二氧化碳低排放是实现绿色中国可持续发展的基础。近年来，我国首都北京严重的环境污染--气候异常、严重雾霾和人类亚健康问题日益受到重视。本文采用投入产出分析方法，对2000 - 2010年北京市工业部门能源相关CO2排放进行了分析。计算了北京市各行业的直接、间接和总CO2排放量。此外，还从技术、部门关联、经济结构和经济规模等角度对影响区域经济发展的驱动因素进行了结构分解分析。结果表明：2007-2010年，北京市各部门CO2排放量增长率急剧上升，2007-2010年略有下降。金属和非金属采矿业、电力、天然气和供水部门以及建筑业造成的二氧化碳排放量最多。经济结构的变化和经济的快速增长导致北京市CO2排放量增长显著。因此，优化经济结构和提高技术水平是缓解CO2排放的重要途径。虽然目前我们可以适当利用化石燃料，但要减少CO2排放，还需要进一步研究新能源和清洁发展，以及加强政府管理力度。
Low carbon dioxide (CO2) emissions are the foundation on which to realize the sustainable development of a green China. Recently in Beijing, the capital of China, serious environmental pollution-climate anomaly, severe haze and human sub-health have been accorded more importance. This study examines the energy-related CO2emissions generated by Beijing industries from 2000 to 2010 by using an input–output analysis method. The direct, indirect and total CO2emissions of sectors in Beijing were calculated. In addition, structural decomposition analysis (SDA) was conducted to evaluate the driving factors from the perspective of technology, sectoral connection, economic structure and economic scale. The results show that the growth rate of sectoral CO2emissions in Beijing has drastically increased during this time with a moderate decline during 2007–2010. The metal and non-metal mining industries, the electric power, gas and water supply sector and the construction industry caused the most CO2emissions. The economic structure change and the rapid economic growth led to the significant increase in CO2emissions growth in Beijing. Thus, optimizing the economic structure and improving the technology are important to alleviate CO2emissions. Although we can currently appropriately utilize fossil fuels, further research on new energy and clean development, as well as enhanced government management strength is required to reduce CO2emissions.
