大气污染的区域间溢出可以看作是经济外部性和长距离传输的混合物。为全面揭示这一问题，引入源-受体关系模型（SRR），综合排放区（生产区）向受体区的物理迁移和驱动区（消费区）向排放区的虚拟转移对2010年中国30个省级区域二氧化硫排放的溢出效应，编制了基于消费的二氧化硫排放清单。将最终区域需求引起的排放量与中国七个地区收到的排放量进行比较，南方（0.59 Mt），北方（0.25 Mt），西北（0.18 Mt），东部（0.14 Mt）地区大量外包SO2污染，而中部2010年，东北部（-0.66 Mt）、东北部（-0.42 Mt）和西南部（-0.08 Mt）地区承受了过重的环境负担。重庆、上海、北京和天津四个直辖市以及最富裕的广东省在对它们在驱动者、排放者和接受者中的作用进行全面评估后，显示出显著的污染转移。山西、内蒙古、贵州、河南和山东的SO2排放控制对减缓气候变化的协同效益最大。研究发现，日本在中国出口中所占的SO2沉降份额大于其市场份额，而中国的其他主要贸易伙伴则不然。北京作为一个特大型城市，在电力、煤炭、化工、食品、石油加工和炼焦等行业的电力需求、食品消费、杂项服务和蓬勃的研究活动中产生了大量的SO2排放，但其中86%的排放是由北京外包的。总的来说，北京引起的二氧化硫排放溢出估计为20万吨，是其作为整个供应链受体的份额的76倍。本研究为中外大气污染联防联控战略规划提供了一个分析框架。研究结果有助于减少污染转移、合理征税、有效控制排放者、合理补偿受纳者。
Inter-regional spillover of air pollution can be regarded as a mixture of economic externalities and long-distance transport. To comprehensively reveal this problem, a new consumption-based sulfur dioxide (SO2) emission inventory in 2010 for 30 provincial regions of China was compiled by introducing source-receptor relationship (SRR) model to integrate the spillover impacts of physical transport from the emitter (producer) region to the receptor region and virtual transfer from the driver (consumer) region to the emitter region. Compared the emissions induced by final regional demand with the emissions received in seven regions of China, Southern (0.59 Mt), Northern (0.25 Mt), Northwestern (0.18 Mt), and Eastern (0.14 Mt) areas outsourced SO2pollution in the mass, whereas Central (−0.66 Mt), Northeastern (−0.42 Mt), and Southwestern (−0.08 Mt) areas took excessive environmental burdens in 2010. The four municipalities, Chongqing, Shanghai, Beijing, and Tianjin as well as the most affluent province Guangdong showed significant pollution transfer after an overall assessment of their roles in drivers, emitters and receptors. Shanxi, Inner Mongolia, Guizhou, Henan, and Shandong showed the largest co-benefits of SO2emissions control for climate change mitigation. Japan was found to receive more portions of transboundary SO2deposition than its market shares in China's export instead of other major trade partners of China. As a mega-city, Beijing induced significant SO2emissions for power requirement, food consumption, miscellaneous services, and her vibrant research activities through the sectors of the power industry, coal mining, chemical manufacturing, food-related industries, petroleum processing and coking, but 86% of those emissions were outsourced by Beijing. In total, the spillover of SO2emissions induced by Beijing was estimated at 0.20 Mt, 76 times more than its own share as a receptor across the supply chains. This study is competent for an analytic framework of strategic planning for joint prevention and control of air pollution in China and other countries. The results can help reduce pollution transfer, properly tax on drivers, effectively control the emitters, and reasonably compensate the receptors.
