Study on the Impact of the Export of China’s Final Use Products on Domestic SO2 Emissions

Abstract

Since China’s accession to the World Trade Organization (WTO), its export volume has achieved rapid growth. Meanwhile, the manufacturing of export products has also resulted in a large amount of SO2 emissions in China. To explore the relationship between the export of China’s final use products (ECFuP) and SO2 emissions, this paper first used the Multi-Regional Input–output (MRIO) model to study the SO2 emissions caused by ECFuP during 2003–2011. Then, this paper uses Structural Decomposition Analysis (SDA) to decompose the factors affecting SO2 emission into technical effect, structural effect and scale effect. The results showed that (1) the amounts of China’s SO2 emissions caused by the ECFuP have increased (2003–2007), declined (2007–2009), and increased again (2009–2011). (2) Scale effect is the main factor that causes the increase of SO2 emissions in China; technical effect mainly resulted in a decrease of emissions, whereas structural effect has less impact. Specifically, from 2003 to 2011, scale effect increased domestic SO2 emissions by 2.2 million tons; technical effect and structural effect reduced by 2.4 million tons and 0.5 million tons of emissions, respectively. (3) For different regions, there is a positive correlation between the consumption of the ECFuP and China’s SO2 emissions. Among them, NAFTA (accounting for 33.77%) leads to the largest SO2 emissions, and OTHER EU (5.79%) is the least. (4) From the industrial aspect, some industries with relatively small ECFuP have caused high SO2 emissions. The specific performance is as follows, among the 17 industries, Electricity, Gas and Water Supply (EGW) only occupied 0.6% of the total ECFuP, but it has the largest SO2 emissions (55%); in contrast, while Electrical and Optical Equipment (EOE) occupied 42% of the total ECFuP, its SO2 emissions only accounted for 0.2% of the total. In 2003–2011, the export trade volumes of all the industries increased, but the growth rates of less polluted industries are higher than that of heavy polluted industries. Based on the above findings, the paper also proposed some policy recommendations.

Embodied Carbon Emissions and Regional Transfer Characteristics—Evidence from China

“…The decrease in emission intensity during the study period resulted in 52.58% of the net carbon emission decrease. Therefore, the carbon intensity of production must be reduced by stimulating innovation and improving production technologies to reduce carbon emissions at their source [46]. Policymakers will be able to establish special funds to support the research of new technologies, such as energy conservation, emission reduction, and clean production.…”

Transfer Characteristics of Embodied Carbon Emissions in Export Trade—Evidence from China

“…The factors that drive carbon emissions will shift with economic development, and the predominant factor that restrains the increase in emissions is always the technological effect. Consequently, technological innovation is essential for reducing carbon dioxide emissions [64,65].…”
