摘要
为了揭示我国煤炭价格是否对我国经济发展造成影响,本文利用Eviews软件对我国1991-2011年间的煤炭价格与GDP进行了ADF平稳性检验、Johansen协整检验、Granger因果检验并构建了VAR模型。通过软件输出结果可准确得出:煤炭价格与GDP存在长期的互为因果的正向均衡关系,且我国GDP水平对煤炭价格水平的因果关系比我国煤炭价格水平对我国GDP水平的因果关系更具有显著影响。
In order to reveal whether China coal prices affect the economic development, this paper use Eviews software to have ADF test, Johansen cointegration test and Granger causality test for China coal prices and GDP during 1990-2011. The Eviews software output accurately shows that the coal prices and GDP of our country have a positive equilibrium and causality relationship. Meanwhile, the China GDP have more significant causality to the coal prices than China coal prices to GDP.
