| Since the 1990s, global warming has become a hot topic and concerned by all countries around the world, while global warming is mainly due to increased carbon dioxide emissions from human activity, therefore, reducing carbon dioxide emissions, preventing global warming has become the common responsibility of mankind. China, as the world’s largest developing country. In 2009, its annual carbon emissions exceeded the United States and become the first carbon-emitting country, and there is a huge pressure in response to global warming. Therefore, studying our country’s current carbon emission fluctuation situation and influence factors from the perspective of production and consumption, so as to develop corresponding policies and suggestions for our country’s low carbon development is very important.Based on 2002-2010 comparable price input-output tables, in this paper, we first calculate the carbon emissions of China’s industrial sectors with three components by an input-output subsystems, next, we decompose the three components into effect of carbon emission intensity, effect of social technology and effect of final demand separately by structure decomposition analysis, at last, analyzing the contribution of every effects to the total emissions by sectors, so finding the key sectors and key factors which induce the changes of carbon emissions in China’s industrial sectors. In addition, Carbon emissions caused by residential consumption have become one of the main sources of carbon emission and reveal a huge growth trend in China. By processing data of Chinese input-output tables available and relative Statistical Yearbook, this paper uses RAS method to update the input-output tables to obtain the time series input-output tables from 2002 to 2011. Then, we use input-output method to make a contrastive analysis of changes in carbon emissions caused by Chinese rural and urban residents’ consumption.The research of our country’s industrial sectors’ carbon emission influence factors show that during the year of 2002 and 2010, the following five departments increase the most in carbon emissions that are transportation equipment, manufacture of general and special purpose machinery, manufacture of electrical machinery and equipment, manufacture of communication equipment computers and other electronic equipment, manufacture of foods and tobacco; and the effect of final demand is the key factors leading to the increase of industrial total carbon emissions. By compared of these two periods, we find that the final demand factors caused a further increase in carbon emissions, while the effect of carbon emission intensity was made a positive contribution to the reduction of carbon emissions, and social technology on the reduction of carbon emissions did not play a very good effect, pending further improved.The research of the fluctuations of carbon emissions from residential consumption show that he total indirect carbon emissions caused by Chinese residents’ consumption increase year by year, but its proportion of the total national carbon emissions caused by energy consumption declines with time. The indirect carbon emission caused by urban residents’ consumption is the main part of carbon emission caused by residents’ consumption, and the gap between carbon emission caused by urban and rural residents’ consumption is wider and wider. The annual per capita indirect carbon emissions in urban and rural areas increase by years, and the increment of the town is much greater than that of the country. But since 2004, the annual increasing rate of carbon emissions of the town has been smaller than that of the country. According to industries, we find that the carbon emissions generated by the urban residential consumption of products of primary industry and secondary industry are reduce year by year, while carbon emissions produced by the consumption of the products of third industry are increasing gradually. However, the rural residents’ consumption is mainly concentrated on the products of second industry. Finally, in accordance with the above conclusions, the paper puts forward some countermeasures and suggestions from the perspective of production and consumption. |
