我国进口LNG长协和现货贸易价格与国际原油价格有着密切的关系,本文以2014年下半年至今布伦特原油价格、日本JCC原油价格、我国LNG长协和现货到岸价格为研究对象,通过图形模拟和CORREL函数计算相关系数的方法分析,得出日本JCC原油价格一般比ICE brent原油价格延迟调整3-5个月,我国LNG长协和现货到岸价格与国际油价息息相关。
The price of long LNG import and spot trade in China is closely related to the international crude oil price. In this paper, the price of Brent crude oil in Japan from the second half of 2014 to the present, JCC crude oil price in Japan, the long LNG contract in China and the CIF value in the spot market are studied. And CORREL function to calculate the correlation coefficient, it is concluded that the price of Japanese JCC crude oil is generally 3-5 months delayed than the price of ICE brent crude oil. The long-term LNG contract and spot CIF value in China are closely related to the international oil price.
