为解决农村水利供给不足、供给效率不高等问题,需要改进农村水利供给模式。分别对政府供给、市场参与农村水利供给、协会及第三部门供给优势与效率损失进行分析。接着,采用向量自回归(VAR)方法,实证量化不同供给主体下的协同效应水平,得出国家财政投入与有效灌溉面积之间存在Granger因果关系,企业私人投资、银行贷款、农户自筹投资能够增加有效灌溉面积,但不能有效构成有效灌溉面积增加的Granger因果关系。因此,需要建立以政府投入为主导、政府与市场相结合农村水利供给体系。 相似文献

浅议我国风险投资市场需求导向型制度供给模式的建立 总被引：3，自引：0，他引：3
首先介绍了新制度经济学中的制度供需和制度短缺的理论,并用该理论对我国风险投资市场的现状进行了分析,指出政府是我国风险投资市场制度供给的主体,政府的制度供给应该以制度需求为依据,并为风险投资市场主体即民间资本服务,从而使风险投资的参与者直接受益于制度供给。着重分析了我国风险投资市场的多方面制度需求,并针对这些制度需求提出了相应的对策建议,得出了我国政府应逐步建立风险投资市场需求导向型的制度供给模式的结论。 相似文献

农村公共产品是具有非竞争性和非排他性,用于满足农村公共需要的产品。公共产品从理论上分析应该由政府提供,但由于混合产品的存在也为其他主体参与农村公共产品的供给提供了理论支持。现阶段,我国农村公共产品供给不容乐观,存在供给总量不足、供给主体失衡等问题。本文结合我国农业产业化发展的趋势,提出通过引入多元化主体、推动城镇化建设、健全农村金融市场、深化税费改革等措施构建农村公共产品有效供给机制。 相似文献

通过对高新技术商业化过程中的横向维度分析研究,归纳出一般意义上的商业化模式,并将商业化模式的实践分为供给导向和需求导向两种类型的应用路径,其中供给导向型路径是由政府主导的技术的商业化过程,而需求导向型路径则是由产业主导的商业化技术的过程。通过比较两种实践路径阐述商业化模式的具体内涵。 相似文献

土地资源配置体制与供给模式对房地产市场影响的路径分析 总被引：2，自引：0，他引：2
土地资源配置体制与供给模式对房地产市场影响日益凸显。本文系统回顾我国城市土地资源配置的演进过程,对土地储备实施制度前后供给模式及其特点进行对比分析,归纳土地供给模式对于房地产市场影响的路径。土地供给模式从宏观和微观层面对房地产市场产生系统性的影响,地方政府是重要的利益相关者。稳定市场预期,增加供给渠道,规范土地收益使用机制是稳定房地产市场的必要举措。 相似文献

风险投资发展过程中存在市场失灵,因此需要政府的干预.政府的制度供给应当建立在市场参与者的真实需求之上,但我国出于对发展高技术产业的迫切需求,在风险投资发展过程中出现了强制性的制度供给,并形成了政府通过直接参与主导风险投资的现象,改变这种现象的关键在于改变制度供给的基本模式. 相似文献

农业信息化服务的准公共品属性决定了政府在其体系建设中的主导作用,但现实中往往存在"政府失灵"现象。为解决这一问题,文章通过分析现存农业信息化服务供给主体特征,提出了一种符合我国国情的"政府+市场"的农业信息化服务的混合供给模式,使不同地区、不同经济状况的信息化服务需求者在该模式中均能从中找到适合自己所需要的农业信息化服务方式。 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
