東北寒地區(qū)域碳排放現(xiàn)狀評價及影響因素研究
[Abstract]:With the rapid development of social economy and the gradual improvement of people's life, energy consumption is also increasing day by day. As a direct product of energy consumption, the level of carbon dioxide emissions is also rising sharply. The resulting Greenhouse Effect influences people's lives in various ways. Global warming, sea level rise, biodiversity loss, ozone hole, extreme weather and other words are more and more in the field of view. All kinds of natural disasters make the world realize that it is necessary to control the carbon emissions in the process of economic development. As a developing country, China is faced with great pressure before the current task of reducing carbon emissions worldwide. Heilongjiang Province, Jilin Province and Liaoning Province, as typical northeast cold regions, are also the cradle of China's industrial development, and have contributed a particularly important force to the economic and social development in the early years of the founding of the people's Republic of China, but under the present technological conditions, The industrial structure is still dominated by industry, the technology is relatively backward and the energy efficiency is not high, which is very disadvantageous to the completion of the task of emission reduction in our country. Therefore, it is necessary to evaluate the current situation of regional carbon emissions and to clarify the influencing factors. Based on the carbon footprint method and TaPio decoupling method, this paper analyzes the current situation of carbon emissions in the northeast cold region from the perspectives of total amount and productivity. The total amount of analysis shows that the carbon footprint of northeast cold region increases gradually. And from the increasing trend in the future, through the carbon footprint density, carbon footprint ecological pressure, carbon footprint output value, carbon footprint intensity and other indicators of the current carbon footprint impact on the ecological environment. The results showed that the CFD indices were all greater than 3 EPICF indices, which indicated that the environmental pressure was high and the future growth trend was higher, while the slow growth of VCF index showed that the CFI index decreased slowly, which indicated that the impact of technology on carbon emissions was not high, and the decrease of unit energy consumption was slow. The results of productivity show that the level of carbon utilization in northeast cold region is not high and is in the stage of weak positive efficiency. In terms of overall level, the carbon productivity of Liaoning Province is the highest, that of Jilin Province is the second, and that of Heilongjiang Province is the lowest. But Jilin Province carbon productivity has a downward trend. The factor decomposition analysis of carbon emissions by LMDI factor decomposition model shows that the economic growth effect and population scale effect are the main driving factors of regional carbon emissions, and the energy intensity effect is the main restraining factor of regional carbon emissions. The contribution direction of industrial structure effect and energy structure effect in Heilongjiang province, Jilin province and Liaoning province is different. The effects of industrial structure on carbon emissions were inhibited in Heilongjiang province, pulled in Jilin province and Liaoning province, pulled by energy structure factors, and inhibited in Jilin province and Liaoning province. The results of decomposition analysis are explained according to the current situation of each province, and the reasons for the differences are clarified. Through the evaluation of the status quo of carbon emissions in the northeast cold region, the factors influencing the formation of the present situation are made clear by the decomposition analysis method and the actual situation in Heilongjiang, Jilin and Liaoning provinces. Based on the above analysis, this paper focuses on the adjustment of industrial structure, optimization of energy structure, application of low-carbon technology, enhancement of ecological protection, and overall planning for development. It provides scientific and reasonable support for the successful completion of the task of energy saving and emission reduction in the Northeast Cold region during the 12th Five-Year Plan.
