Abstract: In recent years, the low oil prices in international and domestic market have made significant impacts on the production and management of oil enterprises. Currently, China, one of the world's major oil producers and importers, is now faced with unprecedented challenges. Faced with fierce competition in the complex international market, China must carry on scientific evaluation on the competition of its oil enterprises in the international market in order to formulate corresponding countermeasures. Using factor analysis and taking into consideration the characteristics of China' soil enterprises, we establish the evaluation index system of international competition of oil enterprises with representative parameters such as overall strength, profitability, ability of resource development and production, sustainable development, internationalization level. Application of this system to the analysis of international competition of China' soil enterprises reveals that Chinese oil enterprises are relatively weak in international operation and profitability, which means we should vigorously implement the" Go Out policy" and actively integrate corporate strength and global resources so as to promote the international competition of oil enterprises in China.
