摘要
2002—2006年石油与黄金产业价格变动之间的关系可以用格兰杰因果关系进行检验,并根据格兰杰表示定理建立石油与黄金价格联动之间的误差修正模型来考察二者之间的长期关系和动态关系。本文认为石油价格和黄金价格上涨之间是单向的,从石油价格上涨到黄金价格上涨的因果关系,而且这种关系是长期稳定的,并没有随时间而发生结构性变化。
Using co - integration technique, we examine the causal relationship between international prices of petroleum industry and that of gold industry over the period from 2002 to 2006. Based on the Granger Representation Theorem, we set up an error correction model to investigate the long - run and dynamic relationship between them. Empirical results show that a long - run stable unidirectional causality running from prices of petroleum industry to prices of gold industry.
