Abstract:On the premise of advocating low-carbon economy and energy saving and emission reduction in the central provincial administrative region vigorously, Hunan non-ferrous metal mining industry is facing tremendous pressure of energy saving and emission reduction. In this study, grey relational analysis method was used to research the influence factors of carbon emissions in non-ferrous metal mining and dressing industry in Hunan Province from 2010 to 2017 from three aspects: economic development, industry development and energy consumption. By comparing the correlation degree, it is concluded that energy scale, the number of non-ferrous metal mining and dressing enterprises, energy intensity, economic growth, the proportion of secondary industry and energy structure are the key factors affecting the carbon emissions of Hunan non-ferrous metal mining and dressing industry. Then the paper puts forward some policy suggestions, such as using clean energy to improve energy consumption ratio, reducing quantity and increasing quality to achieve intensive development, improving enterprise development environment and promoting deep processing of resources and so on.
