《粤港澳大湾区发展规划纲要》中指出,粤港澳大湾区要"建设富有活力和国际竞争力的一流湾区和世界级城市群,打造高质量发展的典范"。文章对粤港澳大湾区与3个世界级湾区的产业发展进行了比较分析,发现粤港澳大湾区具备世界一流湾区的总量规模和条件,但是经济增长质量不高;区域化和工业化特征明显,高端服务业具有巨大的发展空间;香港、澳门与珠三角9市间的产业分割格局严重,合作潜力大,而珠三角9市间产业同构现象需要进一步统筹协调解决。未来需要进一步推动区域协同发展,通过扩大开放提升湾区的国际竞争力和影响力。 相似文献

通过社会网络分析方法,选取城市群中粤港澳大湾区城市群中20所高校作为考察对象,以中国知网数据库为检索平台,分析各高校间科研合作创新水平,了解其科研合作创新的基本情况。研究发现,粤港澳大湾区20所高校间科研合作频次较低,港澳高校普遍存在合作动力不足的现状,且港澳高校参与度更低,广东省内高校之间的合作占据主导地位;其合作频次依赖于相关政策和学科优势;合作模式主要通过研究项目与学术交流,科研合作创新模式呈现出强强联手、跨地合作的新模式。此外,为推动粤港澳大湾区城市群高校间科研合作创新和改善其合作空间结构,文章研究提出突破地域壁垒限制、开展多层次合作、统筹跨区域学科合作以及依托研究项目增进粤港澳大湾区合作创新趋向集群化发展等建议。 相似文献

建设粤港澳大湾区(以下简称"大湾区")国际科技创新中心,需要明确香港角色,并促使其更好地发挥作用。香港在4个方面具有独特优势:(1)高水平大学集群与自由的学术氛围,培育出大量创新人才;(2)基础研究优势,并在与大湾区其他城市的互动中促进技术创新;(3)一流的现代服务业,可为企业发展提供法律、金融等方面的支撑;(4)全球视野和良好国际形象,提升大湾区国际化水平。但同时,香港也在产业发展、创新政策实施和创业成本等方面有不少教训。善用"一国两制",加强两地互动,既有助于香港在已有的良好基础上探索形成新的、更加符合科技创新具体要求的优势领域,实现自身突破,也有利于贡献独特智慧,辐射大湾区建设,并推动我国科技体制改革,促进创新事业发展。 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

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

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
