1，自引：0，他引：1
网络边界拓展与创新能力之间存在复杂的内在关系,本文综合知识基础观和组织经济学理论,从路径依赖解释视角提出集群企业知识网络地理边界拓展与创新能力的理论框架和关系假设,并以来自浙江、江苏247家制造型集群企业为样本进行实证分析,研究表明:(1)知识网络地理边界拓展与创新能力之间并非单纯的线性关系,两者间存在倒U型关系;(2)集群企业自身整合能力增强网络地理边界拓展与创新能力间的曲线关系。 相似文献

探究基于探索式创新的知识整合能力对企业突破式创新的影响,并进一步从内外部机制角度解释企业吸收能力与创新开放度对主效应的调节作用。通过对2011—2019年中国计算机通信及电子设备制造业和医药制造业457家上市公司的数据分析发现,创造型知识整合能力对突破式创新的促进作用大于混合型知识整合能力;吸收能力与创新开放度均对混合型知识整合能力与突破式创新间的积极影响产生正向调节作用,但二者并未在创造型知识整合能力与突破式创新的关系中起到调节作用。研究发现为企业通过跨领域、跨行业技术融合提升的突破式创新提供思路,同时为企业从内部提升动态能力与从外部加强跨组织协作提出了相关建议。 相似文献

集群企业是集群创新的微观基础,而合理选择技术创新模式是提升集群创新能力的关键。本文通过构建演化博弈模型分析了集群企业技术创新模式选择的内在动态决策机理,并以绍兴市5个全国百强产业集群的201份调查问卷为基础进行了实证分析。研究发现:(1)集群企业技术创新模式的选择需要在企业规模、资金实力和技术积累的基础上正确考量自主性创新和合作性创新的成本和收益作出选择决策;(2)新产品更新率、与供应商或销售商的合作程度与集群企业创新能力显著正相关;(3)企业竞争程度、企业自主品牌和企业规模可以显著促进选择自主性创新的集群企业创新能力;(4)与高校及科研院所的技术合作、本地物流效率与选择合作性创新的集群企业创新能力存在显著的正向影响。 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

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

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
