应对气候变化需以生态文明理念构建全球技术合作体系

气候变化是人类发展过程中遇到的最大全球性环境问题,也是最大的外部性问题。IPCC报告显示,实现本世纪末温度升高不超过2度的目标,需要全球经济和能源系统深度的低碳转型,并在本世纪下半叶达到温室气体的净零排放。应对气候变化因此面临着前所未有的技术创新与合作需求。2015年底达成的《巴黎协定》提出了落实技术开发与转让的长期愿景,主张对气候变化领域的技术创新给予政策和资金支持,使发展中国家在技术周期的早期阶段就能够获取必要的技术,从而为实现全球应对气候变化提供保障。然而,基于工业文明的传统技术创新与合作模式难以满足保护全球气候的技术需求。减缓与适应技术是气候变化挑战下全球命运共同体的公共财富。为保证其足够的供应,必须超越追求私人利益最大化的狭隘,基于生态文明理念构建全球应对气候变化的新型技术合作体系。其核心是:实现多赢的合作目标,遵循"生态人"的合作原则,体现协同的合作内容,基于互信的合作形式,鼓励多元主体的参与,促进合作成果的分享。中国作为新兴发展中大国,对应对气候变化技术国际合作有多元的利益需求。为有效落实《巴黎协定》,亟需以加速国际合作为契机,积极谋划中国应对气候变化技术对外合作的总体方略和具体行动,有针对性地制定与发达国家、其他发展中国家及欠发达国家间优势互补的合作计划,探索并引导"南-北-南"三方技术合作等新形式。     

Low-carbon society creation and socio-economic structural transition in China

China is facing the problem of climate change, environment protection and energy security. Therefore, China has to create a low-carbon society to address them. The purpose of this paper is to make a comprehensive and in-depth analysis of China’s reality and transition to a low-carbon society. The research indicates that China’s transition to low-carbon society will inevitably meet many difficulties under the relatively backward situation of China’s socio-economic structure and technologies at the current stage. Therefore, China has to take concrete policies and countermeasures to promote its development gradually. In particular, China has to vigorously promote the innovation of low carbon system, technologies, subsidy and tax, financing and investment to lay groundwork for comprehensive development of low-carbon society.     

城市创新能够驱散雾霾吗?--基于空间溢出视角的检验

中国多城市群大范围持续遭遇雾霾等空气环境问题,不仅严重影响着人民生活健康,同时成为制约中国社会经济发展的主要瓶颈。创新驱动作为引领发展的重要源泉,是治理城市雾霾的重要手段。因此,本文利用2004—2016年中国地级市PM_2.5浓度、创新等数据,基于STIRPAT模型,通过空间计量方法在同时考虑空间横向维度及时间纵向维度下就中国城市创新对雾霾的影响进行了实证分析,并进一步从城市创新对雾霾的动态效应、作用距离阈值等多个角度进行了稳健性检验。实证结果表明:①中国城市雾霾污染呈现明显的空间溢出效应和高排放俱乐部集聚特征。②中国城市创新具有积极的减霾作用。从横向空间维度来看表现为积极的空间溢出效应,但存在一定的有效距离阈值。从纵向时间维度来看,减霾效应整体存在边际递减态势。③交通便利化及能源效率的提高有效抑制了城市雾霾污染的加剧,以煤为主的能源结构仍是城市雾霾污染加剧的一大诱因。基于上述事实,本文提出以下政策建议:中国在城市雾霾治理过程中应实施科学规划,布局联防联控。防止城市"单边"治霾努力成果被周边城市的"泄漏效应"所削减;聚集创新要素,打造创新型城市引擎。在城市群内部形成创新竞争、合作机制,创新重塑城市群发展模式以缓解城市雾霾污染;考虑到城市创新对于雾霾治理红利存在边际递减态势,除上述减霾渠道外,治霾政策仍需坚持从源头着手,优化产业、能源结构,促进能效、路效提高,最终成就美丽城市。     

Climate Change Responsibility and China’s Endeavor

The problem of climate change is a global challenge.It is closely associated with social development and human survival,and it has a significant impact to all countries on energy development,economic competitiveness,technological innovation,and way of life.In recent years,with the rapid economic development in China,there is a rumor that the rapid growth of China’s carbon dioxide emission offset the efforts of the international community in reducing emissions,and China should bear the international responsibility corresponding to its significant role in greenhouse gas emission,which obviously are unfair and not objective.As this paper reveals,"China environment responsibility" that is the socalled "China environment threat" or theories,China has made a positive contribution to addressing the climate change in the past and China will still be the backbone on the protection of global climate in the future.     

An in-depth view of climate change:addressing climate change while making a transition on the development mode

While fossil fuels greatly contribute to human society,they pose great challenges to natural resources,the environment,and climate change.Developed countries,like the United States,formulated strategic measures to ensure their sustainable development and leading positions in the world.These measures include new green policies,development of shale gas,revitalization of nuclear power,energy independence,reindustrialization,and new low-carbon development based on a combination of Internet technology and renewable energy.Developing countries are also trying to introduce balanced strategies of poverty alleviation and sustainable development.Globally,industrial civilization is being transformed to ecological civilization and green,low-carbon development is a global trend.Addressing climate change provides new strategic factors to further this development.China should take substantial actions to realize sustainable development in a new road:China is in the critical stage of changing its development mode,so it is vital to choose an appropriate development path.This extensive development comes at the high price of consuming too much resources and scarring the environment.Mitigation and adaptation strategies for addressing climate change can help the transition of development.Based on the analysis of the development data of developed countries,the author introduces the concept of"two-type developed countries"with an understanding that not all developed countries must take the same development mode.He also holds the view that China should achieve modernization in a more energy-saving and more carbon-efficient manner compared with that of two-type developed countries.An analysis of"two competitions"that China is facing shows that changing the developing mode is urgent and China should grasp this opportunity in the next five to ten years,which is a key period for this transition.This paper discusses the low-carbon development goals and the three-step process.Low-carbon development does not necessarily restrict economic development.It,however,can expedite the transition of the development mode and this is a low-carbon and green development path.Transition of the development mode includes implementation of China’s green and low-carbon energy strategies,low-carbon society construction,development of agriculture and forestry,garbage sorting and utilization,innovation of urbanization,etc.Improvement of national infrastructure construction includes water safety,environment and climate monitoring system,intelligent energy web,basic database,etc.Addressing climate change can significantly improve the nation’s basic research level.In summary,it mitigates backward production capability,extensive development,and environmental damage while promoting technological advancement,scientific development,and ecological civilization.     

Energy revolution:for a sustainable future

The discovery and use of fossil fuels have not only helped the evolution of human society from agricultural civilization to industrial civilization,but also caused serious environmental and climate problems.The earth is calling for a sustainable future,and a change from industrial civilization to ecological civilization based on the new"energy revolution".A macroscopic quantitative analysis of China’s environmental capacity and climate capacity shows that China is in urgent need of changing the extensive developing mode and having an energy revolution.It is foreseeable that fossil fuels will remain the most consumed source of energies in China now and in the next few decades.Although the efficient and clean use of fossil fuels are very important,this is not an energy revolution or the fundamental solution to environmental and climate problems.Unconventional gases including shale gas play an important role in the mitigation of environmental problems and climate change,but"shale gas revolution"or"shale gas era"is not suitable to China since the proportion of natural gas in primary energy structure in China can only be increased by a maximum of 20%.The transition of Chinese energy structure from fossil-fuels-dominating stage to multiple-energy-sources stage and then to a nonfossil-fuels-dominating stage is the inevitable future,with the help of great contribution from renewable energy and nuclear energy.Among renewable energies,the proportion of non-hydro renewable energies will gradually increase.Improvement of their market competitiveness(economic efficiency)relies on technological innovation.Renewable energies will be the main energy source for the earth in future.Despite the impact of the Fukushima nuclear disaster,the whole world,including China,will not give up nuclear energy development.Safe,steady,and large-scale development of nuclear power is a rational choice of China.Transition from nuclear fission power plant to nuclear fusion power plant is the inevitable future.Nuclear energy will be a sustainable energy source and another main energy source of the earth in future.China needs to enhance energy security consciousness,promote energy saving,and change the energy supply-demand patterns,that is the transition from"meet a too-fast-growing demand with an extensive supply"to"meet a reasonable demand with a rational supply".All countries need to work together to address global environmental problems and climate change.Energy revolution is the foundation for a sustainable future.With a wide range of international cooperation,the win-win cooperation is the only way of overcoming these challenges.     

中国2020年碳减排目标下若干关键经济指标研究

《国民经济和社会发展第十二个五年规划纲要》将能源消耗强度和CO2排放强度作为约束性指标。实现2020年单位GDP碳排放强度下降40-45%的自主减排目标是中国今后发展的战略性任务。"十一五"期间,中国以能源消费年均6.6%的增速支撑了国民经济年均11.2%的增长,累计节能量达到6.3亿t标煤,CO2减排量达到14.6亿t,为全球应对气候变化做出了积极贡献。但单位GDP的能耗强度和碳强度下降与温室气体排放总量的上升还将是中国当前和未来很长时期温室气体排放的主要特征。根据历史数据分析,GDP增长、经济结构、产业结构、能源结构等都会对中国的碳减排产生重要影响。GDP增速高必然呈现高能耗、高排放的特征。经济结构方面,影响能耗和碳排放的是GDP(最终需求)的组成变化,即消费、投资和净出口的变化。由于第二产业在国民经济中所占的较大比重以及重化工产业长期存在,除了继续依靠技术进步提高能源使用效率外,必须重视产业结构调整对降低碳排放强度的贡献。能源结构对节能和碳减排的影响集中体现在资源禀赋不平衡、供需分布不平衡、消费种类不平衡。文章提出实现碳减排目标,必须控制和达到以下关键指标:控制GDP增速在6-8%之间;调整出口结构,提升服务贸易比重至30%左右;提高第三产业比例至47%以上,控制高能耗工业比重在22%以下;提高非化石能源比重至15%。此外,实现碳减排目标还必须:充分认识碳减排对转方式、调结构的重要意义;切实加强对不同区域碳减排工作的分类指导;提前部署重大低碳技术和重点领域技术研发;大力倡导绿色低碳消费和生活方式等。研究表明,中国实现2020年CO2自主减排目标还需付出更大的努力。     

长江经济带科技创新与绿色发展的耦合协调及其空间关联

绿色发展是长江经济带战略的首要要求,而创新是驱动区域绿色发展的核心要素。通过构建科技创新与绿色发展综合评价指标体系,以长江经济带108个地级及以上城市为研究对象,采用熵权Topsis法,耦合协调度模型和空间马尔科夫链方法,分析2006～2016年长江经济带科技创新与绿色发展的耦合协调水平、时空分布格局以及空间关联性演变。研究结果表明研究期内:(1)长江经济带科技创新和绿色发展指数总体上虽然均有一定的上升,但整体水平较低,2013年开始呈现同步增长的趋势;(2)科技创新与绿色发展的耦合度及协调度指数整体上呈上升趋势,但带内空间分异明显,长三角地区协调度明显高于其他地区;(3)科技创新与绿色发展的协调性呈现集群化现象,且具有"下游中游上游"的梯度化空间分异特征,低水平协调的城市单元可以划分为科技创新领先区、绿色发展领先区和平衡区3种类型;(4)科技创新与绿色发展协调性具有明显的空间溢出效应,长江经济带内相邻城市协调度的变换具有趋同特征。最后,提供了相关政策建议。     

中国低碳城市试点的政策设计逻辑

政策试点是中国国家治理策略体系的重要组成部分,是中国政府遵循“由点到面”逻辑以试验手段制定政策的一种常规性工作方法。低碳城市试点是中国应对气候变化战略的重要组成部分,通过选择不同类型、不同发展阶段、不同资源禀赋的地区开展试点,探索经济增长与碳排放脱钩的模式。现有文献侧重低碳城市建设的内涵、建设模式与路径、温室气体的核算方法、政策手段、峰值研究与达峰路径、效果评估等,有力地支持了低碳城市建设决策,但对于低碳城市试点的政策设计鲜有涉及。本文从政策过程理论、央地关系两个视角,结合府际学习与竞争关系,建构了中国低碳城市政策“试点–扩散”机制与政府行为的分析框架。中国的低碳城市试点具有探索型开拓性、综合型专业性、授权型自主性的特点,结合三批低碳城市试点的文件要求和实践进展,从政策试点的选点、设计、执行、监督和评估五个方面对于中国低碳城市试点进行了系统的梳理分析。相较于经济领域的其他政策试点,低碳城市政策试点具有弱激励弱约束的政策环境。地方政府基于自身的学习能力和领导力,在政策创新方面表现出争先、自主、效仿和守成四种行为特征,并以杭州、深圳、镇江、成都四个表率城市做了实证。政策“试点-扩散”的过程从本质上讲是中国政策创新与扩散的过程,可能在现实中需要往复多次进行,中国已陆续开展的三批低碳城市试点工作就遵循这样的政策逻辑。试点的意义是试出问题、解决问题、积累经验。从前三批试点城市评估结果来看,试点城市在低碳发展目标设定、转型路径探索和低碳发展动力转换等方面与社会的预期仍有差距,为此本文提出了推进低碳城市建设的四点建议:一是激发城市低碳发展的内生动力;二是完善低碳城市试点的科学论证机制;三是建立激励与约束并举的长效机制;四是强化市场公平竞争的政策导向。     

Climate Change Responsibility and China＇s Endeavor

The problem of climate change is a global challenge. It is closely associated with social development and human survival, and it has a significant impact to all countries on energy develop- ment, economic competitiveness, technological innovation, and way of life. In recent years, with the rapid economic development in China, there is a rumor that the rapid growth of China＇s carbon dioxide emission offset the efforts of the international community in reducing emissions, and China should bear the international responsibility corresponding to its significant role in greenhouse gas emission, which obviously are unfair and not objective. As this paper reveals, ＂China environment responsibility＂ that is the socalled ＂China environment threat＂ or theories, China has made a positive contribution to addressing the climate change in the past and China will still be the backbone on the protection of global climate in the future.     

中国对外直接投资影响母国环境的理论机理与实证研究

经济全球化背景下,中国工业化进程深度融入全球价值链分工体系,在以资源能源消耗与要素投入增加为特征的粗放型经济增长模式下,国际贸易与国际投资在带动中国经济迅速发展的同时,也不可避免地影响国内的资源环境形势。基于此,本文以中国为研究对象,探究对外直接投资对母国环境的影响及其作用机制,对于“一带一路”战略背景下中国改善生态环境质量、推动经济绿色发展,具有重要的现实意义。本文首先从经济规模扩张、产业结构转型以及技术水平增进等三个视角,构建起对外直接投资影响母国环境的理论框架,并提出相应研究假说。随后,基于中介效应法,构建动态面板模型,在核算各省综合污染指数基础上,结合省级面板数据与系统GMM估计方法,实证探究对外直接投资对母国环境的基本影响,并对其作用机制进行了检验、识别与分析。多个角度开展的稳健性检验依然表明实证结果是稳健的。研究结论如下:一是对外直接投资通过推动母国经济规模扩张,导致其污染物排放增加;二是对外直接投资通过促进母国产业结构朝向服务化转型,有利于减少其污染物排放;三是对外直接投资通过引致反向技术溢出效应,有利于母国污染物排放减少;四是综合来看,当前中国推动对外直接投资,有利于减少母国污染物排放。最后,本文从优化国际投资结构、强化技术领域国际合作等方面提出促进中国环境治理的政策建议。     

Geopolitics of global climate change and energy security

Currently,the problem of climate change is already far beyond the category of scientific research,and it affects the economic operation mode,interests pattern,and geographical relationships and becomes the focus of global governance.During the transition period of the international economic and social development and the critical transformation period of the world geopolitical pattern reorganization,China’s industrialization is still at the intermediate stage,and tackling with climate change is also China’s internal demand under this development stage.With more influence of climate change on national competitiveness,climate change and geopolitics present complex multiple relations,and climate change in the era of geopolitical landscape gradually affected the national strategy and diplomacy.This article offered some relevant suggestions based on evaluating the new geopolitical characteristics of climate change:(1)weighing of interests and properly handling the complex relations among major powers during international climate negotiations;(2)strengthening risk judgments and actively cooperating with the United States and the European Union on energy and climate change;(3)relying on the"One Belt(Silk Road Economic Belt)and One Road(twenty-first century Maritime Silk Road)"to ensure China’s energy security and actively participating in the global energy governance;(4)strengthening the"south-south cooperation"mechanism innovation and increasing the investment.     

应对气候变化关键技术创新差异的时空格局——以“一带一路”沿线国家为例

技术是应对气候变化的重要手段,关键技术创新差异的扩大将不利于各国应对气候变化的协同发展。以技术产出的专利为数据源,运用大数据挖掘工具、泰尔熵指数及空间计量学的方法和理论,分析了"一带一路"沿线国家应对气候变化关键技术创新差异的时空格局演变情况。研究结果表明:(1)沿线国家应对气候变化关键技术创新差异整体上呈现下降态势,并以初期震荡向后期平稳有升过度。(2)按地理位置划分的区域技术创新差异呈现高的空间集聚效应,且强强集聚与弱弱集聚具有一定时期内的稳定性,部分地区面临陷入技术贫困陷阱风险。(3)沿线各国应对气候变化技术创新差异存在趋同俱乐部现象,个别国家随时间推移可能经历不同俱乐部过度。针对这种趋同特征及各国技术需求特点可划分为4种类别:技术转出区、技术转入区、技术扩散区和技术承接区。技术转出区多集中在东欧某些经济发达、能源依存度高的国家。为此,本文提出如下建议:(1)各国根据自身情况制定减排政策的同时,需要国际社会制定与其相适应的差异化且有侧重的援助方案。(2)技术创新强国在涉及应对气候变化技术转移知识产权等事项上应该给予技术需求国让步。同时,技术转移应考虑区域协同及地理邻近的扩散。(3)中国应发挥好南南合作援助基金的作用,加强特定区域内共性技术的帮扶力度,建立与适宜国家间关键技术联合研发与示范机制,树立大国形象。(4)中国应加快沿线战略布局,根据不同区域各国应对气候变化的现状及其技术能力制定差异化的产业和技术转移的政策,加强与沿线国家的技术合作与贸易往来,形成优势互补的产业链。     

基于链环回路模型的低碳技术创新发展策略

低碳经济的发展已成为国际共识,低碳技术创新是发展低碳经济的核心举措.根据技术创新理论和技术创新链接模型,从技术系统和管理系统的角度分析了低碳技术创新的结构,并构建了一个基于链环回路模型的低碳技术创新发展模型,以期探讨从低碳技术创新层面推进低碳经济发展的思路.本研究提出低碳技术创新价值链应建立于社会使用的基础上,该创新价值链始于社会生活的潜在需求,经由低碳技术的发明与创造、示范与推广、重新设计与生产,终于服务顾客,注重市场的反馈以及技术系统与管理系统的密切配合,以使低碳技术创新价值链持续运作并充分挖掘镶嵌于技术创新社会价值中的经济价值.研究结论是:应强化低碳技术创新技术系统以实现社会价值与市场价值整合、通过示范强化技术系统与管理系统的链接以及强化低碳技术创新管理系统以提离产业附加值.     

“十二五”以来中国应对气候变化政策和行动评述

基于广泛系统的文献梳理和总结,凝练了“十二五”以来中国应对气候变化政策和行动的现状、特点及成效,并提出针对性建议。主要结论包括:从外部环境看,国际形势对中国应对气候变化事业的推动作用呈现递减态势,之前“以外促内”的国内气候治理特点逐步转化为“内生动力为主”和“内外协调”;从政策制定和执行模式看,“集思广益”“上书模式”持续,“上下互动”“智库支持”的政策学习特点更加明显;从政策体系上看,已经形成相对成熟的符合中国国情的完整体系,推动气候治理能力显著提高;从政策总体特点看,呈现规划主导并引领、行政手段先行市场机制跟进、由点到面有序扩展、环境与气候协同治理、中央和地方互动博弈形成动态平衡、短期内政策成本较高等特点。“十二五”至今,中国应对气候变化政策行动效果明显,提前实现了2020年应对气候变化目标,并在污染治理、经济发展等方面产生广泛协同效应。“十三五”中期以来,中国应对气候变化组织管理机构进行了重大调整,从中央到地方气候政策和行动进入调整阶段。同时,更加强调气候政策和环境政策的协同。展望未来,中国应对气候变化政策和行动应该尽快走出调整期,充分利用新体制的优势,以碳总量控制目标为抓手,坚定推动以全国碳排放权交易为中心、多措互补的政策体系,注重适应行动以应对不断放大的气候风险,继续提高公众对应对气候变化政策的认知度、接受度和参与度,并不断加强技术研发和储备。     

光伏市场拉动研发创新的国际研究

光伏的高成本仍然阻碍着它的大规模应用,由于技术创新是成本下降的重要因素,如何实现市场对创新的拉动作用是具有现实意义和理论价值的问题.本研究从市场发展态势的角度分析如何实现市场对创新的拉动作用.首先结合光伏产业特点和技术创新学中的相关理论,提出关于不同阶段的市场态势对市场拉动创新的影响的理论假说.然后建立市场发展态势指标和市场动力检验模型,从而利用20个国家的市场与专利历史数据进行跨国比较分析,根据计量结果识别出市场发展态势对市场发挥拉动创新作用的影响.实证结果表明20个国家中70％的市场发挥了拉动研发创新的作用;在市场培育初期持续过小的市场拉动创新不显著,该发展态势可用技术扩散模型中p指标进行判断;在市场发展加速期急剧扩大的市场拉动创新不显著,该发展态势用技术扩散模型中q指标进行判断.因此,为了促进成本降低,光伏市场政策应主导市场规模实现平稳持续型增长.     

Combating climate change calls for a global technological cooperation system built on the concept of ecological civilization

Climate change has been considered as the most paramount global environmental problem and the biggest externality throughout the history of human development. Accordingly, the world is facing unprecedented technological innovation and collaborative demands to deal with climate change. In the 2015 Paris Agreement, a long-term vision of technology development and transfer implementation was proposed, and policy and financial support for technological innovation in the area of climate change was advocated. These terms aim to enable developing countries to acquire the necessary technology in the early stage of the technology cycle to address climate change challenge. However, the traditional technological innovation and cooperation mode based on industrial civilization can hardly meet the technical demands of global climate protection. To ensure the continuous development and deployment of technology in a required scale and pace, a new global technical cooperation system is proposed to develop based on the philosophy of ecological civilization. The core contents of this system are supposed be as follows: to implement all-win cooperation targets, adhering to cooperation principles of Eco-man, adopt cooperation content that reflects synergy, pursue cooperation based on mutual trust, encourage participation of multiple actors, and promote sharing of cooperative outputs.     

“水十条”对工业水污染强度的影响及其机制

《水污染防治行动计划》(简称“水十条”)是国家为切实加大水污染防治力度,保障国家水安全而制定的法规。为检验“水十条”的政策影响效应,文章利用2012—2017年全国269个地级市的数据,结合工业化程度、对外开放水平、技术进步、人口规模、水资源禀赋等控制变量,运用双重差分法对“水十条”政策实施是否有助于减轻工业水污染强度进行研究。研究发现:我国中西部地区由于产业结构、技术水平等原因,工业水污染强度显著高于其他地区,“水十条”政策实施显著降低了中西部地区工业水污染强度。通过改变政策实施时间、剔除中心城市、增加控制变量以及剔除严重污染等方式进行重新回归,检验结果依然具有较强稳健性。进一步分析中,文章研究了产业结构以及技术创新的作用机制,发现第一产业比重显著降低,而第三产业显著提升,产业结构得到优化,并且技术创新效应显著加强。结果表明,产业结构升级以及技术创新均为“水十条”政策改善工业水污染强度的有效途径。在空间异质性方面,在环境规制强度较高的地区“水十条”政策对工业水污染强度的影响相对较小;而在环境规制强度较低地区却呈现出较强的抑制作用,主要原因在于环境规制强度高的地区水污染情况原本较好,因此污染强度降低幅度较小。因此,文章认为“水十条”政策能够显著改善工业水污染强度,并且加上环境规制、技术创新以及产业结构优化等手段的辅助能够更好地发挥政策效果。文章的发现为中国水污染防治行动提供了有益的政策启示。     

气候变化研究的中国知识贡献及其影响局限

气候变化知识的不断深化和积累是全球气候治理的基础。政府间气候变化专门委员会(IPCC)邀请全球有代表性的科学家,通过分析评估国际上正式发表的文献,提供关于全球气候变化科学进展的最新认识结论。本文基于文献计量学,通过统计中国在气候变化十大重要领域的科技成果产出量和影响力、中国政府和科学家对IPCC评估报告的参与以及中国大陆引文在IPCC第五次评估报告中的贡献,分析了中国对全球气候变化知识的贡献与局限。结果表明:近十年来,中国在气候变化大多数领域的科技成果产出量已居全球第二或第三位,但在海洋与气候变化、适应气候变化和全球气候治理领域的国际论文量明显落后;与美国和英国相比,中国气候变化科技成果的各类影响力指标明显偏低;中国对IPCC评估报告的参与度和影响力在不断提升,中国积极组织相关机构和专家参与IPCC评估工作,对全球气候治理起到了重要的科学支撑作用;但从IPCC第五次评估报告中国大陆引文的角度看,中国贡献仍整体偏弱,中国大陆引文的贡献呈领域分布不均衡,优势领域少,成果影响面窄的特点。与科学基础领域相比,中国在影响和适应、减缓和国际合作领域的科学贡献更弱,对全球视角关注不够,但中国大陆引文总体的国际科学合作活跃度较高。后巴黎时代,中国需要更加面向国家需求、气候公约和《巴黎协定》目标以及国际气候变化科技前沿,加强全球视野和原始创新,突出中国优势和特色,使气候变化的中国研究成果更多支撑全球气候治理进程的推进。     

Determinants of workers’ attitude toward low-carbon technology adoption: empirical evidence from Chinese firms

As the main contribution of China’s carbon emissions, low-carbon production in industrial firms becomes an inevitable choice, and industrial firm employees’ attitudes on low-carbon new technology directly influence the results of low-carbon production. Based on the Unified Theory of Acceptance and Use of Technology model, structural equation modeling was used to analyze the main factors influencing firm staff to accept low-carbon new technology. The study reveals that the employee’s social impact, performance expectation, effort expectations and convenient conditions, and employee characteristics are all main factors affecting their acceptance attitudes on low-carbon new technology. And social influence has the largest effect on employees’ acceptance attitudes toward low-carbon new technology. Accordingly, relevant policy recommendations are put forward for the future research direction.
