本文构建了高技术制造业和科技服务业的复合协同系统,在文献梳理的基础上,阐述了该系统的创新机制并建立了评价指标体系,基于2009-2016年的相关数据,采用复合系统协同度模型对两产业的创新协同度进行测度,同时测算高技术制造业内部各子行业与科技服务业的创新协同度。结果表明,当前高技术制造业创新子系统和科技服务业创新子系统的有序度处于"初步协调"阶段,但受到创新环境子系统的影响,整体协同度处于"较差协调"阶段;各子行业中,除了电子计算机及办公设备制造业与科技服务业的创新协同度非常低且发展并不稳定外,其他子行业与科技服务业的创新协同度能够呈现出逐年上升的趋势。根据研究结果,提出促进两产业复合协同系统创新发展的相关建议。 相似文献

文中通过对科技创新与金融协同理论机制的分析,构建科技创新、金融有序度模型与复合系统协同度模型,并利用浙江省1990—2013年年度时间序列数据对浙江省科技创新与金融体系协同效应进行实证测度与分析。结果表明:浙江省科技创新子系统、公共金融子系统以及市场金融子系统的有序度均呈现出明显的上升趋势;科技创新与公共金融体系、科技创新与市场金融体系之间的协同度在样本期内整体呈上升趋势,由于科技创新子系统的内在不稳定性,协同度在不同年份间存在一定波动;科技创新子系统与市场金融子系统协同度高于科技创新子系统与公共金融子系统协同度,且二者的差距伴随时间推移存在扩大趋势。在此基础上,提出提高浙江省科技创新与金融协同效应的针对性建议。 相似文献

粤港澳大湾区科技创新协同机制研究 总被引：1，自引：0，他引：1
利用粤港澳大湾区2001-2019年间的科技创新数据,通过建立复合系统协同度模型来测度科技创新协同度,并在此基础上研究粤港澳大湾区科技创新协同机制.研究发现,第一,粤港澳大湾区城市间、区域间、部门间的科技创新协同度较低但发展趋势呈上升态势,各子系统有序度的差异性是导致协同度较低的重要因素;第二,在新经济地理的3D框架下,经济密度、交通便利、通信设施、市场化、对外开放和政府干预等的发展都对科技创新协同度产生积极影响,但人口密度的增加没有提高其协同度,这些经济地理要素构成协同机制系统,同时呈现空间个体异质性;第三,在拓展分析中,社会网络分析方法表明,粤港澳大湾区个体间具有自主技术创新临近特征.在当前国内外复杂的环境下,系统又全面地研究湾区科技创新协同发展具有重要的现实意义,结论将给粤港澳探索推进协同创新为科技湾区建设加添动力提供参考. 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
