Research on Carbon Emission of Residents ’ Consumption — Based on the City of Guangzhou

Carbon dioxide can cause greenhouse effects and that have a bad effect on the lives of residents. With the continuous improvement of economic development level, the consumption structure of residents is also changing, and then the carbon dioxide emission produced by residents is also changing. Therefore, this paper used LMDI decomposition method to calculate and analyze the indirect energy consumption of Guangzhou residents carbon emissions, which creatively used the LMDI method in the study of urban residents on the carbon emissions. At the same time, the research of this paper is helpful to strengthen the residents’ awareness of carbon emission reduction. This paper first explored the factors that affect the indirect energy carbon emissions of residents, then defined the research frame of residents’ indirect energy carbon emission, and therefore accounted for the indirect energy consumption of residents. According to the demographic characteristics of the population of Guangzhou, the emission from residents’ carbon consumption is further divided into urban consumer carbon emissions and rural consumer carbon emissions. The research results are as follows: The main factor that stimulates the carbon dioxide emission of Guangzhou’s residential indirect energy consumption is per capita income; the main factor that suppresses the emission is the intensity of energy consumption Population size, per capita income, and the resident consumption structure have a stimulating effect on the emissions of carbon dioxide from Guangzhou’s residential indirect energy consumption of urban and rural residents. The intensity of energy consumption and the emission intensity of carbon dioxide have a suppressing effect on the emissions of carbon dioxide from Guangzhou’s residential indirect energy consumption of urban and rural residents. Urban and rural population structure has a stimulating effect on the emissions of carbon dioxide from Guangzhou’s residential indirect energy consumption of urban residents, but has a suppressing effect on rural residents.

Introduction
Chinese government has set a strategic goal of reducing carbon intensity by 40% to 45% by 2020.Carbon dioxide is the most important part of greenhouse gases, and human activities produce carbon dioxide.Climate warming will cause heat wave invasion, changes in the pattern of drought and flood.Environment we live and our social economic development will have a serious impact.
China's carbon emissions research has made rapid progress since 2006.However, China's research on carbon emissions is mainly focused on reducing carbon emissions in high energy-consuming industries, ignoring the impact of consumer spending on carbon emissions.With the rapid development of China's economy and the continuous transformation of society, China's consumption patterns continue to change, the resulting carbon emissions are changing.
Therefore, to explore the issue of consumer carbon emissions, is conducive to strengthening our understanding of consumer carbon emissions, is conducive to improving China's carbon emission reduction policies and decision-making targeted and operational.
As to the study of residents of indirect living energy consumption growth factors, Li Yanmei et al. [1] implied input-output method research.Feng Ling et al. [2] used the CLA method to quantify the indirect energy consumption and carbon emission changes of urban residents in China from 1999 to 2007, and analyzed their potential influencing factors.Yao Liang et al. [3] used the LCA method to account for the implied carbon emissions of residents in China in 1997, 2002 and 2007.Zhang Jilu [4] implied factor decomposition method to analyze China's domestic consumption of indirect carbon emissions, and analysis of domestic consumption of carbon emissions factors and the impact of each factor.Therefore, this paper uses LMDI decomposition method, the urban level as a research perspective, with originality.Considering that most of the previous studies have focused on the carbon footprint of energy consumption [5], this paper focuses on the carbon emissions of indirect energy consumption.

Research Methods
LMDI (logarithmic mean weight division index method) is the use of timing variables of the two endpoints of the logarithmic average as the decomposition of the weight ratio, the weight Equation is: Substituted the weight equation into the exponential decomposition formula: ) ( ) From the above equation we can see that LMDI is a complete decomposition method, it will not produce residuals, the data contains zero is no problem.At the same time, due to the characteristics of exponential operations, LMDI is divided into multiplication and decomposition of two, two forms can be converted between each other.

Data Source
At present, China's energy intensity and carbon intensity are measured using energy intensity and carbon intensity per unit of GDP.However, this paper does not simply compare the eight consumer expenditure contents with the energy consumption and output data of the China Energy Statistical Yearbook, but rather 18 industrial sectors related to these consumer expenditure contents (among the industry sectors corresponding to the consumption expenditure contents) are selected from 23 industrialized sub-sectors in Guangzhou Statistical Yearbook (form 2003-2014) (see Table 1).Guangzhou residents consumption expenditure projects and production departments linked.The energy intensity and carbon intensity of consumption expenditure are calculated as follows: , , , , ,

represent CO 2 Emission intensity in Guangzhou, representing the Guangzhou energy structure and CO 2 emission coefficient.
Therefore, the amount of change in CO 2 emissions can be broken down into: , represent the contribution of six factors, such as population size, urban and rural population structure, per capita consumption level, residents' consumption structure, energy consumption intensity and CO2emission intensity.Use R and 0 to represent two comparison objects, according to the LMDI method, CO 2 emissions change can express: The above formula 6 variables for different residents living consumption of CO2specific formula is as follows:

We should look at this form from the following point of view: A positive numbers indicate a stimulating effect, the bigger the value, the stronger the stimulating effect.A negative number indicates a repressive effect, the bigger the absolute value of the negative number, the stronger the inhibitory effect.
From Table 2 we can see that, on the whole, population size, urban and rural

Influencing Factors of Indirect energy Consumption in Guangzhou Residents
The comparison of the influencing factors of indirect energy consumption CO 2 consumption between urban residents and rural residents in Guangzhou, we can see that, on the whole, the population size, the level of per capita consumption, the consumption structure of residents in Guangzhou urban and rural residents living energy consumption of CO 2 emissions are stimulated, energy consumption intensity, CO 2 emission intensity of Guangzhou urban and rural residents indirect energy consumption CO 2 emissions Have an inhibitory effect.Urban and rural population structure of urban residents in Guangzhou City, indirect energy consumption of CO 2 emissions have stimulated the role of urban residents in Guangzhou City, indirect energy consumption of CO 2 emissions have an inhibitory effect.This is due to the increase in the number of rural residents as a result of the increasing population of urban residents, so that the urban and rural population structure has an inhibitory effect on CO 2 emissions from rural residents' indirect energy consumption.

Conclusion
On the whole, the population size, the per capita consumption level and the consumption structure of the residents are stimulating the indirect energy con-
