在企业技术创新能力测度方面的研究一直采取指标分析方法,但现有的测度缺乏具体的量化,对创新能力大小的测度难以用具体的量化强度进行表达,对创新能力各指标间的关系缺乏有机的匹配分析。本文从研究开发、生产制造、市场营销三个维度构建了测度企业技术创新能力的三维模型(RPM三维模型),提出并界定了创新能力强度概念,建立了各维度能力强度测度的计算方法,并对各维度能力强度的匹配进行了综合测度,建立了创新能力协同效应的测度方法。并用此模型和测度方法,对深圳市数字电视企业的技术创新能力进行了实证分析。 相似文献

摘要：IT如何给企业带来竞争优势，促进企业绩效提高一直是众多学者关心的问题。本文探讨了在环境压力的作用下，IT能力、知识管理战略和组织绩效三者之间的关系，并构建了理论模型。本次研究以我国东部、中部、西部的397家企业为样本，对模型进行了实证检验。研究结果发现，IT能力能够通过中介变量知识管理战略对组织绩效产生正向影响。企业采用知识管理战略能够促进绩效的提高。环境压力虽然对组织绩效的直接影响为负，但也可通过IT能力和知识管理战略间接正向影响组织绩效。 相似文献

企业家导向、战略柔性与自主创新关系研究 总被引：1，自引：1，他引：1
在提出能力柔性概念的基础上，将战略柔性分为资源柔性和能力柔性。并通过战略导向与战略柔性的结合，提出了一个分析企业家导向、战略柔性与自主创新关系的概念模型。分析结果表明，企业家导向主要通过能力柔性促进企业自主创新，而尽管企业家导向能够提升企业资源柔性，但过分强调资源柔性却会阻碍企业自主创新。 相似文献

企业战略柔性关键影响因素实证研究 总被引：2，自引：0，他引：2
企业战略作为决定企业的整体性、长远性发展目标的基本政策和程序方针,应具有相对的稳定性,然而,随着电子商务的变革,企业开始面临高度动态和形态多样的竞争环境,致使作为事关全局的企业战略同时还应具有调整变革的灵活性,然而,稳定性与灵活性之间存在的矛盾使许多企业倍感困惑,而企业战略柔性恰好能够在战略的稳定性和灵活性之间找到最佳平衡点,并成为解决这一矛盾最有效的途径.本文从理论上分析了反映企业战略柔性程度的四大主要测度指标,即能力柔性、组织柔性、文化柔性以及资源柔性,基于此提出企业战略柔性关键影响因素理论模型,并进行了实证研究,实证结果显示理论模型得到数据支持. 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
