Study On Relationship Between The Three Industries And Carbon Emission Of Poyang Lake Ecological Economic Zone And The Impact Factors Of Carbon Emission

In the situation of global climate change, low-carbon economy has become the trend of the world economy development. Poyang Lake Ecological Economic Zone is an ecological economy demonstration area that the ecology and environment develope coordinately with the economy and society. And it is also a low-carbon economy leading area that humanity get together with nature harmoniously. It shoulders the heavy responsibilities of both protecting "a lake of pure water" and leading the economic and social development in the region. The concept of "Ecological Economic Zone" determines the direction of its development, which is guided by the concept of ecological civilization, and takes the way of new industrialization development and promotes the development of ecological industry. Eco-economy and low-carbon economy is the same thing in their essence, they both require the efficient use of resources as well as energy savings and emission reduction. The most important sides of economic development is economic aggregate and structure. Their is always expansion of the economic aggregate together with the optimization and upgrading of the industrial structure when a region’s economy develope. The industrial structure, particularly the proportion relationship of the three industries, not only supports the current economic growth, but also determine the long-term economic development and the impact that the economic growth act on the society and environment. Therefore, in order to optimize the industrial structure of the Poyang Lake Ecological Economic Zone, and balance the development of economy and ecology as well as society and environment, the study of the relationship between the three industries and carbon emission is of great significance. Meantime, as an emerging ecological economic zone, the research of carbon emission of Poyang Lake Ecological Economic Zone is still in its infancy. In order to further study the influencing factors of the carbon emission so as to promote the long-term development of Poyang Lake Ecological Economic Zone, it is also essential to further study the influencing factors of the carbon emission of the economic zone. At first the article calculates and analyzes the carbon emission of the Poyang Lake Ecological Economic Zone, basing on the theory of carbon emissions. Then uses the gray relational analysis method to analyzes the correlation between the three industries of the Ecological Economic Zone and its carbon emission so as to provides theoretical references for the regional industrial structure optimization and carbon emission reduction. In order to study other influencing factors of carbon emission, Logarithmic Mean Division Index(LMDI) method is used to establish the factor decomposition model about the carbon emission of Poyang Ecological Economic Zone, analyzing the influences of the five factors, economic development, energy structure, regional output value distribution and population factor on carbon emission.The empirical results show that:in accordance with the corelation degree, the rank of the influencing degree that the added value of the three industries act on the carbon emission is, the secondary industry, the tertiary industry, the primary industry. Besides, the industrial added value has a great impact on carbon emission, which is even bigger than that of the tertiary industry and the primary industry. Therefor optimizing the industrial structure and improving industrial energy efficiency will show significant effect in carbon emission reduction. The decomposition analysis of carbon emission found that the largest contributor to carbon dioxide emission is the factor of economic development, the maximal inhibition factor is the energy intensity factor. The factors which play a role in promoting the growth of carbon dioxide emissions are:the economic development factor, population factor, energy structural factors and the factor of regional output value distribution; energy intensity factor is the only one factor that play role of inhibiting the growth of carbon dioxide emission. Thus, according to the different effects of these factors, the paper put forward various measures to reduce the carbon emission. Finally, based on the empirical analysis, combining with the socio-economic situation of the region, the paper propose suggestions for low-carbon development of the construction of Poyang Lake Ecological Economic Zone.
