为了促进我国燃煤电厂投资CCS(二氧化碳捕集与封存)项目,立足燃煤电厂的视角,以实物期权为基础,构造CCS项目投资激励模型。从投资不可逆性、收益不确定性及投资时机可选择性以剖析燃煤电厂CCS技术实物期权特性,并从碳税、清洁电价补贴和政府投资补贴该3个方面建立与临界碳价的关系,且比较了碳税、投资补贴、清洁电价补贴3种变量的激励效果。通过研究得知,在碳捕获和封存技术中,政府对发电商进行成本补贴最为有效,即便是补贴很低却也能大幅推动碳捕获和封存的投资。  相似文献

当今世界,碳减排已经成为一个新的行业与外交热点.碳交易制度也在全球各主要经济体中相继建立、发展.然而,作为一种旨在降低排放的制度设计,碳交易本身对工业排放无能为力.碳减排归根到底需要相应的技术作为支持. 碳捕集与碳封存(CCS)技术是目前公认的控制二氧化碳排放、应对气候变暖的重要手段,国际社会对此高度重视.国际能源署(IEA)《2009年CCS技术路线图》更提出到2050年全球投资2.5万亿~3万亿美元建成3400个CCS项目的设想.碳捕集与碳封存技术为企业在碳交易市场中增加了筹码.  相似文献

目前碳捕捉与封存(CCS)技术作为一种新的温室气体减排手段受到西方发达国家热捧,然而目前CCS还远未达到商业化推广阶段,其大规模实施还存在一定的不确定性。中国作为煤炭生产和消费大国,CO2减排形势相当严峻,对CCS进行深入研究就显得十分重要和迫切。由于我国在该领域的研究刚刚起步,为促进我国CCS的研究工作,对国内外的研究现状进行了综述,从研究领域、研究角度和研究方法总结了发展趋势,并指出了目前研究中还需要进一步加强的领域。  相似文献

正2060年前实现碳中和的目标为我国能源转型提出了明确的方向,相关研究表明,2060年前实现碳中和,需要到2050年左右实现能源系统的近零排放。实现该路径的技术选择包括大规模的可再生能源、核电的使用,以及化石能源使用的CCS技术(碳捕集与封存)。不同的研究对这些技术的前景给予了不同的判断,也提出了各不相同的产业技术选择。主流的研究成果包括高比例可再生能源,以及CCS技术应用的情景。截至目前,各方研究对实现近零排放时能源供应的安全性,特别是高度安全性的讨论还不多,本文将就这一议题进行分析,讨论在能源供应高安全度前提下的能源供应体系,以进一步明确实现我国碳中和目标下能源系统再构建的方向。  相似文献

<正>碳达峰、碳中和目标的提出进一步增强了实施绿色低碳发展的重要性和紧迫性,能源领域需要深入推进能源革命,稳步实施能源生产结构、消费结构的优化调整,逐步构建适合经济社会发展和生态环境保护要求的新型能源体系。“双碳”背景下,减碳控排已成为燃煤电厂必须深入研究的课题,碳捕集利用与封存是燃煤电厂减碳的重要技术方式,对于碳中和目标的实现具有保障推进作用,做好技术研究和市场调研等相关工作,有助于燃煤电厂在碳捕集利用与封存规模化发展阶段把握发展机遇。  相似文献

This article analyzes the engagement of Japanese, Korean and Chinese participants in the development of Internet standards at IETF on the basis of four quantitative metrics: attendance, patenting, authorship and leadership. The results are strikingly divergent. Japanese involvement in Internet standardization began early and Japan was, for many years, second only to the U.S. in terms of IETF participation. Though Japanese participation has declined since the early 2000s, Japan remains a major contributor to IETF standardization. Korean involvement in IETF has always been significant, but below the levels of Japan and major European countries. Korean participation in IETF has also declined over the past decade, and has been dominated by one firm, Samsung. Though meaningful Chinese involvement in IETF did not begin until the mid-2000s, it has rapidly expanded in recent years. Today, China is a major player in numerous areas of Internet standardization in terms of three metrics (participation, patenting and leadership), and is rapidly gaining in terms of document authorship as well. Most of China׳s recent IETF involvement can be attributed to Huawei, though other Chinese firms have recently begun to increase their participation in the organization. Thus, contrary to some views that China׳s engagement with standardization is primarily one of indigenous innovation and “catching up”, China׳s experience with IETF demonstrates deliberate and effective engagement with a major Western standards-development organization on its own terms.  相似文献

This paper explores the idea that a sense of school subject image is a necessary feature of curriculum management and a potent force for change. The discussion centres on the view that all school subjects have an image and that if those intimately involved with the subject do not control the image then someone else does! In such circumstances the image is the product of past encounters and old euphemisms and is unlikely to hold the changed realities.The UK developments in Design and Technology education (the term Design and Technology is used to denote the school subject defined under this heading by the UK National Curriculum, 1995) have created something of an image problem which has interesting international parallels. Some of these problems are due to clearly discernible internal tensions and an ambiguous relationship with other subject areas.Through greater attention to subject image internal controversies might be acknowledged and resolved, relationships with other subject areas can be more meaningfully understood and practitioners can be helped to make sense of curriculum change.  相似文献

This special section aims to investigate the interaction of global and local forces in shaping agrifood governance. It starts from the recognition that a multitude of actors and norms shape today’s agrifood system. The resulting opaqueness of the systems makes it extremely difficult to understand and explain processes and outcomes of agrifood governance. Given the sustainability challenges facing the agrifood system, improvements in our understanding of what the interaction of global and local actors and norms means on the ground are urgently needed, however. The section, therefore, analyses agrifood governance in India across a selected group of cases. It does so by employing a systematic framework emphasizing the material and ideational dimensions of power and their interaction. The section has chosen India as the setting in which to analyze this interaction due to the crucial role the food demand and supply of this rising power plays in today’s agrifood system. This article provides the special sections’ analytical framework, which uses the interplay of material and ideational dimensions of power as a focal lens. In addition, the article applies this framework to an empirical study of the political conflict around GMO foods in India, specifically the case of ‘Golden Rice’.  相似文献

We analyze the state of the art of indicators on e-government, e-health, e-procurement and e-participation. We survey the main methodological properties of these indicators, and highlight their heuristic potential. Further, we address empirically the issue of the explanation of the availability scores, i.e. how the supply of the various e-services in each country is affected by political, institutional and socio-economic differences, and is followed by actual usage. The econometric analysis uncovers the importance of broadband penetration and higher education as drivers for most of the types of e-services and users (citizens and businesses). Moreover, a corruption-free and agile public sector proves to be an important pre-condition for more effective supply and usage. Despite data limitations and the complexity of the underlying diffusion phenomena, our study is the first truly longitudinal contribution aimed at disentangling the common drivers of such an important phenomenon – the e-services availability and usage across European countries. As such, this work appears useful to inform the policy debate and practice, in a phase characterized by a prospective reorientation of the public e-services provision and policy agenda.  相似文献
