The Calculation And Factor Analysis Of Complete Household Consumption Activities On Carbon Emission In China

For a long time, the researchers have been focusing more on the energy-savingpolicies in industrial field than in household sector. However, being the terminal ofindustry chain, household activities influence energy consumption and carbon emissiongreatly by two ways: the fist one is to consume energy products directly, while the otherone is to consume non-energy products which depletes energy products indirectly. Sothe paper intends to discuss the estimation and factors of the complete carbon ofChinese residents, and try to put forward some effective carbon reduction policies.The paper breaks down complete carbon emission from household into two parts:direct one and indirect one.The consumption amount of different energies multiplies thecarbon emission factors then sum them respectively is the amount of direct carbonemission, while the total of the indirect one is calculated by the input-output method,which is on the base of Environment-Input-Output tables at constant price from1997to2007and measures the sum of the indirect carbon emission from city and countryhouseholds in two situations according to whether considering the income factors or not,The paper utilizes LMDI method to discuss influence factors and the degree of impactrespectively in whole country, urban and rural cases.The result shows that the total household carbon emission changed from61.7%in1997to78.5%in2007, and the percentage of urban and rural indirect carbon emissionis about85%and43%respectively. Till2007, the dwelling expenditure has become thelargest share of what depleted the indirect one of rural inhabitants,and it’s No.2in theurban case. The sum of the indirect one caused by transportation, communication,education and recreation has increased rapidly in recent years. The amount of carbonemission from high income groups is above2times more than that from low incomegroups. Among all the factors, the total population, per capita income, the expenditurewillingness and the structure of consumption can drive household carbon emission totalnumber, while the carbon emission intensity multiplier, energy intensity multiplier of eightkinds of consumption and the structure of energy consumption restrain it. Besides, asthe driving factors are more powerful than the restrain ones, the indirect carbon emission amount tended to increase in the past years.According to the features of household carbon emission, the paper gives four adivce:optimize the consumption patterns of life, make clear of the responsibility for carbonemission, and enhance the level of technique.
