以国家统计局发布的1978—2008年统计数据为基础,对中国政府科技投入与经济增长之间的关系进行计量分析,结果表明:中国政府科技投入与经济增长之间存在着单向的因果关系,政府科技投入是引起经济增长的重要原因;1978—2008年间,政府科技投入对中国经济增长的贡献率约为20.48%,表明政府科技投入一定程度促进了中国经济的增长,但作用还不是很大。要加强政府科技投入在经济增长中的促进作用,不仅要关注增加政府科技投入的总量,还要重视优化政府科技投入的结构和提高政府科技资源的使用效率。 相似文献

文章以国家统计局发布的1953—2002年度统计数据为基础,实证分析了中国经济增长与科技投入之间的关系。结果表明：(1)中国经济增长与科技投入之间存在着十分明显的因果关系,科技投入是引起经济增长的重要原因;(2)在1953—2002年期间,科技投入对我国经济增长贡献率约为17．6％,表明科技投入在一定程度上促进了我国经济增长,但其促进作用并不是十分明显;(3)要加强科技投入在经济增长中的促进作用,不仅要关注增加科技投入的总量,更要重视优化科技投入的结构和提高科技资源的使用效率。 相似文献

国家提出“实施创新驱动发展战略”以及“创新发展”居首位的五大发展理念,科技创新投入是创新驱动发展的前提和基础。本文采用省级面板数据,运用静态和动态面板数据模型探讨经济增长目标设置如何影响科技创新投入。研究发现：经济增长目标设置对科技创新投入并非单向线性影响,而是呈U形曲线关系。经济增长目标设置对5类科技创新投入的影响存在差异,主要表现为U形曲线拐点所对应的目标水平。这揭示了经济增长目标设置在科技创新领域的非预设结果,弥补了以往研究忽视目标设置对不同类型科技创新投入异质性效果的局限。 相似文献

采用2009-2015年中国31个省（市、区）的面板数据,从经济贡献率的视角对我国企业R&D活动的主体地位进行了再检验,并基于动态门槛面板数据模型分析了企业及政府两大R&D投入主体对区域经济的非线性差异性影响。研究认为,以R&D投入的经济绩效为评价标准,我国企业主体地位尚未真正建立;处于不同科技水平的地区,不同R&D主体的经济绩效存在差异：科技发展水平低于第一门槛时,政府R&D投入更利于促进区域经济;科技发展水平超过第一门槛时,企业才能显著促进区域经济发展;而科技水平超过第二门槛时,政府和企业对区域经济的带动效应趋于一致。我国现有研发活动中,政府和企业超过70%的R&D投入份额位于第二门槛之上,因此引导企业向中等科技发展水平地区的R&D投入,同时增大政府对科技落后地区R&D活动的扶持和补贴应成为我国科技政策的重要目标。 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

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
