『Abstract
As the world's top energy consumer, China is facing a great challenge
to solve its energy supply issue. In this paper energy use from
all industrial sectors in China's economy of 2007 was explored
by conducting an extended environmental input-output analysis.
We compare the energy consumption embodied in the final demand
for goods and services from 29 sectors with the energy demand
required for the actual production process in each sector. Two
different viewpoints for sectoral energy use have been presented:
energy use is directly allocated to the producer entity, and energy
use is reallocated to sector's supply chain from consumption perspective.
Our results show that considerable amount of energy use is embodied
in the supply chain, especially for “Construction” and “Other
Service Activities” sectors, which is not detected if energy use
is allocated on a production basis. When further dividing embodied
energy consumption into direct energy consumption and indirect
energy consumption, total indirect energy consumption is much
higher than that of total direct energy consumption, accounting
for 80.6% of total embodied energy consumption in 2007. Our results
provide a more holistic picture on sectoral energy consumption
and therefore can help decision-makers make more appropriate policies.
