通过构建“能源-经济-碳排放”混合型投入产出分析框架,利用扩展的结构分解模型,对广东省2002-2010年能源消费碳排放的影响因素进行结构分解分析。结果显示:1)广东省能源消费碳排放从2002年的5 820.55万t增长到2010年的12 097.91万t。2)碳排放影响因素的直接效应分析,经济规模和人口增长是广东省碳排放增长的主要驱动因素,同时生产结构在当前仍然是碳排放增长的正向驱动因素,但是生产结构对于广东省碳排放增长的贡献率逐步降低。碳排放强度是遏制广东省碳排放增长的最主要贡献因子,最终需求结构对于广东省碳排放总量变化由正效应转变为负效应,逐渐成为遏制碳排放增长的主要贡献因子。3)碳排放影响因素的间接效应分析,国际出口、进口贸易和省域间调进、调出贸易对于广东省能源消费碳排放的变化影响显著。同时,固定资本形成和城镇居民消费对于广东省碳排放的增长有较强影响。4)不同最终需求对产业部门碳排放增长的分析表明,出口贸易引起的碳排放增长主要集中在电子与机械类行业和纺织服装业;省域间调出引起的碳排放增长主要集中在典型的能源密集型行业;固定资本形成引起的碳排放增长主要集中在建筑业;城镇居民消费引起的碳排放增长主要集中在交通运输业。 相似文献

确保减碳的首要任务是定量测度化石能源消费碳排放的增量影响因素及其大小。为分析北京市1997-2007年的碳排放增量,本文构建了一个扩展的(调入、进口)竞争型经济—能源—碳排放投入产出模型,从整体特征、不同产业、工业行业3个方面,对1997-2007年北京能源消费的碳排放增量进行了结构分解。分析发现:经济规模增长要素(消费、投资、调出和出口等)是拉动碳排放增长的主导因素,能源强度变动效应却是碳减排的决定性因素;在规模扩张因素中,消费和调出超过投资和出口,是碳排放增长的主要贡献者;2002以来新一轮"高碳"特征的工业化导致CO2排量呈急增之势;产业结构调整、三产比重最大使得服务业成为碳排放增长的最大部门,但工业排放的增长却后来居上;碳增排的重点行业是高能耗业,而碳减排的却是能源工业;两时段各效应在不同产业、不同工业行业的影响方向和大小不一。 相似文献

据2006—2015年间制造业能源消费数据核算中国大陆30个省（除港澳台、西藏外）的制造业碳排放，并依据要素密集度将制造业划分为资金、技术、劳动力密集型3类。在分析制造业以及不同类型制造业碳排放时空演变基础上，运用Kaya模型将碳排放驱动因素划分为经济规模、产业结构、能源强度、能源碳强度4个方面，并运用LMDI-I分解模型定量分析碳排放的驱动因素。结果表明：除北京外，其余省域制造业碳排放均呈现不同程度的增长；资金密集型制造业碳增长最高，其次是技术、劳动力密集型制造业；经济规模扩大是导致各省、各类型制造业碳增长的首要因素；产业结构调整、能源强度与能源碳强度的变化在各省、各类型制造业碳排放中呈现双向效应，且作用强度差异显著。因此，在未来，各省、各类型制造业碳减排措施应各有侧重。 相似文献

从影响因素角度用LMDI分解方法对新疆1999—2009年的碳排放进行研究。结果表明:能源结构和能源强度对新疆人均碳排放增长起抑制效应,且能源强度的抑制效应大于能源结构的抑制效应;产业规模和人口规模对新疆人均碳排放增长起拉动效应,且产业规模的拉动效应大于人口规模的拉动效应。能源强度和能源结构的抑制效应难以抵消由产业规模和人口规模拉动的新疆人均碳排放的增长。在实证研究结果的基础上提出了相应的政策建议。 相似文献

"双轮驱动"发展模式背景下,我国建设用地扩展特征明显。建设用地变化的碳排放效应是导致大气中碳排放量增加的重要因素。运用安徽省统计年鉴数据,采用改进的Kaya恒等式及LMDI分解模型,对安徽省1997-2011年碳排放的驱动因素进行了定量测度。结果表明:经济增长、建设用地扩展、人口密度变化对碳排放具有增量效应,经济增长为第一驱动因素,年平均贡献率达266.32%,建设用地扩展为重要驱动因素,其碳效应年均值为640.57万t,年均贡献率为187.30%,人口密度变化对碳排放驱动影响较小。能源结构变化、能源强度下降对碳排放具有抑制作用,年均贡献率分别为-212.06%、-58.115%。基于碳排放因素分解结果,针对性提出了碳减排的政策途径,可为政府通过合理组织土地利用,实现碳减排提供科学依据,有利于安徽生态省建设及减排目标实现,也可为省域尺度建设用变化的碳排放效应研究提供借鉴。 相似文献

能源消费是碳排放的主要来源。根据IPCC碳排放计算指南缺省值计算出广东省1990―2010年的碳排放量,并对广东省近20年来碳排放进行阶段划分,采用对数平均迪氏指数法(Logarithmic Mean Divisia Index),对碳排放量进行因素分解,分析能源结构、能源效率和经济发展对碳排放的影响及作用程度。结果表明:1)1990―2010年,广东省能源消费的CO2排放总量和人均CO2排放量不断上升,万元GDP碳排放量、三次产业碳排放强度均呈下降趋势,原煤的消费是碳排放的主要来源,第二产业的CO2排放量比重最大,但呈缓慢下降趋势;2)经济发展效应对广东省能源消费碳排放的贡献率最大,其次是能源强度效应、人口规模效应,能源结构效应的贡献率最小;经济增长是碳排放量增加的主要推动因素;能源消费强度影响碳排放量的增速,能源消费强度又进一步受到产业结构和各产业能耗强度的影响,其中,第二产业能耗强度和第二产业产值比重是影响能源消费强度最主要的影响因素。 相似文献

准确查清典型省份能源消费碳排放的实际情况及其碳排放增长的主要驱动因素,是实现我国碳减排目标的关键。本文采用扩展的LMDI模型对来自中国东、中和西部地区三个典型省(区)——江苏、河南和内蒙古的碳排放增长进行了比较分解。结果表明:(1)1996–2017年,3个省(区)的能源消费碳排放变化呈上升趋势,但各省(区)之间存在明显差异。(2)各驱动因素对碳排放的影响在不同省份和不同经济发展期明显不同。经济增长对各省碳排放变化的正向贡献最大(1996–2017年,河南、江苏、内蒙古三省(区)经济发展对碳排放增长的贡献分别为307.19%、205.08%和161.26%);其次是城镇化和人口规模,但对碳排放增长的贡献远小于经济增长。(3)除"十五"规划期外,能源强度在促进3省(区)碳减排方面发挥了主导作用,其次是能源结构。在所有抑制碳排放增长的因素中,农村人口比例的贡献最小。此外,城乡居民人均能源消费对碳排放的影响在不同省份(区)和不同经济发展阶段均表现出相对较小的影响和两面性,但在推动省域碳排放的变化方面开始起着越来越重要的作用(如1996–2017年,江苏省的居民能源消费对碳排放增长的贡献率超过7.9%,其中城镇居民人均能源消费的贡献率大于3.8%)。鉴于此,建议政策制定者应根据东、中、西部地区的碳排放省情和影响碳排放的关键因素,制定有针对性的减排措施。 相似文献

Influencing mechanism of energy-related carbon emissions in Xinjiang based on the input-output and structural decomposition analysis 总被引：1，自引：1，他引：0
Analysis of carbon emission mechanism based on regional perspectives is an important research method capable of achieving energy savings and emission reductions. Xinjiang, an important Chinese energy production base, is currently going through a period of strategic opportunities for rapid development. Ensuring stable socio-economic development while achieving energy savings and meeting emission reductions targets, is the key issue currently facing the region. This paper is based on the input-output theory, and conducts a structural decomposition analysis on the factors affecting energy-related carbon emissions in Xinjiang from 1997 to 2007; this analysis employs a hybrid input-output analysis framework of “energy - economy - carbon emissions”. (1) Xinjiang’s carbon emissions from energy consumption increased from 20.70 million tons in 1997 to 40.34 million tons in 2007; carbon emissions growth was mainly concentrated in the production and processing of energy resources, the mining of mineral resources, and the processing industry. (2) The analysis of the direct effects of the influencing factors on carbon emissions showed that the change in per capita GDP, the final demand structure, the population scale, and the production structure were the important factors causing an increase in carbon emissions, while the decrease in carbon emission intensity during this period was the important influencing factor in stopping the growth of carbon emissions. This showed that while the sizes of Xinjiang’s economy and population were growing, the economic structure had not been effectively optimized and the production technology had not been efficiently improved, resulting in a rapid growth of carbon emissions from energy consumption. (3) The analysis of the indirect effects of the influencing factors of carbon emission showed that the inter-provincial export, fixed capital formation, and the consumption by urban residents had significant influence on the changes in carbon emissions from energy consumption in Xinjiang. (4) The growth of investments in fixed assets of carbon intensive industry sectors, in addition to the growth of inter-provincial exports of energy resource products, makes the transfer effect of inter-provincial “embodied carbon” very significant. 相似文献

中国能源消费碳排放的空间计量分析(英文) 总被引：8，自引：3，他引：5
Based on energy consumption data of each region in China from 1997 to 2009 and using ArcGIS9.3 and GeoDA9.5 as technical support,this paper made a preliminary study on the changing trend of spatial pattern at regional level of carbon emissions from energy con-sumption,spatial autocorrelation analysis of carbon emissions,spatial regression analysis between carbon emissions and their influencing factors.The analyzed results are shown as follows.(1) Carbon emissions from energy consumption increased more than 148% from 1997 to 2009 but the spatial pattern of high and low emission regions did not change greatly.(2) The global spatial autocorrelation of carbon emissions from energy consumption in-creased from 1997 to 2009,the spatial autocorrelation analysis showed that there exists a "polarization" phenomenon,the centre of "High-High" agglomeration did not change greatly but expanded currently,the centre of "Low-Low" agglomeration also did not change greatly but narrowed currently.(3) The spatial regression analysis showed that carbon emissions from energy consumption has a close relationship with GDP and population,R-squared rate of the spatial regression between carbon emissions and GDP is higher than that between carbon emissions and population.The contribution of population to carbon emissions in-creased but the contribution of GDP decreased from 1997 to 2009.The carbon emissions spillover effect was aggravated from 1997 to 2009 due to both the increase of GDP and population,so GDP and population were the two main factors which had strengthened the spatial autocorrelation of carbon emissions. 相似文献

北京市服务业碳排放增长的分解分析 总被引：1，自引：0，他引：1
The output as well as carbon dioxide emissions of tertiary industry have increased continuously in Beijing. Therefore, the tertiary industry has become a new field that needs to be explored for energy saving and emission reduction. This paper calculates the direct and indirect carbon dioxide emissions of tertiary industry in Beijing from 2005 to 2012 using the input-output analysis method. The results indicate that both the direct and indirect carbon dioxide emissions increased continuously and the latter grew more quickly than the former. The growth of the direct and indirect carbon dioxide emissions of tertiary industry was decomposed, which showed that four factors influence the growth of carbon emission of the tertiary industry, including the changes of industrial scale, industrial structure, energy consumption intensity and carbon coefficient. The results show that the industrial scale advancement and the direct energy carbon coefficient change promote the increase of direct carbon dioxide emissions, while the shift of industrial structure and the change of direct energy consumption intensity have the restrain on it. The industrial scale enlargement, industrial structure shift and the indirect energy carbon emission coefficient change promote the growth of indirect carbon dioxide emissions, while the indirect energy consumption intensity change has a restrain. 相似文献

江苏省区域旅游业碳排放测度及其因素分解 总被引：4，自引：1，他引：3
区域旅游业碳排放测度是分解旅游业减碳任务的需要。依托1997年、2002年和2007年的投入产出表和旅游终端收入,以江苏省为案例地,测度了旅游业各部门包括直接和间接碳排放的旅游业碳排放总量,并利用LMDI分解了影响因素的作用机理。结果显示,旅游业碳排放总量增长较快,较均衡分布于各部门,绝大多数来自间接层面;国内游客的碳排放总量显著高于入境游客,但前者的每人次碳排放远低于后者,也远低于发达国家,还低于发展中国家;省内各地区的碳排放总量和每人次碳排放均存在着显著差异;游客规模不断扩大和旅游消费水平持续提高是碳排放增长的主要驱动力,能源强度下降和能源结构调整则对碳排放具有一定的抑制作用,收入结构变动作用具有一定的阶段波动性特征。结果表明,旅游业减碳不仅需各部门共同分担,更依赖向其提供中间产品的关联产业的大力联动;国内游客是主要碳源,需要大量排放空间;游客每人次碳排放高的地区应承担较大的减排责任;降低能源利用强度和引导旅游消费低碳发展,是旅游业碳减排的主要方向。 相似文献

Review on carbon emissions,energy consumption and low-carbon economy in China from a perspective of global climate change 总被引：2，自引：2，他引：0
Accompanying the rapid growth of China’s population and economy, energy consumption and carbon emission increased significantly from 1978 to 2012. China is now the largest energy consumer and CO2 emitter of the world, leading to much interest in researches on the nexus between energy consumption, carbon emissions and low-carbon economy. This article presents the domestic Chinese studies on this hotpot issue, and we obtain the following findings. First, most research fields involve geography, ecology and resource economics, and research contents contained some analysis of current situation, factors decomposition, predictive analysis and the introduction of methods and models. Second, there exists an inverted “U-shaped” curve connection between carbon emission, energy consumption and economic development. Energy consumption in China will be in a low-speed growth after 2035 and it is expected to peak between 6.19–12.13 billion TCE in 2050. China’s carbon emissions are expected to peak in 2035, or during 2020 to 2045, and the optimal range of carbon emissions is between 2.4–3.3 PgC/year (1 PgC=1 billion tons C) in 2050. Third, future research should be focused on global carbon trading, regional carbon flows, reforming the current energy structure, reducing energy consumption and innovating the low-carbon economic theory, as well as establishing a comprehensive theoretical system of energy consumption, carbon emissions and low-carbon economy. 相似文献
