摘要: 原油作为成品油的主要原材料,原油价格的变化会引起成品油价格的相应变化,从成品油价格关于原油价格变化的反应可以了解成品油定价的合理性.本文利用一个不对称的向量误差修正模型(Vector Error CorrectionModel,VECM),检验了我国汽柴油关于原油成本变化不对称性问题,检验结果表明,我国汽柴油对原油成本上涨的反应快,但持续的时间短;对原油成本下降的反应慢,但持续的时间长.研究结果对我国石油定价机制的改革和企业实施油价风险管理有参考价值.

关键词: 汽柴油价格, 原油, 不对称性, 向量误差修正模型(VECM)

Abstract: As petroleum products prime raw material,the change of crude oil price must cause the change of refined oil price.From the reaction,we could understand the rationality of refined oil pricing.In this paper,the anti-symmetry of gasoline/diesel to crude oil price fluctuation is investigated by using anti-symmetry VECM.Results show that the responses to crude oil price increase are quicker and transient,to crude oil price decrease are delayed and lasting.This study provides scientific supports on how to properly elude the risk incurred by oil price hike,as well as how to perform thorough reformation of China's oil price system.

Key words: gasoline/diesel price, crude oil, anti-symmetry, Vector Error Correction Model(VECM)
