为了测算中国近年来进出口贸易中的内涵能源及排放,采用投入产出方法,利用中国2002年、2005年和2007年投入产出表,计算2002年和2005年以及2006年和2007年出口产品的内涵能源和内涵CO2排放。研究结果显示:进出口加工贸易对于核算中国进出口内涵能源及CO2排放有重要影响;中国出口产品内涵能源(以C当量计)由2002年的2.09亿t增加到2005年的5.91亿t,占全国能源消费总量的比重由13.11%增长到25.04%;同时中国进口产品内涵能源也呈增长趋势,净出口的内涵能源2007年达到2.61亿t,占全年能源消耗总量的9.30%。中国依然是净出口内涵能源大国。
In order to measure the energy and emissions in China’s import and export trade in recent years, using the input-output method, using the input-output tables of China in 2002, 2005 and 2007 to calculate the export products in 2002, 2005, 2006 and 2007 Connotation of energy and content of CO2 emissions. The results show that the import and export processing trade has an important impact on accounting for the energy consumption and CO2 emissions of China’s import and export. The energy content of China’s export products (in terms of C equivalent) increased from 209 million t in 2002 to 591 million t in 2005, accounting for The share of total energy consumption increased from 13.11% to 25.04%. At the same time, the connotative energy content of China’s imported products also showed an increasing trend. The net energy content of net exports reached 261 million t in 2007, accounting for 9.30% of the total annual energy consumption. China is still a major energy exporter with a net export.
