以石墨烯、碳纤维为代表的先进碳材料产业链是江苏省重点培育的优势产业链之一,整体产业规模、创新能力、企业质态均处于全国领先地位,但对标国际先进水平,江苏先进碳材料产业链仍存在产业规模化程度小、技术水平有待提升、龙头骨干企业带动能力弱、产业生态体系尚不完善等问题。文章研究了江苏先进碳材料产业的未来发展趋势,并提出了推动江苏先进碳材料产业高质量发展的具体路径,包括强化产业链顶层设计和统筹部署、提升产业链技术创新的整体效能、积极推进产业链协同创新平台建设、搭建供需对接和产学研交流平台等。 相似文献

以石墨烯、碳纤维为代表的新型碳材料产业链是江苏省重点培育的优势产业链之一,常州作为江苏省碳材料产业发展的重点区域,以新型碳材料集群入围国家先进制造业集群。对标国际先进水平,碳材料集群存在价值链低端锁定的风险、某些关键核心技术受制于人、先进制造业成本偏高等短板,根源是产业链与创新链互融互促不足。文章研究表明,推动常州碳材料产业链与创新链融合发展的对策包括:注重规划引领,从顶层设计推动双链融合;注重需求导向,提升产业链整合创新资源的能力;注重技术驱动,提升创新链供给能力和服务水平;注重要素配套,完善影响双链交融的资金链和人才链;注重信息融通,构建双链对接的全流程科技服务体系等。 相似文献

本文首先运用投入产出模型计算陕西省各工业部门的完全碳排放系数进而测算出各工业部门出口隐含碳的排放量,发现陕西省出口隐含碳的重点部门分布于金属矿加工制品业、石油化工业、设备及计算机制造业等几个完全碳排放系数较大的工业部门.其次运用情景模拟的方法研究征收碳关税对陕西省工业品出口的影响,最后研究了征收碳关税对出口总成本以及碳成本率的影响.结果表明,碳关税的征收不仅会使各部门工业品的出口贸易量呈现不同程度的下降,并且会使陕西省工业品的出口成本大大提高.因此,陕西省政府部门应出台相关政策做好准备积极应对国际碳关税的征收,推行低碳技术,发展低碳经济. 相似文献

Adam Schwarz 《Bulletin of Indonesian Economic Studies》2010,46(2):181-185
Indonesia has responded to worldwide concern about climate change by committing to significant carbon emissions reductions over the next decade. Achievement of this goal will face significant practical obstacles, and the opportunity cost of avoided deforestation is considerable. In our second Policy Dialogue, two climate change experts present contributions to the debate. This exchange could not be more timely, given Norway's recent offer of substantial development assistance to Indonesia in return for reductions in deforestation and forest degradation.
In this first contribution, Adam Schwarz canvasses abatement options and outlines barriers to abatement and its measurement. These include capacity and data constraints, obstacles posed by decentralisation, and problems in identifying and measuring the costs of abatement measures. The author urges Indonesia to embrace the opportunity a lower carbon growth trajectory presents, and argues that this will require substantial additional funding, including from developed countries, and sustained leadership.

Analysis of regional carbon allocation and carbon trading based on net primary productivity in China
Ecological balance and carbon sink economies have gained increased attention for tackling global warming. Based on an improved Carnegie–Ames–Stanford Approach model, this study demonstrated regional Net Primary Productivity (NPP) and analyzed regional carbon overdraft situations in China during 2005–2015. Regional carbon allowances were allocated according to carrying capacity of carbon sequestration and China's carbon intensity reduction goals in “13th Five-year plan”. Data Envelopment Analysis (DEA) technology with panel data was further employed to estimate potential benefits resulting from carbon trading and a carbon sink economy. Regional NPP decreased from south to north and from coast to inland, while regions with severe carbon overdrafts were gathered in North and East China. In order to maintain a regional carbon balance with lower abatement costs, regional cooperation of emission reduction within either North or East China is proposed in this study. It is concluded that the majority of provinces and cities in Eastern China and some provinces in the west would be the major purchasers of carbon credits under a national carbon emissions trading (CET) market. Following the introduction of emissions offset mechanisms, Yunnan, Sichuan, and Heilongjiang would be the major providers of carbon sinks in China. 相似文献

This article examines how to account for the welfare effects of carbon dioxide emissions, using the historical experiences of Britain and the USA from the onset of the industrial revolution to the present. While a single country might isolate itself from the detrimental effects of global warming in the short run, in the long all countries are unable to free ride. Thus, we support the use of a single global price for carbon dioxide emissions. The calculated price should decrease as we move back in time to take into account that carbon dioxide is a stock pollutant, and that one unit added to the present large stock is likely to cause more damage than a unit emitted under the lower concentration levels in the past. We incorporate the annual costs of British and US carbon emissions into genuine savings, and calculate the accumulated costs of their carbon dioxide emissions. Enlarging the scope and calculating the cumulative cost of carbon dioxide from the four largest emitters gives new insights into the question of who is responsible for climate change. 相似文献
