『Abstract
Trades create a mechanism of embodied CO2
emissions transfer among regions, causing distortion on the total
emissions. As the world's second largest economy, China has a
large scale of trade, which results in the serious problem of
embodied CO2 emissions transfer.This paper
analyzes the characteristics of China's CO2
emissions embodied in international and interprovincial trade
from the provincial perspective. The multi-regional Input-Output
Model is used to clarify provincial CO2 emissions
from geographical and sectoral dimensions, including 30 provinces
and 28 sectors. Two calculating principles (production accounting
principle and consumption accounting principle, Munksgaard and
Pedersen 2001) are applied. The results show that for international
trade, the eastern areas accounts for a large proportion in China's
embodied CO2 emissions. The sectors as net
exporters and importers of embodied CO2 emissions
belong to labor-intensive and energy-intensive industries, respectively.
For interprovincial trade, the net transfer of embodied CO2 emissions is from the eastern area to the central
area, and energy-intensive industries are the main contributors.
With the largest amount of direct CO2 emissions,
the eastern area plays an important role in CO2
emissions reduction. The central and western areas need supportive
policies to avoid the transfer of industries with high emissions.
