【摘要】：随着生产力的不断发展，环境问题已成为人们共同面临的挑战。煤炭在燃烧过程中会产生二氧化硫等有毒气体和二氧化碳等温室气体，这些气体的大量排放，使得全球气候逐渐变暖，，大气环境遭到污染甚至带来了雾霾天气，这严重威胁着人类的生存和发展。因此，对于我国这样一个以煤为主要能源的国家，研究煤炭利用的环境影响和节能减排潜力，将会进一步丰富可持续发展理论，为我国合理分配节能减排目标提供重要的依据，将对我国实现碳减排承诺，解决环境污染问题、促进经济持续健康具有重要意义。本文使用我国2003-2012年的面板数据，通过面板单位根检验、面板协整检验、面板模型估计、面板格兰杰因果关系检验，分析我国煤炭利用对废气、二氧化硫和烟粉尘排放的环境影响；以火力发电和钢铁行业为例，通过燃煤发电能耗指标、燃煤供电能耗指标将我国火电行业的能耗与日本进行对比，通过吨钢综合能耗指标、工序能耗指标、吨钢可比能耗指标将我国钢铁行业的能耗与国际先进水平进行对比，测算了我国燃煤行业在煤炭利用环节的节能减排潜力。研究结果表明：我国的煤炭利用对环境污染造成了影响，尤其体现在大气污染方面，由于我国煤炭消费量基数比较大，积累的环境影响比较明显；同时发现我国燃煤行业的能耗较高，煤炭利用的节能减排潜力较大，通过煤炭利用环节的能源技术创新，可以实现节能减排，进而达到减少环境污染的目的。因此，我国需要通过能源技术创新，实施能源结构调整和提高煤炭利用效率双管齐下的能源政策。
[Abstract]:With the continuous development of productivity, environmental problems have become a common challenge. Coal combustion process will produce toxic gases such as sulfur dioxide and carbon dioxide, such as greenhouse gases, these gases emissions. The global climate is gradually warming, the atmospheric environment is polluted and even haze weather, which is a serious threat to the survival and development of human beings. Therefore, for our country, coal is the main energy source. To study the environmental impact of coal utilization and the potential of energy saving and emission reduction will further enrich the theory of sustainable development, provide an important basis for the rational allocation of energy saving and emission reduction targets in China, and achieve carbon emission reduction commitments to China. It is of great significance to solve the problem of environmental pollution and promote the sustainable health of economy. In this paper, we use the panel data from 2003-2012, through panel unit root test, panel cointegration test, panel model estimation, panel Granger causality test. The environmental impact of coal utilization on exhaust gas, sulfur dioxide and smoke dust emission in China is analyzed. Taking thermal power generation and iron and steel industry as an example, the energy consumption index of coal-fired power generation and coal-fired power supply industry is compared with that of Japan, and the energy consumption index of thermal power industry in China is compared with that of Japan. The comprehensive energy consumption index of tons of steel and the energy consumption index of working procedure are compared. The energy consumption of China's iron and steel industry is compared with the international advanced level, and the energy saving and emission reduction potential of coal burning industry in China is calculated by comparing the relative energy consumption index of tons of steel with that of the international advanced level. The results show that: the coal utilization in China has an impact on environmental pollution, especially in the air pollution, because the coal consumption base of our country is relatively large, the accumulated environmental impact is obvious; At the same time, it is found that the energy consumption of coal industry in China is high, the potential of energy saving and emission reduction of coal utilization is great, and energy saving and emission reduction can be realized through the innovation of energy technology in coal utilization link. In order to reduce environmental pollution, our country should adopt energy technology innovation, implement energy structure adjustment and improve coal utilization efficiency.
