运用协整检验的方法,分别对2006—2016年山西省产地煤炭价格、消费地煤炭市场价格与山西省煤炭企业吨煤成本之间的长期关系进行了实证检验。结果表明,山西省产地煤炭价格与山西省煤炭企业吨煤成本、消费地煤炭市场价格与山西省煤炭企业吨煤成本之间的协整关系均存在,且山西省企业吨煤成本对山西省产地煤炭价格的影响和对消费地煤炭市场价格的影响相比,影响程度明显较强。
By means of cointegration test, this paper empirically tests the long-term relationship between the coal price of origin in Shanxi province, the coal market in consumer area and the coal cost of coal enterprises in Shanxi Province from 2006 to 2016 respectively.
