基于 EIO-LCA 模型的中国 1992-2012 年碳排放结构特征研究

This paper constructs a non-competition input-output table, calculates the carbon emission data in China from 1992 to 2012, and analyzes the structural characteristics of its emissions using the EIO-LCA method. The results show that, in general, China's carbon emission shows a fast rising trend. From the view of department structure, in 1992-2012, the main reason for the growth of carbon emissions in China was the large increase in investment activities, exports and the consumption of urban residents. Investment activities accounted for 55.83% of the total increment of the final demand, and the embodied emissions were mainly in the sector 28 (Construction). Exports accounted for 24.38% of the total final demand. The embodied emissions were mainly concentrated in the manufacturing industry. In general, China's exports contain higher carbon emissions. The consumption of urban residents accounted for 14.99% of the total increment of the final demand. The embodied emissions were mainly concentrated in sector 25 (Production and distribution of electric power and heat power). In 1992-2012, the growth rate of sector 28, 17 (Manufacture of general and special purpose machinery) and 35 (Other services) was the most obvious, and the three accounted for 60.45% of the total increment. In addition, the carbon emissions of sector 22 (Other manufacturing), 2 (Mining and washing of coal), 5 (Mining and processing of nonmetal ores), 3 (Extraction of petroleum and natural gas) and 8 (Manufacture of textiles) maintained a downward trend.
