| Coal is the cornerstone of China’s energy.In the future,China’s coal-based consumption structure will not change.However,under the background of ecological civilization construction,the traditional coal industry development mode no longer meets the needs of economic development in the new era.It is urgent to explore the path of transformation and upgrading to achieve sustainable development of the coal industry.China’s 13 th five-year plan for national economic and social development proposes to optimize the energy supply structure while improving the energy utilization efficiency,and build a clean,low-carbon,safe and efficient modern energy system.Due to the different stages of economic development,different energy consumption structures,and different environmental carrying capacity in different regions of China,the process of coal industry upgrading needs to consider space optimization issues.The "Thirteenth Five-Year Plan" for the development of the coal industry also stated that it is necessary to combine industrial upgrading with space layout optimition.Therefore,this thesis systematically studies the transformation and upgrading of coal industry and the optimization of space distribution.In this paper to explore the relationship between coal consumption and economic development and the typical case,on the basis of the transformation and upgrading of national coal based on the analysis of China’s coal industry history and status quo,on the basis of combing transformation and upgrading of China’s coal industry and the problems existing in the spatial layout,and then from two dimensions to establish a technical and economic and ecological efficiency evaluation model,considering the coal industry economy and environmental compatibility,on the basis of finding out the match with the provincial economy development stage and the environmental capacity of the coal industry,the traditional coal,efficient coal-fired electricity,coal,oil and gas and the modern coal chemical industry in the provinces for layout,combined with China’s actual conditions finally,Put forward the optimization strategy of coal industry structure and space distribution in China.The main conclusions of this thesis include:(1)The transformation and upgrading of developed countries’ coal industries often appear in the middle and late stages of industrialization.The transformation methods are mainly industrial upgrading and technological upgrading.In addition to subjective restrictions on coal consumption,the use of high-efficiency coal-fired power generation to save coal,and the development of coal chemical industry will extend the industrial chain,shifting from the traditional use of fuel to a way of focusing on both fuel and raw materials.(2)The ecological utilization efficiency of coal in coastal provinces is higher than that in the central and western regions,and the ecological utilization efficiency of coal in large economic endowment provinces is higher than that of large coal resource endowment provinces.(3)Among the emerging industries,the contribution rate of coal-to-gas and coal-to-liquid technological progress exceeds 40%,which together with capital investment has become the main driving force for industrial development.(4)In the short term,the increase of coal-to-liquids and coal-to-gas industries will not be able to offset the slowed down development of traditional coal industries due to overcapacity,energy structure adjustment and other reasons.Efficient coal-fired power generation is the most effective supplement to accelerate the transition from traditional energy to clean energy in short-term.(5)By The coal industry layout of major regions in China in the future is divided into three categories: 1)key development categories: Inner Mongolia,Shaanxi,Shanxi,Xinjiang,Shandong,Hebei,Anhui and Guizhou;2)Gradually adjusted categories: Liaoning,Hunan,Zhejiang,Henan,Qinghai,Ningxia,Gansu,Heilongjiang,Sichuan,Yunnan;3)Gradually withdraw category: Guangdong,Fujian,Jiangsu,Hubei,Hainan,Tianjin,Shanghai,Chongqing,Beijing,Guangxi,Jiangxi,Jilin,Zhejiang,Tibet.(6)By 2035,coal chemical industry in China’s coal industry will be an advantageous industry for key development,and the demand for coal power and coal power will basically maintain the current scale.However,due to the pressure of ecological protection and downward changes in the industry in the building materials industry and metallurgical industry,the demand for modern coal chemical industry and other industries will continue to decline.Industry demand is growing rapidly.At the same time,the coal industry structure of key development categories was optimized and researched. |
