Analysis of interprovincial trade embodied carbon emissions in Beijing-Tianjin-Hebei and surrounding provinces: based on constructed MRIO Model

The interprovincial trade embodied carbon emissions plays an important role in the national emission reduction target among China's provinces. Furthermore, it will affect the smooth start-up of the national carbon trade market as well as the implementation of targets in 2030 for dealing with the climate change. Based on constructed MRIO model, this paper analyzes the embodied carbon emission trade flows among Beijing, Tianjin, Hebei and surrounding regions such as Shanxi, Shaanxi, and Inner Mongolia. The results indicate that six provinces have formed different patterns of carbon trade balance, where Beijing, Tianjin, and Hebei provinces are in a deficit position, while the other three provinces are in a surplus position.Beijing, Tianjin, and Hebei have transferred part of the carbon emissions to the other three provinces, which shows greater heterogeneity among various provinces and provincial different sectors. On basis of the conclusions, this paper puts forward some suggestions on provincial decomposition, responsibility distribution, and provincial collaborative reduction for national emission reduction targets.

Sources and Flows of Embodied CO_2 Emissions in Import and Export Trade of China

This paper uses the Global Trade Analysis Project(version 7)database to calculate embodied CO2emissions in bilateral trade between China and other countries(regions)based on input-output methods.The sources and flows of embodied CO2emissions in import and export trade of China are analyzed.Results show that the flows of embodied CO2emissions in export trade are highly concentrated.The main flows to the United States(US)and Japan account for 1/4 and 1/7 of the total CO2emissions in export trade,respectively.Concentrated flows of total exports and small differences in export structure are the main reasons for the highly concentrated export trade.The sources of embodied CO2emissions in import trade have relatively low concentration.Taiwan Province of China,Hong Kong Special Administrative Region of China,US,Russia,Republic of Korea,and Japan account for around 7.72%–12.67%of the total embodied CO2emissions in import trade.The relative dispersion of import sources,the impact of the import structure,and the level of production technology in importing countries caused low concentration of CO2emissions in import trade.Overall,the embodied CO2emissions in the export trade of China are higher than those in import trade.As a result,production-based CO2emissions are higher than consumption-based CO2emissions.The difference of 8.96×108t of CO2,which comes mainly from the US,Japan,Germany,and the United Kingdom,accounts for 58.70%of the total difference.Some suggestions,such as improving energy efficiency,alerting high carbon-intensive industries transfer,expanding the market for sharing risks,and prompting the accounting system of consumption-based CO2emissions,are proposed based on the results.

Carbon Emissions Embodied in China’s International Trade of Textiles and Clothing

International trade of textiles and clothing has numerous environmental implications, such as carbon leakage. In order to estimate the CO2 emissions embodied in China's imports and exports of textiles and clothing, an empirical analysis was carried out with environmental input-output analysis (EIOA) method using the most recent data available. The results indicate that China is a net exporter of embodied CO2 emissions on account of its international trade of textiles and clothing. The amount of the net exported embodied CO2 emissions increases from 110 million metric tons(Mt) of CO2 in 2002 to 280 Mt of CO2 in 2011. In particular, United States, Japan, and European Union transfer to China 339 Mt of CO2, 291 Mt of CO2 and 396 Mt of CO2 respectively during the period of 2002 -2011.

CO_2 Emissions Embodied in China-U.S.Trade

After the Kyoto Protocol was implemented,carbon leakage exerts great influences on international trade and economy.Trade creates a mechanism for consumers to shift environmental pollution associated with their consumption to other countries.China has overtaken the U.S.as the world's biggest CO2 emitter since 2006.As China's second largest trade partner,the U.S.has the biggest trade deficit with China which has aroused a lot of disputes between the two parties.But so far the assessments of the trade imbalance of China-U.S.have paid little attention to environmental impacts associated with the trade imbalance.Applied an input-output approach,the article estimates the amount of CO2 embodied in China-U.S.trade during 1997-2007.It was found that through trade with China,the U.S.reduced its CO2 emissions compared with a non-trade scenario.Due to the greater carbon-intensity and relatively less efficient production processes of Chinese industry,China-U.S.trade resulted in more CO2 emissions in China and the world.In the end,the article gives some suggestions:it is equal and sustainable that the international accounting methodologies should be improved,for CO2 emissions responsibility must be designed to account for the dynamic nature of international trade.

Accounting and Responsibility Allocation on Carbon Emissions Embodied in International Trade

This paper calculated the scale of carbon emissions embodied in the import and export of the world＇s major countries based on input-output principles and international trade data, as well as data on various countries＇carbon emissions in 2005 from domestic consumption and emissions embodied in trade. The results illustrate that, because of international trade, consumers in developed countries should bear the responsibility for a large portion of CO2 emissions. The researchers separated the net transfer balance of embodied emissions in international trade according to four different effects： size effect, exchange rate effect, structural effect, and pure technical effect, all of which favor the sharing of responsibilities between producers and consumers.

Estimation of the embodied carbon in China's wood products trade using input–output methodology

This study calculates the embodied carbon in imports,exports,net exports,and the processing trade of China's wood product sector between 2001 and 2016 using a non-competitive input-output(I-O)model.The results demonstrate that embodied carbon showed a decreasing trend between 2001 and 2016.Embodied carbon was lowest in wood furniture imports and highest in paper and paperboard imports.The embodied carbon in sawnwood and veneer sheet exports was the lowest and paper and paperboard exports was the highest.The embodied carbon in the processing trade of paper and paperboard was the highest.To reduce the embodied carbon in China's wood products,the government should promote technological transformation and upgrading and encourage the implementation of green technology innovation.

Embodied Pollution in China-U.S.Trade——An Empirical Study Based on Estimation of Input-Output Technology Matrix

Using input-output tables of China and the U.S., this paper has calculated the pollution embodied in trade and structure of pollution, the balance of emissions embodied in trade （BEET） and the pollution terms of trade （PTT） for 18 manufacturing sectors of China and the US. between 2001 and 2010. The calculation aims to verify whether China has become a ＂pollution haven＂ in bilateral trade with developed countries represented by the U.S., and whether Chinese exports are ＂dirtier＂ compared with imports from the U.S., and further conducting an industry structure analysis and effect decomposition study on pollution embodied in trade in industrial goods between China and U.S.. Result of our research indicates that according to our calculation of the BEET, China remains a country with environmental deficits in bilateral trade with the U.S. while the gaps between pollution embodied in China＇s export and import are narrowing. Pollution embodied in China＇s export has the tendency of increase before decline while pollution embodied in import demonstrates no significant tendency of decline. Through effect decomposition, we further found that the effect of technology arising from the substantial decline of pollution intensity effectively lowered pollution embodied in export and narrowed the environmental deficits of China in its bilateral trade. The effect of scale arising from growing export volumes significantly increased China＇s environmental deficits while the structural effect arising from changes in the structure of import and export is insignificant in reducing environmental deficits. Our calculation of the PTT led to the finding that China＇s export goods are more pollution intensive compared with import goods and that the structure of US exports to China is cleaner than the structure of Chinese exports to the US., which requires further improvements of China＇s import and export structure.

The energy-intensity of China's export trade

China is one of the world’s major importers and exporters. On the one hand, massive exports have created enormous economic value and employment opportunities for Chinese and become one of the vital forces underpinning the country’s economic growth. On the other hand, exports have caused a huge amount of energy resource consumption and carbon emissions and added pressure to the country for a sustainable growth. China exports a wide variety of products, each of which is attached to a different industry chain with different energy consumptions. Therefore, the evolution of the product structure has become one of the key factors affecting China’s future energy consumption and economic growth. To further promote nationwide energy conservation and emission reduction, reduce the pressure exerted by economic growth on energy consumption and the environment and win more space for sustainable economic growth, it is imperative to understand energy consumption and carbon emissions embodied in export products and provide support for China’s export policy adjustment. This study attempts to calculate, compare and analyze the embodied energy and carbon emissions in 46 major export products using the full life cycle assessment method, and concludes by offering policy recommendations.

MRIO model-based study on water nitrogen pollution transfer embodied in international trade

This study uses the global pollutant emission databases and global input-output model in 2015 to calculate the impact of international trade on global water nitrogen emission patterns,based on considering the total amount of pollutant transfer and pollutant emission intensity of trade flows The main conclusions are as follows:(1) There are always a large amount of water nitrogen emissions transferring from developed economies to developing economies embodied in their bilateral trade activities.Small amount of transfers are of some areas with similar endowments of agricultural resources or long distances.(2) In 2015,the net import of water nitrogen pollution embodied in China's trade was 160,000 tons,accounting for 2.72% of the global water nitrogen imports.The sharp increases in cereal imports,together with high food storage as well as high pollution intensity embedded in trade are the main reason.It is recommended that through applying alleviations such as agricultural machinery assistance and technical training to accelerate the transfer and spread of agricultural technology in Africa,Asia,and other regions,thus helping increase agricultural production productivity in underdeveloped areas and reducing the pollution intensity embodied in trade flows from underdeveloped areas to developed areas.

Research on carbon emissions embodied in China-Russia trade under the background of the Belt and Road

Based on the latest China-Russia input-output data sets over the period from 2007 to 2015,this study quantified the flow of embodied carbon emissions in China-Russia trade using the emission embodied in bilateral trade(EEBT)approach.In addition,the structural decomposition analysis(SDA)was employed to identify the potential driving factors that affect embodied carbon in imports and exports.The results showed as follow.1)China was a net exporter of carbon emissions in bilateral trade between China and Russia during 2007–2015.Despite that the bilateral trade scale had expanded considerably,the net export volume of CO_(2)from China to Russia decreased from 13.21 Mt in 2007 to 4.45 Mt in 2015.2)From the perspective of different sectors,the metal manufacturing and the chemical sectors of China and Russia were the main sources of CO_(2)emissions.3)In terms of driving factors,it was found that the carbon emission coefficient was the main reason for contributing to embodied emission reduction.Moreover,the contribution rate of carbon emission coefficient to reduce the carbon emissions in imports reached to 95.26%,as well as 108.22%in exports.The bilateral trade scale was the main driver for the increase in embodied carbon emissions,and the contribution rate to embodied carbon emissions in imports and exports were 14.80%and 65.17%,respectively.4)This study argued that China and Russia should further optimize the energy structure and improve the energy efficiency and intermediate technology in the future.

中国农产品出口贸易隐含碳排放测算及异质性分析——来自“一带一路”沿线国家(地区)的证据

采用环境拓展投入产出法测算了2007—2021年中国对“一带一路”沿线国家(地区)农产品出口贸易的隐含碳排放,进而运用LMDI模型探究贸易规模因素、出口结构因素和农业技术因素对隐含碳排放变动的贡献值与贡献率,从农产品部门和贸易区域两个层面对隐含碳排放变动的驱动因素进行异质性分析。研究发现:第一,2007—2021年中国对“一带一路”沿线国家(地区)的出口贸易隐含碳排放整体呈上升趋势,农产品出口贸易隐含碳排放年均增长率超过农产品出口贸易额年均增长率2.75%,隐含碳排放效率下降。第二,农产品出口贸易隐含碳排放存在明显的部门差异,因不合理的出口结构,农业、食品制造业和食品加工业等中高度碳排放密集型部门对隐含碳排放总量变动的贡献值占比较大,而林业、畜牧业等低度碳排放密集型部门的这一占比较小。第三,农产品出口贸易隐含碳排放存在明显的区域差异,对东南亚国家(地区)出口农产品产生的隐含碳排放占总碳排放的60%以上,贸易规模因素和农业技术因素是造成区域差异的主导因素。上述发现揭示了中国农产品出口贸易隐含碳排放变动的原因,为优化农产品出口结构、调整农产品出口贸易策略及碳排放双控制度的实施提供了新的思路与经验证据。

基于多区域投入产出的黄河流域贸易隐含碳排放时空格局及结构分解

厘清黄河流域贸易隐含碳排放时空格局及其驱动因素,对于制定公平有效的减排方案,实现区域合作减排的重要目标至关重要。利用多区域投入产出模型深入研究2007—2017年黄河流域9个省区贸易隐含碳排放的构成,以及其在省级和行业层面的转移路径;通过结构分解方法,追踪黄河流域贸易隐含碳排放区域内外的影响因素,揭示其区域内外影响因素的异质性。结果表明:黄河流域整体呈净贸易隐含碳转出区域,主要由中间投入的贸易方式进入其他各省的生产需求时导致。该流域的生产供应和整体需求正向中西部和东北地区转移,而对东南沿海省份的供应和需求正逐渐减少。区域外的最终需求和本地的碳排放强度是影响转出贸易隐含碳的主要因素,区域内的最终需求和区域外的碳排放强度是影响转入贸易隐含碳的主要因素。此外,生产结构和最终需求是影响黄河流域贸易隐含碳排放的关键因素,前者对黄河流域贸易隐含碳排放起抑制作用,后者则主要起驱动作用。

国际贸易隐含碳转移溢出、转型风险与宏观金融稳定

在国际贸易、环境经济与气候金融相互影响的背景下,本文通过构建可以观察碳转移溢出效应的全球碳转移联通网络,实证分析了碳转移溢出对宏观金融稳定的影响及传导机制。结果表明:各经济体之间碳转移溢出明显降低了经济发展水平较低、气候损失较大以及气候表现绩效较差经济体的金融稳定水平,特别是增加了经济体的外债清偿风险、经常账户余额风险和国际储备流动性风险,资产价格重估视角下的转型风险是其中介机制。此外,本文还发现气候适应性措施能够有效减缓碳转移溢出对宏观金融稳定的影响,相比之下,现有的绿色宏观审慎监管框架需要进一步完善。本文探讨了气候金融框架下气候变化影响宏观金融稳定的一个可能传导链条,为从双循环视角推进我国经济绿色发展提供了新的证据。

中国省际贸易隐含PM_(2.5)排放转移及其环境公平性研究

本文首先基于多区域投入产出模型,结合能源驱动的PM_(2.5)排放清单,构建了2017年中国环境拓展的多区域投入产出表。而后,以生产侧与消费侧的双视角测算了2017年我国30个省份贸易中隐含PM_(2.5)排放与增加值的转移特征,并基于排放与增加值的净转移矩阵借助区域环境不公平指数对省际贸易中PM_(2.5)污染排放与经济利益交换的公平性进行测度。结果表明,省际贸易中隐含PM_(2.5)与隐含增加值的转移流向相反,中部与东北等相对欠发达地区是隐含PM_(2.5)的主要流入地,而沿海地区发达省份是隐含增加值的主要流入地。发达省份通过省际贸易既可一定程度上避免PM_(2.5)污染也可获得来自外省(区、市)的经济利益,具有环境与经济的双优势,而部分欠发达省份则是环境与经济双失。区域环境不公平指数的测度结果表明,发达省份与欠发达省份之间存在明显的差值,欠发达地区在省际贸易中面临相对明显的环境不公平挑战。最后,建立了省际贸易污染补偿机制与方案以缓解环境不公平性。

Estimation of China'S Embodied CO_2 Emissions during 2000-2009

The problem of CO2 embodied in international trade has attracted increasing attention in China. To analyze this issue, the present paper directly calculates emission factors for 15 industries in 2002, 2005 and2007. We then examine a consumption-based system and a single-region input-output model to estimate China＇s embodied emissions during 2000- 2009. Our results show that, when a consumption-based system is adopted, China＇s emissions are lower than those reported by some international organizations. The rapid growth in China ＇s exports＇ is a key determinant of China＇s rising total emissions. All countries shouM strengthen their cooperation in improving their current greenhouse gas inventories. Furthermore, China needs to encourage trade in low-carbon products and technology.

中国省际贸易隐含碳及其城乡流通格局分析

开展省际贸易隐含碳流通研究,有助于揭示区级贸易的异地环境影响,识别并划分碳减排责任,对于区域协同减排、公平发展具有重要理论和实践意义。基于2017年中国区域间投入产出表及各省(区、市)能源消费数据,利用环境拓展的投入产出模型,在分析省际贸易隐含碳流通格局的基础上,进一步揭示城乡贸易隐含碳的空间格局和流通路径。研究表明:①贸易隐含碳的输入和输出具有较大的省际差异,净输入区域主要包括华东和西南地区,净输出区域主要集中在华北、东北和西北地区;②贸易隐含碳排放主要从第二产业发达或能源资源富集的经济欠发达地区向经济发达地区流动;③省际贸易隐含碳流通路径相对集中,城镇间贸易隐含碳流通格局与省际的基本一致,而农村间隐含碳贸易体量较小,碳排放路径较为分散;④从全国尺度看,城镇是贸易隐含碳输入的热点区域,而农村则是碳输出的主要源区。各省(区、市)农村输入城镇的贸易隐含碳量明显大于城镇输入农村的贸易隐含碳量,这表明农村在城乡贸易中承担了较大的碳排放压力,建议未来应进一步优化区域生产布局、提升贸易流通效率,并基于区域隐含碳开展省域及城乡之间的横向碳补偿,推动区域之间的协同减排和城乡公平发展。

全球价值链视角下的出口贸易隐含碳研究

从全球价值链视角研究碳减排,可以为中国“碳双减”提供政策启示。采用1995—2009年的跨国跨行业面板数据,结合规模效应、结构效应和技术效应,分析全球价值链嵌入位置对出口贸易隐含碳的影响。研究结果显示,产出上游度和投入下游度的上升均会导致出口贸易隐含碳水平升高,这说明如果一国以矿业、制造业为主要产业嵌入全球价值链分工体系,那么出口贸易隐含碳水平会升高,稳健性检验结果强化了这一结论。此外,对于污染密集型行业,全球价值链效应会更弱,但是对于劳动密集型行业,全球价值链效应会更加明显。因此,为了在2030年实现碳达峰目标,中国政府应当优化产业布局,通过约束污染密集型行业和劳动密集型行业出口,调整出口规模和改善出口贸易结构。

粮食贸易对中国隐含碳排放的影响研究

粮食系统是温室气体排放的主要来源之一。中国作为世界第一碳排放国以及世界粮食生产和贸易大国,在碳减排压力下探索粮食贸易对碳排放的影响具有重要现实意义。本文通过生命周期评估法测算1998-2020年中国粮食双边贸易隐含碳排放量,同时运用面板自回归分布滞后模型(ARDL)分析中国粮食双边贸易量对隐含碳排放的长期、短期影响。结果表明,2003年之后中国一直是粮食隐含碳排放净进口国,且中国粮食隐含碳排放净进口主要来源国为巴西、美国、阿根廷等。粮食进口贸易和出口贸易长期和隐含碳排放均呈倒U形关系。中国应在保证粮食安全的前提下适当增加粮食贸易的同时优化进口来源国结构,尽量选择从巴西和美国等经济发达国家进口粮食。

贸易协定环境条款深度与贸易隐含碳

本文基于贸易协定规则文本,测度不同国家对之间贸易协定环境条款深度,并结合2000—2018年64个国家矩阵50个细分行业的贸易隐含碳数据,实证探究贸易协定环境条款深度对贸易隐含碳的影响。研究发现,提升贸易协定环境条款深度能够显著降低贸易隐含碳,国家间绿色技术合作、国家内部环境治理能力和碳生产率发挥了重要传导机制。异质性分析表明,不同种类贸易协定环境条款的作用效果具有显著差异,与碳排放相关度较高的条款、贸易联系紧密度较高的国家组合、蕴含在出口产品中的国外碳排放,在提升贸易协定环境条款深度时对贸易隐含碳的削减效果更强;贸易协定环境条款深度提升对减少非技术密集型行业和高碳排放密集度行业贸易隐含碳的效果更加显著。
