Evolution of Final Demand Pattern,Changes in Industrial Structure and CO_2 Emission in China——Based on Input-output Model and SDA Method
In this paper,CO2 emissions from final consumption,investment and export during 2002-2010 are calculated and the functions of final demand pattern and industrial structure in CO2 emissions are analyzed based on the input-output model;then the impacts on the CO2 emissions are examined by the structural decomposition method.Results show that the roles of the three kinds of final demand in pulling CO2 emissions are quite different;in order of most polluting in absolute quantity it goes: investment,consumption and export;and investment,export and consumption in pollution increment;this phenomenon is closely related with the industrial structure.This paper proposes that expanding consumer demand helps to realize the two major goals of industrial structure optimization and emission reduction.
