促进新能源汽车产业供需双侧政策与政府采购、商业运营和私人乘用三类异质性市场之间的良性互动和合理配置,这是我国新能源汽车产业发展过程中亟待解决的现实难题。从政府采购、商业运营和私人乘用三类异质性市场比较的视角,利用面板数据回归和面板分位数回归分析了供需双侧政策对新能源汽车需求市场培育激励效应的差异性及其产生的原因。研究结果表明,三类异质性市场由于形成原因和目标消费群体的不同表现出不同的发展潜力,呈现交替发展的态势;供需双侧政策对于三类异质性市场的作用效果具有差异性,并且需求侧相比供给侧政策的作用效果更为显著。新能源汽车供需双侧政策的激励效果随着政府采购、商业运营和私人乘用三类异质性市场规模变化而呈现出差异性。新能源汽车产业政策制定时应充分考虑政策实施效果的市场异质性性和规模差异性,有针对地实施差异化的扶持政策。 相似文献

近年来,中国先后推出了“扶持性”和“门槛性”两种类型的新能源汽车产业政策。本文基于中国新能源汽车上市公司数据,使用双重差分模型,检验了“扶持性”政策和“门槛性”政策对企业技术创新的影响及其机制。研究结果发现：(1)“扶持性”和“门槛性”政策都激励了企业技术创新;就单个政策而言,“门槛性”政策比“扶持性”政策的创新激励效应更大;但两种政策的创新激励存在互补效应,其政策协同比单一政策对企业技术创新激励效应更大。系列稳健性检验之后我们的结论依然成立。(2)机制检验表明,“扶持性”政策通过加大研发强度等资源补偿效应激励企业创新;而“门槛性”政策的创新激励效应与市场竞争的程度密切相关,只有适度的市场竞争才会激励企业技术创新。(3)两类政策对创新激励的影响存在企业和地区方面的异质性。本文拓展了新能源汽车产业政策(类型)影响企业创新的相关研究,为新能源汽车产业政策优化以持续促进汽车产业高质量发展提供了经验参考。 相似文献

本文选取2015-2018年新能源汽车产业110家上市公司面板数据,探索政府补助与市场融资及其协同配合对企业研发创新影响的差异性。结果显示,新能源汽车产业政府补助对企业研发创新具有显著激励效应,市场融资并未显著促进企业研发创新,政府补助与市场融资协同配合能有效促进新能源汽车产业研发创新。通过进一步研究发现,处于不同新能源汽车产业链阶段的企业,政府补助对中上游企业研发创新的激励效应更大,而市场融资对下游企业研发创新的激励效应更大,政府补助与市场融资协同配合对中上游企业研发创新的激励效应更大。同时,相对于国有企业,新能源汽车产业政府补助与市场融资及其两者协同配合对非国有企业研发创新的激励效应更大。本文在一定程度上丰富了创新激励与政府干预理论,并为政府扶持新能源汽车产业精准设计创新政策提供理论指导。 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

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

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

The main premise of this article is that in information societies generally, and in virtual social contexts particularly, a distinctive style of interaction to facilitate the communication of difference, heterotopic communication , has emerged. It rests on two cultural foundations: an ideological belief in the positive, socially integrating power of communication, and a prevailing ethic of instrumental rationality, subjective individualism, and strategically practiced self-interest. The former is demonstrated by the use of simulation and spectacle as sources of information; exhibitionism/voyeurism as a communicative style; and the awareness of surveillance. The latter is seen in the competitive use of knowledge as a commodity; a surface globalism masking deep parochialism; lateral as well as vertical information inequity; and the use of public versus private as strategies for engagement rather than as spaces. Those who engage in heterotopic communication resort to their 'own devices' both in the sense of personal agendas, strategies, interests, and interpretations, and in the form of the telecommunication tools that help realize them. These personal and technological devices allow individuals with the right educational and technical resources to avoid exposure to disagreement, difference, or other information that does not serve their direct purposes or reflect their particular views of the world; yet they also help convey the appearance of openness, availability, and cooperation. This style of interaction is used strategically in combination with information and communication technologies to gain social or economic advantages, but it may encourage social separatism and parochialism, inhibit the negotiation of disputes, and emphasize competing interests. 相似文献
