可再生能源技术创新在应对气候变化和推动能源转型中发挥着关键作用,党的十九大报告明确提出构建市场导向的绿色技术创新体系。与政府环境政策相比,市场力量是否能更有效地促进可再生能源技术创新?本文以可再生能源技术世界领先、政府环境政策实施较早以及能源市场自由化程度较高的欧盟为研究对象,结合线性与非线性、静态与动态面板回归方法研究政府政策和市场竞争对欧盟可再生能源技术创新影响。研究发现：①政府环境政策和市场竞争对可再生能源技术创新的影响均为正向,即两者能有效诱发可再生能源技术创新。②政府环境政策和市场竞争对可再生能源技术创新的正向影响存在显著的非线性门槛效应。随着政府环境政策强度加大,其对可再生能源技术创新的正向影响逐渐递减,即环境政策对创新的诱发作用是有限的。随着能源市场竞争程度加深,市场竞争对可再生能源技术创新的正向影响增加,即市场竞争对创新的诱发作用是有效且持续的。③通过将各成员国现状与门槛值进行比较,发现欧盟现阶段环境政策强度处于过高的门槛区间,市场竞争强度处于较为合适的门槛区间。④进一步研究更有针对性的可再生能源政策,发现不同政策对可再生能源技术创新的影响存在异质性。研究结果可为中国实现能源转型、深化电力体制改革以及建立全国可再生能源绿色证书交易机制提供政策依据。 相似文献

可再生能源技术创新是促进能源转型和经济高质量发展的重要一环。已有研究多从国内经济因素探讨环境政策对可再生能源技术创新的影响,较少从制度层面以及开放的国际视域开展研究。本文利用1998—2016年32个国家的面板数据,运用多元回归分析方法,首先引入政策强度计量政策严格性,探索国内外环境政策对本国可再生能源技术创新的动态影响,其次选用制度质量作为制度环境优劣的度量指标,探讨制度因素对环境政策效果的调节作用。研究发现：①国内外环境政策对本国可再生能源技术创新均存在正向影响,但这种影响存在一定的时间滞后期;②国外环境政策对本国可再生能源技术创新的影响早于国内环境政策,国外环境政策的“政策溢出”效应存在;③制度质量正向调节国内环境政策对本国可再生能源技术创新的影响,制度质量的提高能够增强环境政策的创新激励效应。研究结论可为中国进一步优化环境政策体系、推动可再生能源发展提供科学依据。 相似文献

开展影响电力结构的能源技术的识别与评价,对于深化电力改革,发展新能源具有重要意义。本文从电力产业链角度出发,界定了46项可能对电力行业发展产生影响的能源技术,通过层级分析法建立指标评价体系和确定权重,以技术领域专家调查问卷为基础,采用模糊综合评价法对能源技术在不同时间节点对电力结构的影响程度进行分析。结果显示,近期对我国电力结构高影响度的技术主要是集中式发电技术,到2030年后,影响程度高的能源技术转向分布式能源技术,且以可再生能源为主。在此基础上,对电力集团应重点关注的储能、氢能、分布式能源及能源互联网技术领域给出了布局建议。 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

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

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
