The Influencing Factors And Transfer Mechanism Of Indirect CO₂ Emission Caused By Household Consumption In China

As the CO₂ emission from household consumption is an important source of CO₂ emission in the country, which occupies more than 40% of total CO₂ emission, this has caused more and more attention of scholars. In order to provide reference for the government to achieve targets of energy-saving and emission-reduction by adjusting the consumption structure and industrial structure, this paper uses the input-output method to measure indirect CO₂ caused by Chinese household consumption and study factors influencing it, then study its transfer mechanism. Specific contents are as follows:（1） In terms of the CO₂ emission measurement, this paper calculates the indirect CO₂ emission caused by Chinese household consumption from the two aspects of the national and sectoral levels. It is found that firstly, the indirect CO₂ emission is the main source of CO₂ emission caused by Chinese household consumption. Secondly, the CO₂ emission induced by per unit of urban household consumption is higher than that by per unit of rural household consumption. Thirdly, the eastern region produces the largest CO₂ emission.（2） In terms of factors affecting the CO₂ emission, this paper explores the factors influencing the indirect CO₂ caused by household consumption from the national and sectoral levels. The results show that, the indirect CO₂ emission is mainly driven by per capita household consumption and energy intensity, especially for sectors OTHERS, MFT, PDEH, WRHR, FFAF and TSP, whose CO₂ emission are influenced most.（3） In terms of transfer mechanism of CO₂ emission, this paper utilizes the Hypothetical Extraction Method（HEM） and the Multi Regional Input-Output（MRIO） respectively to study the sectoral and regional linkages of indirect CO₂ emission. The results show that, firstly, sectors of PDEH and SPM play the major role in pushing CO₂ emission of each sector in the national economy, and sectors of OTHERS and MFT are the key sectors in pulling CO₂ emission of each sector. Secondly, the multiplier effect of CO₂ emission in eastern region is the smallest and that in western region is the largest. The spillover effect of CO₂ emission in eastern region is the lowest and that in the central is the highest respectively. Total feedback effect in the central region is the biggest of all regions.
