China's Energy Import Market Structure and Its Effects on Energy Security

Energy is an important strategic resource of a country, and its stable supply is of great importance to the security of a country, especially economic security. Due to diversification, stability is the basic view of ecology. Based on the market concentration index and diversity index in industrial economics and information economics, this paper analyzed the market structure of China's major energy import, and then calculated the dependence coefficient of China on the main sources of energy import. The results showed that China's import market structure of oil, coal and natural gas is highly concentrated, and different sources of energy import vary in the price. If the export space of international energy market can be fully used, China's energy security and its status in the trade negotiations with some energy export countries can be further improved to reduce energy import prices and improve energy trade terms.
