服务业碳排放日益受到世界各国的关注。然而，很少有研究探讨发展中国家服务业二氧化碳排放的驱动力。随着工业化进程加快，我国服务业特别是一些发达地区服务业面临着越来越大的节能减排压力。在本文中，为了更好地了解北京服务业二氧化碳排放的演变过程，我们利用子系统投入产出分解分析来研究北京服务业消费排放的格局和驱动因素。结果表明，交通运输业和科研技术服务业是北京市服务业中二氧化碳排放量最大的行业。排放强度效应可能使二氧化碳排放量减少 10,833 公吨，这主要是由于非服务业能源强度的降低。需求和技术的影响是北京服务业二氧化碳排放增加的主要原因。这种影响主要与服务业的外部成分有关，说明服务业对非服务业有较强的拉动作用。因此，服务业供应链脱碳、提高能源强度是缓解北京二氧化碳排放的必要措施。
The carbon emissions in service sectors have attracted increasing attention around the world. However, few studies have examined the driving forces for CO2emissions from service sectors in developing countries. With the process of accelerating industrialization, China’s service sectors are facing growing pressure to pursue energy savings and emission reductions, especially in several developed regions. In this paper, in order to better understand how CO2emissions in Beijing’s service sectors have evolved, we utilized a subsystem input–output decomposition analysis to study the pattern and driving factors of consumption-based emissions in Beijing’s service sectors. The results showed that the transportation sector and the Scientific Studies Technical Services sector caused the most CO2emissions in Beijing’s service sectors. The emission intensity effect potentially reduced CO2emissions by 10,833 Mt, primarily due to the decreased energy intensity of non-service sectors. Effects of demand and technology were mainly responsible for the increased CO2emissions in Beijing’s service sectors. Such influence was mainly related to the external component of service sectors, indicating a strong pull effect exerted by service sectors on non-service sectors. Thus, decarbonizing the supply chain of service sectors and improving the energy intensity are necessary to alleviate CO2emissions in Beijing.
