Perspective of China's energy strategy from world trend based on a combined Fuzzy-Logarithmic and Fuzzy-Topsis method

The downward pressure of the world economy is increasing, with a rising populism tends and geopolitics turbulence. The emerging economy led by China turns into the main body of energy market increment. The global energy supply and demand pattern is undergoing profound changes, which makes energy strategy more and more important. Based on the evolution practice analysis of energy strategy in typical countries proposed by our team, several important paths of energy strategy in China are identified firstly. Meanwhile, a combined Fuzzy-Logarithmic and Fuzzy-Topsis method is proposed in this paper in order to rank the key points of energy strategy, especially considering the energy strategy issues are always complex and difficult to quantify. Finally, seven strategy paths are evaluated by priority, which are demanded-oriented reform, mitigating institutional mechanisms contradictions, energy technology breakthrough, global energy governance, energy enterprise synthesis strength improvement, energy finance system construction and integrated energy system construction. It is expected that the advice proposed in this paper is beneficial to our energy industry.
