由于中国在碳减排方面肩负着越来越重要的责任，因此有必要从多尺度、多区域的角度进行系统评估，以审视特定区域的碳排放和不同类型的碳转移模式。通过识别国内31个省级行政区和国外184个国家/经济体之间的碳排放流向，基于国内和国际关系考察中国省/直辖市的国内外碳排放流向。总体来看，我国各省市按照碳排放流向分为4种模式，其中内陆省份主要从事国内碳排放转移，西部地区普遍接受碳排放，主要以东北和中部省份碳流出，沿海地区在平衡国内外碳排放盈余和赤字方面发挥着重要作用。对于中国不同次区域而言，认识碳排放转移关系有助于从远程连接的角度实现区域协同可持续发展。通过嵌套网络分析，以中国省市为重点的多尺度、多区域评估将现有研究延伸到国家和全球尺度，为中国区域可持续发展提供了坚实的基础。
Since China carries an increasingly significant responsibility in carbon emission reduction, a systematic assessment from the multi-scale and multi-regional perspective is essential to examine the region-specific carbon emissions and different kinds of carbon transfer patterns. By identifying carbon emission flows among 31 domestic provincial administrative regions and 184 foreign countries/economies, this work examines the domestic and foreign carbon emission flows of Chinese provinces/municipalities based on the intra- and inter-national relations. Overall, the provinces and municipalities in China are divided into 4 patterns according to carbon emission flows, among which inland provinces mainly engage in domestic carbon emission transfers, western regions generally receive carbon emissions with main carbon outflows in northeastern and central provinces, and coastal regions play an essential role in balancing carbon emission surpluses and deficits between domestic and foreign regions. For different sub-regions in China, recognizing carbon emission transfer relations contributes to the synergetic and sustainable regional development from a tele-connected perspective. With the nested network analysis, the multi-scale and multi-regional assessments focusing upon China’s provinces and municipalities extend the existing research to both national and global scales, providing a solid foundation for sustainable regional development in China.
