恰当的专利组合价值测度是国家衡量企业创新能力、制定合理产业技术政策的必要保障;是企业技术合作、交易等得以顺利进行的前置条件。本文以复杂专利组合价值测度为研究对象,从结构分析视角出发,在选取测度指标的基础上,首先利用综合比较与统计相关的方法判断同类专利内部指标组合方式;接着研究不同专利组之间的价值组合,运用结构方程竞争性比较来确定专利组合最佳分组;利用组指数套索回归找出关键变量组和关键变量,构造双层复杂专利组合价值评价模型。在以药品为例进行分析后,发现药品同类专利内部指标组合方式以几何平均为佳、组间则按照专利性质分组为优,并得到药品专利组合价值公式。进而将不同方法加以对比,分析本文方法合理性。本文创新之处在于以复杂双层专利组合为研究对象、使用结构方程竞争性分析获得专利组合最优分组形式、选择组指数套索回归以确定专利组合定价模型。模型符合专利组合价值评价的现实数据特点,同时将组合结构分析与组合价值评价相结合,能够有效捕捉专利组合的内在价值。本文丰富了专利组合价值评价的理论和方法,拓展了专利组合价值与评价维度的测度关系研究。 相似文献

重点探讨专利结构变动与我国企业经营绩效的关系。引入摩尔指数作为衡量专利结构变化的指标,进而通过建立向量自回归模型,分析1997—2014年间我国专利结构变动与企业综合绩效之间如何互相影响。研究结果显示:专利结构变动与企业经营绩效变化存在相互适应的关系,这种互适性在短期表现为专利结构变化对企业经营绩效的冲击,在长期则表现为企业经营绩效对专利结构变化的反向影响,同时企业经营绩效对专利结构的影响程度要低于专利结构变化对企业经营绩效变化的影响。这证明通过鼓励企业调整自身专利结构,有利于其绩效的提升。 相似文献

专利质量评价是政府或企业在投融资决策、技术产权转让、科研成果评价等过程中的核心问题,目前得到理论界与实务界越来越多的关注。本文通过对国内外现有的评价指标体系、评价模型以及专利质量含义等相关内容的调研与梳理,拟从技术、法律、经济三个视角出发构建专利质量评价指标体系;并针对现有评价方法的不足,提出运用直觉模糊层次分析法确定指标权重和利用模糊评价法对专利质量进行评估的综合评价模型。结合案例分析说明该模型可行性与有效性,为专利质量评价提供了一个更具科学性与实操性的新思路。 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

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

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

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
