摘要
基于协整理论研究了钼价格与国民生产总值、钢铁产量之间的长期均衡关系,并构建长期均衡协整模型和误差修正模型对钼价格进行预测。结果表明,钼价格与国民生产总值、钢铁产量之间存在协整关系;误差修正模型比长期均衡协整模型具有更高的预测精度。通过模型预测2016年的钼价格可知,未来一年内钼价格将持续走低,2016年钼价格将降至615元/吨度。
Based on cointegration theory,the long-term equilibrium relationship was investigated between molybdenum price and gross national product or steel production.And a long-term equilibrium cointegration model and an error correction model were established to predict molybdenum price.The results show that the three variables have cointegration relationship.Error correction model has higher prediction precision than long-term equilibrium cointegration model.The predicted results with the above models for molybdenum price in 2016 indicate that molybdenum price will continue to decline to 615 yuan per mtu within the next year.
