国际油价与石油公司业绩分析——以中海油、中石油、中石化为例

The Empirical Analysis on International Oil Price and Domestic Oil Companies Performance——CNOOC,PetroChina,Sinopec

20世纪后半叶以来,国际油价波动剧烈,深深影响着我国石油公司的业绩乃至整个国民经济。在分析近十年的国际油价和国内三大石油公司的业绩基础上,构建出油价-公司业绩的二次曲线模型,结果表明:稳定在40-60美元/桶的油价是三大石油公司业绩最优区间。

Since the last second half of the 20th century, the international oil price has soared to a rather high level. This deeply affected the performance of Chinese oil companies, and even the entire national economy. By studying about 10 years of international oil price and domestic performance of three major oil companies, the paper builds a set of the quadratic curve models （ oil prices - corporate performance ）, and make a quadratic regression graphics. It concludes that the oil price staying at the 40 - 60 dollars per barrel is the best price interval for the optimal performance of these oil companies.
