人才聚集是经济发展的核心问题,本文以1995-2014年高技术产业省级年度数据为样本,结合柯布-道格拉斯生产函数和Hansen提出的门限检验方法,以人均GDP为门槛变量,运用双重门槛模型,对科技型人才聚集度和协同创新产出的非线性关系进行实证分析。研究表明,较高的经济发展水平对协同创新产出的贡献率最大,但并非高技术人才聚集规模越高,对经济的促进作用越明显,它们之间存在一定的非线性关系,并以此提出了相应的政策建议。 相似文献

区域协同创新网络本质上是聚集地人才聚集所形成的复杂关系的集合。通过系统分析人才聚集效应与区域协同创新网络的内在联系,提出了基于人才聚集效应的区域协同创新网络关系模型。以山西省为例,运用社会网络分析方法,构建了基于人才聚集效应的区域协同创新网络。在此基础上,进行了整体网络与分类网络分析。结果表明:基于人才聚集效应的区域协同创新整体网络中,政府、高校和企业主体的网络密度均高于整体网络密度,科研院所网络密度较低,弱化了整体网络创新主体间的联系;研究型与应用型协同创新网络中的创新主体间大致呈现对立式和包围式分布,人才聚集的凝聚力均明显不足。上述研究结果,可进一步完善区域协同创新网络理论体系,并为相关政策制定提供参考。 相似文献

基础研究是区域技术创新和经济增长的重要源泉,而科技基础设施是科研活动的重要保障。运用2003—2016年我国30个省区相关数据,基于经典生产函数形式,实证分析高校基础研究投入、科技基础设施对区域创新绩效的影响效应,得出结论如下:从全国范围看,高校基础研究和科技知识基础设施对区域专利产出具有显著正向促进作用,科技物力基础设施则产生显著负向影响效应,高校基础研究和科技基础设施的协同作用对区域专利产出产生影响效应确实存在。从各地区看,基础研究、科技基础设施对不同地区专利产出的影响效应存在差异;基础研究和科技物力基础设施对各地区专利产出均产生显著正向协同影响效应,且东、中部优于西部。基础研究和科技知识基础设施对各地区具有正向协同影响效应,西部影响系数最高。 相似文献

政策测量、政策协同与技术绩效:基于中国创新政策的实证研究(1978-2006) 总被引：4，自引：0，他引：4
以创新政策为例,在政策量化方面进行了研究.通过量化政策,测量了政策之间的协同问题,并最终利用扩展的柯布一道格拉斯生产函数研究了政策协同与技术绩效之间的关系.给出了具体的政策量化标准操作手册,并利用计量模型得出了一些新的结论:第一,政策力度能够促进技术绩效的增长,而政策部门之间的协同对技术绩效的影响具有显著差异;第二,引进外资与创新协同能够在很大程度上促进专利授予数量的提高.对重大发明创造没有显著影响,却在一定程度上削弱了新产品产出比率;第三,人事措施与行政措施的协同对重大发明创造与新产品产出比率具有显著的正面影响,而对专利授予具有显著的负面影响. 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
