基金：国家社会科学基金重点项目“‘双碳’目标下环境污染与碳排放协同治理效应与机制创新研究”(22AGL029)。

减污降碳协同增效对未来实现我国“双碳”目标至关重要。目前已有大量研究围绕重点行业开展减污降碳协同效应评估,但从应急管理视角看,量化实证分析减污降碳协同效应差异的研究仍不多见。基于中国大陆31个省(市、区)2019年1月1日至2020年12月31日的CO₂排放量及空气质量日度数据,实证分析不同应急响应的减污降碳协同效应及其异质性,并从能源、工业、交通运输规模减排三个方面考察其内在机制。结果显示:①随着应急响应等级的提高,CO₂、PM_2.5减排效应增强,O₃总体未表现出下降效应。除三级及以下响应外,一级、二级响应状态下CO₂与PM_2.5均处于高协同水平,但不同响应状态下CO₂与O₃总体处于低协同水平。②异质性上,一级、二级响应状态下,CO₂和PM_2.5协同减排效应在南方地区、高交通密度省份、疫情严重区域相对较高,CO₂和O₃协同减排效应则仅在PM_2.5与O₃强正相关的特定省份较为显著。③内在机制上,一级响应通过显著降低能源、工业和交通运输规模实现CO₂和PM_2.5协同减排,二级、三级及以下响应状态下规模减排效应有所收窄,甚至出现反弹。基于上述结论,提出分月份、分地区、分污染物的减污降碳协同增效路径,可为探索应对气候变化和大气污染防治的“双赢”战略提供决策参考。"/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});$(document).ready(function(){window.metaData = {"journal":{"issn":"1000-5072","qiKanMingCheng_CN":"暨南学报（哲学社会科学版）","id":2,"qiKanMingCheng_EN":"Jinan Journal"},"fundList_cn":["国家社会科学基金重点项目“‘双碳’目标下环境污染与碳排放协同治理效应与机制创新研究”(22AGL029)。"],"article":{"keywordList_cn":["二氧化碳","减污降碳","空气质量","协同效应","应急响应"],"juan":"45","zhaiyao_cn":"减污降碳协同增效对未来实现我国“双碳”目标至关重要。目前已有大量研究围绕重点行业开展减污降碳协同效应评估,但从应急管理视角看,量化实证分析减污降碳协同效应差异的研究仍不多见。基于中国大陆31个省(市、区)2019年1月1日至2020年12月31日的CO2排放量及空气质量日度数据,实证分析不同应急响应的减污降碳协同效应及其异质性,并从能源、工业、交通运输规模减排三个方面考察其内在机制。结果显示:①随着应急响应等级的提高,CO2、PM2.5减排效应增强,O3总体未表现出下降效应。除三级及以下响应外,一级、二级响应状态下CO2与PM2.5均处于高协同水平,但不同响应状态下CO2与O3总体处于低协同水平。②异质性上,一级、二级响应状态下,CO2和PM2.5协同减排效应在南方地区、高交通密度省份、疫情严重区域相对较高,CO2和O3协同减排效应则仅在PM2.5与O3强正相关的特定省份较为显著。③内在机制上,一级响应通过显著降低能源、工业和交通运输规模实现CO2和PM2.5协同减排,二级、三级及以下响应状态下规模减排效应有所收窄,甚至出现反弹。基于上述结论,提出分月份、分地区、分污染物的减污降碳协同增效路径,可为探索应对气候变化和大气污染防治的“双赢”战略提供决策参考。","endNoteUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/article/getTxtFile.do?fileType=EndNote&id=6070","bibtexUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/article/getTxtFile.do?fileType=BibTeX&id=6070","abstractUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/10.11778/j.jnxb.20221742","qi":"1","id":6070,"nian":2023,"bianHao":"2023-1-92","zuoZheEn_L":"LI Hongxia, ZHENG Shiming, ZOU Ke","juanUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/Y2023","shouCiFaBuRiQi":"2023-03-17","qiShiYe":"92","qiUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/Y2023/V45/I1","lanMu_cn":"公共管理","pdfSize":"2084","zuoZhe_CN":"李红霞, 郑石明, 邹克","risUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/article/getTxtFile.do?fileType=Ris&id=6070","title_cn":"应急响应的减污降碳协同效应:内在机制与增效路径","doi":"10.11778/j.jnxb.20221742","jieShuYe":"107","keywordList_en":["air quality","carbon dioxide","emergency response","pollution and carbon reduction","synergistic effect"],"endNoteUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/article/getTxtFile.do?fileType=EndNote&id=6070","zhaiyao_en":"Improving the synergistic reduction effect of air quality and carbon emission is crucial to realizing China's “dual carbon” goal in the future. At the present, a large number of studies have been conducted to evaluate the synergistic reduction effect of air quality and carbon emission in key industries, but empirical studies on the synergistic effects from the perspective of emergency management are still rare. By collecting the daily data of CO2 emissions and air quality in 31 provinces in China from January 1, 2019 to December 31, 2020, we empirically analyze the impact of emergency response on the co-benefits and its spatial heterogeneity. Then we further investigate its internal mechanism from three aspects of industry, energy, and transportation scale. The results show that: 1) With the upgrade of emergency response level, the reduction effect of CO2 and PM2.5 is enhanced, but the reduction effect of O3 is not significant; 2) In terms of heterogeneity, under the level I and II emergency response, the synergistic reduction effect of CO2 and PM2.5 is relatively high in southern regions, high traffic density provinces, and areas with severe pandemics, and the synergistic reduction effect of CO2 and O3 is only significantly high in specific areas where PM2.5 and O3 are strongly positively correlated; 3) The synergistic reduction effect of CO2 and PM2.5 is significant through reducing the scale of energy, industry, and transportation under the level I emergency response, while the scale reduction decreases or even rebounds under the level II and level III emergency response. Based on the above conclusions, the synergistic paths for improving the co-benefits of air pollution and carbon emission control by month, region, and pollutant are put forward, which can provide decision-making references for exploring “win-win” strategies of climate change and pollution control.","bibtexUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/article/getTxtFile.do?fileType=BibTeX&id=6070","abstractUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/10.11778/j.jnxb.20221742","zuoZheCn_L":"李红霞, 郑石明, 邹克","juanUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/Y2023","lanMu_en":"","qiUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/Y2023/V45/I1","zuoZhe_EN":"LI Hongxia, ZHENG Shiming, ZOU Ke","risUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/article/getTxtFile.do?fileType=Ris&id=6070","title_en":"The Synergistic Reduction Effect of Air Quality and Carbon Emission in Pandemic Emergency Response: Internal Mechanism and Improving Path","hasPdf":"true"},"authorNotes_cn":["李红霞,华南理工大学公共管理学院;郑石明,暨南大学公共管理学院/应急管理学院/公共政策研究院;邹克,广东金融学院。"]};if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
