政府引导型创业基金是政府推动一国创业投资和技术创新发展的重要措施,而通过专业金融机构的运作,又可以发挥财政资金的杠杆作用,因此,在政府引导型创业基金的设立过程中往往会选择合适的社会管理机构来开展基金的运营管理工作。针对政府引导型创业基金管理机构的选择问题进行研究,通过设计4个方面18项具体的评价指标,运用区间值多属性决策方法对银行、信托公司、担保机构、融资租赁公司等管理机构进行综合评价。区间值的运用不仅解决了定性指标赋值的不确定性困难,并且运用离差最大化的原理可以根据评价对象样本值的实际情况对指标权重进行动态调整,使该方法具有更好的适用性。 相似文献

知识产权质押融资风险由于存在很大的不确定性,因此在评价中可以运用区间数对各项指标进行赋值。区间数TOPSIS方法的应用在一定程度上解决了不确定性指标赋值的主观性问题,但也存在一定的缺陷。本文运用马氏距离对欧氏距离进行替换,克服了属性之间存在线性相关性时欧氏距离失效的缺陷,同时引入联系向量距离解决可能存在的距离正理想解近的方案可能距离负理想解也近的问题,从而综合马氏距离和联系向量距离较为全面的对TOPSIS方法进行改进,使该方法更具科学性和合理性,最后运用改进后的区间数TOPSIS方法对知识产权质押融资风险进行了评价,并对评价结果进行了比较分析。 相似文献

政府引导基金下创业投资经理人与风险企业的合谋分析 总被引：4，自引：0，他引：4
在风险企业家、创业基金经理人、投资者的三方动态博弈中,投资者是信息的弱势群体,是利益最易受到损失的一方,基金经理人可能选择与风险企业合谋损害投资者利益.尤其是对于政府引导基金参与的创业投资来说,基金经理人既可以作为投资者的代理人获得佣金收益,也可能通过与创业企业的合谋获取额外收益.本文分析了基金经理人选择合谋的利益基础,同时给出了降低合谋可能性的一些措施. 相似文献

小微企业是我国实体经济实现平稳快速发展的重要力量,其在国民经济中的地位尤为重要。由于小微企业具有起步晚,规模小,资金不足等特点,银行信贷已经成为其生产经营的主要资金来源。以商业银行小微企业信贷业务为研究对象,进行信贷业务操作风险评估研究。首先,通过评价方法分析,选择一种适用于多级指标评价指标体系的区间值模糊评价方法;构建了风险评估指标体系结构,确定了模糊评价模型的因素集、评语集、权重集;在此基础上,通过对评估模型的数据收集和整理,进行二级指标和一级指标评价矩阵模糊运算,完成风险管控体系分析;最后以内蒙古银行企业信贷业务操作为例,进行了风险评估,验证了本文所提方法的合理性和有效性。 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
