基于ARDL模型长三角碳排放、能源消费和经济增长关系研究

碳排放量、能源消费量和经济增长间存在着密切的关系。长三角地区(研究该区域为上海、浙江、江苏,简称长三角,下同）碳减排措施的实施是否会影响长三角地区的经济增长,能源消费量、能源结构和碳排放量间存在何种联系,这些均是在长三角碳减排政策制定中亟待考虑的问题。利用1990~2010年,长三角的能源经济样本数据,使用ARDL模型和格兰杰因果检验模型（Granger）定量的研究了上述几个因素之间的关系。研究发现：当碳排放量、能源消费和经济增长分别为回归变量时,均存在其它解释变量和每个回归变量间的长期稳定的协整关系。在长期关系中,存在经济增长对碳排放量的负向弹性影响。能源消费对经济增长的影响为正,能源消费每增长1%,经济增长0.67%。碳排放量对经济增长的长期影响为负,碳排放量每增长1%,经济则减少0.49%。Granger因果关系的研究表明：滞后长度分别为3,4时,存在从经济增长到能源消费和碳排放量倒的单向因果关系。不存在从能源消费和碳排放量到经济增长的单向因果关系,且亦不存在碳排放量和能源消费的双向因果关系。在长三角,制定和实施适当的节能减排政策将不会阻碍该地区经济增长。节能减排政策的制定,应首先考虑能源结构优化,降低长三角高碳能源的消费比重     

Energy, environment and growth nexus in South Asia

The present study investigates the energy, environment and growth nexus for a panel of South Asian countries including Bangladesh, India, Pakistan, Sri Lanka and Nepal. The simultaneous analysis of real GDP, energy consumption and CO₂ emissions is conducted for the period 1980–2010. Levin panel unit root test and Im test panel unit root both indicate that all the variables are I (1). In addition, Kao’s panel Cointegration test specifies a stable long-term relationship between all these variables. Empirical findings show that a 1 % increase in energy consumption increases output by 0.81 % in long run whereas for the same increase in CO₂ emission output falls by 0.17 % in long run. Panel Granger causality tests report short-run causality running from energy consumption to CO₂ emissions and from CO₂ emissions to GDP.     

Movement towards a low carbon emitted environment: a test of some factors in Malaysia

There exists a high global concern in different nations on environmental sustainability especially at the focal stage of increased economic growth and development process due to high level of environmental degradation and pollution. The major aim of this study was to empirically examine how to minimise carbon emissions (CO₂) in Malaysia which are mainly caused by energy production, fossil fuel consumption, population density and economic growth. The study adopted the method of autoregressive distributed lag bound testing approach to analyse the data for the period 1971–2011. The study found that economic growth in Malaysia has a direct relationship with CO₂ emissions in both the short run and the long run. Similarly, there is a positive relationship between fossil fuel consumption and CO₂ emissions over the same period. Population density was found to have positive impacts on CO₂ emissions. Contrarily, the relationship between the activities of energy production and pollution is negative in the long run. The study recommends that a targeted GDP growth rate should be set with the consideration to avoid more environmental pollution. In addition, the positive impact of fossil fuel consumption on the environmental pollution implies that there is a need to make and implement policies that will encourage the use of public transportation system more than private transportations. That is, the unnecessary use of private vehicles should be discouraged in order to reduce the extent of fossil fuel consumption.     

Road energy consumption,economic growth,population and urbanization in Egypt: cointegration and causality analysis

The study investigates the causal relationships between road energy consumption, economic growth, urbanization and population growth in Egypt over the period (1980–2011). I use Johansen cointegration approach, vector error correction model (VECM), generalized impulse response functions and variance decomposition technique. The results show the existence of long-run relationship between the variables. Moreover, the results indicate the existence of unidirectional long-run causality running from road energy consumption to urbanization and from road energy consumption to economic growth which implies the existence of growth hypothesis in the long run. Also, there is bidirectional short-run causality between road energy consumption and economic growth, which indicates the existence of feedback hypothesis in the short run. These results imply that road energy consumption determines economic growth in the both short run and long run and economic growth causes road energy consumption in the short run. And according to these results, several policy implications will be suggested for policymakers. They should take into consideration while implementing energy conservation policies, the possible negative effect on economic growth and have to concentrate on technological development policies and to make a shift towards using clean alternative fuel as natural gas and focus on investment in renewable energy resources.     

无锡市能源消费、碳排放与经济增长关系分析

经济增长对资源消耗存在很大的依赖性,研究能源消费、碳排放与经济增长关系,可为经济增长方式转变和低碳城市建设提供重要科学依据。基于IPCC国家温室气体排放清单指南中的方法估算了无锡市能源消费碳排放,并建立“脱钩”模型探讨能源消费、碳排放与经济增长之间的关系。结果表明：（1）2000~2010年,无锡市碳排放从84335万t增加到2 52804万t,总量不断增加,但趋势有所减缓,且各县市碳排放特征差异显著;（2）无锡市碳排放与经济增长整体处于弱脱钩状态,且脱钩状态有不断增强的趋势,市区经济发展已不依赖于能源消费,朝着环境友好方向发展,江阴和宜兴节能减排压力仍然很大;（3）优化产业结构、调整工业结构和提高能源利用效率是改善无锡市能源消费、碳排放和经济增长关系的有效途径,各县市根据具体情况,侧重点有所不同     

Causality relationship between CO2 emissions,GDP and energy intensity in Tunisia

This article analyzes the causality between the economic growth, the energy and the environment, measured by CO₂ emissions. Our empirical study is based on a series of annual data from 1980 to 2010 in Tunisia. Our study was conducted using the Granger causality test and variance decomposition. The empirical results confirm the presence of a positive effect between the energy consumption and the economic growth measured by gross domestic product (GDP). Thus, there is a unidirectional relationship between GDP and CO₂ emissions in the short term. This analysis shows, as is common to relatively fast-growing economies in Tunisia, that the biggest contributor to the rise is CO₂ emissions. Hence, in congruence with the result of variance decomposition, the GDP affects CO₂ emissions in the short and medium term at an almost constant level (10 %). The non-renewable energy intensity in Tunisian economy is responsible for a modest reduction in CO₂ emissions, which suggests the implementation of conservation policies aimed at energy efficiency and the orientation toward renewable energy.     

中国典型资源型地区能源消耗与经济增长动态关系研究

随着国内外经济环境的复杂变化,中国资源型地区经济结构转型困难加剧。对资源型地区能源消耗与经济增长之间的关系进行研究,可以帮助该类型地区厘清经济发展过程中的能源消耗现状,对于优化资源型地区经济转型之路具有重要现实意义。本文以中国典型资源型地区山西省、黑龙江省、吉林省、辽宁省为例,选取1985—2014年数据,利用格兰杰因果分析对研究区能源消耗与经济增长之间的动态关系进行了研究。研究结果表明:1山西省表现出从经济增长到能源消耗的单向因果关系,黑龙江省与辽宁省表现出从能源消耗到经济增长的单向因果关系,吉林省表现出能源消耗与经济增长的双向因果关系;2山西省、黑龙江省、辽宁省都表现出从煤炭消耗到经济增长的单向因果关系,吉林省表现出煤炭消耗到经济增长的双向因果关系;3典型资源型地区都表现出从能源消耗到煤炭消耗的单向因果关系。4资源型地区转型务必将落实供给侧改革摆在发展首位。山西省应在提高能源使用效率的基础上选择集约化、低载能的新兴产业,黑龙江省与辽宁省应加大新能源的开发与产业化进程,产业应向高端装备制造业、现代服务业等产品附加值高、能源消耗少、环境污染小的产业转型,吉林省的重工业发展要以油气能源替代煤炭资源,在降低产业能耗的同时加速扶持已经相对成熟的替代产业,减少产业转型对于地区经济产生的负面影响。     

江苏省人口规模、结构对碳排放的影响分析

将人口结构因素纳入STIRPAT模型,利用江苏省1982~2010年的相关数据运用统计和计量方法对影响碳排放的人口总量、人口城市化、老龄人口比重、家庭规模、人均消费额、碳排放强度等相关因素进行实证分析。结果表明：家庭规模具有显著的负效应;在显著的正向影响因素中,老龄人口比重弹性最大,其它依次为人均消费额、人口总量、人口城市化水平、碳排放强度。在考虑人口结构情况下,碳排放的人口规模弹性小于1,缺乏弹性,说明人口总量对江苏碳排放的影响开始放缓;人口年龄结构对碳排放的影响逐渐显现,特别是老龄人口比重已经超过人口规模,成为促进碳排放的第一驱动因素;人口城市化进程和人均消费额直接加剧了碳排放,以碳排放强度表示技术进步对抑制碳排放有一定的作用,但不显著。针对分析结果,探讨了江苏省未来低碳发展的应对之策     

江苏省能源消费与经济增长耦合关系研究

能源消费与经济增长之间的关系是环境经济学研究的重要领域。以江苏省为研究区域，基于1990～2005年的年度数据，运用“脱钩”和“复钩”理论，协整分析技术和Granger因果关系检验方法，辨识和分析了的能源消费总量、电力消费和地区生产总值之间的耦合关系，实证研究表明，1990～2000年，江苏能源消费与地区生产总值处于弱“脱钩”状态，进入2000年后，二者呈现出扩张性“复钩”趋势。研究同时还发现江苏的能源消费总量与GDP之间存在长期均衡关系，表现出能源消费促进经济增长的单向格兰杰因果关系。研究结果表明了当前能源是影响江苏经济增长的关键要素，江苏在经济增长和能源利用战略等方面应当采取更加积极有效的对策。〖     

上海市居民消费碳排放的实证分析

居民消费碳排放是国内外温室气体排放研究的重要问题。利用1997～2010年上海市统计数据,分别采用改进的投入产出模型法、碳排放系数法核算了上海市居民间接和直接能源消费产生的碳排放,分析了上海市居民消费的碳排放变化、居民消费碳排放的城乡差异、各部门对居民间接能源消费碳排放的贡献。结果表明:(1)1997～2010年上海市居民消费产生的碳排放呈逐年上升趋势,间接能源消费是居民消费的碳排放的主要来源,在居民消费碳排放总量中占有较大比重;(2)1997～2010年上海市城镇居民消费碳排放呈逐年上升,农村居民消费碳排放呈下降趋势,居民消费碳排放存在着显著的城乡差异;(3)14个部门对居民消费碳排放的贡献大小不同,其中文教卫生商务及其他服务、交通运输仓储及信息服务、食品制造及烟草加工业3个部门对城乡居民消费碳排放的贡献最大;(4)提高各部门能源利用效率、降低部门单位产出的碳排放、引导居民向低碳产品消费的转变是居民消费碳减排的有效措施。研究结果可为上海市居民生存碳排放的评估提供数据支持,为政府部门制定碳减排措施、引导居民低碳消费提供理论指导。     

中国碳排放的因素分解模型及实证分析:1995-2004

能源消费是碳排放的主要来源。随着中国经济的快速发展,能源消费的急剧增长以及以煤为主的能源结构在短期内很难改变,因此,碳排放不可避免地会出现一定幅度的增加。本文基于碳排放量的基本等式,采用对数平均权重Divisia分解法（Logarithmic mean weight Divisia method,LMD）,建立中国人均碳排放的因素分解模型,定量分析了1995-2004年间,能源结构、能源效率和经济发展等因素的变化对中国人均碳排放的影响,结果显示经济发展对拉动中国人均碳排放的贡献率呈指数增长,而能源效率和能源结构对抑制中国人均碳排放的贡献率都呈倒“U”。这说明能源效率对抑制中国碳排放的作用在减弱,以煤为主的能源结构未发生根本性变化,能源效率和能源结构的抑制作用难以抵销由经济发展拉动的中国碳排放量增长。

Abstract

Co-integration theory has been employed in this paper and Granger causes are found between urbanization rate and GDP, between capital stock and GDP. Scenario analysis of GDP is performed using the GDP model established in the paper. The energy consumptions in Germany, Japan and other developed countries are analyzed and compared with the energy consumption in China. Environmental friendly scenario of energy demand and CO₂ emissions for sustainable China has been formed based on the results of comparison. Under environmental friendly scenario, the primary energy consumption will be 4.31 billion ton coal equivalence (tce) and CO₂ emissions will be 1.854 billion t-c in 2050; energy per capital will be 3.06 tce that is 1.8 times of energy consumed in 2005 in China and 51% of consumed energy per capital in Japan in 2003. In 2050, the energy requirement of unit GDP will be 20% lower than that of Germany in 2003, but will be still 37% higher than that in Japan in 2003. It is certain that to fulfill the environmental friendly Scenario of energy demand and CO₂ emissions is a difficult task and it needs long term efforts of the whole society, not only in production sectors but also in service and household sectors.     

Tourism and CO<Subscript>2</Subscript> emissions nexus in Southeast Asia: new evidence from panel estimation

The past decade has seen the rapid development of the tourist industry in Southeast Asia. There is increasing concern that tourism is highly affecting CO₂ emissions, but the nature of the relationship is still unclear. The main target of this paper is to investigate the existence of a linear and/or nonlinear relationship between tourism and CO₂ emissions in the five most important countries located in Southeast Asia, using the panel cointegration and pooled mean group techniques. The results indicate that tourism and CO₂ emissions are cointegrated, implying that tourism affects CO₂ emissions in the long run. Our findings support the nonlinear relationship between tourism and emissions as well as economic activities and CO₂ emissions. Accordingly, an inverted U-shaped relationship exists between tourism and emissions confirming the existence of an Environmental Kuznets Curve in the Southeast Asian tourism industry. Furthermore, the empirical results show that economic activities and energy consumption greatly increase emissions.     

中国碳排放库兹涅茨曲线实证研究——基于Gregory-Hansen协整分析

中国反复、多次出现大范围持续性雾霾天气使碳排放与经济增长问题成为理论界研究的热点,选取1978~2012年中国历年相关统计数据,采用Gregory-Hansen协整检验方法结合结构突变分析,实证检验我国碳排放与能源消费、经济增长及产业结构的关系。研究结果显示,中国碳排放环境库兹涅茨曲线为正U型,且该曲线存在结构突变;经济增长、能源消费、产业结构对碳排放都具有显著的增排效应。因此,建议在保证经济可持续的中高速增长前提下,通过提高能源利用效率、推进产业结构调整等措施来降低碳排放量,使"APEC蓝"能够成为一种"新常态"。     

Income inequality and CO2 emissions: nonlinear evidence from Turkey

The income inequality-economy link has been argued by researchers a long time. But the impact of income inequality on environmental pollution is a new investigation topic for developing countries. Turkey is well known as an emerging economy which has a high level of income inequality and CO₂ emissions. Therefore, this paper concentrates on the income inequality-CO₂ emissions link in Turkish economy by applying a nonlinear analysis. This paper integrates economic growth and financial development to the CO₂ emissions specification over the period of 1987–2019. We employ the nonlinear autoregressive distributed lag approach to explore the long-run nonlinear linkages between the series. Our findings reveal an asymmetric cointegration among variables. Positive and negative income inequality shocks positively affect CO₂ emissions implying that positive and negative shocks of income inequality enhance CO₂ emissions in the long run. Negative economic growth shocks decrease CO₂ emissions, while positive shocks to financial development increase CO₂ emissions in the long run. We provide important policy suggestions that might be useful to the policymakers to decrease CO₂ emissions in Turkey.

     

Energy–growth nexus revisited: an empirical application on transition countries

This study investigates the energy–growth nexus for transition countries analysing Granger causality between GDP growth per capita and energy use per capita. For this purpose, 17 countries located at Central and Eastern Europe and Caucasian region are chosen and a panel dataset consisting of these countries for the available period of 1990–2011 is studied. In the study, Granger causality is investigated using bootstrapped panel causality approach proposed by Konya (Econ Modell 23(6):978–992, 2006). The approach gives consistent results in case of cross-sectional dependency and heterogeneity of slope coefficients between countries. Causality is examined for two scenarios: one with a trend and one without a trend. The results reveal that, in general, there is no causality running between energy consumption and economic growth, yet there is causality running from energy consumption to economic growth for some countries and sign of the relationship is always negative. Therefore, increases in energy consumption harm economic growth.     

Impacts of economic growth and urbanization on CO<Subscript>2</Subscript> emissions: regional differences in China based on panel estimation

This study analyzed the impact of urbanization and the level of economic development on CO₂ emissions using the STIRPAT model and provincial panel data for China. This study classified the 29 provinces of China into three groups (eastern, central, and western regions) and examined regional differences in the environmental impacts of urbanization and economic development levels. The results demonstrated that there was an inverted U-shaped relationship between urbanization and CO₂ emissions in the central and western regions of China. However, we did not confirm the environmental Kuznets curve relationship between urbanization and CO₂ emissions in eastern China, where CO₂ emissions increase monotonically with urbanization. This study showed that the impacts of urbanization differ considerably. There was a U-shaped relationship between economic growth and CO₂ emissions. However, the point of inflexion was very low, which indicates that economic growth will promote CO₂ emissions in China. The share of the industry output value had a marginal incremental effect on CO₂ emissions. There was a decreasing effect of population scale on CO₂ emissions. Energy efficiency is the main factor that restrains CO₂ emissions, and the effect was higher in regions with low energy efficiency.     

我国减缓碳排放的近期形势与远期趋势分析

近3年来我国面临GDP能源强度呈上升趋势，能源消费及相应CO2排放增长对世界减缓碳排放的形势产生了更大影响的新的形势，从长远发展趋势看，我国当前由于工业特别是重化工业在国民经济结构中急剧增加引起的GDP能源强度阶跃性增长将随产业结构的稳定两平缓，并且随产业结构的优化和产业技术升级及高附加值产品比例提高而再度呈持续稳定下降的趋势。我国在现代化道路中与发达国家的历程相比，可以走更为节约能源和减少CO2排放的道路。但由于中国人口众多，和平发展的规模大、速度快，而且时间比发达国家滞后半个世纪以上，我国为实现现代化所必需的能源消费和CO2排放的增长会对全球的碳排放增长产生重大影响。这将使我国未来经济发展面临极为不利的外部环境。     

CO2 emissions in German, Swedish and Colombian manufacturing industries

This study evaluates and compares the trends in CO₂ emissions for the manufacturing industries of three countries: two developed countries (Germany and Sweden) that have applied several measures to promote a shift towards a low-carbon economy and one developing country (Colombia) that has shown substantial improvements in the reduction of CO₂ emissions. This analysis is conducted using panel data cointegration techniques to infer causality between CO₂ emissions, production factors and energy sources. The results indicate a trend of producing more output with less pollution. The trends for these countries’ CO₂ emissions depend on investment levels, energy sources and economic factors. Furthermore, the trends in CO₂ emissions indicate that there are emission level differences between the two developed countries and the developing country. Moreover, the study confirms that it is possible to achieve economic growth and sustainable development while reducing greenhouse gas emissions, as Germany and Sweden demonstrate. In the case of Colombia, it is important to encourage a reduction in CO₂ emissions through policies that combine technical and economic instruments and incentivise the application of new technologies that promote clean and environmentally friendly processes.     

Spatial and temporal variation of energy carbon emissions in Yantai from 2001 to 2011

In order to understand the characteristics of spatial and temporal variation, as well as provide effective ideas on carbon emissions and regulatory policy in Yantai, this article analyzed spatial and temporal variation of carbon emissions in Yantai based on energy consumption statistics for a variety of energy sorts together with industrial sectors from 2001 to 2011. The results were as following: First of all, Yantai’s carbon emissions grew by an average of 5.5% per year during the last 10 years, and there was a peak of 10.48 million carbon in the year of 2011. Second, compared with the gross domestic product (GDP) growth rate, the figures for energy carbon emissions growth rate were smaller; however the problem of carbon emissions were still more obvious. Furthermore, carbon emissions in Yantai increased rapidly before 2008; while after 2008, it increased more slowly and gradually become stable. Third, the energy consumption was different among regions in Yantai. For instance, the energy consumption in Longkou city was the largest, which occupied 50% of the total carbon emissions in Yantai; and the energy consumption in Chang Island was generally less than 1% of the Longkou consumption. Finally, there were relative close relationships among the spatial difference of carbon emissions, regional resources endowment, economic development, industrial structure, and energy efficiency.
