Abstract:

Using input-output model of vertical specialized method and improved input-output model, this paper analyzes the total and industrial embodied CO2, embodied CO2 of imported intermediate products and its structural change in China-Japan trade, which are compared with the results of improved input-output method. The results show that China is a net exporter of embodied CO2, and there is imbalance between the responsibility of carbon reduction and profit in China. There is a gap in imported embodied CO2 from Japan by China calculated by two kinds of methods, which mainly lies in the part generated by processing and re-exporting imported goods. The adaptability of the two methods is discussed, and the input-output method under vertical specialization can reflect the embodied CO2 produced by Chinese processing trade better. At the same time, processing imported goods gradually changes structural emissions of embodied CO2, which is mainly focused on the capital-intensive industries and primary products industries, such as the metal rolling, coke, refined oil and nuclear fuel industry. But technology-intensive industries, such as the electrical and optical equipment industries, are mainly processing goods on order.
