Discussion of China's Energy Security in the New World Energy Pattern

Since 2000,many new changes and problems have emerged in the world's energy industry,which means the world energy pattern is undergoing structural adjustment. The broad understanding of energy security mainly contains energy supply capacity energy consumption structure,energy consumption intensity,environmental issues caused by energy consumption,energy trade security and so on. The 16 classification indexs related to the above issues are discussed in this paper with the horizontal and longitudinal comparison of historical conceptions and worldviews. The results show that energy self-sufficiency rate in China would keep over 75% before2040,so there could be enough time to adjust macro energy strategy. Given that coal is dominant in China's energy consumption structure,it consequently leads to a series of environmental problems,especially greenhouse-gas emissions and PM2. 5emissions have been serious. In the long run,there is no problem with the capability to pay the net import of energy in China. China's energy imports are mostly from the Middle East,so China should pay close attention to the situation in the Middle East. Mean while,China should focus on the diversification in energy import sources.
