As the economic scale continues to grow, issues related China's energy supply security have become increasingly severe. Energy remains a crucial concern in development. Especially face of international turmoil recent years, for China, an economy with high dependence on foreign energy, risk stability is inevitably transmitted other fields, causing series problems. This study quantitatively evaluates over period from 2013 2022. Based 35 specific indicators industry, index system security, comprising four dimensions – production, consumption, environmental impact, and TOPSIS (Technique Order Preference by Similarity Ideal Solution) entropy method, has been adopted. The results show that overall condition China at upper-middle level, notable differences across various dimensions. coordination faces challenges due multiple factors. In terms production China’s exhibits relatively higher levels sustainable development, while environment significantly more difficulties, revealing urgency development sector: under dual pressures maintaining growth as well protecting environment, increasing policy support renewable industry its share consumption structure feasible solution.
