Abstract: China’s coal-dominated energy structure cannot be changed in a short period of time because the nation's resources are characterized zed in“ abundant coal, shortage of oil and inadequate quantity of gas”. Appropriate development of the coal-to-oil industry by means of innovative technology is of great strategic significance to solving China’s shortage of oil resources and securing the country’s energy supply. China has made a substantial progress in its coal-to-oil industry in recent years. The sector is satisfactory for its scale and economic performance. Particularly, the important breakthroughs were made in independent research and development of key coal-to-oil technology and equipment, enabling the nation to stand on the world’s forefront. However, the country still faces some problems, such as the prices of coal and oil, water consumption, energy consumption, and operational cost of investment. From the viewpoint of long-term development, coal-to-oil can be used as an important way for the nation to improve its independent capacity to secure oil supply in the emergency cases. In the principles of“ focusing on technology ahead of time, bringing the total volume under control and pursuing a healthy development”, this sector is supposed to develop itself in harmony with traditional energy, in coupling with the clean energy industrial distribution, in healthy reciprocation with traditional petrochemical industry, and in production of a new CCUS momentum. The coal-to-oil sector can fully maintain the nation’s energy security if necessary. At the usual time, oil products and chemicals should be brought under unified arrangement and produced jointly according to the market demands, and switch flexibly to keep the operational sustainability of coal-to-oil facilities.
