An Empirical Analysis of China’s Energy Security Based on TOPSIS Model

Within the last twenty years, China has become a net importer of coal, oil and natural gas. China’s energy security becomes increasingly important. The paper analysed the energy production and consumption of China, and described the change of China’s energy security strategy. This research constructed an evaluation system from five dimensions of reserve security, production and transmission security, trade security, consumption security and sustainability. By adopting the grey related TOPSIS model, the research examined the energy security level of China from 2005 and 2019. The paper proposed countermeasures and suggestions to improve energy security level of China.
