单纯从人力资本存量的角度,研究FDI在东道国的经济增长效应,不足以完全揭示东道国人力资本对FDI技术外溢效应的影响。文章利用中国东部、中部和西部地区所包含各省份的面板数据,从人力资本分布结构和内部结构的角度,较为系统的分析了人力资本结构对FDI技术外溢效应和区域经济增长的影响。实证检验结果表明,FDI对区域的经济增长效应,具有鲜明的人力资本结构特征。人力资本结构较为合理,将有助于区域从FDI中获益。  相似文献

本文以2004-2005年面板数据,从FDI企业角度全面实证中国汽车产业FDI的溢出效应,结果表明,FDI企业的确对中国汽车产业产生正的溢出效应,当然进入中国汽车产业的FDI也不是理想的,其具有挤出效应的一面.同时,FDI企业的溢出效应与技术缺口有较大的关系,FDI企业对技术缺口较大的改装制造业的溢出效应不显著,对技术缺口适中的整车制造业有正的技术溢出效应,而对技术缺口最小的零件制造业的技术产生挤出效应.本文认为"市场换技术"是中国汽车产业发展中的一个历史的且不可少的过程.  相似文献

本文构建测算模型,估计了基于货物贸易、FDI和服务贸易渠道从OECD成员国有效外溢到中国的环境技术知识存量,并建立1999—2013年中国30个省市的空间面板模型,实证分析并测度国际性环境技术知识的局域溢出效应和跨区域溢出效应.研究发现:从当期溢出效应来看,货物贸易、FDI外溢环境知识存量对中国整体环境技术进步发挥了重要作用,而服务贸易外溢渠道在局域内和跨区域间表现出强烈的溢出反差且总体上具有不确定性;从滞后溢出效应来看,估计结果与当期溢出效应结果类似,但滞后跨区域溢出效应显著度有所降低;从不同环境技术领域下的空间溢出效应分解结果来看,气候变化减缓技术与“三废”治理技术领域的估计结果存在一定差异,尤其是外资渠道对中国“三废”减排技术进步没有产生直接或间接的影响.  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

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

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

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
