Research On The Level Of Economic Development, Industrial Diversification Andcarbon Emissions Relations In The Three Northeastern Provinces Of China

China’s economy is in a stage of rapid development, a large number of primary energy consumption, and make our country become the most carbon dioxide emitter. Rising carbon dioxide emissions will cause a series of environmental problems such as global warming, so the control and reduce the amount of carbon dioxide, the development of low carbon economy is the common goal of all countries.First, this paper introduces the research background and the significance of the research, and detailed combing the status of carbon emissions at home and abroad. This paper explains the theory of the low carbon economy and decoupling. This article also explains the natural geographical and social economic aspects of the study area, and summarizes the general research of area of three provinces in Northeast China. This paper uses IPCC emission coefficient to calculate carbon emission for Heilongjiang, Jilin, and Liaoning provinces respectively from 1980 to 2012. To analysis of the difference, this research draws the Northeast three provinces 33 years of carbon emissions and primary energy consumption synchronous change and fluctuating upward trend. This research also analyze changes in the structure of the primary energy consumption in Heilongjiang, Jilin, and Liaoning provinces to change the structure of energy consumption can slowed down the carbon emission.Second, this paper then uses SPSS software and Eviews software for data ADF stationary test and co-integration test showed that the three northeastern provinces of carbon emissions and GDP have a significant correlation. This paper uses Tapio decoupling model to analyze the relationship between economic growth and the northeastern provinces of carbon emissions between the years from 1980 to 2012. Results how that three northeastern provinces in the early 80 s of the 20 th century decoupled state changed significantly slower economic growth in 1990-2000, with a strong focus of the decoupling time period. The years of 2003 and 2004 show increasing trends, mainly because of the revitalizing the northeast old industrial base policy to accelerate economic development in Northeast China, because of coal consumption increased, and the amount of carbon dioxide increases. During the year of 2005 to 2010, a series of low-carbon reduction targets policy were introduced, northeast respond positively to this time period as a whole which showed a weak decoupling coefficient close to zero.Third, this paper uses a diversified industrial structure factor(MESD) analysis of the impact of industrial structure on carbon emissions to come to a conclusion that 1980-2012 MESD grows fluctuant. Results show that Liaoning province has MESF maximum 0f 10.3 in 2012, followed by Jilin province of 7.4, and Heilongjiang has the minimum of 6.3. MESD value increases every year, that is, the higher the degree of diversification of the industrial structure, while reducing carbon emissions growth rate was fluctuating, showing asynchronous features.Finally, the above conclusion, the different characteristics for the three northeastern provinces, made several recommendations Northeast development. 1) The adjustment of energy consumption structure; 2) to improve energy efficiency; 3) optimize the industrial structure, enhance the proportion of tertiary industry; 4) to continue to develop low-carbon economy...
